Types of Crops:________________________________________________________________________ _____________________________________________________________________________________ Type of Crop Roots Leaves Fruits (not tree fruits) Flowers Legumes Example of crop rotation:____ The first year you plant a crop harvested for its root. The following year you plant a crop harvested for its leaves. Why Rotate Crops? Monoculture:__________________________________________________________________________ _____________________________________________________________________________________ Problems that were encountered when the same type of plant was grown in the field year after year 1) 1 Some of the nutrients will be depleted more than others based on the needs of that plant 2) The soil may become contaminated by large amounts of pests that attack that particular crops Choosing Crops Crop choice is based on… Environmental 1)____________________ 2)____________________ 3)___________________ Financial 1)_____________________________________________________________________ 2)____________________________________________________________________________ Crop Rotation Key Points in the System -____________________________________________________________________________________ _____________________________________________________________________________________ _____________________________________________________________________________________ - Crops may be rotated every year or at different times in the growing season - Many crop rotations will include a legume. Remember legumes have a symbiotic relationship with bacteria that fix nitrogen = Increased nitrogen in the soil for the next crop Examples of Crop Rotation -____________________________________________________________________________________ How Crop Rotation Works Four Field Rotation:_____________________________________________________________________ _____________________________________________________________________________________ Crop Field A Field B Field C Field D Crop Rotations with Animals _____________________________________________________________________________________ _____________________________________________________________________________________ _____________________________________________________________________________________ Second year (After the manure has had a chance to decompose) plants are grown on the cattle fertilized field Benefits of Crop Rotation: 1)___________________________________________________________________________________ _____________________________________________________________________________________ _____________________________________________________________________________________ -____________________________________________________________________________________ _____________________________________________________________________________________ 2) The number of pests that attack each crop is reduced. 3) Farmers can grow more than one successful crop per year = Increased crop yields (10-25%) Risk of Crop Rotation -____________________________________________________________________________________ _____________________________________________________________________________________ _____________________________________________________________________________________ -____________________________________________________________________________________ _____________________________________________________________________________________ Overall the benefits out way the risks Questions: 1-6 1) Plan a 4 year crop rotation for radishes, cauliflower, tomatoes, and kale Year 1 Year 2 Year 3 Field A Field B Field C Field D 2) What reasons would a farmer have to avoid crop rotation 3) In a paragraph, explain the benefits of crop rotation to the farmer.
