How often should soil be tested for nutrient levels?

Testing soil for nutrient levels is crucial for effective nutrient management in agriculture. Every 3-4 years is recommended because it allows for monitoring changes in soil fertility and nutrient availability, which can be influenced by factors such as crop rotation, manure applications, and environmental conditions. This frequency helps farmers adjust their nutrient management strategies accordingly, ensuring that crops receive the appropriate levels of nutrients for optimal growth while also minimizing the risk of nutrient runoff and environmental impact.

Regular testing at this interval enables proactive management rather than reactive responses to deficiencies, which can sometimes take longer to rectify and may affect crop yield and health. It also aligns with agricultural best practices that support soil health and sustainable farming by ensuring nutrients are applied efficiently and effectively.
