Research Project:
SITE SPECIFIC APPROACHES TO DEVELOP PRECISION AGRICULTURE TECHNOLOGY FOR USE ON COMMERCIAL FARMS (GUNNISON, MS)
Location: Genetics and Precision Agriculture Research
Project Number: 6406-21610-008-02
Project Type:
Nonfunded Cooperative Agreement
Start Date: Sep 29, 2006
End Date: Mar 31, 2009
Objective:
The objective of this cooperative research project is to: (1) determine if a topologically based general linear mixed model statistical approach is applicable for the analysis of the effects of site-specific and conventional management practices which occur at similar or different times and locations on commercial farms; (2) develop a cooperative project between a commercial farm and ARS research to determine if the proposed statistical/geographical information system (GIS) analysis process is applicable for commercial farms and if it can be formulated into a farmer/consultant friendly approach; and (3) determine the utility of applications of wireless technology to capture, share, and transfer spatial information about farm operations so that it strengthens the ability of farms to complete analyses of their farm operation.
Approach:
Work will be done in large commercial cotton fields on a cooperator farm. Define experimental units in a unique way so that independence among control and management treatments is achieved. The analysis process uses the spatial demographics modeled in the GIS to create zones of conventional agricultural practice within commercial production fields. Experimental precision agricultural practices are evaluated against conventional practices by use of smaller floating plots imbedded within the larger zones by spatially including the necessary information into a prescription file used by the VR controller. The various agricultural practices are evaluated using analysis of covariance to obtain regression effects describing the plot demographics. Using geospatial information the spatial correlation structure describing the relationships among plot residuals can be modeled. Wireless systems networks are developed to communicate commands and feedback information among personnel, computers, and field variable rate requipment.
