Compost and Biochar

Faster & hotter composting – Reduce Nitrogen loss by up to 50%
Reduce compost emissions – Locks up minerals and nutrients
Makes better quality compost – Reduces compost smells

The basic rule of making a good batch of compost is having the right ratio of carbon and nitrogen. Carbon is classed as any dead or brown biomass like brown leaves, woody mulch, sticks, paper, brown dry grass. Nitrogen is anything green or fresh, kitchen scraps, green grass clippings, fresh animal manure, weeds or anything freshly cut from your garden.

A good carbon nitrogen ratio is 25 parts of carbon to 1 part nitrogen. Have a bucket full of Biochar next to your compost bin, when you add a layer of nitrogen sprinkle two big hand fulls of Biochar over the layer so you end up with the fixed carbon Biochar spread evenly through your compost.

Compost activators will help get the compost bin cooking, some common activators are human urine, yoghurt, worm liquid, compost tea, molasses, honey or a bucket full of compost from your last batch.

Biochar added into composts does not rot or break down, it will bond to nutrients, minerals and will reduce nitrogen loss.
