CORN-SOY GRAIN CONVENTIONAL ROTATION

Model Dairy Farm Herd Dynamics: - 65 lactating cows - 10 dry cows - 64 young stock (birth to 24 months)

Goals: - Forage and Feed Sustainability - Maximize Forage Use - Minimize Purchased Feed

Linking with dairy cropping systems: - Use yield and forage / grain quality data from our cropping systems to develop base rations .

- Calculate forage and feed inventory for all animal groups in a given year.

- Use the 2001 NRC model and the CPM model to predict animal performance.

• Shallow disk and aeration manure application strategies can provide nutrient management benefits of incorporation into soil without the soil erosion caused by tillage.

• Shallow disk injection reduces ammonia emissions by about 95%, but some of this benefit is offset by greater emission of the greenhouse gas, nitrous oxide.

Insect & Slug Management: • Diversity in time and space should help interrupt insect pest life cycles and promote natural enemies. • Slugs are a challenging pest in no-till systems - we are using this experiment to learn about slug ecology and management.
