Project Merbok – Two Years On

It has been two years since we broke ground at Project Merbok. The site was once a windswept hill covered with lalang (Imperata cylindrica) without any trees. The landowner wanted to do up the place as a retreat centre for his employees. A small house would be built, and behind the building there were to be fruit trees, vegetables, livestock, and fish ponds, all grown organically. To fulfill this vision, we did some earthworks for the ponds and vegetable terrace, brought in lots of compost, and planted many trees. Today, the landscape is much different from what it was two years ago. It’s like a little green oasis in the open grassland. We would like to share some photos and what we learnt.

Windbreak

We previously posted that creating a windbreak was one of the most important tasks. The site is a hilltop and the highest point for a good distance all around. Without the windbreak, most of the fruit trees and edible plants would suffer. Despite being planted on the harshest area with the poorest soils, the Casuarina (Casuarina equisetifolia or Rhu) have been growing rapidly and doing well. The Eugenia (Eugenia oleina, or Syzgium campanulatum) are growing as well, but definitely slower. In some areas, we had to help them with competition from creepers and tall grasses. As our windbreak trees grow, they will slowly create a micro-climate more conducive for the other plants.

A Fixation on Nitrogen Fixation

2014-01-11 09.47.03Nitrogen is one of the three macro-nutrients needed for healthy plants. It is the eldest brother N within the NPK trio. In the tropics, this vital ingredient is often found lacking in cultivated soil. From my experience using the soil test kit in various gardens in Singapore, nitrogen always shows up as “low”.

How can this be! There are tons of nitrogen in the atmosphere, roughly 78%. However, atmospheric nitrogen doesn’t just flow into the soil readily as it is inert. Continue reading
