Semeadura direta como técnica de restauração ecológica para o cerrado sensu stricto no assentamento Teijin em Nova Andradina-MS

Abstract

The Cerrado, the second-largest biome in Brazil, covering more than 200 million hectares, is rich in biodiversity but faces fragmentation and degradation. The ecological restoration of degraded areas is crucial, and direct seeding stands out as an effective and low-cost technique. This methodology involves depositing seeds directly into the soil, making it adaptable to various conditions. This study evaluated the development of native species sown in soils from dry and flooded areas, using different organic compounds in a 0.5-hectare Permanent Preservation Area (PPA) at Sítio Bom Jardim II, in the Teijin Settlement in Nova Andradina-MS. Seeds from nine species were collected, tested for viability, and properly stored before sowing. Compounds such as soil (the control), Baru husk (Dipteryx alata), charcoal dust, and a mixture of Baru husk (Dipteryx alata) with charcoal were added in four treatments in the areas as substrates for spring restoration. The research aimed to understand how these factors influence plant emergence and growth, contributing to the recovery of the Cerrado.
