Question: I live near an old dairy farm. How can I make the best use of old, dried cow manure?
Ideally, you should compost this manure. Manure in our climate does not readily decompose due to our low rainfall and humidity. In wetter climates, manures compost over time. Using uncomposted manure can pose a health concern if you are growing vegetables, particularly leafy vegetables. Keep it out of direct contact with human food as much as possible.
Good composting methods will take many months to finish manures completely. Compost piles in our climate should be kept out of the wind and direct sunlight. Keep them moist, but not wet, turned frequently.
