QUALIDADE DO SOLO EM SISTEMA DE INTEGRAÇÃO LAVOURA-PECUÁRIA-FLORESTA

Abstract

The growth in demand for food led to an increase in the conversion of native areas to agriculture and pasture. Thus, the exploitation of natural resources and changes in land use caused loss of biodiversity and soil degradation, harming agricultural activity. Therefore, the objective of this work is to describe the characteristics of the integrated farming and livestock forest system (ILPF), and to demonstrate the importance of this system for the improvement of soil properties, evidencing the efficiency of the ILPF in soil attributes. This work is a bibliographical, qualitative and exploratory review about the ILPF system, and its benefits for soil attributes and the environment. A bibliographic survey was carried out in scientific articles, books, dissertations and theses based on Google Scholar and Scielo. The ILPF consists of the combination of trees, agricultural crops and animal husbandry, simultaneously or in sequence. Due to its characteristics of increasing production without converting new areas, ILPF is considered good for the sustainable expansion of agribusiness in Brazil. ILPF improves fertility, biomass accumulation, and soil chemical and physical variables, increasing the levels of organic matter, calcium, magnesium and phosphorus. The ILPF is part of the ABC Plan (Low Carbon Agriculture Program), however there are still obstacles in the adoption of this system by farmers. It is necessary to carry out studies on the implantation and choice of species, ensuring greater efficiency and productivity, in addition to improvements in soil quality.
