Web3 apr. 2024 · However, the availability of the metallic micronutrients zinc, manganese, copper, and iron increases as pH decreases. If the pH drops much below 5.5, the availability of manganese and aluminum increases to the point where they could become toxic to plants. Aluminum toxicity is a major concern in our acid soils. Factors Affecting … WebMicronutrient Nutrition. Through increased use of soil testing and plant analyses, micronutrient deficiencies have been verified in many soils. Some reasons limiting the incidental additions of micronutrients include: High-yield crop demands remove micronutrients from the soil. Increased use of high-analysis NPK fertilizers containing …
