Abstract
A pot experiment was carried out using corn plants (Zea mays L.), in order to define the possible utilization of the concentrated pig slurry as an organic fertilizer, avoiding soil pollution caused by its chemical composition. Results obtained showed that on a slightly loamy coarse sand soil an amount of 40 t ha−1 on fresh weight basis of concentrated pig slurry can eventually substitute mineral nitrogen and phosphate fertilization at planting. The effects of increasing amounts of this organic fertilizer on soil characteristics and corn fodder composition were also investigated.
