BRIEF DESCRIPTION OF THE DATASET 
This dataset was collected as part of a study that investigated the seasonal variability of dissolved organic phosphorus (DOP) in agricultural drainage waters, and also determined how much of this DOP can be converted to inorganic phosphorus through enzymatic hydrolysis. Water samples collected in several occasions (4 seasons) throughout the year 2019 and analyzed for DOP, enzymatically-hydrolysable P and FeO-strip P (the amount of P extraction from iron-impregnated filter paper in contact with drainage waters).
