Project Background

Sandy soil usually is not appropriate for planting because of its high porosity. PT Indmira offers the technology to convert sandy soil to be a productive land for agriculture. PT Newmont Nusa Tenggara has applied our technology to grow Casuarina equisetifolia along the coast around their mine as their social responsibility.

Total Area: 1 ha

Duration of Work: 1 year

The Challenge

Sand on coastal area, High porosity, Low rainfall intensity

High salinity

High temperature > 30 degrees celsius

Extreme wind

The Handiworks


Casuarina equisetifolia trees are planted in a 4x4 meter patterns with the depth of 20 to 30 cm

Soil Modification

Biostimulants such as Soil Amelioran, F4, SAN tanaman, and POC SNN are placed inside the planting holes, followed by watering that saturates the soil. Watering is carried twice a day, morning and afternoon, for two weeks.


After two weeks, Casuarina equisetifolia is planted. In the first three months, saplings are watered twice a day. Fertilizers, POC SNN dan SAN, are applied every three months.
