Nitrogen (N) source more used is urea but it has serious problems with high nitrogen losses by ammonia volatilization. It is intensified in no-tillage system and in cane harvested green. Brazil is one of the producing greaters of maize. The cultivation of these crops occurs predominantly in tillage systems that retain the chaff on the soil because of many benefits to practical conservatio…
Brazil is a major producer of corn, and although the many benefits related to conservation practices and soil fertility in tropical climate provided by no-tillage system is known that the maintenance of the layer of straw on the soil surface is directly related to the loss of N-NH3 top-dressing, especially when using urea as nitrogen source. Urea is the most widely used nitrogen source, b…
The harvest of sugar cane, no straw removal by burning, is growing in Brazil. In this culture system, there are many questions about the management of stubble, and the quantities of nitrogen and potassium to be used. The various stubble management practices for conservation system can result in increased productivity, in addition, it is believed, it is possible to reduce the long term, ni…
