Monitoring soil conservation techniques via UAV for sustainable production of i...
Sousa, Lizandra de Barros de; Montenegro, Abelardo Antônio de Assunção; Isidoro, Jorge; Silva, Thieres George Freire da; Almeida, Thayná Alice BritoContext: Sustainable agricultural production in semiarid regions is limited by water scarcity and soil degradation. Forage cactus (Opuntia stricta) has high drought tolerance but requires effective water and soil management to maximize yield. Objective: To evaluate the effects of mulching and intercropping with gliricidia and moringa, under treated wastewater irrigation, on forage cactus productivity and soil p...
Spatiotemporal Analysis of Rainfall and Droughts in a Semiarid Basin of Brazil:...
de Barros de Sousa, Lizandra; de Assunção Montenegro, Abelardo Antônio; da Silva, Marcos Vinícius; Almeida, Thayná Alice BritoPrecipitation estimation is a challenging task, especially in regions where its spatial distribution is irregular and highly variable. This study evaluated the spatial distribution of annual rainfall in a semiarid Brazilian basin under different regimes and its impact on land use and land cover dynamics. Climate Hazards Group InfraRed Precipitation with Stations (CHIRPS) records and observed data from 40 weathe...
Coupling Water Resources and Agricultural Practices for Sorghum in a Semiarid E...
Carvalho, Ailton Alves de; Montenegro, Abelardo A. de A.; Lima, João L. M. P. de; Silva, Thieres George Freire da; Pedrosa, Elvira Maria RegisWater scarcity and changing rainfall distribution have caused uncertainties in relation to agricultural production in semiarid areas. In this context, water reuse for irrigation is a promising alternative, although requiring irrigation and agricultural management. Production of forage plants is strategic for semiarid areas due to their high tolerance to stresses and use as animal fodder. The objective of this w...
Uso de coberturas alternativas do solo para o controle das perdas de solo em re...
Lima, Cleene Agostinho de; Montenegro, Abelardo Antônio de Assunção; Lima, João L. M. P. de; Almeida, Thayná Alice Brito; Santos, Júlio Cesar Neves dosA região semiárida do nordeste brasileiro é marcada por elevadas incertezas quanto à ocorrência de chuvas intensas, bem como por anos sequenciados de secas. Esses fenômenos naturais, somados à reduzida utilização de práticas conservacionistas, podem gerar degradação dos solos. Nesse contexto, o presente estudo objetivou avaliar a importância do uso de cobertura morta e espécies de oleaginosas não convencionais ...
