Irrigation with sugarbeet processing waste water was studied at three locations for 2 or 3 years where perennial grass and alfalfa were irrigated by flooding specially graded fields. Experimental sites were scheduled for irrigation at intervals of 1, 2, or 4 weeks. This schedule was maintained for the first year until the weekly irrigated plots were discontinued because of excessive loading. Waste water was sampled twice weekly from the sugar factories, and water samples were extracted from the soil at depths of from 15 to 150 cm each time the fields were irrigated. All water samples were analyzed for chemical oxygen demand, total nitrogen, phosphorus, potassium, electrical conductivity, calcium, magnesium, sodium, sodium absorption ratio,... |
