Quantification of the least limiting water range in an oxisol using two methodological strategies

Abstract: RESUMOO intervalo hídrico ótimo (IHO) tem sido utilizado como indicador de qualidade física do solo por representar em um único parâmetro as propriedades físicas diretamente ligadas com o crescimento de plantas, exceto a temperatura. O procedimento usual para obter o IHO envolve a determinação, em amostras com estrutura preservada e em laboratório, da curva de retenção de água (CRA) e da curva de resistência do solo à penetração (CRS). A determinação da CRA e CRS utilizando medições realizadas no campo (in sit… Show more

“…Columns were arranged vertically on a 10 cm high support structure, closed at the bases with aluminum screens (18 mesh) and plastic plates to avoid soil losses. Soil deposition was performed in the columns gradually, taking into account the soil density of the region (Moreira et al, 2014) to represent the same sequential order of the profiles in the ambient condition of the initial soil layers, until completing the height of 0.8 m. Columns was prepared in triplicate for each treatment: soil that received raw vinasse (SRV) and soil that received digested vinasse (SDV). The application of RV and DV was carried out manually.…”
