Book Description
Depth to claypan (DTC) plays an important role for Midwest claypan soils in storing plant-available water for grain crops, but it is unknown how this same soil property affects switchgrass (Panicum virgatum. L.) growth and nitrogen (N) utilization. This research assessed corn (Zea mays L), soybean (Glycine max. L. Merr.) and switchgrass productivity as influenced by the DTC. Plot research was initiated in 2009 in Columbia, Missouri on a range of DTC. Canopy reflectance sensing early in the growing season was effective at estimating yield (p=
