Sustainable Farming – 2

So now that we had decided to have cows, we were looking to optimize the yield, and we came across the concept on Biogas plant.

What is a biogas?

Biogas refers to a mixture of different gases produced by the breakdown of organic matter in the absence of oxygen. Biogas can be produced from raw materials such as agricultural waste, manure, municipal waste, plant material, sewage, green waste or food waste. Biogas is a renewable energy source.

In our case – we have decided to use cattle waste and agricultural waste.

What is Biogas plant?

A biogas plant is the name often given to an anaerobic digester that treats farm wastes or energy crops. It can be produced using anaerobic digesters (air-tight tanks with different configurations). During the process, the micro-organisms transform biomass waste into biogas (mainly methane and carbon dioxide) and digestate.

Why is it useful?

Biogas can be used for electricity production, for cooking, heating, etc

In addition to this, the slurry that is generated, is a very fine manure and can be directly (or after processing) applied to farms.

Sustainable Farming – 1

Till now, it was about increasing the productivity and efficiency. But the main question was – how do i make it sustainable?

Sustainable – ecologically

Sustainable – financially

So let us discuss ecological sustainability in this post. The first one begins with soil. In order to farming being sustainable we need to opt for organic farming.

However buying organic compost/manure, preparing vermi-compost, was not a very viable option for the kind of scale we were planning. So how do we do it?

There was only one answer – Cows. A single cow on an average gives 10kg of dung everyday. That is 300-350 kg per month.

Cow-dung is an excellent manure and cow-urine an very potent insecticide. All in all we decided that we will have cows at the farm.
