TL;DR: In this paper, the authors summarize published works for potential impacts of wide-scale, corn stover collection on corn production capacity in Corn Belt soils and conclude that within limits, corn Stover can be harvested for ethanol production to provide a renewable, domestic source of energy that reduces greenhouse gases.

TL;DR: Science-based policy is essential for guiding an environmentally sustainable approach to cellulosic biofuels and it is important to have a strategy that acknowledges the role of science in promoting sustainability.

TL;DR: Moran et al. as discussed by the authors used remotely sensed imagery to compare differ- crop management methods is difficult and expensive ent vegetation indices as a means of assessing canopy variation and where available, remotely sensed images its resultant impact on corn (Zea mays L.) grain yield.

TL;DR: In this paper, a portable chlorophyll meter was used to measure chlorophyLL content of leaves by means of transmittance measurements, and the relationship between chlorophyl content and crop N status was investigated.

TL;DR: Use of modified growing degree days, rather than days, as the divisor in these growth functions led to the recognition of physiological differences due to or associated with treatment, which were previously masked by normal crop response to temperature, and clarified other treatment differences by reducing the effect of temperature.
