A integração lavoura pecuária melhora a produtividade da terra?

Abstract

The present study aimed to evaluate the effects of a well-designed crop-livestock integration system, with inverted fertilization, comparing it with the producers’ traditional agricultural system. The justification was based on the idea that many producers, in leased areas, neglect fertilizing the winter crop, arguing that it will not bring any benefit to the subsequent crop. The experiment was conducted at the Mate Pronto Farm, in Saltinho - SC, between May 2024 and March 2025, with two treatments: SIPA, with inverted fertilization (sum of the recommendations for soybeans and oats), improved forage and zero fallow, and the Traditional, with fertilization only on soybeans (only the soybean recommendation), common forage and early desiccation. Forage production and animal production for the winter crop were measured; and final stand, number of pods per plant, grains per pod, thousand-grain mass and productivity for the summer crop. The results show that the SIPA produced more forage and had greater pasture support capacity. Since the SIPA treatment did not differ from the Traditional treatment in soybean grain yield, it was concluded that the inversion of fertilization does not compromise crop productivity. It is concluded that adopting SIPA fertilization systems is an efficient alternative in terms of production and sustainability, since it intensifies production in the winter without harming the soybean crop, contributing to the economic stability of rural properties.
