Micronutrients are essential nutrients required in small quantities by plants for their proper growth and development. They include elements such as zinc, boron, iron, manganese, copper, and molybdenum. These nutrients are likely to be deficient in soils with low pH levels because acidic conditions in the soil limit the availability of micronutrients to the plants. This means that even though these nutrients may be present in the soil, the plant cannot access them in sufficient quantities for their growth and development. Additionally, the use of high-phosphate fertilizers and excessive irrigation can also cause micronutrient deficiencies in plants. Soils with high organic matter content or fine texture are not necessarily deficient in micronutrients. In fact, organic matter can contribute to the availability of micronutrients in the soil, while fine texture soils generally have a higher nutrient holding capacity. Cleared virgin forest soils can also have varying levels of micronutrients depending on the soil type and the amount of weathering that has occurred.
