The use of Sentinel 2 to quantify N, Ca, and K in walnut orchards
Mendes, Maria Beatriz; Farinha, Daniela; Oliveira, Pedro; Mota Barroso, João; Rato, Luís Miguel; Sousa, Adélia; Rato, Ana Elisa’Persian walnut’ (Juglans regia L.) is one of the most consumed nut species in the world, and N, K, and Ca nutrition are critical for its growth and quality. Mineral nutrition management in fruit crops over large areas is a challenging task only possible with a remote sensing data approach and using rapid analytical methods to correlate remotely sensed data with ground data. This study aims to develop and valid...
Pastor.i _ Uma aplicação de smartphone para facilitar a gestão do pastoreio
Sales-Baptista, Elvira; Ferraz-de-Oliveira, Maria Isabel; Cancela d'Abreu, Manuel; Salgueiro, Pedro; Rato, Luís MiguelGrazing in extensive beef farming systems is often manage in an empirical way based on past experience and on the visual appreciation of animal behavior and forage potential. Records of entrances and exits of the animals in the paddocks in a regular basis are rare. However, knowing the occupation period and the animal density, when coupled with biomass defines the grazing pressure and carry capacity. This knowl...
