Green manure: the SPA of the earth!

Almost everyone knows what a fertilizer is, but few people know when and how much to use and to complicate matters, even more, there are many different types, and the information we get from manufacturers can be significantly reduced, leaving us in doubt as to how and how to use it — frequency of use and the recommended amount for each plant.

We usually find in garden stores, earthworm humus, castor cake, bone meal, bull-tanned manure or liquid fertilizers, nitrogen, phosphorus, and potassium-based chemical preparations, or granules such as urea. Lawns. However, the mode of use for each of them is different and needs to be prescribed precisely, as too much can damage the crop.

Green manure is the name given to the cultivation of legumes such as beans to reincorporate nutrients into the soil and generate mulch, which in turn will protect the land from the sun’s rays and the impact of rainfall (solar and water erosion) and also, create a more excellent circulation of chemical elements, especially nitrogen. This is done through the exchange in the roots, by the metabolic action of bacteria, fungi, and microorganisms.

These beneficial soil agents act as carriers of tiny nitrogen molecules, improving the availability of nutrients to plants, helping them in biochemical exchanges between mineral salts through ions and cations, improving their health.

Improvement in drainage and maintenance of moisture in deep soil layers occurs through the action of its downward-growing pivoting roots, redistributing fertility to the deepest layers. There are many types of legumes, such as guan du beans ( Cajanus cajan ), in the photo that opens this post, a very fast-growing tree that allows intercropping ( different synchronized crops ) offering for new plants that are at your disposal. Foot, reliable sun protection at the beginning of cultivation and moisture after incorporation. Guandu beans can also be used to partially shade new growing seedlings, facilitating root penetration in compacted soils.

Other legumes widely used in green manure are mucuna ( Mucuna aterrima or M. Pruriens ), crotalaria ( Crotalária ochroleuca, spectábilis, juncea or Pauline ), the latter two being very aggressive. If not properly managed (controlled) can invade the whole terrain, so caution and caution are recommended when making this type of fertilizer since they are exotic species and if deployed without proper control can settle competing with native and harming other cultures.

In general, green manure brings an excellent result because it is natural and affordable. It also allows a break and time between production crops, thus ensuring the control of invasive plants and recurrent pests.

If you can’t find seeds from these plants where you live, you can use any bean, even our old everyday acquaintance, black or brown beans, depending on where you live, one or the other is most commonly used. One kilogram will allow you to plant more than 100 m2 and if soaked the night before, it will germinate even faster. And don’t forget, at the sign of the first flowering, turn the roots around and let the plant dry out and re-enter the soil, which should take about a month and a half depending on temperature and humidity conditions.

Once reincorporated proceed with the plan for planting corn, squash, arugula, lettuce, kale, tomato and you will see how your land will be better!

If you don’t have a large garden or garden, you can make green manure with a small black or brown bean. They are smaller and fit in a vase. Another option is to use natural fertilizers that do not harm plants or pose a risk to children and animals, even if used above the right size.

One tablespoon of natural manure per small pot – about 300 ml should suffice. When it comes to manure or earthworm humus, it may take up to 20 days for the plant to feel the effects of the new nutrients, which take a few weeks to incorporate.

To get an idea of ​​fertilizer volume, keep in mind that…… The more matter is harvested or taken from the ground, the more water, the more nutrients, the more biomass is lost. Fertilization is their replacement process. We have often made from the field before our arrival, in a particular crop or even in a burn. So all we can do is give the land a VIP treatment, a harvest for itself to compose itself.
