Quantifying and understanding plant nitrogen uptake for systems modeling

A subject of numerous experimental studies over the past decade, plant nitrogen uptake is an important process in agricultural production and environmentalquality. However, there is still a limited understanding of its complex interactions with other soil-plant conditions. This book quantitatively examines plant nitrogen uptake, paying close attention to its interaction with other processes in agricultural systems, such as soil condition and plant growth. International contributors offer their perspectives, discussing commonalities and dissimilarities in simulating plant nitrogen uptake among various agricultural system models. The text also includes a CD with additional material. INDICE: Simulation of Plant N Uptake in Watershed Management. Modelling Water and N Uptake and Responses in Models of Wheat, Potatoes, and Maize.
