O Uso de resíduos suinícolas em áreas de pastagens degradadas do Mato Grosso do Sul

Abstract

The Mato Grosso do Sul State is the 6th in the national pig production ranking. The most of swine production development came from the integration production system, generating more efficiency of activity in rural properties. The swine farming is a relevant activity but is a chain with great potential for environmental impacts, so producers are increasingly seeking to invest in measures to reduce the environmental of the sector. Pig production generates pollution for both water, soil and air, but can be mitigated with correct measures. This study aimed to analyze if the agricultural areas occupied by cultivated pasture in Mato Grosso do Sul support the amount of biofertilizer produced from treatments with biological reactors of swine manure from the same state. This study related the density of swine herds per hectare of pasture cultivated in degraded state in Mato Grosso do Sul State from the volume of housed active matrices. The data came from a yearbook produced by Agriness® from annual reports. Proportion calculations were performed and then the analyzes were performed using the Comparative Method. Furthermore, the cost-benefit ratio (RCB) was calculated based on the overlap of the actual cost of the conventional product over the benefit of substitution. In the Mato Grosso do Sul state the bulk of biofertilizer produced daily over the pasture produced is in a type state of degradation and the bulk of manure produced represents 0.16% of the required. For the cost-benefit measured from the indicated biofertilizer bulk (190 m³ / ha) was 0.13.
