Soil Fertility Index

Grundo’s model can ingest satellite data of a target region and estimate the content of organic matter. The model selects relevant wavelengths from the satellite data and performs calculations to quantify the amount of organic matter based on the latest research. Since organic matter and fertility are strongly correlated, we can assess the level of fertility of the soil.

Our Fertility Index applied to two different regions in Indonesia. On the left, we have the region of Kalimantan, where peatlands are present, and potentially the index could be used to identify them (between brown and pink regions). On the right, we have a region with farms where the fertility index could be used for identifying portions of land that are good for agriculture. Currently, the index is based on firm theoretical models and subsequent calibration and ground validation will enhance its accuracy.
