Determination of homogeneous zones for liming recommendations of black pepper using geostatistics

Abstract: A B S T R A C TStudies aimed at determining homogeneous zones and the spatial variability of soil characteristics may improve the efficiency of agricultural input applications. The purpose of this study was to determine homogeneous zones for liming applications and to characterize the spatial variability of characteristics related to soil acidity and productivity in an Oxisol cultivated with black pepper (Piper nigrum L.). This study was carried out in São Mateus, state of Espírito Santo, Brazil. The experimen… Show more

“…The spherical model was the most frequent among the fitting models, followed by the Gaussian and exponential models. Greater fits of the semivariograms for spherical models in attributes of soil organic matter (SOM) were observed by Leite et al (2015) and Gontijo et al (2016). For the attributes SB, N-LOM and C-LOM of the 0-0.20 m layer and SB, V%, N-LOM and C-LOM of the 0.20-0.40 m layer, PNE was verified.…”
