Job opportunities in crop sciences are booming. Why? More than half of all crop scientists in industry and in government jobs will retire over the next decade.

A recent report by Purdue University and the U.S. Department of Agriculture’s National Institute of Food and Agriculture predicts more than 54,000 agriculture-related job openings annually between 2010 and 2015.

“There isn’t a better business to be in right now,” says Randy Smith, a member of the Weed Science Society of America and a field research and development leader for Dow AgroSciences. “Agricultural scientists have an opportunity to feed a hungry world and to write the next chapter in the ‘Green Revolution.’ It’s a cutting-edge profession and a noble calling.”

But despite the promising employment outlook, there is a talent shortage in the applied agricultural sciences. Data from the National Academies shows 4,010 baccalaureate degrees awarded in agriculture business and management in 2007 – but only 177 in crop production. A 2008 USDA review shows Bachelor’s degrees awarded in agronomy and the crop sciences decreased by almost a third between 1984 and 2003. Several universities have dropped or consolidated programs in the agricultural sciences because of low enrollment and dwindling funds.

“The issue of talent development in the agricultural sciences is a topic of paramount concern within higher education and industry circles,” says Emilio Oyarzabal, technology development manager, Monsanto. “There are many students pursuing degrees in the marketing, sales and business side of agriculture, but the number in the applied agricultural sciences is declining steadily.”

Oyarzabal and other experts say a number of intersecting trends are contributing to the dwindling talent pool. Publicly funded graduate assistantships have evaporated. Budget cuts, retirements and competition from higher-paying industry jobs have resulted in the steady drain of agricultural sciences faculty – the very individuals responsible for recruiting and training. Grant monies are pouring into molecular biology and other basic sciences – not into applied sciences like agriculture. One possible reason:

“There is a misperception that the agricultural sciences have matured and aren’t as exciting as some of the newer, emerging sciences, such as biotechnology and molecular biology,” says Roger Gast, product development leader, Dow AgroSciences. “But nothing could be further from the truth.”

Don Wyse, Ph.D., a professor of agronomy and plant genetics and director of the Center for Natural Resources and Agricultural Management at the University of Minnesota, says changing demographics also play a role.

“The number of students raised on a farm has plummeted, and we haven’t yet figured out how to engage and recruit students from urban communities,” he says. “The link between their lives and how their food is produced is really remote at best.”

Initiatives to build a sustainable agricultural workforce

What’s the solution? The Weed Science Society of America and nearly 30 other scientific societies and agricultural industry partners have begun to collaborate on ideas for building a sustainable agricultural workforce. Some of the proposed initiatives include:

• Promoting an awareness of career opportunities in the crop sciences.
• Building a pipeline of students in middle and high schools who are interested in pursuing degrees in applied and basic agricultural sciences.
• Generating awareness of the importance of sustainable agro-ecosystems and the crucial role of the agricultural sciences in feeding a growing world population.
• Funding scholarships to attract the best students into agricultural science studies and to support applied learning programs.
• Developing innovative recruitment and training programs to attract high-quality graduate students with leadership potential.

Most agree it will take a sustained investment of resources to reverse the talent shortage. And the need has never been more critical.

“To feed a growing population, experts predict we will need to produce more food over the next 40 years than we’ve produced over the past 10,000 years combined – and with diminishing land and water resources,” says Lee Van Wychen, Ph.D., science policy director of the Weed Science Society of America. “The stakes couldn’t be higher.”

Cotton growers looking at precision farming investments should check out the Cotton Precision Agriculture Investment Decision Aid (CPAIDA), created by University of Tennessee Production Economics Analysis Group.

The Cotton Precision Agriculture Investment Decision Aid (CPAIDA) is a stand alone, computerized decision tool for analyzing investments in precision agriculture technologies. It was developed to meet the need for better educational information about the returns required to pay for investments in precision agriculture technologies used by cotton farmers.

Currently available “payback” modules include map- and sensor-based variable rate application of sprayer-applied chemicals, sensor-based liquid nitrogen application, and sensor-based weed control. Additional modules for calculating the cost of gathering spatial information via electrical conductivity, yield monitor, and remote sensing are also provided. A distinctive sensitivity analysis feature allows users to evaluate a variety of “what if” scenarios for these technologies based on their particular farm characteristics.

The decision aid guides users through a systematic analysis of the precision farming investment decision via a set of clickable tabs and expandable menu options. The equipment information tab allows the user to select equipment components and enter purchase price.

Default equipment complements are set for each module, and users can click on cells to change equipment manufacturers or modify prices. The farm data tab lets users personalize the decision aid based on their unique farm situation, information gathering costs, and payback parameters which can include input cost savings, lint yield gain, and reduced equipment operating and ownership costs. The profitability summary tab displays results in the form of enterprise budgets that compare cost and return estimates with and without precision farming.

A final column indicates how individual cost items vary based on the precision farming investment decision and summarizes the expected profitability from adoption of the selected equipment complement.

Finally, a sensitivity analysis tab displays the results graphically. The main figure summarizes the profitability of the proposed equipment complement and provides an estimate of the payback period in years. Here, users can change key cost and return parameters, such as farm size or input savings, and evaluate how changes in these values influence the profitability of the investment decision.

The CPAIDA decision aid is also available at http://economics.ag.utk.edu/cpaida.html. Copies of CPAIDA on a CD ROM may also be obtained by writing James Larson, Department of Agricultural and Resource Economics, 2621 Morgan Circle, 302 Morgan Hall, Knoxville, TN 37996. This decision aid was funded by Cotton Incorporated.

University of North Dakota students and faculty designed and built the ISSAC camera to watch growing crops from space beginning in 2011.

“ISSAC is a space-related research project that will result in the delivery of direct benefits from space to the general public,” said Doug Olsen, ISSAC project manager. “The ISSAC project is in the midst of developing an upgrade to its camera sensor, which is expected to be launched in April 2011. It will resume operations during the 2011 growing season.”

ISSAC is designed to take frequent images, in visible and infrared light, of vegetated areas on the Earth, principally of growing crops, rangeland, grasslands, forests, and wetlands in the northern Great Plains and Rocky Mountain regions of the United States. Images will be delivered within two days directly to requesting farmers, ranchers, foresters, natural resource managers and tribal officials to help improve their environmental stewardship of the land. Images will also be shared with educators for classroom use.

The system allows users to select specific geographical areas of interest over which to request collection of imagery in both red and near-infrared bandpasses, and at medium-high spatial resolution. Farmers using variable-rate application and other precision agriculture techniques will be able to dynamically delineate management zones as the crop vegetation canopy changes during the growing season; this can result in more effective use of fertilizer and other chemical inputs and reduce negative environmental effects.

“The UND interdisciplinary effort that has produced this camera is a remarkable story,” said UND President Robert O. Kelley. “Faculty and students from several colleges and centers on campus have produced an instrument that will analyze the composition of agricultural and other natural resources on the surface of the earth from the International Space Station.”

“The consolidation of multiple technologies into a single instrument will add tremendous economic value to the agricultural industry in North Dakota and around the world,” Kelley said. “UND and NASA have forged a very productive partnership in this initiative.”

ISSAC is operated from the Science Operations Center (SOC) on the UND campus, staffed by students from across the campus, including from the John D. Odegard School of Aerospace Sciences and the School of Engineering and Mines. From the SOC, students will send commands to ISSAC to take images and transmit them to SOC, where they’ll be processed and delivered to end users. Images captured by the camera will be made available to the public through UMAC’s Web page (see http://www.umac.org/).

If you’re looking to experiment with corn planting populations yet this spring, check out a very good paper on plant population compiled by South Dakota State University researchers Gregg Carlson, Paul Gaspar and David Clay.

Many agronomists and producers conduct experiments that test the impact of rates of fertilizer, population, or pesticide on yield. To analyze this data we need to conduct a yield response analysis. Agronomists and or producers that understand yield response and how to use yield response to determine the point of optimum economic return will be able to make better management decisions. The point of optimum economic return is determined by:
1. Conducting a yield response experiment
2. Converting the yield response data to a functional relationship,
outputcorn yield = f(input the plant population)
3. Using calculus to determine where the change in the value of the input equals the change in the value of the output.
In site-specific farming, scientists have found that yield response relationships may change spatially and temporally.

To learn more, read the paper “Using Yield Response Analysis to Calculate an Optimum Plant Population“.

Ag Leader Technology and AutoFarm joined forces today in Ames, Iowa at the official opening of the new Ag Leader Academy to talk about their combined tools of precision agriculture with the media.

Matt Darr, Iowa State University

Amidst the talks by management, touting the excitement of this alliance and their complete precision farming product offering, was a presentation by Iowa State University agricultural engineer Matt Darr.

He paralleled the adoption curve of hybrid corn (which took 18 years) to grower adoption of precision farming tools. In 2010, some 18 years since its birth, surveys predict that 50% of U.S. farmers will have adopted some form of precision farming.

“Since 1992, the industry began in the data collection phase, and has evolved into the steering control and variable rate application. And now we’re entering the third phase, which is implement control,” Darr says.

“Precision farming has enhanced productivity, has put the operator back in control, has enabled precision placement, provided cost savings and environmental benefits, has reduced production variability and much more,” he adds.

Favorite quotes. Darr talked of a few favorite quotes heard during University precision ag field days. 1. “Just being able to watch my planter is payback enough to own auto steer.” 2. “Precision guidance along with statewide RTK (CORS network) will finally make strip-till easier to adopt.”

While paybacks vary on given farms and operation styles, Darr outlines his views based on current research…

- Lightbar guidance: 300 acres/year for payback

- Universal auto steer on tractor: 400-500 acres/year

- Integrated auto steering: 900 acres/year

- Auto swath sprayer: 1,800 sprayed acres/year

- Site specific (variable rate) solutions: harder to put numbers on right now

In the future, Darr added that he sees success in real time nutrient control, and a greater push to biorenewables for energy–which will be delivered by precision tools.

Case IH and Ritchie Implement teamed up with University of Wisconsin-Platteville (UWP) to benefit agricultural students and their studies of precision agriculture.

“Access to new Case IH agriculture equipment will be a tremendous asset to Pioneer Farm – the precision farming solutions will greatly increase the productivity of our operations,” says Phil Wyse, director of Pioneer Farm. “But more so than that, this partnership advances the mission of Pioneer Farm – to enhance the agricultural education experience for students on campus and for agriculturists throughout the surrounding communities. That’s what we’re really excited about.”

Pioneer Farm, the university’s 430-acre working farm, boasts some of the best soil in southwest Wisconsin. The gently rolling fields, managed with conservation in mind, rotate between corn, oats and alfalfa, and those crops help support the farm’s dairy, beef and swine enterprises. A combination of new Case IH tractors, hay tools, skid steers, tillage implements, a planter and a combine, delivered in early 2010 and each year thereafter, will be used in the farm’s day-to-day operations. The equipment allows students and farm visitors to see the productivity-enhancing benefits of Case IH equipment in real-world applications.

“With the support of Ritchie’s and Case IH, the UWP Pioneer Farm is able to make use of cutting-edge farming technology,” Wyse adds. “We applaud Ritchie Implement and Case IH for this valuable partnership.”

“Students and university researchers will get to see, run, test and learn all about the newest innovations in production agriculture first-hand,” explains Ron Ritchie, president of Ritchie Implement Inc., a Case IH dealer with locations in Barneveld, Cobb and Darlington, Wis. “Our goal is not only to broaden ag students’ educational experience and better prepare them for their farming careers, but also to enhance educational opportunities for active producers locally, regionally and across the state. We’re excited to be part of that important effort.”

As part of the agreement, Case IH product specialists will be available to support classroom instruction and participate in student clinics and shared community activities such as University Field Days with hands-on field demonstrations.

Popular Science magazine did a nice job providing readers with a glimpse into the precision agriculture research that is needed to grow twice as much food by 2050. The writer talked about how this challenge is everyone’s problem, but scientists are hard at work fomenting a second green revolution.

Here are the research projects that the magazine chose:
1. Sahara Forest Project — Greenhouses using seawater and solar power to grow cash crops in the desert.
2. Soil sensors — Research at Iowa State University into wireless soil sensors that may help farmers use water, fertilizer and other inputs more efficiently.
3. Improved rice — Researchers hope to turn this staple crop into a super rice that grows faster in warmer and drier climates by transforming its photosynthesis process.
4. Replace fertilizer — Michigan State researchers attempt to replace/reduce commercial fertilizer use with microbes. They are currently field testing microbial cocktails (Bio-Soil Enhancers) that can simultaneously reduce the need for phosphorous and nitrogen, protect plants against pathogens and boost yields in virtually any type of crop.
5. HarvestChoice — The Gates Foundation is funding data compilation of Africa’s agricultural systems and land use to increase yields to feed the growing continent.
6. Satellite soil moisture — NASA and USDA are working to monitor soil moisture levels around the globe to hopefully improve crop forecasting.
7. Robot labor — The challenge of American specialty crop growers finding human labor is increasing difficult. Current research using robots with a variety of sensors will help machines scan for fungus, growth rate, soil moisture, humidity, light levels and more. But cost of such technology is the current challenge.
8. Rebuilding soil — Scientists hope to turn waste into a charcoal that, when applied to degraded unproductive soil, will attract microorganisms to help plants access nutrients, hold more water and lock in carbon. Companies are working on portable machines to produce biochar on-site.
9. Make supercrops — Research is bioenginering the African staple crop cassava root to turn it into the PowerBar of the vegetable world. They’re attempting to increase protein, add vitamins, increase shelf life, add virus resistance and eliminate cyanide-producing toxins in the root.

Speaking at the bi-annual precision agriculture InfoAg conference in Springfield, Ill., recently, Utah State Geospatial Extension Specialist Phil Rasmussen talked about the latest tools he uses in the field.

Rasmussen has worked with NASA on remote sensing projects, and 10 years ago began a geospatial training program for County Extension agents called “On Target.” In his talk he highlighted the best GPS handheld units, software he uses, some new tools coming and how these technologies are continually evolving and converging. Some of the products he mentioned include:
Archer system by Juniper Systems
StarPal software system
Spot Tracker unit

Encouraging all farmers, not just the technology adopters, to use precision fertilizer Best Management Practices (BMPs) was the theme of an opening session talk by Clyde Graham, VP of Strategy and Alliances with the Canadian Fertilizer Institute.

Speaking at the bi-annual precision agriculture InfoAg conference in Springfield, Ill., today, Graham cited the importance of a global 4Rs BMP effort with their US counterpart, The Fertilizer Institute, and global science-based organization the International Plant Nutrition Institute (IPNI).

As environmental issues mount and become more personal, the 4Rs—Right source, Right rate, Right time and Right place—can help farmers and the public understand how fertilizer can contribute to sustainability goals for agriculture.

Listen to Graham as he outlines the need to achieve social, economic and environmental goals, and make sure farmers measure their performance to demonstrate an ability to operate without undue regulation.

Maximizing economic return is the payoff sought by growers with any precision farming technology. And a new story in Southeast Farm Press talks about how the Precision Farming team at the University of Georgia is using soil texture to target nematodes.

With precision agriculture, we try to refine things in order to achieve the goal of maximizing returns,” says Richard Davis, USDA-ARS plant pathologist in Tifton, Ga. “And when we talk about precision agriculture in nematode management, what we really end up talking about is more effective targeting of nematode applications.”

Many of the things growers do for managing nematodes involve making applications over entire fields rather than specific parts of a field, says Davis.

As part of a large project funded in part by Cotton Inc. and the Georgia Cotton Commission, the Precision Farming Team at the University of Georgia has been evaluating a number of techniques for delineating areas within fields at high risk for nematodes.

The fact that root-knot nematodes prefer sandy areas has encouraged researchers to find ways to rapidly measure soil texture — either directly or indirectly — and one of the most promising techniques is to directly measure soil EC. Soil EC is a function of soil texture and soil moisture. Sandy soils produce low soil EC while heavier soils result in higher values of soil EC.

While different instruments have been developed to measure soil EC, one of the most popular is the Veris 3100. This instrument has six coulter-electrodes (disks) mounted on a toolbar. As the Veris is pulled through the field, one pair of disks transmits an electrical current into the soil while another pair of disks measures the drop in voltage. The separation between the disks determines the depth to which soil EC can be measured. In the most commonly used configuration, soil EC is measured simultaneously from 0 to 1 foot (shallow) and 0 to 3 feet (deep).

In addition to directly measuring soil EC, there are other promising methods for indirectly measuring soil texture. These include using real time kinematic (RTK) GPS to rapidly create detailed topographic maps of fields. Elevation and slope of the terrain frequently dictate where coarse textured soil particles are deposited by erosion.

Ask any grower who is succeeding with the various tools of precision agriculture, and you’ll hear about the importance of the local dealer’s field technician–such as John Deere’s AMS Technician program.

For anyone interested in this growing job field, check out Oklahoma State University’s Institute of Technology, which offers a two-year Associate in Applied Science degree in Precision Agriculture Technology.

Graduates from the new program will be prepared for a higher level of agriculture, in which most new jobs require skills in GIS, GPS, and remote sensing in addition to the familiar disciplines of agronomy, plant science, and agri-business.

OSU Institute of Technology students will be learning to use GPS and GIS technologies to provide detailed information to farmers on their crop’s health status, irrigation and fertilizer need, plus warn of attacks by insects or weeds.

OSU Institute of Technology’s program is designed to meet the needs of two types of students: those who want to earn an associate’s degree in agriculture with high employment potential; or those who want to complete their first two years of an agriculture degree, then transfer to OSU’s Stillwater campus to earn their bachelor’s degree.
