Policy Summary

This paper explores soil health and its relationship to crop health and pest management, as strengthened by cultural methods such as crop fertilization. Farming practices involving excessive use of inorganic fertilizers can cause nutrient imbalances and lower pest resistance. With more research regarding the relationship between soil fertility and insect pest attack, we will be better placed to convert conventional systems of crop production to those that incorporate agroecological strategies to optimize soil organic fertilization, crop diversity management, and more natural systems of pest regulation without incurring yield penalties.
