Terry Griffin

Farm Management, Cropping Systems, Precision Agriculture

Assistant Professor 
Kansas State University

Terry Griffin’s research and extension programs focus on cropping systems economics in general, and specifically precision agricultural technologies and big data. Precision ag data in a community has evolved Terry’s program to include ‘big data’ specifically the automation of economic decision making tools. Current projects include farm management decision making under weather uncertainty, profitable automated variable rate irrigation applications, valuation of precision agriculture data, and farmland values.

Estimating Farmland Value

K-State agricultural economist Terry Griffin talks about a new tool that he has developed for estimating farmland value for a given year using the current value of that land...using annual value indexes for every year since 1950, the user can determine the tax liability of farmland transactions.

Calculating Farm Machinery Costs

K-State agricultural economist Gregg Ibendahl and Terry Griffin talk about a new online tool that farmers can use to calculate farm machinery costs...as input for making machinery purchase decisions, as a basis for comparing lease vs. purchase options, or for weighing the choice of custom hiring an operation instead of investing in equipment...they say it's an easy-to-use tool that can provide very useful information.

Least-Cost Fertilizer Options

K-State agricultural economists Terry Griffin and Gregg Ibendahl talk about a different approach to determining least-cost crop fertilizer options for producers, using an economic tool that they've developed that's now available to crop growers and retail fertilizer vendors alike.

Variable-Rate Fertilizer Applications

K-State precision agriculture economist Terry Griffin is joined by a gerontologist from the Arkansas Colleges of Health Education, LaVona Traywick. They cooperated on a recent study of variable-rate fertilizer applications, and why farmers have been slow to adopt that technology over the many years that it's been around. There are both economic and generational components to their findings, and this research says a great deal about how the different farming generations embrace precision technology.

Making Better Cover Crop Choices

K-State cropping systems economist Terry Griffin talks about his current project, developing a tool for producers to use in optimizing their cover crop selection, making decisions on a least-cost basis...he goes over the variables that producers need to think about when putting together an economical cover crop mix that still serves the intended purposes.

Ag Technology and Farm Labor

From the recent Women Managing the Farm Conference at K-State, agricultural technology specialist Terry Griffin shares some observations from a discussion forum he moderated, on farm technology adoption and how that impacts farm labor. Terry also hints at an emerging conflict between two major farm data services. Could this conflict get the attention of legislators?

Big Farm Data

K-State precision agriculture economist Terry Griffin looks at the ongoing issue of "big farm data":  who owns it, and to what extent do farmers want to commit to a data processing venture...he tackled those and other questions as an invited speaker at an ag data law symposium hosted by Texas A&M University last week.

Autonomous Farming Systems

K-State ​precision agriculture economist Terry Griffin talks about the economic feasibility of autonomous farming systems, which have become the premiere topic at several precision agricultural technology conferences he has participated in this winter...he also touches upon the ongoing issue of how best to utilize and manage precision data collected at the farm level.

Trends in Farm Management Research

K-State agricultural economist Terry Griffin talks about a different kind of analysis he has just finished up:  he tallied articles from a highly-respected journal to identify trends in farm management research, which indicated to him where such research might best be directed going forward.
