If this waste is a biodegradable substance then it will very helpfull for growing crops
if the waste is non-biodegradable substance then it will very harmfull it may cause pollution 
If eroision did not take place in the earth then that would be a problem if the waste is of non biodegradable then the waste will be keep on forming layers in the land so it prevents the trees to grow there and that would result in many problems. And if that waste is biodegradable waste then the nutrients, minerals etc..totally will decompose in to the soil. Hope this helps.pls mark as brainliest...
