Sandy and critical land are usually not productive in terms of food productions. On the other hand, the need for land for agriculture has increased, and thus technologies are needed to transform marginal lands to become more arable.
The first step that we perform is to improve the soil structure in the sand to reduce porosity and salinity by adding SAN Tanaman, SAN Pembenah Tanah and SNN to the soil.
Next is to prepare for water usage to irrigate the land by building irrigation canals through the plot. For water needy plants, we use water proofing layer to reduce soil porosity.
Beach sand possesses extreme climate, high humidity, and high salinity. To protect the soil, we create a micro climate by planting trees as wind breakers along the beach.
