spatial and temporal variations of crop fertilization and soil fertility in the loess plateau in china from the 1970s to the 2000s.increased fertilizer input in agricultural systems during the last few decades has resulted in large yield increases, but also in environmental problems. we used data from published papers and a soil testing and fertilization project in shaanxi province during the years 2005 to 2009 to analyze chemical fertilizer inputs and yields of wheat (triticum aestivum l.) and maize (zea mays l.) on the farmers' level, and soil fertility change from the 1970s to the 2000s in the loess plateau in china. the ...201425380401
yield responses of wheat to mulching practices in dryland farming on the loess plateau.improving farming practices of soil and water conservation has profound effects on the yield of wheat (triticum aestivum l.) in dryland farming regions of the loess plateau in china. mulching has proven to be an effective practice to increase crop yield, and possibly contribute to replenishing groundwater. this evaluation study collected and analyzed the data of 1849 observations published in 38 papers using meta-analysis to investigate effects of the mulching practices on wheat yield in terms o ...201526020965
