Abstract Agriculture 4.0 demands the development of technology and science to continue to develop in the world of agriculture. Agriculture 4.0 applies the use of the latest technology to increase efficiency in agriculture both in terms of on-farm to off-farm. Provision of fertilizers and plant nutrients is an important factor in plant growth, but the fertilizer and nutrient needs of each plant have different amounts depending on the condition of the soil media. Nowadays physical and chemical measurements of soil require laboratory analysis to determine soil conditions in the field, this method requires time-consuming analysis and cannot represent the physical and chemical properties of the soil in a timely manner. One form of soil properties is the electrical conductivity of the soil (EC) where this EC value can represent the physical and chemical properties of the soil. Veris 3100 is one instrument that can measure EC in real-time. This EC value can also determine land fertility as a soil analysis before land preparation. This research was conducted with a land area of 40x60m, while the veris 3100 takes EC data once every 1 second so that the speed of the tractor has a considerable influence on the amount of data taken by the Veris 3100. The speed of the tractor in this study uses a gear composition of Low -2 (L2).. By the time the data was taken, the 3100 version recorded more than 3000 data. Of course, this data needs to be searched and needs to be averaged by 10x10m so that it can be compared with the soil component data. The Relation between soil EC and some soil properties has a not very good Relation with the largest R square value found in the Relation between soil EC and cation exchange capacity with a value of 0.1471.
