Keeping composting simple
Compost made easy
In 8-12 weeks, the straw from a hectare of paddy can produce 2.5 tonnes of good quality compost, which when added to the soil provides 50 kg of nitrogen, or 40-50% of the total nitrogen requirements of a rice crop. Cutting fertilizer costs by half is a huge advantage for farmers as they struggle with debt from the need to buy more and more fertilizer each year.
The basic compost combination is dry matter, fresh green matter and a microbial input. Rice straw, dried leaves and even coconut fibre are good sources of dry matter. Freshly cut leaves and weeds, banana trunks, water hyacinth, or any plants in and around the fields and gardens are used as green matter. The microbial input helps to transform the biomass into the nutrient-rich material we call compost, whether it is fresh soil, forest humus, animal manure or fresh compost. Handfuls of wood ash add phosphorus and potassium and even the basic combination can be adapted. If a farmer has no more green matter, he will still get compost but of a different quality. And if manure is in short supply, it helps to add a diluted solution of cow or pig dung with rice straw and other dry matter. This promotes the growth of microbes, nitrogen content and decomposition, and is a cheap and easy way to overcome the lack of green matter or manure.
