5954. Rosell, R.A., R. Martinez, K. Sommer and R. Miranda. 1982. Relationship of crop rotation and nitrogen availability for wheat in semiarid Argentina.. Plant Nutrition 2:551.
A sequence of small grains, annual natural pasture with grazing and a short (3 months) summer-fall fallowing showed low productivity when compared with a sequence of continuous grain with a long (6 months) fallowing. Wheat yields, number of ears per surface area and total nitrogen uptake were two times higher with long fallowing. Fertilizers are rarely used. Long-term average yields are in the order of 1.2 tons per hectare.
