Im not sure but since 14000 kg/ is the soil that is lost per 10000m^2. Do i multipy this by 3.8% to get how much organic material was there?
ok..so first you want to get rid of the fractions, so what u need to do is find a common number for it.. for 3 and 4 its going to be 12 now multiply everything by 12... what you should end up with is 6b+4B = 120.. now solve! and you should get 10.. ps. the
