Aplicação de sensoriamento remoto e geoprocessamento da palma forrageira para desenvolvimento da produtividade agropecuária em regiões semiáridas

Application of remote sensing and geoprocessing of forage palm for the development of agricultural productivity in semi-arid regions

Abstract

The semi-arid region has a diversified economy in the agricultural sector, but droughts cause great damage to agricultural activity. For this reason, fodder palm has emerged as an alternative for supplying dairy cattle with food. With this research, the spectral signature of fodder palm at different crop ages was determined through remote sensing and geoprocessing, using satellite images. The multivariate analysis showed that the years with above-average rainfall are in opposition to the grouping containing the lowest reflectance values (in the visible and near-infrared bands), which indicate the periods of greatest coverage of the soil surface by forage palm in relation to native vegetation. However, it was possible to monitor the forage palm at different stages of development, providing support for decision-making regarding the management of areas cultivated with palm to increase milk production in the semi-arid region.
