It is not uncommon for farmers to report higher yields and better protein and oil percentages, while some farmers are reporting phosphorus and nitrogen readings at never-before-seen levels after six or seven years of use. Using it on cereal crops, they state that they could happily crop without any fertilizer input during tough times.
Chicken is not a ‘one year wonder’. Rather, it is a program that should be executed over at least three years to allow the manure to work into the soil so micro-organisms and nutrients can properly release their valuable elements, break down the old stubble and improve the soil quality over a period of time.
Chicken manure takes time to spread, either by contractor or hiring a machine, so it may not be for everybody. At the spreading rate of 2 to 2.5 tonnes per hectare, there is definitely not enough manure to go around for everybody.
