The ideal ratio of Carbon to Nitrogen (C:N) is 30:1 (30 parts carbon material to 1 part nitrogen material).
Good compost is produced by blending leafy ‘green’ matter with harder ‘brown’ matter. ‘Green’ matter includes grass clippings, vegetable scraps, and soft green prunings. ‘Brown’ matter is shredded woody branches, dried leaves, straw and shredded newspaper.
Try to add brown and green matter in layers, not making any layer too thick. If you put in too much green matter, the compost may go sludgy and smelly. Too much brown matter and it won’t break down quickly. With a good balance of the two, composting will proceed quickly.
Finally, the addition of some Yates Dynamic Lifter Soil Improver & Plant Fertiliser and a small amount of soil will encourage the introduction of composting microorganisms and provide them with additional nutrients. This will promote the breakdown of the material and better compost.
