Assessing the Effects of Conservation Practices and Fertilizer Application Methods on Nitrogen and Phosphorus Loss from Farm Fields – A Meta Analysis

IPNI-2014-USA-4RM07

Summary We propose a meta-analysis of the effects of water and soil conservation practices, as well as the effects of fertilizer application methods, in reducing nutrient loss from farm fields. An preliminary analysis of an existing database showed that the difficulty of a successful meta-analysis lies in how to properly handle confounding factors because studies of agriculture practices are carried out under different conditions (e. g. , crops, tillage methods, and climate).
