Spring: March 21 – June 20
The fields are prepared for planting crops
- Cows play a key role in nutrient recycling. They eat the plants; then their manure is used to fertilize the plants so that the farmers can grow healthy crops to feed the cows again.
Summer: June 21 – September 20
- Grass, clover and alfalfa are usually harvested every 30 to 40 days.
- The land is fertilized after each crop, and in drier regions it needs to be watered twice between crop rotations.
Fall: September 21 – December 20
Harvesting and maintenance
- Annual crops like corn are harvested in the fall. At this stage of growth they provide the best feed for dairy cows.
- Crops are planted to protect the soil over the winter months.
Winter: December 21 – March 20
- The winter months are used to plan for the next year’s growing season by reviewing the previous year’s crop failures and successes, and buying new equipment and supplies.
