This method includes providing raw agricultural waste to be treated, adding to the raw agricultural waste an effective amount of a composition comprising a quaternized amino methylated polyacrylamide polymer for separating the raw agricultural waste into a mixture having a liquid portion and a nutrient solids portion, mixing the composition with the raw agricultural waste to facilitate the separation, and subjecting the mixture to at least one mechanical separation means for segregating the separated liquid portion from the separated nutrient solids portion. A method for transforming raw agricultural waste into a clarified liquid portion and a dewatered nutrient enriched solids portion is also provided.
