How Choice Of Soil Sampling Strategy Impacts Application Accuracy And Economic Of Site-Specific Nutrient Management In Cotton?

Presented by:  Dr. Simerjeet Virk, Assistant Professor and Extension Precision Ag Specialist, University of Georgia

Proper nutrient management is important to attain high-yielding cotton. Several soil sampling strategies including both traditional and precision methods –grid and zone –are commonly used by growers across the Cotton Belt to determine nutrient requirements prior to fertilization. With high fertilizer prices, it is important to utilize a soil sampling strategy that not only effectively depicts the actual nutrient spatial variability within a field but is also cost-effective. Information on how different precision soil sampling strategies, especially different grid sizes and zones based on different spatial layers, influence the application accuracy and economics of variable-rate fertilizer applications in cotton will be shared.

Ladder:  Large Agricultural Database That Drives Extension And Research

Presented by:  Zach Reynolds, Mississippi State University

Big data capture and analytics may be foundational to addressing a multitude of research and Extension areas in the Mid-South. Analysis of large-scale, agricultural data can be used to determine the effects of agronomic practices, management philosophies, and environment on crop productivity and profitability. Therefore, the LADDER program will collect, process, and securely store geospatially specific agronomic and environmental data for the purpose of addressing some of the Mid-South’s primary research and Extension concerns.
