Resumo: | Animal protein production is considered to have high polluting potential. Hence, considering that environmental licensing is individual, it is necessary to determine the housing capacity, taking into consideration the production of manure and nutrient demand in agricultural areas and the manure’s agronomic efficiency. Thus, the objective of this research was to survey the housing potential, the animal protein production, the energy production potential using biogas, as well as the capacity for expansion of swine production, based on the demand for biofertilizers in the Western region of Paraná, considering the demand for nutrients for both soybean and corn crops. A total of 5169 swine barges and 6815 poultry sheds were mapped. The region has a strong potential for energy generation using biogas, with Toledo being the city with the largest number of pig and poultry sheds. By estimating the phosphorus demand of soybean (3.17 t/ha) and corn (5.92 t/ha) yields, it was found that Ubiratã is the city with the highest expansion capacity. It has been shown that for conditions of high soil phosphorus availability there are areas with low expansion capacity for pig housing. |
