Think of them as deposits in a soil fertility bank account. Most of these nutrients are tied up in long-term investments, in the form of organic matter. But a portion of the account is available for withdrawal. Assuming a soil is relatively fertile, the long-term goal is to maintain an approximately constant balance in the account, rather than to increase or decrease nutrient storage. As crops are removed, nutrients are withdrawn or exported from the system. As legumes, manures, composts, or other amendments are added to the soil, the nutrient bank balance increases.

Using other cultural practices with rotation can be the key to successfully controlling some pathogens. For example, after rotating land out of tomatoes to reduce pathogen populations, staking and mulching the subsequent tomato crop minimizes the potential for pathogen propagules remaining in the soil to disperse up onto the tomato plants. For a similar reason, deeply burying infested crop debris and pathogen survival structures by moldboard plowing reduces disease incidence. For this to work, the residue must be buried deeply enough that it is not pulled back up during seedbed preparation and cultivation.

Beneficial microorganisms stimulated include myxobacteria and Streptomyces.
