Why do compost heaps need water




















Dried worms are a sure indication. To raise the moisture level, spray the bin with water or add food items with higher water content. A high temperature is desirable in a backyard compost pile, as it will accelerate the decomposition of materials. Heat can also aid in breaking down pathogens and weeds. The ideal temperature in a composting pile is between and degrees Fahrenheit. To increase the temperature of a compost pile, turn the pile weekly. Turning the pile will allow oxygen to flow, maintaining the aerobic condition of the pile and regenerating heat.

Dry and fibrous with little rotting: Usually caused by too little moisture and too much brown material.

Alternatively, add fresh manure at one bucket for every 15cm 6in layer of compost, fish, blood and bone fertiliser at g 9oz per 15cm 6in layer of compost, or sulphate of ammonia fertiliser at g 5oz per 15cm 6in layer of compost.

Scooping out the top of the pile to create a concave shape will maximize water absorption, so that rainfall can help replenish the moisture that is lost from the piles as steam. However, if the pile is overly saturated, anaerobic odors and leachate will be produced.

Therefore, in prolonged wet conditions, the pile should be shaped to form a peak that will minimize absorption by shedding water.

Both of these shapes are illustrated. Water can be added to the compost pile in various ways. Hosing yard waste as the windrow is turned or turning it on a rainy day can help get water into the pile. Overhead sprinklers on a concave shaped pile also work well. By applying water slowly, it is more likely to infiltrate the pile, rather than running off the surface. Another method uses a drilled pipe as an injection probe, delivering pressurized water from a water truck to the center of the pile where it can be readily absorbed.
