SPATIALITY OF SOIL CHEMICAL ATTRIBUTES IN A BANANA CULTIVATION AREA IN WEST BAHIA

ABSTRACT Irrigated fruit growing in the São Francisco Valley has been standing out Northeast region of Brazil and incorrect management fertilization caused problems physical / or chemical degradation soil. The work aimed to evaluate spatial variability attributes a Latossolo Vermelho-Amarelo (Oxisol) grown with banana (Musa spp). study was carried irrigated perimeter Nupeba Riachão das Neves BA. In an area cultivated for 18 years silver fertigated by micro sprinkling. April 2017 simple soil samples were collected at depths 0 -0.20 m 0.20 -0.40 m, from experimental grid consisting 40 georeferenced points spaced every 10 meters. determined: pH (H2O); Organic carbon; Phosphorus (P); Potassium (K+); Calcium (Ca2+); Magnesium (Mg2+) Potential acidity (H + Al) sum bases (BS), cation exchange capacity (CEC) base saturation (V%) calculated. results analyses evaluated using descriptive statistics geostatistics technique. analysis identified normality data. confirmed, allowing making maps. analyzed low fertility (V <55%) inadequate correction can reduce availability nutrients implanted crop, susceptible use irrigation. distribution maps allow visualization area, application inputs varying rates, aiming homogenizing fertility.
