Fertilizer quantities and frequency of application are determined by vine age, growth vigor, and nutrient requirement at different phenological stages, as well as by fruit yields. Given the conditions ofkiwifruitorchards in China, it is recommended that fertilizer be applied two or three times a yea...
In our experiment we tried to find out what kind of eventual changes in the environment and in plant chemical composition occurred in response to different fertilizer treatments applied to sweet corn (Zea mays convar. saccharata) grown on sandy soil with low humus content. The ploughed layer co...
Under different nitrogen application patterns, the yield of corn and the nitrogen fertilizer's efficiency were analyzed. The results indicated that the yield of N-fertilizer treatments were higher than no N-fertilizer in basal and dressing application. The yield by 150kg/hm2 urea application was th...
Green manure crops are usually planted in the fall and turned under in the spring before the summer crop is sown. Their value as a source of nitrogen, particularly that of the legumes, is unquestioned for certain crops such aspotatoes,cotton, andcorn(maize); for other crops, such aspeanuts...
The objective of this project was to measure corn yield response to fertilizer nitrogen (N) application timing (spring pre-plant or at-planting vs. split/side-dress) across multiple N rates (0 to 250 lb total-N/acre). Results were determined through fitting yield response to N-rate ...

We compute the fertilizer use in corn, cotton, soybeans, and rapeseed in the period from 1990 to 2010 for a set of selected countries. In each case, we present the consumption of nitrogen, phosphate, and potash by crop and by year, reporting both the fertilizer application rates (in kilog...
In the corn year, season-long cumulative soil CO(2) emission was greatest with the zero N application. There was no effect of N applied in the prior year on CO(2) emission in the soybean year, except at one of three sites, where greater applied N decreased CO(2) emission. Soil ...

Our GHG study builds upon previous work at the St-Emmanuel site, which focused on N leaching and corn N recovery, and therefore enlarges our collective understanding of N dynamics in subsurface-irrigated maize fields. As soil substrates are retained within the rhizosphere, SI improves the availabi...
