Atributos físicos de um latossolo amarelo sob cultivo de diferentes gramíneas na região dos tabuleiros costeiros da Bahia

Abstract

Soil physical quality plays a vital role in promoting sustainability, performing essential functions that impact root development, water and nutrient retention and quantity, gas exchange and biological activity. Grasses play an essential role in improving the physical characteristics of soil, making it more suitable for growing plants, absorbing water and promoting the health of ecosystems. Its root system, ability to protect against erosion and the addition of organic matter promote soil quality. The objective of this study was to evaluate the changes in the physical properties of a Yellow Oxisol under study from different species of grasses and native scenarios. The experiment was carried out in Cruz das Almas-BA, in an area already required with the following grass species: Capim-Elefante cv. Purple (Pennisetum purpureum Schum); Elephant Grass cv. BRS Capiaçú (Pennisetum purpureum Schum); BRS kurumi elephant grass; Elephant Grass cv. Napier (Pennisetum purpureum), Digitaria decumbens Stent cv. Transvala and Native Vegetation. The experimental model used is a completely randomized design (DIC) where the following soil physical parameters are being evaluated: soil texture; soil and particle density; total porosity; macroporosity and microporosity; liquidity limit; plasticity; infiltration speed and resistance to penetration at depths of 0 - 0.10 m; 0.10-0.20 m and 0.20-0.40 m. The collected data were subjected to analysis of variance and compared using the Tukey test at 5% significance. Grasses represent a viable and economical option for biological soil decompression, improving some physical properties of the soil.
