Harvesting Systems, Soil Cultivation, and Nitrogen Rate Associated with Sugarcane Yield
(2018-09-01)
The adoption of mechanical harvesting of green cane gives rise to concerns as to whether systems developed under burnt cane harvesting are applicable to a green cane harvesting system. In particular, tillage, which is an ...
Effect of tropical grass and nitrogen fertilization on nitrous oxide, methane, and ammonia emissions of maize-based rotation systems
(Elsevier B.V., 2020-08-01)
While tropical grasses were shown to inhibit the activity of soil nitrifiers, their role in greenhouse gas (GHG) and ammonia (NH3) emissions in N fertilized maize-based rotations are poorly understood. A 3-year (2014-2017) ...
Fertilization of high-yield corn with poultry litter based on nitrogen doses
(Empresa Brasil Pesq Agropec, 2018-03-01)
The objective of this work was to recommend nitrogen doses from poultry litter-based organic fertilizers in powder and pellet forms, compared with mineral fertilizer, in a high-yield corn crop under notillage. The treatments ...
RESPONSE OF A FOURTH RATOON SUGARCANE CROP TO NITROGEN, SILICON, AND LIME FERTILIZATION
(Colegio De Postgraduados, 2015-07-01)
Maximum efficiency of nitrogen (N) is attained when fertilizer is accompanied by silicon (Si). Therefore, the objective of this study was to evaluate the chemical attributes of the soil, the nutritional status, the yield ...
