Resumo
Transformar áreas com pastagens, antes degradadas pela pecuária extrativista, em sistemas tecnificados altamente produtivos é um dos caminhos que garantirá sustentabilidade na prática de produzir carne no território nacional, assim, fundir técnicas agronômicas e sistemas de irrigação proporcionaram fluidez ao processo. Deste modo, este trabalho teve como objetivo avaliar o manejo da irrigação em uma área irrigada por pivô central no município de Cassilândia-MS que recebeu a integração lavoura-pecuária pela sucessão entre a forrageira Panicum Maximum BRS Zuri e a soja (Glycine max (L.) Merril), analisando-se o conjunto solo-planta-atmosfera. No solo, valores acima de 200 mm.h-1 para a taxa de infiltração básica merecem atenção do ponto de vista de lâmina aplicada pela irrigação; além disso, o armazenamento de água do solo foi medido ao longo das safras por uma sonda “Sentek”, o que permitiu comparar e validar que o software de manejo “FieldNet Advisor” licenciado pela fazenda é aplicável ao manejo da irrigação. Estimar a evapotranspiração dentro da área irrigada, através de leitura de sensores, permitir propor o coeficiente corretivo de 0,965 em relação a estação operada pelo INMET do município de Água Clara – MS. O manejo da irrigação fora bem aplicado dentro dos parâmetros analisados.
Transforming areas with pastures, previously degraded by extractive livestock, into highly productive technified systems is one of the ways that will guarantee sustainability in the practice of producing meat in the national territory, thus, merging agronomic techniques and irrigation systems provided fluidity to the process. Thus, this study aimed to evaluate the irrigation management in an area irrigated by central pivot in the municipality of Cassilândia-MS that received the crop-livestock integration by the succession between the forage Panicum Maximum BRS Zuri and soybean (Glycine max (L .) Merrill), analyzing the soil-plant-atmosphere set. In the soil, values above 200 mm.h-1 for the basic infiltration rate deserve attention from the point of view of the depth applied by irrigation; In addition, soil water storage was measured throughout the seasons by a “Sentek” probe, which allowed comparing and validating that the “FieldNet Advisor” management software licensed by the farm is applicable to irrigation management. Estimating the evapotranspiration within the irrigated area, through sensor reading, allows proposing the corrective coefficient of 0.965 in relation to the station operated by INMET in the municipality of Água Clara - MS. Irrigation management was well applied within the parameters analyzed.
