Since 1967 a permanent trial has been carried on in La Platina Experimental Station. Two rotations and two level of nitrogen are compared factorially. Rotations: 1. Three years of red clover/Dactylis. Two years of turnips (in winter) and corn (in summer) 2. Every year turnips (in winter) and corn (in summer). Fertilizer treatments: a) 300 Kg of nitrogen/ha to turnips and corn (600 Kg/ha/year). b) Without nitrogen. The pasture was divided in two parts: in the first one, the cuttings were composted and recucled to the corresponding crops of turnip and corn; in the second part, the cuttings were not returned. |
