Pheasant Reproduction and Survival as Related to Agricultural Fertilizer Use

Associations between Schistosomiasis and the Use of Human Waste as an Agricultural Fertilizer in China

BACKGROUND Human waste is used as an agricultural fertilizer in China and elsewhere. Because the eggs of many helminth species can survive in environmental media, reuse of untreated or partially treated human waste, commonly called night soil, may promote transmission of human helminthiases. METHODOLOGY/PRINCIPAL FINDINGS We conducted an open cohort study in 36 villages to evaluate the associ...

Long-term fate of nitrate fertilizer in agricultural soils is not necessarily related to nitrate leaching from agricultural soils.

Accounting for the fate of inorganic N fertilizer in agricultural systems is critical to sustainable production. Sebilo et al. (1) provide a unique long-term record of NO3 fertilizer fate that demonstrates N molecules from a discrete fertilizer application are transferred to soil organic matter (SOM) and subsequently mineralized over the course of approximately 100 y, during which they contribu...

Urbanization and the Change of Fertilizer Use Intensity for Agricultural Production in Henan Province

China’s urbanization has resulted in significant changes in agricultural land use. However, understanding of the linkages between urbanization and fertilizer use intensity is limited. Using county-level panel data for Henan Province, 1995–2008 and panel econometric models, we investigate the impact of urbanization and other socioeconomic factors on fertilizer use intensity, with a focus on the ...
