Indian Head Long Term Crop Rotations: Indian Head Saskatchewan.

Lafond, G.P., Campbell, C.A., Lemke, R.L., May, W.E., and Holzapfel, C.B. (2012). "Indian Head Long Term Crop Rotations: Indian Head Saskatchewan.", Prairie Soils and Crops, 5, pp. 42-50.


The Indian Head Long-Term Crop Rotations, established in 1957, consisted of nine different spring wheat based rotations. The rotations studied the effects of nitrogen and phosphorus fertilizer application, legume green manure crops, forage crops, different frequencies of fallow and straw removal. The study was converted from conventionaltillage to no-till in 1990. Applying fertilizers based on soil test recommendations, extending crop rotations and including green manure or hay crops and using no-till all increased grain yield, N and P uptake, soil organic matter content and soil quality, and enhanced nutrient cycling. The accumulation of nitrates in the soil can be greatly minimized when recommended rates of nitrogen are used in combination with continuous cropping. Annual straw removal during the wheat phase did not reduce soil organic matter or grain yields relative to a comparable rotation with straw retained. This suggests that some crop residues may be used for industrial purposes without detrimental effects on soil quality.
