Abstract

Abstract: The applications of precision agriculture techniques in the management of soil fertility has optimized the use of fertilizers enabling more sustainable agricultural systems. The objective of this study was to evaluate the temporal variability of some soil chemical properties under grain cultivation in the municipality of Paragominas - PA, through the use of precision agriculture techniques. The study was conducted on 17 farms in the years 2009 and 2010, measuring results of 1945 soil samples. The soils cultivated with grains had low acidity, base saturation below 50%. Soil fertility is evaluated by the results obtained from medium to high.   Key-words: fertilization, fertility, management.
