Sustainable Intensification of the Montado Ecosystem: Evaluation of Sheep Stock...
Carreira, Emanuel; Serrano, João; Shahidian, Shakib; Infante, Paulo; Paniágua, Luís; Moral, Francisco; Paixão, Luís; Pinto Gomes, C.; Lopes de Casto, J.The objective of this study was to determine how application of dolomitic limestone and stocking methods (continuous stocking or deferred stocking) affect the soil compaction, sheep grazing location, height, and nutritional value of pastures when the pasture growth rate is at its maximum. A 4 ha field at Mitra farm—University of Évora—was divided into four plots: P1 and P2—without application of dolomitic limes...
Avaliação da estabilidade temporal de zonas homogéneas de gestão (ZHG) em pasta...
Serrano, João; Marques da Silva, José; Paniágua, Luís; Moral, FranciscoA Agricultura de Precisão (AP) procura validar ferramentas tecnológicas que permitam captar a variabilidade espacial das culturas e do solo, o que constitui a base para o estabelecimento de zonas homogéneas de gestão (ZHG). Os sensores que medem a condutividade elétrica aparente do solo (CEa) são exemplo destas ferramentas no levantamento da variabilidade espacial das caraterísticas do solo. A estabilidade temp...
Pasture Quality Assessment through NDVI Obtained by Remote Sensing: A Validatio...
Serrano, João; Shahidian, Shakib; Paixão, Luís; Marques da Silva, J.; Paniágua, LuísMonitoring the evolution of pasture availability and quality throughout the growing season is the basis of grazing management in extensive Mediterranean livestock systems. Remote sensing (RS) is an innovative tool that, among many other applications, is being developed for detailed spatial and temporal pasture quality assessment. The aim of the present study is to evaluate the potential of satellite images (Sen...
