How can a farmer grow a good and healthy crop?

How can a farmer grow a good and healthy crop? After deciding what to grow, farmers often till the land by loosening the soil and mixing in fertilizers, which are nutrient rich. Then, they sow seeds or plant seedlings. When the crops are growing, farmers must water (or rely on rainfall), weed and kill crop pests.
