36. Estimativa da capacidade de armazenamento de água no solo do Brasil. / Estimating of the soil moisture in Brazil
Soil moisture is a key variable in soil-atmosphere transfer processes. Soil moisture can be measured by direct and indirect techniques. Those methods are time consuming and impractical over large areas, such as Brazil. For this reason, soil moisture is generally estimated from the amount of water entering or draining from the soil profile by the water balanc
