Fertilisations based on compost or composted manure are better than fresh manure. Nutrient inputs can be chemical inorganic fertilizers, manure, green manure, compost and minerals. These worms thrive in rotting vegetation, compost, and manure. They can also be collected from compost and manure piles. Also organic mulch, especially mushroom compost, shows good results. Composting value will ultimately be limited by the market demand for compost product. Covering with compost or mulch provides protection from frost. Unwanted living plants (or weeds) can be discouraged by covering with mulch/compost. Microbes are also important in agriculture for the compost and fertilizer production. Warmth and moisture contribute to this process, similar to creating compost fertilizer. Other sources include exposure to potting mix and compost. See Compost ingredients&colon; Human Waste. Everything else is donated as compost, which enriches soils with nutrients. Offering alternate disposal options like recycling and compost centers is also recommended. They also make excellent compost and plant bed material.
