Objetivou-se, com esse trabalho, avaliar a taxa de decomposição e a velocidade de liberação de macronutrientes e Si da fitomassa do consórcio crotalária mais milheto, em função do tempo após manejo, sem e com fragmentação. ...

Crops used to cover the ground may also release nitrogen into the soil during mineralization. However, it is necessary to identify species that combine fast nutrient release and longer permanence of the straw on the soil ...

The objective of this work was to evaluate the rate of decomposition and rate of release of macronutrients and Si in the biomass from intercropped sunn hemp and millet, as a function of time after management, both with and ...

The objective of this work was to evaluate the effects of silicon application adjusted with nitrogen fertilization via top-dressing on grain productivity, the silicon contents of the soil, in the plant tissue and nitrogen ...

The use of sprinkler-irrigation and/or high levels of fertilization in upland rice can increase plant height and hence plant lodging. Lodging can be controlled by using growth regulators, in order to reduce plant height. ...

The cultivation of upland rice seems to be, among the major crops, the least adapted to the notillage system (NTS). One of the reasons attributed to this lower adaptation to NTS would be the low activity of the nitrate ...
