The spatial variability of soil and plant properties has been a concern of researchers, since the variation of any phenomenon in space or time, whether caused by natural processes or by man-imposed actions, has always existed and need considered. The objective was relate spatial variability of chemical attributes, including carbon and nitrogen, to pasture and sugarcane areas in the west of the state of São Paulo. A total of 36 points were sampled in the west of the state of São Paulo in areas of pasture and sugar cane. For each point were collected soil chemical data at depth of 0 cm to 30 cm in March 2015. For identification of spatial dependence, data interpolation and for the elaboration of the maps, the geostatistical analysis was used including adjustment of the semivariogram. To relate the maps of soil chemical attributes interpolated by geostatistical and kriging with grazing and sugarcane areas, the land use map was obtained. There was spatial dependence for the chemical attributes analyzed and the ranges of values showed soil-related variability. The highest values of nutrients, carbon and nitrogen in the areas of sugarcane production, evidencing the positive effect of crop management on the soil when compared to pasture areas. |
