Spatial correlation of soybean yield with the chemical attributes of an Oxisol

Soybean is currently the most cultivated oilseed in world. The objective of this study was to analyze chemical attributes Oxisol correlated with soybean productivity. evaluated were grain productivity, soil properties organic matter contents, phosphorous, pH, potassium, calcium, magnesium, hydrogen + aluminum, sum bases, cation exchange capacity (CEC), base saturation, liming requirement; penetration resistance at 0.0-0.10 m, 0.10-0.20 0.20-0.30 and 0.30-0.40 m. Soil submitted a descriptive classic analysis help RBio software. In semivariogram analysis, requirement, m showed pure nugget effect, meaning no spatial dependence. conclusion, CEC attribute that best described yield data dystrophic Red Latosols. Attributes matter, phosphorus, CEC, 0.00 0.30
