Yes. By combining scientific advancements and on-farm sensibilities, dairy farmers continually look for new ways to be sustainable. Examples of sustainable farming practices include crop rotation to mitigate weeds and improve soil quality, the introduction of beneficial insects to control harmful pests, no-tillage or reduced tillage crop farming for soil and fuel conservation, and the use of new products with enhanced environmental benefits. Today, approximately 41 percent of crop land is cultivated using conservation tillage techniques that leave at least 30 percent of the previous crop residue after planting. This reduces erosion, retains soil moisture and conserves fuel.
