Evaluating and improving corn nitrogen fertilizer recommendation tools across the U.S. Midwest
(University of Missouri--Columbia, 2018)
Determining which corn (Zea mays L.) nitrogen (N) recommendation tools best predict the economically optimal N rate (EONR) would be valuable for maximizing profits and minimizing environmental consequences. The objectives of this research were...
Integrating cover crops into crop rotations in upstate Missouri
(University of Missouri--Columbia, 2018)
"There is an increasing emphasis on management strategies such as reduced tillage, use of cover crops, and implementation of conservation practices (i.e. terraces, no-till, and cropping systems) in Missouri cropping systems. By combining best...
Soil characteristics and subsequent corn development following partial corn residue removal in a no-till, corn-soybean rotation
(University of Missouri--Columbia, 2013)
treatment increased soil ammonium-N concentration, soil water content at R1, minimum and average soil temperature at corn emergence (VE). Early, median and late emerging corn plants of each residue and cover crop treatment were also tracked throughout...
