Recovery of residual fertilizer-nitrogen by wheat in a winter wheat–summer maize rotation in the north china plain: A soil column study
Cropping systems is potentially useful practice for mitigating nitrate leaching and increasing nitrogen use efficiency (NUE) because deeper rooted crops could capture the leached N from previous shallower rooted crops. The recovery of fertilizer nitrogen (FN) applied to maize (Zea mays L.) by the succeeding wheat (Triticum aestivum L.) in a winter wheat–summer maize rotation in North China Plain ...

PRZM-3, A Model for Predicting Pesticide and Nitrogen Fate in the Crop Root and Unsaturated Soil Zones: Users Manual for Release 3.12.2
This publication contains documentation for the PRZM-3 model. PRZM-3 is the most recent version of a modeling system that links two subordinate models – PRZM and VADOFT – in order to predict pesticide transport and transformation down through the crop root and unsaturated soil zones. Enhancements to Release 3.0 reported herein include algorithms that also enable modeling of the nitrogen cycle ...

N-(N-butyl) Thiophosphoric Triamide Solution
N-Butylthiophosphoric triamide (NBPT, hereinafter referred to as "NBPT") is currently one of the most effective soil urease inhibitors. Agricultural fertilizers, mainly nitrogen fertilizers, are quickly decomposed by urease in the soil under normal use. This not only wastes a lot of nitrogen fertilizer resources, but also increases the cost of crop production, and brings a series of problems such ...

Reuse of Dairy Lagoon Wastewater Through SDI in Forage Crops
Abstract California has become the leading dairy products producing state in the USA. This has resulted in farms commonly milking several thousand cows per day. The care and feeding of the animals has produced large waste streams commonly collected and stored in lagoons. Environmentally safe handling and reuse of the lagooned wastewater is the objective of this study. A system of Subsurface Drip ...
