Developing Multi-Variate Management Zones for Corn Production

This project intends to evaluate the benefit of multi-variate management zones and develop strategies which can account for the temporal and spacial variability seen in crop nutrient requirements.

Into/justification As agricultural technologies advance the amount of information collected per acre in increasing at a rapid pace. Many are looking towards methods to take advantage of this data and make management decision. Currently many of these decisions made based upon assumptions and theory’s and most focus at a one dimensional resolution. Read more

Interpretive Summary

2016

The objective of this project is to evaluate the benefit of multi-variate management zones and to develop strategies that can account for the temporal and spatial variability seen in crop nutrient requirements. During 2016, grid soil sample data were collected from 300 fields. Location of these fields stretched from central Kansas to Southern Oklahoma. The data set included records from 22 counties in Oklahoma and four counties in Kansas.

2015

The objective of this project is to evaluate the benefit of multi-variate management zones and to develop strategies that can account for the temporal and spacial variability seen in crop nutrient requirements. Two fields were identified in North Central Oklahoma; a 61-acre rainfed field and an 88-acre irrigated field. The two locations were chosen due to their history of high yields and likelihood of nutrient variability.
