Plant nutrients are essential substances that plants need to grow and thrive. These nutrients are typically divided into two categories: macronutrients and micronutrients. Macronutrients include elements like nitrogen, phosphorus, and potassium, which are required in larger amounts, while micronutrients such as iron, manganese, and zinc are needed in smaller quantities but are still vital for plant health. Plants absorb these nutrients from the soil through their roots. The availability of nutrients can be influenced by factors like soil composition, pH levels, and moisture. Proper nutrient management is crucial for agriculture and gardening, as it helps ensure that plants receive the right balance for optimal growth and productivity.
