Farm yard Manure is prepared basically using cow dung, cow urine, waste straw and other dairy wastes. It is highly useful and some of its properties are given below:
- FYM is rich in nutrients
- A small portion of N is directly available to the plants while a larger portion is made available as and when the FYM decomposes
- When cow dung and urine are mixed, a balanced nutrition is made available to the plants
- Availability of Potassium and Phosphorus from FYM is similar to that from inorganic sources
- Application of FYM improves soil fertility.
