What is a common purpose of soil testing?

A common purpose of soil testing is to assess nutrient needs, which is crucial for effective crop management. Soil tests provide valuable information about the nutrient availability in the soil, including essential elements such as nitrogen, phosphorus, potassium, and micronutrients. By understanding the nutrient profile of the soil, farmers and agronomists can make informed decisions on fertilization and soil amendments, ensuring that plants receive the proper nutrients necessary for optimal growth and yield.

This information also helps in preventing over-fertilization, which can lead to environmental problems such as nutrient runoff and soil degradation. Therefore, soil testing plays a critical role in sustainable agriculture by promoting the efficient use of nutrients tailored to the specific conditions and needs of the soil and crops being grown.
