What does the term "fertility management" encompass?

The term "fertility management" primarily involves strategies and practices aimed at maintaining and improving the nutrient levels in the soil to promote healthy plant growth and maximize crop yield. This includes understanding the three primary macronutrients (nitrogen, phosphorus, and potassium), secondary nutrients, and micronutrients that crops require. Effective fertility management can involve soil testing to determine nutrient levels, application of fertilizers at appropriate rates and times, and using organic amendments to enhance soil fertility. By focusing on maintaining optimal nutrient levels, farmers can ensure that their crops receive the necessary resources for growth, which is vital for both productivity and sustainability in agricultural practices.
