Commercial composting always takes time, energy and space, and even related equipment to compost correctly. Microorganisms responsible for composting need food, water, air and the proper temperature:

  • Moisture: The water content should be controlled within 50%-60%. For example, when  squeezing a handful of composted material, it should feel like a damp sponge; it will wet your hand with no free water drops. If the moisture is too high, horse manure could be mixed with bulking materials, like straw, leaves or hay, while you can choose a solid liquid separator for manure dewatering quickly as well.
  • Oxygen & Temperature: The most appropriate temperature range is 54oC- 66o At 60oC or higher, most internal parasites, many weed seeds and fly larvae in horse manure materials could be killed. But if higher than 71oC, the microorganisms would also be killed. Hence, it is essential to regulate the oxygen and temperature levels by using composting machine to turn or invert the compost pile regularly, like about twice a week. Compost turner accelerates the composting process by physically turning the manure and providing a constant flow of air, improving composting quality and efficiency.
  • C:N ratio: Carbon and nitrogen are the two fundamental elements in composting. For microbes, carbon(C) is the main source of energy while nitrogen(N) always can be used for forming proteins. In order to ensure successful horse manure composting, people should make sure the proportions of C and N in balance(here could be in the range between 25:1 and 30:1).
  • Compost pile: For better fermentation, horse manure piles should not be built too small or short. Generally speaking, the height of pile is about 1.5m, the weight is about 2m, and the length could be chosen depending on composting environment at the scene, so as to use compost turner machine handily.
