In this video M.R. Hari explain why the setting up of a Miyawaki forest is as costly as it is. It requires an investment of nearly Rs 395/- per one square metre to prepare a seedbed. This is because the potting mixture contains soil, rice husk, coir pith and dry cow dung in equal quantities to ensure that the saplings get enough nutrients, the soil retains water and does not solidify. The amount also covers the cost the saplings, the expenses incurred in tending them in grow bags that contain similar potting mixture, transportation expenses, and so on.
