Soil Scanning


By using electrical conductivity (EMI) technology combined with an RTX GPS system, we analise all soil physical, chemical and topographical properties spatially across any crop field with an intensity of up to one reading per 40m² and an accuracy of up to 4CM.

Making use of calibrated Emi data points across the field we visually map all soil properties you would need to optimise productivity, ensuring sustainability. With this data farmers can determine their soil potential more accurately, identifying management zones based on permanent rather than dynamic properties. These management zones can then be utilized according to its potential through variable planting and/or fertilising, assisting farmers in the optimisation of inputs.
