Listen now:
In this episode:
- Boron is the nutrient with the narrowest range between sufficient and toxic
- Annual crops tend to be less sensitive to chloride toxicity, while perennial crops tend to be more sensitive to Cl
- Iron toxicity, although not common in US soils, can occur when soil pH decreases and the acidity in the soil increases
- In some situations, the use of potassium chloride can increase manganese's availability in the soil, leading to Mn toxicity
