Phosphorus supports root and flower development.

Potassium enhances drought resistance and overall plant health.

Farmers should aim for balanced nutrient levels.

Recognizing Organic Matter Importance

Organic matter enhances soil fertility and structure.

It improves water retention and microbial activity.

Farmers should strive for at least 5% organic matter in their soil.

Utilizing Soil Test Recommendations

Soil tests often come with recommendations for amendments.

Following these recommendations can optimize crop production.

Farmers should consider soil tests as a roadmap for fertility management.

Regular testing helps track changes and adjust practices accordingly.
