However, the lower yield often associated with corn (Zea mays L.) grown without tillage on the claypan soils of the eastern Great Plains may encourage alternative conservation tillage systems and management options. The objective of this study was to determine optimum seeding rates and fertilizer ...
According to the invention, N and P are regulated through the NAM additive, fertilizer can be applied for only one time and nutrient needs of a whole corn growing season can be ensured. The nutrient proportion of the fertilizer is relatively suitable for growing needs of the corn, thereby ...
这种更加密集的农业生产为增长的人口提供食物,而人口为土地提供更多的劳动力和肥料。 2.Grass played the pivotal role in the region's farm ecology: the grass fed cattle that, in turn, produced manure that was spread over the fields asfertilizerfor growing corn and other crops. (阅读 Z托福-11)您...
Nitrogen (N) applied in bands across cornfields often induces differences in plant height, leaf color, and growth stage of corn (Zea mays L.). Especially during wet springs, plants growing immediately over the bands are often noticeably taller and greener for a short period. Plants growing betw...

On average, over the 2 years, sugarbeet took up 95% more soil N than corn. These data indicate that fertilizer use efficiency may be improved by growing corn when residual N is lowest and tomato or sugarbeet when residual N is highest. With care to avoid residual N too high for ...
Base fertilizer: fertilizer applied for the first time before sowing or transplanting, or in every growing season of perennial fruit trees. Fertilizers for later absorption of crops. Seed fertilizer: when sowing or transplanting, fertilizer is applied near seeds or mixed with seeds to supply nutrient...
Determination of a crop’s nutrient needs is an essential aspect of fertilizertechnology. The appearance of a growing crop may indicate a need for fertilizer, though in some plants the need for more or different nutrients may not be easily observable. If such a problem exists, its nature must...
For instance, legislative measures in northern European countries have forced the greenhouse industry to convert all of its growing operations to closed production systems that eliminate nutrient leaching and runoff. This has resulted in the development of nutrient-recirculating technologies and management ...
