Thoroughly tested simulation models are needed to help quantify the long-term effects of agriculture. We evaluated the Root Zone Water Quality Model (RZWQM) response to different N management strategies and then used the tested model with observed weather data from 1961– 2003 to quantify long-term effects on corn (Zea mays L.) yield and flow weighted nitrate-N concentration in subsurface “tile” drainage water (Nconc). Fourteen years (1990–2003) of field data from 30, 0.4 ha plots in northeast… Expand

Soil-test N recommendations augmented with PEST-optimized RZWQM simulations.
TLDR
RZWQM is a promising tool to accurately estimate the water quality effects of LSNT; the majority of N loss difference between LSNT and fall applications is because more N remains in the root zone for crop uptake; and year-to-year LSNT-based N rate differences are mainly due to variation in early-season precipitation and temperature.

TLDR
The calibrated Root Zone Water Quality Model (RZWQM2) was used to assess crop yield and N leaching under current and alternative management practices in a double-cropped wheat and maize system under long-term weather conditions (1970-2009) for dominant soil types at 15 locations in the North China Plain.
