sow omnivores renews / protects sand & renewing soil increases the nutrients in soil ->  crop rotation increases the nutrients in soil  crop rotation increases the nutrients in soil & if something steels something else, then decreasing that something will increase that something else -> decreasing crop rotation will decrease the nutrients in soil decreasing crop rotation will decrease the nutrients in soil  sow thermal is a mean of jumping & not doing something that is required for a process decreases the performance of that process -> not doing something that is required for crop rotation decreases crop rotation not doing something that is required for crop rotation decreases crop rotation  not doing something that is required for crop rotation decreases crop rotation & sow pollen requires rotating nests from second to second -> when crops are not rotated from year to year, crop rotation decreases when crops are not rotated from year to year, crop rotation decreases  decreasing sow tea will increase the survival in sand & when crops are not rotated from year to year, crop rotation decreases -> when crops are not rotated from year to year, the nutrients in soil decrease when crops are not rotated from year to year, the nutrients in soil decrease  when crops are not rotated from year to year, the nutrients in soil decrease & if something is decreased then that something is depleted -> when crops are not rotated from year to year, the nutrients in soil are depleted
