How to use the Manure?
The best way to use the manure is to get it composted. Manures generally have a high ratio of nitrogen compared to other composting ingredients. And so it needed to be composted with some dry leaves etc which have a higher ratio of carbon material. You should maintain the proper C:N ratio for the compost to work well.
Use two different beans one for the mixing the manure with dry leaves etc. and the second one is for the decomposed one.
First mix the manure with dry leaves etc and keep it for one month or so for decomposition. Keep adding water from time to time for provide moisture. It will heat up and can reach up to a temperature of 130 degrees. Once you realize the temperature has been settled down it is time for the compost to be shifted to the second bin.
Some manure will take more than that. Spread the composted manure over the garden 1/2 inch thick. Add more in case the soil is very poor in quality with little or no organic matter.
Don’t add excessive amount of water to the compost. If you are doing it during rainy season it is important that you cover the bin with plastic.
Use gloves through out the entire process while handling manure.
Wash your hands properly after finishing the work.
Using raw manure is not advisable but if you still want to use it, apply it 60 days prior to planting any vegetable. Plant any cover crop in between and let the manure mature.
