Abstract
Comprehensive Nutrient Management Planning
‘Tools’ for growing season nitrogen management. The pre-sidedress nitrate test, the chlorophyll meter, and the corn stalk nitrate test are three ‘tools’ that are available to farmers and their advisors to improve nitrogen management, both environmentally and economically. To help participants in the 2001 CNMP program become familiar with these tests, we helped them conduct these tests on their manured fields. Most of the manure had been applied without calibrating the spreader or testing the manure.
