Location: Grassland Soil and Water Research Laboratory
Project Number: 3098-13610-009-100-A
Project Type: Cooperative Agreement
Start Date: Jun 1, 2024
End Date: Dec 31, 2026
Objective:
To evaluate the development of in-field management zones for precision fertilizer application based on grid soil sampling or historic yield mapping data for profitability and feasibility in Maryland.
Approach:
We plan a two-stage evaluation of multiple methods for delineation of in-field management zones for future precision fertilizer applications. First, we will work with a private consultant to mine historic (>15 years) of yield monitor data and develop management zones based on these data and other field characteristics, including yield variability over time, particularly in a field where management zones have been developed based on grid soil sampling. We will model potential (or realized) profitability impacts through precision applications based on the hypothetical management zones.
In the second stage, we will execute an in-field evaluation where we will work with a participating farmer to develop zones and execute precision fertilizer application of their choosing, either through the use of their equipment or University-owned precision application equipment. We will evaluate profitability of precision application and discuss feasibility or willingness to adopt practices with the participating farmer to increase our understanding of implementation of precision technology by Maryland farmers.
