Composting is most efficient with a carbon-to-nitrogen ratio of about 25:1. [10] Hot composting focuses on retaining heat to increase the decomposition rate, thus producing compost more quickly. Rapid composting is favored by having a carbon-to-nitrogen ratio of about 30 carbon units or less. Above 30, the substrate is nitrogen starved.
The first step of composting at home is to secure a composting bin and location. Bin Type - Composting indoors usually calls for a closed bin method while composting outside in the garden or yard allows for the open bin method without a cover.
John Innes compost is a set of four soil-based formulae for growing media, developed at the former John Innes Horticultural Institution (JIHI), now the John Innes Centre, in the 1930s and released into the public domain. The formulae contain loam, peat, sand, and fertiliser in varying ratios for specific purposes. These composts are used to ...

Harvest of capsicum grown with compost made from human excreta at an experimental garden in Haiti. Reuse of human excreta is the safe, beneficial use of treated human excreta after applying suitable treatment steps and risk management approaches that are customized for the intended reuse application.
A composting toilet is a type of dry toilet that treats human waste by a biological process called composting. This process leads to the decomposition of organic matter and turns human waste into compost-like material. Composting is carried out by microorganisms (mainly bacteria and fungi) under controlled aerobic conditions. [2]
For instance, sheep manure is high in nitrogen and potash, while pig manure is relatively low in both. Horses mainly eat grass and a few weeds, so horse manure can contain grass and weed seeds, because horses do not digest seeds as cattle do. Cattle manure is a good source of nitrogen as well as organic carbon. [3]
In agriculture, a green manure is a crop specifically cultivated to be incorporated into the soil while still green. [1] Typically, the green manure's biomass is incorporated with a plow or disk, as is often done with (brown) manure. The primary goal is to add organic matter to the soil for its benefits.
