Caring for Crops (weeding, fertilizer, pest control)

Using manure as a fertilizer to help crops grow
Rotating Crops - different crops are planted in a regular sequence so that a crop that leaches the soil of one kind of nutrient is followed during the next growing season by a crop that returns that nutrient to the soil
