The article explores how micronutrients in soil are extracted and made available for plants. It looks at different forms of micronutrients and how they are affected by natural conditions and human activities. The study focuses on removing micronutrients from different parts of the soil and how plants absorb them. Different extraction methods were used to measure levels of Co, Cu, Fe, Mn, Ni, and Zn in the soil. The researchers found that the type of extracting solution and concentration of extractant can affect the removal of micronutrients. They also discovered that certain salts can extract more Fe, Mn, and Zn from the soil compared to others. Additionally, the study showed that higher concentrations of extractants can release more trace metals from the soil.
