Since the pioneering work of CT de Wit in the 1960s, the Wageningen group has built a
tradition in developing and applying crop models. Rather than focusing on a few models …

Crop simulation models have been used widely to describe systems and processes at the
level of the genotype, the crop, the farming system, the region, and the global environment …

Rice (Oryza sativa L.) yield increases in Zhejiang, China have slowed since 1985 despite
the increasing use of hybrids and fertilizers. On‐farm experiments at 21 sites were …

Attaining maximum economical yield is the priority of irrigated rice farmers. Current fertilizer
management practices in intensive, irrigated rice systems are, however, not tailored to the …

Precision farming is a systems approach to managing soils and crops to reduce decision
uncertainty through better understanding and management of spatial and temporal …

Environmental pollution by nitrogen (N) leaching or runoff from rice fields and high pesticide
use has become a serious concern in China. Average N application is high and fertilizer-N …

This book, based on work sponsored by the Natural Resources Systems Programme of the
UK Department for International Development, reviews progress in crop-soil simulation …

Mid-season nitrogen (N) application in rice crops can maximize yield and profitability. This
requires accurate and efficient methods of determining rice N uptake in order to prescribe …

This paper presents a water and nitrogen balance model for the surface ponded water and
soil profile system of rice (Oryza sativa L.) fields. The model estimates the daily water …
