The sugar and alcohol plants generate waste stillage one that needs proper destination. One alternative is the application of this residue to improve soil properties. The objective of this study was to evaluate the effect of stillage in the aggregation and productivity of sugar cane grown in three seasons of the soil sampling. The study was conducted in an Red dystrophic Latosol, sandy clay frank, at the BUNGE Monte Verde plant in the municipality of Ponta Porã, MS, Brasil. Cultivated with sugarcane third year. We used the (4 × 4) factorial design, evaluated 4 applications of stillage (0, 450, 600 and 750 m3 ha-1) and their soil characteristics measured at four depths (0,0-0,5; 0,5-0,10; 0,10-0,20; 0,20-0,40 m) with five repetitions. To determine the rate of dispersion of aggregates (ID) sample were obtained undisturbed soil at 38, 75 and 111 days after application of stillage. With increasing doses of stillage were increased concentrations of potassium and organic matter and reduce the rate of dispersion and increased stability of soil aggregates.

The objective of this work was to evaluate the agronomic behavior of the cilantro in organic no-tillage system under alive and dead mulching and fertilized with doses of compost. The experimental design was randomized blocks, in a split-plot arrangement with four replications. The plot corresponded to the planting system (no-tillage with live mulching of Arachis pintoi, with live mulching of native weed, with mulching of straw and conventional tillage). In each plot the splitplot were represented by the doses of organic compost 10; 20 e 30 t ha-1 of dry compost. The no-tillage system with straw and conventional tillage showed the best results in all variables in the plant compared with no-tillage systems with live mulching of peanut crop and native weed. Cilantro answered linearly to fertilization, with yields of 4,554 t ha-1 to 6,542 t ha-1 when fertilized with 10 to 30 t ha-1, respectively.
