Remote Sensing enables the acquisition of planting information through the spatial resolution of multispectral images obtained from Remotely Piloted Aircraft (RPA) in situ. This study aimed to evaluate the application of agricultural gypsum in citrus orchards using precision agriculture tools and image-based analysis. Multispectral images were acquired at three flight altitudes (80, 100, and 120 m) to assess their influence on canopy area delineation and the Normalized Difference Vegetation Index (NDVI). The experimental design consisted of five gypsum application rates (0.0, 0.6, 1.2, 1.8, and 2.4 t ha⁻ 1 ) applied to a citrus orchard located in Capitão Poço, Pará, Brazil. The variables analyzed were NDVI – derived from near-infrared and red reflectance bands – and canopy area, extracted from vector polygons of tree crowns. The results showed that the 0.6 t ha⁻ 1 dose yielded the greatest canopy area. Additionally, flights at 80 m altitude provided higher spatial resolution, enabling more precise delineation of citrus canopies. This enhanced detail supports improved vegetation monitoring, emphasizing the advantage of higher spatial resolution in precision agriculture.

Black pepper (Piper nigrum L.) is a crop of significant economic importance in the Amazon, especially in the state of Pará, where intensive production systems predominate. Understanding the spatial variability of soil attributes and their relationship with plant vigor is essential to optimize agricultural practices and input use. Geotechnology-based approaches enable the generation of more precise management zones, contributing to efficient resource use and increased profitability. This study aimed to delimit potential management zones in black pepper crops based on the spatial analysis of soil bulk density (BD) integrated with the NDVI (Normalized Difference Vegetation Index), evaluated using the Bivariate Moran’s Index. The research was conducted in a production area in the municipality of Baião, Pará, Brazil, using soil samples to determine bulk density and UAV images for NDVI calculation. Data were interpolated by kriging and analyzed to identify spatial associations between soil compaction and NDVI. Soil bulk density ranged from 1.14 to 1.80 Mg m−3, while NDVI values ranged from 0.07 to 0.91, revealing a clear inverse spatial relationship between soil compaction and vegetative vigor. The integration of BD and NDVI allowed the delineation of site-specific management zones, supporting more efficient decision-making in precision agriculture.
