One of the first questions that you will have to face having to "prepare" the land for organic cultivation is to have to make the enrichment using only organic substances and without being able in any way to resort to synthetic products. The fertilizing phase is of fundamental importance to provide the nourishment necessary to guarantee the correct growth of the plants. The soil, after having been plowed, will be fertilized with fresh or dry manure. The organic substance added in this form will then be degraded by the microorganisms present in the soil that will release the nutrients in a form that can be assimilated by the plants. If decomposition is only partial, the soil will be richer in terms of humus. In addition to this you can then use other products available on the market and allowed by this type of cultivation. The products in question are: composting soil (obtained by decomposing organic vegetable material), dried blood (produced in slaughterhouses) or wood ashes. This treatment will be carried out at the end of winter to prepare the ground for sowing. Notwithstanding that manure remains the excellent fertilizer for cultivation, it is not always possible, however, to obtain it. As an alternative to it, you can use the so-called "pelleted manure" which is generally sold in bags ranging from 5 to 25 kilograms. This type of fertilizer brings the necessary nutrients to the soil helping to restore its ideal pH. It is obtained by processing animal dejections which are subjected to a process of humification by decomposer bacteria to be reduced to a form that is more assimilable by plants. After that the manure will be dried and processed. In this way a slow release natural fertilizer is produced ready to be spread on the ground before digging. Another very effective fertilizer that you can use in organic farming is obtained from the so-called "guano deposits" formed by the accumulation of manure and the carcasses of numerous sea birds over the centuries.List of fertilizers allowed in organic farming

However, there is a very precise regulation on the matter which establishes, by drawing up a special list, which fertilizers are permitted in the biological field. Among these we find the Wool Cascami, the peat, a humic extract deriving from the vegetation water of the olives, hydrolyzed animal epithelium and many others. Liquid fertilizers made available on the market and allowed in organic farming can also be used, as they derive from organic substances, which you will certainly find very comfortable and practical.

Organic farming fertilizers: the green manure technique

You can also use the green manure technique, which is quite simple, but very useful for enrichment through the use of vegetable substances coming from crops previously cultivated in the same land. The plants most used in this technique are undoubtedly the legumes which are able to provide the soil with a significant nitrogen supply. These plants, in fact, are able to carry out atmospheric nitrogen fixation thanks to the symbiontic association they hold with bacteria belonging to the genus Rhizobium. These bacteria transform the gaseous nitrogen present in the air into a form easily assimilable by plants. To be able to do this, however, they must necessarily colonize a guest and the host in question is precisely the legumes. Among these you can opt for peas, beans, lupins, clover etc. Not to be neglected is the fact that it is a rather inexpensive technique that makes it possible to make the land suitable for any type of plant you want to cultivate even if, unfortunately, for the period in which it must be performed, it will force you to renounce the harvest of the fruits. In fact, you will have to cut the plants during the flowering period, when they are richer in nitrogen, let them dry on the surface and then bury them at a depth of 10-15 centimeters. Use this technique sowing legumes in alternation with particularly avid nitrogen crops that will surely benefit from them.
Well now you just need to get down to work and cultivate in a respectful and natural way all the "green treasures" that you will be able to place in your garden, sure you have also contributed to a better future for the planet.

    I am sorry, that has interfered... At me a similar situation. Is ready to help.

    Obviously you were mistaken...

    I apologise, but, in my opinion, you are not right. I am assured. I suggest it to discuss.
