Natural Fertiliser – in this case FYM, or Farm Yard Manure
Animal Manure is of course a natural product. As such it is perhaps no surprise that it’s values are substantially smaller.
Cow manure has an NPK % value of 0.6-0.4-0.5.
Horse manure’s value is 0.7-0.3-0.6.
Interestingly, one of the highest animal manure values is that of Rabbit, which is 2.4-1.4-0.6.
If you make your own garden compost from garden waste etc., it’s values are likely to be 0.5-0.27-0.81.
So it can be clearly seen that animal manures are nothing like as potent as some artificial fertiliser. Nor can they deliver specific nutrients like and artificial fertiliser can. However, they can and will improve the health of the soil because they introduce organic matter the soil-bourn life can feed off, which then goes on to improve the soil structure, which in turn benefits nutrient up take, root growth, the increase of oxygen in the soil and improved drainage. An inorganic or artificial fertiliser cannot and will not do that.
