- Abstract
The cultural practice of covering the soil can bring benefits to the family farmer as the maintenance of soil moisture and the minimization of nutrient losses by leaching, reducing the need for fertigation. The objective of this work was to evaluate the moisture distribution and electrical conductivity of soil cultivated with BRS Princesa banana tree under fertirrigation and the use of mulch in the soil. The banana tree was planted at 2,5 x 2,0 m spacing and irrigated every two days by micro-sprinkler with a 60 L h-1 flow emitter for every four plants. The treatments were consisted in the absence and presence of dead cover of banana in the soil surface, with variation of the time, before and after the fertirrigation, and in the depths of 0,0 - 0,20; 0,20-0,40 and 0,40-0,60 m and distances 0,0-0,5; 0,5-1,0 m. The variables evaluated were the distribution of water and the electrical conductivity of the soil, with the distribution coefficients (CUD) and the Christiansen coefficient (CUC) being the indicators used to evaluate the distribution uniformity. Christiansen's Uniformity Coefficient (CUC) and Electrical Conductivity Distribution (CUD) decreased as a function of depth after fertigation and mulch did not influence the electrical conductivity distribution.
