We are starting on a 10-acre piece of land in Johor, Malaysia. It is situated close to Kota Tinggi, a place north-east of Singapore known for fireflies and waterfalls. Kevin approached us recently about this land owned by his family. He wants to do organic farming on it and provide good livelihoods to people working there. The majority of the area will be a mixed fruit orchard but there will be aquaculture and vegetables too. He does not have any farming experience, but we felt that he has good intentions and is someone we can work with.
The land was previously a 3 year old rubber monoculture plantation. When we met him, the land had already been cleared of vegetation by a tractor. He said that the contractor was going to dig up all the tree roots and dispose of them. We recommended against that for many reasons:
- The roots, despite being dead, still holds the soil together against erosion on his sloping land. Over time, they will rot and act as a slow-release fertilizer.
- Digging mixes up the naturally-formed soil horizons and disrupts all the organisms in the soil.
- Aerating soil in this manner introduces a rush of oxygen into the soil. That’s a short-term benefit with long-term losses. With the high temperature and moisture here, this means that organic matter and humus decompose rapidly and become lost as carbon dioxide to the atmosphere.
- Without any big trees or plants to absorb the suddenly available nutrients, they will be lost to the atmosphere (oxidized) or washed away by the rain (leached).
After the first meeting, we scheduled a date to visit the land. Continue reading
