Nature can reduce pesticide use, environment impact

Farmers around the world are turning to nature to help them reduce pesticide use, environmental impact and, subsequently, and in some cases, increasing yields.

Specifically, they're attracting birds and other vertebrates, which keep pests and other invasive species away from their crops. The study, led by Michigan State University and appearing in the current issue of...

In-depth mineral review provides foundational resource for dairy scientists

Life is dependent on minerals. Accordingly, the diets of animals must contain certain minerals in both large amounts, via marcrominerals, and small amounts, via microminerals. In a thorough and wide-ranging review published in the Journal of Dairy Science®, Jesse Goff, DVM, PhD, professor and Anderson Chair in Veterinary Medicine at Iowa State University, examined necessary...
