Short-term CO2-C emissions from soil prior to sugarcane (Saccharum spp.) replanting in southern Brazil
New management strategies should be identified to increase the potential of bioenergy crops to minimize climate change. This study quantified the impact of sugarcane (Saccharum spp.) harvest systems, straw and soil management ...
Comparison Between Ground Ant (Hymenoptera: Formicidae) Communities Foraging in the Straw Mulch of Sugarcane Crops and in the Leaf Litter of Neighboring Forests
(Oxford Univ Press Inc, 2017-02-01)
In many sugarcane plantations in Brazil, the straw is left on the soil after harvesting, and vinasse, a by- product of the production of sugar and ethanol, is used for fertigation. Our goal was to compare ant community ...
Effect of potassium on nutritional status and productivity of peanuts in succession with sugarcane
(Soc Chilena Ciencia Suelo, 2015-01-01)
Potassium contained in sugarcane straw quickly returns to the soil in a form readily available to crops. Thus, the objective of this study was to evaluate the effect of potassium on the nutritional status and grain yield ...
Short-term effects of crop rotations on soil chemical properties under no-tillage condition
The use of crop rotation can provide sustainability for an agricultural production system by improving soil fertility and increasing nutrient use efficiency. Short-term changes in soil chemical properties were studied for ...
Rice straw ash: A potential pozzolanic supplementary material for cementing systems
(Elsevier B.V., 2017-09-01)
Biomass waste from rice straw has many management problems, including field firing causing severe air pollution and natural organic decomposition resulting in methane emission. The conversion of this waste to ashes may ...
Influence of inorganic additives on wheat straw composting: Characterization and structural composition of organic matter derived from the process
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2020)
Dinâmica de herbicidas em palha de cana-de-açúcar
The process of mechanical harvesting of sugarcane generates a large deposition of straw on the soil surface, providing a coverage that several studies have found important for reducing the weed population. Although such ...
Persistência e liberação de macronutrientes e silício da fitomassa de crotalária em função da fragmentação
(Universidade Federal de Uberlândia (UFU), 2012-05-01)
The persistence of straw, as well as the dynamics of nutrients release of it, are important aspects to consider in the choice of plants for composition of crop rotations in a no tillage system. Thus, the objective of this ...
