Spatial Variability and Pattern of Selected Properties of Agricultural Soils in the Czech Republic Measured by Indirect Proximal and Remote Sensing
Original language description
Spatial and temporal variabilities of soil properties were monitored within a 12-ha field over several consecutive years. Particle-size distribution, total carbon content (Ct), and pH were monitored. Soil samples were taken from points on a regular square grid. Additionally, the variability of soil properties was evaluated by proximal measurement methods including draft force measurements, soil electrical conductivity (ECa), and crop yield mapping. Remotely sensed bare-soil satellite images were obtained and digital elevation models were made. All the observed variables showed spatial variability, but the spatial patterns of Ct, pH, EC, and crop yield were temporally stable. Results were processed using statistical and geostatistical methods. Variograms and their parameters were used to describe spatial dependencies between observed variables. Significant dependencies were observed between monitored soil properties and indirect methods, indicating utility in the proximal approach.
