Green Manure Addition to Soil Increases Grain Zinc Concentration in Bread Wheat

摘要: Zinc (Zn) deficiency is a major problem for many people living on wheat-based diets. Here, we explored whether addition of green manure red clover and sunflower to calcareous soil or inoculating non-indigenous arbuscular mycorrhizal fungal (AMF) strain may increase grain Zn concentration in bread wheat. For this purpose performed multifactorial pot experiment, which the effects two manures (red clover, sunflower), ZnSO4 application, γ-irradiation (elimination naturally occurring AMF), AMF inoculation were tested. Both labeled with 65Zn radiotracer record recoveries aboveground plant biomass. Application fertilizer increased from 20 39 mg kg−1 sole raised 31 kg−1. Adding together even further 54 Mixing mobilized additional 48 µg (kg soil)−1 transfer biomass, compared total 132 taken up plain when neither nor applied. Green amendments also DTPA-extractable soil. Inoculating did not uptake. The study thus showed that organic matter can contribute better utilization stocked micronutrients, thereby reduce any need external inputs.
