3070. Tanaka, D.L. and J.K. Aase. 1989. Influence of topsoil removal and fertilizer application on spring wheat yields.. Soil Sci. Soc. Am. J. 53:228-232.
In 3 of 5 years, soil removal treatments reduced spring wheat yields an average of 9, 28, and 45% for 0.06, 0.12, and 0.18 m soil removal treatments, respectively, over all fertilizer treatments. The data suggest that P was the most limiting nutrient and additions of N fertilizer without P resulted in small yield increases.

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.
