Making Recommendations Based on Local Databases
Nitrogen Recommendations Based on Local Databases
Fertilizer N management practices were developed by an agronomist through a locally-based research program. The objective of the agronomist was to determine if and/or how generalized N recommendations needed to be changed to better fit local conditions. Years of collecting data on local management practices coupled with replicated research trials allowed him to determine economically optimum N rates for the predominant soil types in his trade area. This information provided him with the agronomic basis to use new technologies to vary N rates across the field according to soil type.
