The objective of this work was to study the effect of grazing systems: rotational, continuous and the absence of cattle, in pastures of Brachiaria brizantha on microbial activity (respiratory, potential nitrification, solubilizing, and enzymatic) and on the chemical attributes (contents of organic carbon, total nitrogen, organic phosphorus, and moisture) of Eutrustox soil over one year. Eight Canchim breed animals were used. The samples were collected in the four seasons from 2005 to 2006. The average of organic C, organic P, […]

Sugarcane bagasse with 55% of dry matter (DM) was treated with five levels of urea (0, 2.5, 5, 7.5, and 10%) and 5% ground whole soybean as a source of urease both, on a DM basis. The material was stored in plastic bags for 97 days (8 kg/ 50 L plastic bag), and after plastic bag opening, samples were collected at three aeration period (2, 9, and 16 days). A completely randomized design with three replicates was used. There was […]
