Miyawaki was a technique introduced by Japanese botanist Akira Miyawaki. This technique is about building dense native forests. This method involves planting native trees which can grow 10 times faster and 30 times denser.
Creating urban forest using Miyawaki method, be familiar with the following:
1. Soil texture:
Knowing soil texture helps to determine the following:
a. Water holding capacity
b. Capacity of root perforation
c. Water infiltration
d. Retention of Nutrients
Loamy soils are mostly preferred because of the presence of organic matter thus providing right amount of oxygen, nutrients and water.
2. Selecting Tree species:
Native species are selected because they have very good growth rate and also can be maintenance free which means they can survive easily due to local environmental conditions.
Things to note while selecting the right species of plants:
a. Maximum height they can reach
b. Species age
c. Choose 6 to 8 species which grow in the forest
d. Check ideal height of species because they will be placed around 1 square meter distance from each other
3. Select an area of land:
Choose the right area of land and have facilities for borewells or tanks as they need to be watered on a regular basis for the first 2 years.
4. Plant trees:
a. Excavate soil from the ground about 4 feet. Mix fertilizers, water retainers, and level them using hand tools by closing them.
b. Dig pits 12 to 14 inches wide and 12 to 14 inches deep.
c. Place the sapling. After planting the sapling, insert bamboo sticks in the soil close to the plant.
d. Maintain some distance between each sapling and try to place different species of plants nearby. Add mulch in the soil for 5 inches and water them.
To conclude, you will find dense forest grown over a period of two years with regular watering of plants. With this technique, we can develop a fast growing self sustained forest.
