Abstract:

The objective of this work was to determine the soil moisture corresponding to the permanent wilting point (PWP) of soybean in two situations of soil, Rhodic Ferralsols with and without incorporation of biodegradable organic waste, justified for environmentally sustainable incorporation and also the determination of the physiological conditions of the crop in relation to the behavior of moisture. The experiment was conducted at the State University of Maringá, located in the city of Umuarama, PR, Brazil. The soils were placed in pots with two moisture levels, around 80% field capacity and in the field capacity. The determination of the permanent wilting point was performed following the method of determining physiological field. At this point, a sample of soil was collected (without roots) to determine the water content by gravimetric method. The physiological parameters were assessed using IRGA (Infrared Gas Analyze). The humidity of the permanent wilting point of soybean for regular Rhodic Ferralsols and incorporated Rhodic Ferralsols was 0.039 and 0.044 m³ m^-3, respectively. There was significant variation in the permanent wilting point in the 0-5 cm in the soil profile in relation to 15-20 cm. The intrinsic efficiency of the use of water for Rhodic Ferralsols in less than to the Rhodic Ferralsols incorporated with the biodegradable organic waste.
