Cover crops[/h] 5 out of 5 (based on 3 reviews)




After the harvest season is over, it is time to think about keeping the land alive, protected and well nourished. To achieve this, it is best to use a technique known as cover cropping. 2-cover-crop-seed-hand-Large-484x664.jpg

Cover crops are typically composed of nitrogen-fixing plants known as legumes, such as beans, peas, and clovers *. Nitrogen-fixing plants contain a type of bacteria known as rhizobia in the root nodes. The rhizobium can convert atmospheric N2 into a plant assimilable form, ammonium (NH3 + H + → NH4 +), using the enzyme nitrogenase. 3-cover-crop-rhizobium-root-nodules-gettyimages-Large-664x648.jpg

The rhizobium inhabits the root nodes and returns atmospheric nitrogen to the rhizosphere, transforming it into a form of nitrogen that plants can assimilate.


In addition to the obvious benefits of nitrogen fixation in a plant-assimilable form, cover crops offer many other advantages. Living soil is in better condition when it maintains a continuous exchange with plants. The roots create structure and help maintain and protect the top layer of the soil. In many respects, the roots are the center of life in the soil. Mycorrhizae are fungal structures that grow in symbiosis with the roots of plants, creating a mutual exchange. These beneficial bacteria develop most favorably in the presence of the roots. The place where this exchange takes place is called the rhizosphere and is the narrow strip of land that receives the direct effect of the plant's secretions.Beneficial organisms feed on the shed cells of plants, as well as the proteins and sugars released by the roots, known as exudates. 4-cover-crop-seed-start-Large-664x454.jpg

Plants can play an important role in creating a biological balance in the earth, favoring organisms that prefer exudate food. The plant will feed the microbes that can better mineralize the nutrients it needs. This exchange promotes diversity and balance, and favors many varieties of organisms that have specialized functions that activate nutrients in the soil. 5-cover-crop-growing-Large-664x633.jpg

The cover crop is vital for the natural reintroduction of nitrogen into the soil in an assimilable form for plants through the use of symbiotic (mutual) associations with nitrogen-fixing bacteria (rhizobia).


Planting a cover crop helps the land's natural and economic cycle to prosper in the way that nature has evolved to do so. The top layer of living soil is protected from the sun by the plant's foliage, and the roots will contribute to the development of a healthy, nutritious network in the soil. The structure of the earth will return to a state of equilibrium that will be very beneficial at the time of planting, in spring. HSO-COVER.CROPPING-Large-e1418742473327-373x664.jpg

By mulching the cover crop, the biodiversity and soil structure created throughout the winter is preserved. Tillage destroys fungi that have grown in the soil, harms worms, and creates unbalanced concentrations of bacteria. However, tillage can be good for loosening and mixing soil, air, and matter. At Humboldt Seed Organization we believe that tillage is only suitable for initially decompressing the soil and mixing it with amendments and compounds rich in organic and biological matter.

Cover crops protect living soil from the elements and create a structure that contributes to the creation of a nutritious and healthy web in the soil.


For mulching, just add some compost or chicken manure evenly over the top of the cover crop. Next, the cardboard surface must be covered and compacted by stepping on it. It is best to do it between late winter and early spring, to be able to plant in late spring. Once the surface is covered, the cover crop plants will begin to decompose and contribute biologically to the soil. Mycorrhizae will continue to be present on the roots and can spread to the surrounding soil. Bacteria and fungi will eliminate the nitrogen-fixing roots, keeping the nitrogen in the soil in an assimilable form for plants. Tillage could release much of that nitrogen into the atmosphere.The mycelial fungi will remain unchanged and will keep the soil's nutrient network balanced and well structured. The worms will feed and grow smoothly, producing nutritious vermicompost for the plant. Legume-cover-Crop-664x373.jpg
