Abstract

soil physics, satellite mapping, Qgis, GIS, soil spatial variability

The spatial variability of the physical property resistance to penetration in a soil with agricultural vocation under a rice cultivation system was studied. For the design of spatial variability maps in a study area of 22.6 ha located in the town of San José de la Vega, Municipality of San José de Cúcuta, the different variables were classified and analyzed, achieving the representation of the information obtained in the field using the "QGIS" software for the classification and distribution of the study area. A quantitative experimental method was carried out for the study, which was divided into a systematic grid with 27 points located by means of coordinates. At each point, measurements corresponding to the physical properties were made, which were: resistance to penetration, where four measurements were taken for each depth level (0-5cm, 5-10cm, 10-15cm and 15-20cm) and averaging each measurement. In the 10 to 20 cm resistance, significant values were recorded in the ranges of 3.8 and 8.42MPa from the sampling points. The moisture retention measurement is made up of the ranges of 31.1% minimum and 50.2% maximum.
