Cattle ranching is a major agricultural activity in Central Brazil and it plays a major economic role in Mato Grosso do Sul State. In the last few years, local agricultural development has been influenced by other agro-industries, mainly sugar cane and eucalyptus forestry, expanding over grazing areas, causing herd displacements but alsoleading to changes on local production systems. Herd numbersshow a tendency to decrease, while beef production keeps stable.This means improvements on individual husbandry techniques as wellas a general re-arrangement of herd structure. This can have important consequences on greenhouse gases (GHG) emissions from the sector inthe area. In this context, the goal of this study was to explore the implications of changes on cattle herd size and structure as well as land use change on GHG emissions per unit beef produced per unit of area used for cattle grazing in Mato Grosso do Sul State. |

Purpose: Determine the decomposition of compost under two levels of shading (total and none) and central pivot and sprinkler irrigation. Methods: Litter boxes were made with a 4mm mesh base, and PVC sides and filled with compost. Boxes were recovered after 0, 2, 4, 6, 8, 10 and 12 months. Amounts of remaining compost and nutrients were measured and decomposition rates and half-life values were calculated. Soil under the litter boxes was analyzed before and after removing boxes, for nutrient contents (N, P, K, Ca, and Mg) and organic carbon. Results: Compost was lost quickly over time. Losses were faster under central pivot than sprinkler irrigation. Total shade caused higher rates of decomposition than without shade. Half-life values varied from 0.12 to 1.02 years. Losses of nutrients were substantial, with P and K being lost at faster rates than mass loss. Conclusions: Nutrients were lost rapidly from compost and were mostly not present in the soil. Insects may have removed compost from the boxes. Total shadowing increases decomposition rates of compost. |
