PROFITABILITY OF VARIABLE RATE PHOSPHORUS IN A TWO CROP ROTATION AgEcon
Popp, Jennie S. Hughes; Griffin, Terry W..
In the Midwest, the adoption of precision farming technologies began in the early 1990s. Research has produced profiles of early adopters, evaluated adoption trends and has identified factors that influence the adoption and profitability of precision farming. Importantly, this information is available to producers, who are interested in precision farming issues. In addition, the Midwest regional agricultural industry, strong promoters of precision farming technologies, has gained the confidence of farmers who now rely on them heavily for information on farming technologies. Precision farming in Arkansas, however, is still in its infancy. Adoption levels lag far behind those in the Midwest. Two reasons for this lag have been offered. First, some...

ADOPTION, PROFITABILITY, AND MAKING BETTER USE OF PRECISION FARMING DATA AgEcon
Lambert, Dayton M.; Lowenberg-DeBoer, James; Griffin, Terry W.; Peone, J.; Payne, Tim; Daberkow, Stan G..
Precision agriculture (PA) technology has been on the market for over ten years. Global Positioning Systems (GPS), Geographic Information Systems (GIS), yield monitors, variable rate technologies (VRT) and other spatial management technologies are being used by farmers worldwide, but questions remain about the profitability of the technology and its future. This paper summarizes: 1) data on adoption of PA technology worldwide, 2) review of PA economics studies and 3) efforts to make better use of yield monitor and other sensor data in crop management. The adoption estimates are based on reports by an international network of collaborators. This paper draws on USDA ARMS data to update U.S. PA adoption numbers. The PA profitability summary goes beyond...

Spatial Analysis of Precision Agriculture Data: Role for Extension AgEcon
Griffin, Terry W.; Lowenberg-DeBoer, James.
The role of Extension in assisting farmers conducting on-farm trials with yield monitors was assessed by direct casual observation and a formal interview during a three-year case study. Results indicate that Extension has a role in assisting farmers when selecting treatments to test, designing experiments, and interpreting statistical results.

ANALYSIS OF GOVERNMENT FARM SUBSIDIES ON FARMLAND CASH RENTAL RATES USING A FIXED EFFECT SPATIAL DISTRIBUTED LAG MODEL AND A TRANSLOG COST MODEL AgEcon
Lambert, Dayton M.; Griffin, Terry W..
The objective of this study is to examine how factors such as government payments, soil productivity ratings, commodity selling price, corn and soybean production, and spatial attributes affect cash rental rates. Baseline estimates of the effects of government payments on cash rents are determined using a fixed effect, distributed lag model. The results of this model are compared to a distributed lag model that incorporates spatial effects. A second model estimates the impact of government subsides on farm cost structure. This is accomplished estimating a fixed effect, translog cost function that also incorporates spatial effects. The data used in the analysis is the Illinois Farm Business Farm Management (FBFM) Economic Management Analysis (EMA),...

Conveying the Role of Professional Farm Managers to Potential Clientele AgEcon
Griffin, Terry W.; Baird, George E..
Many farmland owners opt to work directly with farmer-tenants while others choose to hire a professional farm manager to assist in the management of their land. As absentee landownership increases and more landowners become less associated with farming, professional farm managers have increased opportunity to communicate their role to potential clientele. Some landowners have an opportunity to make the most of their situation by enlisting the services of a professional farm manager, but only if they know what can be expected from a professional farm manager. We discuss some of the benefits and disadvantages to landowners and tenants of professional farm management and how professional farm managers can convey these ideas to potential clients and assist...

Field-Scale Experimental Designs and Spatial Econometric Methods for Precision Farming: Strip-Trial Designs for Rice Production Decision Making AgEcon
Griffin, Terry W.; Florax, Raymond J.G.M.; Lowenberg-DeBoer, James.
Site-specific data is spatially variable, precluding traditional econometric analysis. Some field-scale experimental designs present logistical, operational and mathematical problems in estimating treatment differences, specifically when adjacent observations are of different treatments such as with strip-trial designs. A modified spatial interaction structure is presented to analyze strip-trial designs with spatial econometrics.
