- Abstract
Intensive pig farming concentrates a great number of animals per area generating high volume of wastewater, which requires correct disposal since it might cause environmental imbalance. Pig farming wastewater (PFW) can be used as fertilizer due to its characteristics. This study aimed to evaluate the effect of applying pig farming wastewater on chemical properties of Dystric Nitosol and on elephant grass (Pennistum purpureum Schum) production. An experiment was carried out in field conditions consisted of five treatments plus control. T0 = without PFW application (control), T1 = 150 m3 ha-1, T2 = 300 m3 ha-1, T3 = 450 m3 ha-1, T4 = 600 m3 ha-1, T5 = 750 m3 ha-1 PFW applied during elephant grass crop cycle. P, K+, Mg+2, Ca+2 concentrations were obtained in the soil before and after PFW application. Phosphorus concentration in the soil increased as a function of PFW application rates increase. Al+3 concentration decreased. PFW application did not influence plant height and dry mass production of the grass.
