Sustainability, Environmental monitoring, Soil managementAbstract
The growing concern about accelerated soil deterioration has led to the need to develop tools that promote agricultural production, based on ambitious concepts. Although the definitions of sustainability and soil quality encompass political, social, economic and environmental issues, many scientific studies address soil quality, but only a few seek to quantify visual indicators of sustainable development, especially in agrarian reform settlements. However, these studies that present simple and easily measured alternatives are indispensable for decision-making and monitoring of agricultural systems. Therefore, the objective of this work was to evaluate soil quality through visual indicators in the Marcelo Déda Settlement Project, located in the municipality of Malhador, Sergipe. For this, 4 significant agricultural crops (Acerola, Macaxeira, Yellow passion fruit and pasture) and an area of native forest of the settlement reserve were chosen. The visual indicators selected are linked to the physical-hydraulic, chemical and biological parameters of the soil, being assigned values (1, 5 and 10) according to the visual degree of impact of the management in these indicators, which were classified in a participatory way with the farmers and researchers. The results allowed to classify the soil of the native forest as desirable in comparison to the land uses in the agricultural production systems studied in the Marcelo Déda Settlement Project, and the areas with the use of aceroleira presented more impacted visual indicators, thus indicating the need for essential changes in the management of the crop.
