Plants can absorb these nutrients only in certain forms, and organic fertilizers must be broken down by soil microbes first, a process called mineralization, which converts nutrients into forms ...
Cover crops retain soil and lessen erosion, along with green manures that add nutrients and organic matter, especially nitrogen. [76] Herbaceous layer: Plants that die back to the ground every winter, if cold enough. No woody stems. Many beneficial plants such as culinary and medicinal herbs are in this layer; whether annuals, biennials, or ...
A portion of organic matter is not mineralized and instead decomposed into stable organic matter that is denominated "humus". [1] The decomposition of organic compounds occurs at very different rates, depending on the nature of the compound. The ranking, from fast to slow rates, is: Sugars, starches, and simple proteins; Proteins ...

[31] [11] It is sometimes credited as being the most widely use organic fertilizer and by volume is the top organic amendment.
Anise hyssop is considered one of the premier plants for feeding pollinators.

Miscanthus giganteus - a perennial crop with high yields and high GHG mitigation potential. Perennial sunflower - a perennial oil and seedcrop developed through backcrossing genes with wild sunflower. Perennial grain - more extensive root systems allow for more efficient water and nutrient uptake, while reducing year-round erosion due to rain ...
