“…Desta forma o solo funcionaria como um reservatório de água para as plantas, mesmo estando aberto para a atmosfera e para os horizontes mais profundos do perfil. Para fins práticos, este conceito é válido desde que não seja universalizado para todos os tipos de solo (AGUIAR NETTO; NACIF; REZENDE, 1999;REICHARDT, 1988), uma vez que a determinação da CC torna-se subjetiva diante do fato de que o processo de redistribuição da água no solo é contínuo, sem apresentar interrupções abruptas ou níveis estáticos (REICHARDT, 1975).…”

World agriculture will face the challenge of guaranteeing the food security of 9 billion people in the 2050s. Given this, it is essential to develop new farming techniques aimed at increasing food production and also the sustainable maintenance of natural resources and the environment. To produce food in the right quantity, at the right time, and affordable prices, farmers must adopt precision farming models to increase the food production amount. Precision agriculture uses agricultural management techniques based on the measurement and control of crop parameters such as soil moisture, air temperature, and the irrigation control. In this context, agricultural irrigation accounts for the greater consumption of freshwater available for use on the planet. Adopting techniques that allow increasing agricultural production, reducing irrigated water amount and waste, becomes crucial and the most appropriate responses are the implementation of solutions using Artificial Intelligence. This work uses a Precision Irrigation model, with the rain forecast as a complement to the irrigation process, to keep the soil moisture at an appropriate level for the sweet pepper culture. A fuzzy inference system was used in the the irrigation prescription amount, with the climatic data acquisition made through IoT devices installed in the crop field, maximizing soil wetting through rainfall and reducing irrigated water amount. The average reduction of 16% in irrigation, obtained in simulations and real experiments, indicates a good response of the model to the proposed objective

Integrated agricultural production systems, involving agriculture, livestock, and forest are strategies that improve soil quality. The objective of this work was to evaluate the effect of the integrated crop-livestock-forest system (ICLF) on water availability of a Planosol in the Agreste region of the state of Paraíba (PB), Brazil. The experiment was conducted at the experimental site of the Agricultural Research Company of Paraíba (EMEPA), in Alagoinha, PB. The soil evaluated was a Eutric Planosol, with a moderate A horizon. The following intercrops (treatments) were implemented in June 2015: I. Gliricidia sepium + Brachiaria decumbens; II. Mimosa caesalpiniifolia + Brachiaria decumbens; III. Tabebuia alba + Brachiaria decumbens; IV. Zea mays + Brachiaria decumbens; and V. Brachiaria decumbens. A randomized block experimental design was used, with five treatments. The analyzed variables were field capacity, permanent wilting point, soil available water, granulometry, degree of flocculation, total porosity, macroporosity, microporosity, saturated hydraulic conductivity, resistance to penetration, and aggregate stability index. The results showed that the water availability in the ICLF implemented in the Agreste region of Paraíba had no significant variation after three years. After the three-year period, the ICLF promoted no significant physical improvement in the attributes of the evaluated Planosol.
