Soil Nutrient Stratification in Long-term Sustainable Cropping Systems Research Study

A tillage by rotation study evaluated after 11 years to determine if the use of no-till had led to nutrient stratification in the plots. The results of this study indicate that nutrients did become stratified, but the effect was minor.

IPNI-2006-CAN-AB23

The study is located on Black Chernozem with a moderately fine clay loam texture. After 12 years of cropping to a Canola-Barley-Peas-Wheat (CBPW) rotation, using both conventional and no-till seeding systems, soil samples at the 0-7. 5 and 7. 5 – 15 cm depths were collected in the fall of 2006. These samples would be analyzed for N, P, K and S by ALS Labs to determine the impact of tillage on nutrient stratification. Values for pH have already been determined. Read more

Stratification of pH and Nutrients in Two Surface Layers of the Three Hills Long-Term Cropping System Plots, 2006 A tillage by rotation study at Three Hills, Alberta, was evaluated after 11 years to determine if the use of no-till had led to nutrient stratification in the plots. The original study involved tilled versus no-till comparisons, and a number of crop rotations. The soil is a Solonetzic Black Chernozem, with a clay-loam texture.
