Understanding the sources of grain N uptake (Grain N) in maize (Zea mays L.) and
especially the trade‐off between reproductive‐stage shoot N remobilization (Remobilized N) …

There is limited information on agronomic practices affecting wheat (Triticum aestivum L.)
yield in intensively managed dryland systems despite the opportunity to narrow the existing …

Generic, robust models are needed for estimating crop nutrient uptake requirements. We
quantified and modeled grain yield–nutrient uptake relations in maize grown without …

Understanding nutrient balances in changing cropping systems is critical to appropriately
adjust agronomic recommendations and inform breeding efforts to increase nutrient …

Intensive fertilizer usage of KCl has been inculcated as a prerequisite for maximizing crop
yield and quality, and relies on a soil test for exchangeable K in the plow layer to ensure that …

Global food production strongly depends on availability of nutrients. Assessment of future
global phosphorus (P) fertilizer demand in interaction with nitrogen (N) and potassium (K) …

The Role of Plant Roots in Crop Production presents the state of knowledge on
environmental factors in root growth and development and their effect on the improvement of …

As an essential element of crop growth, phosphorus (P) plays an important role in
maintaining agricultural sustainability and ecological balance. A quantitative understanding …

Reliable estimates of crop nitrogen (N) uptake and offtake are critical in estimating N
balances, N use efficiencies and potential losses to the environment. Calculation of crop N …

The widespread promotion of conservation agriculture (CA) in regions with weathered soils
prone to phosphorus (P) deficiency merits explicit consideration of its effect on P availability …
