The effects of mineral and organic fertilization on the contents of Fe, Cu, Zn, Mn, B and Mo in soil and in the soil solution as well as on availability of these elements for crops were investigated in the long-term field trial. The highest contents of Zn, Fe, Mn and Cu in soil and soil solution were observed in the treatment with the lowest pH (NPK). In this same combination the content of B and Mo was the lowest. The concentration of Zn, B and Fe in the soil solution significantly increased under farmyard manure application. Liming significantly decreased contents extractable by 1 mol/L HCl forms of Mn and Zn and significantly increase the content of Mo in the soil. Regardless of fertilization applied, microelement concentrations in the soil solution are sufficient for fulfilling nutritional needs of plants cultivated during the trial.

Deep Plowing

Deep plowing (DP) has been investigated as a possible ameliorative procedure for Solonetzic soils, but the long-term effects of DP on soil properties are not known. Soil sampling to determine the long-lasting effects of DP on some soil chemical properties and crop yields was conducted at four sites with Solonetzic soils in east-central Alberta. The soils had been deep plowed 11–29 yr prior to sampling. Compared to adjacent unplowed (check) treatments, DP resulted in significant improvements in soil chemical properties at most of the sites. The sodium adsorption ratio (SAR) of the AB horizon (12- or 15- to 30-cm depth) was lower after DP at all four sites. Extractable and soluble Ca increased in the Ap horizon (0–12 cm) of DP soils, whereas extractable Na decreased in the Ap or AB horizons at three sites. The pH of the Ap horizon increased from acidic to neutral at three sites, while EC of the Ap horizon decreased at two sites. Crop yield increased due to DP at the three sites where yields were measured. The results indicate a long-term amelioration of Solonetzic soils by DP.
