Bioavailability, Speciation, and Crop Responses to Copper, Zinc, and Boron Fertilization in South-Central Saskatchewan Soil

An appropriate fertilization strategy is essential for improving micronutrient supply, crop nutrition, yield and quality. Comparative effects of different application strategies fertilizer were evaluated in two contrasting sites/soils (upper slope Chernozem lower Solonetz) within a farm field located the Brown soil zone Saskatchewan, Canada. The study objective was to examine impact Cu, Zn, B on their mobility, bioavailability fate as well responses. broadcast, broadcast incorporation, seed row banding, foliar wheat, pea, canola, respectively. laid out randomized complete block design (RCBD) with four treatment replicates specific site. Crop biomass yields not significantly influenced by placement at both sites. Pea tissue Zn concentration (35.2 mg kg−1 grain 5.15 straw) increased incorporation sulfate Solonetz soil. Residual levels extractable available Cu 3.18 2.53 site banding sulfate. PRS™-probe supply (1.84 µm Cu/cm2) (1.18 Zn/cm2) higher corresponding Both chemical spectroscopic speciation revealed that carbonate associated dominant species are likely control these micronutrients under conditions.
