Old dried out cow poo has probably lost a lot of it's nutrient value, leached out with gravity and rain etc. Any manures need to be made into a compost material asap to retain as much of the nutrient as possible. Or you dig it into your soil over 6-12 weeks and with air water and turning it, it breaks down into the soil. The greatest benefit of organic material put back into the soil is it makes the soil loose and friable, which means it then drains well.
