The practice of organic farming includes the concept of non-processing and growth as by nature of wild herbs , without the use of any fertilizer or treatment of any kind, such as the classic copper. Plants enjoy excellent health without the use of chemistry, and produce with higher yields.
The importance of Spontaneous Herbs in permanent crops such as vineyards, olive groves and orchards in general, is fortunately increasingly recognized and many companies decide to hang the cutter “on the nail” in favor of very simple mowing.
Interaction of spontaneous herbs with permanent agricultural crops
- They do not compete with the root system of trees and shrubs because they operate at different levels, moreover the competition would take place only in the very short term, while in the medium-long term the spontaneous bring minerals cyclically thanks to their decomposition in the field.
- Spontaneous herbs make it possible not to lose minerals (which must then be replenished with external fertilizers), because with their roots they absorb them during the rains. Without them, with the soil worked and empty, the mineral salts are taken away with the rains (leaching).
- Thanks to their roots they allow greater water permeability , avoiding the classic phenomena of flooding and stagnation of processed soils , especially if clayey, which form an impermeable layer and then become hard as cement . The exact opposite of what is touted in the world of conventional agriculture.
- Wild herbs release sugar exudates into the soil (like all plants) through their roots, which nourish the microbial life of the soil in a balance that makes plants more healthy and resistant . A bit like what happens in our intestines, where the immune system is compromised when the bacterial flora is not adequate. Soil processing destroys this balance. Plants are less healthy and tend to get sick more easily.
- Spontaneous herbs help mitigate any pest infestations . In a worked field, where there is nothing but the main crop, pests can only concentrate and thrive on our crops. With the presence of the spontaneous the parasites tend to distribute themselves more, moreover they can arrive and prosper other predatory insects able to create equilibriums and not to require to intervene with specific treatments.
- Wild herbs: they help keep the soil moist , slowing water evaporation, a very useful phenomenon in summer. Furthermore, the spontaneous at night act as vapor condensers, allowing the infiltration of water into the soil and decreasing the humidity of the air that can help the classic fungal diseases.
- The spontaneous recall many small animals, birds, hedgehogs, toads, which bring further organic substance in our field thanks to their droppings.
- Of the spontaneous we often find legumes, which fix nitrogen in the soil .
A new agriculture that does not pollute the land
So why waste time, effort, money, or even pollute, to do something that even damages our crops?
Healthy crops can exist only on healthy soil , otherwise it will be necessary to intervene continuously with external interventions such as fertilizers and various treatments.
A couple of cuttings a year could already be more than enough to manage any vineyard or orchard. Indeed, in the cases of land devastated by processing, it would be useful to sow mix of spontaneous crops including perennial legumes such as dwarf clover or alfalfa . Who tells us that the land must be worked by force, perhaps aims more to sell machinery and chemical products than to a healthy agriculture.
