▷ Fertilization techniques of the milpa crop

The price ranges of inorganic fertilizers and pesticides have risen due to the existing geopolitical conditions. How extensive will they continue to be at that level? Will they go even better? How a lot of corn and bean farmers in milpa have stopped or lowered fertilization for this purpose? I don’t know the answers to the concerns, but they do not have to be flattering.

Any destructive adjust in the crop will have an influence on the country’s food stuff protection, due to the fact corn and beans are the diet program that delivers energy and protein to a substantial sector of the rural populace, without the need of neglecting the present desire for processed solutions of these grains in the country. city parts the zones. There are choices and procedures to tackle the challenge of substantial procurement fees.

The bean, as a legume, is regarded to kind a symbiosis with soil germs called rhizobia, which repair atmospheric nitrogen. In the nodules formed on the roots of the bean the symbiosis functions beautifully, the rhizobia enzymatically take care of the atmospheric nitrogen and give it free of charge to the bean this in switch, by returning the reward, delivers the natural and organic substances essential for bacterial growth. But not only is this obtained, in the milpa procedure of corn and red beans, the latter also gains from the bacterial nitrogen fastened by the atmosphere.

We have verified this in our investigations, thus confirming what Mexican and Brazilian scientists, bean farmers like us, have confirmed in their scientific publications.

Very nicely, and why not use what is presently recognised? It is by now occurring normally, mainly because rhizobia exists in our soil. On the other hand, this purely natural action ought to enhance and enhance to be helpful, and for this it is necessary to incorporate rhizobia to the crop. As did?

For reasons of place, I are unable to give aspects of our contribution in this regard. In summary, the technique was as follows: on the a person hand, the compost was acquired from agricultural residues, by suggests of compelled aeration by mechanical turning the rhizobes, on the other hand, formerly isolated from bean nodules obtained from the cultivation in milpa of Sacatepéquez and Jutiapa, were cultivated in a sterile society medium of appropriate composition, positioned in bioreactors operated at consistent and managed temperature and aeration. Then the suspension obtained from the rhizobia was extra by spraying to the compost in a belt shaker to favor a homogeneous combination. The enriched compost, as it were, was introduced to the discipline and the farmer extra a quantity of it when sowing the bean seeds. The outcomes have been thriving. The produce of both equally products in the plots enriched with rhizobia was, on the a single hand, substantially larger than in plots with out fertilization of any kind, and on the other hand, to our gratification, a a little reduce produce than that received with inorganic fertilization.

Trials have to continue, not only by growing the exam websites, but also by escalating the isolated rhizobia strains, in purchase to have, in the upcoming, a strong and productive bacterial inoculum, agent of the possible that exists in the place, considering that the rhizobia are incredibly distinct as to the host plant. These that infect beans, for illustration, do not infect soy, one more legume, and vice versa.

However, as frequently comes about in our lands, there is a deficiency of money to carry on the investigation.
