how did the process of Adding manure to the soil begin
Answers
High nutrient content could destroy your plants.
Therefore dilute manure with soil and hasten the decomposition method by incorporating the manure into soil surface before the area plantations.
You had a test a manure before hand as there’s no way of knowing what its nutrient content is therefore perform
this during early fall to provide the manure to break down before you plant the spring in the soil.
People used to throw wood ash, fish remains and slaughterhouse waste on the
vacant land just to get rid of them. When the people noticed that the grass, bushes
and shrubs on that spot began to grow very well, they realised the growth of their
crops would also be improved. They also realised that the quality of land would
be improved by supplying organic remains to the soil. Thus they began adding
manures to the soil in their land.
