Description
Book SynopsisDiscusses New Advancements to Improve Existing Simulations of Plant Nitrogen
Written by research pioneers and leading scientists in the area of agricultural systems, Quantifying and Understanding Plant Nitrogen Uptake for Systems Modeling comprehensively covers plant N uptake in agricultural system models, especially for building soil-plant system models.
The text illustrates how to minimize the transportation of nitrogen fertilizers in crop production to surface and ground waters, as even moderate errors in uptake estimations lead to a dramatic increase in the amount of nitrogen leached into groundwater. It also highlights the knowledge gaps preventing correct simulation of this process and explains what to look for when using a system model and interpreting simulation results.
Applies to a Variety of Crops, Including Oilseed, Wheat, Potatoes, and Maize
Trade Review
Ma et al have compiled tile latest developments in modeling plant nitrogen uptake. Through 13 chapters the contributing authors cover topics from the rhizosphere and roots to mycorrluzae and Michaelis-Menten kinetics. Each chapter is straight to the point and focuses on a different model and crop, which is useful as an introduction to each model as well as insightful into specific crop behaviour. A good overview of model structure is provided for each model, and most are tested against data...this should be the first source to go to for a solid overview of quantifying and understanding plant nitrogen uptake for systems modeling. --CAMBRIDGE JOURNALS, 2010
