What is stubble?

What Does stubble Mean

It is known as stubble to the residues and the remains that remain on the ground after mowing . Stubble is formed from the parts of the leaves and stems that fall to the surface after the crops are cut.

Stubble is important for soil protection . Although they are often thought of as nothing more than waste, they actually help fight erosion .
When managing land use, therefore, it is necessary to analyze how to manage stubble. The retention stover is key, but the amounts depend on the characteristics of the terrain and the region.

At a general level, it can be said that stubble contributes to water infiltration and minimizes the flow that is lost through evaporation. The stubble, thus, influence when defining the irrigation.
The cereal produce a higher amount of stover to that generated by oil plants . The barley and wheat are two of the species that favor the creation of an abundant level of stover.
In order to eliminate weeds and fertilize the soil with ash, it is common for farmers to resort to burning stubble . However, this practice favors desertification and can lead to fires out of control. That is why many experts discourage stubble from being burned.
In the past, when the general opinion favored the burning of stubble, the land was treated much less adequately to the requirements of agriculture. One of the measures to prevent this practice from leading to a fire consists of generating a footprint around the area, that is, along its perimeter, where the fire cannot continue to advance; however, this step should also be done with some technical knowledge to maximize field safety.
The direct seeding is a proposal that eliminates both stubble burning as the plow, so that exploits the conditions of the soil without altering it . For this, it is necessary to use a special machine that, with the help of blades, allows the seeds to be planted without giving the soil back. Although this entails a monetary investment and the reorganization of the sowing, it guarantees the health of the soil and in the long term makes the field more profitable; the "old way" only wears it down to a point where it is unusable.
Stubble can appear in different proportions. The better the yield of the corn , the greater its quantity. In numerical data, it is estimated that the residues that are released from sowing are around fifty percent of the dry weight of production. This volume of organic matter is considerable and, given that it can be used to obtain different benefits, continuing to support its elimination does not make sense at present.

We must not ignore the degree of pollution generated by its burning: it not only directly affects the properties of the soil, but also dirties the air and contributes to the greenhouse effect through the release of gases. This is accentuated by the combination of the rains (which usually appear at the time of the year in which it is harvested) and the action of human beings. Systematically incorporating the stubble into the soil gives it the minerals it needs for its nutrition, enhancing its health and fertility, something that also affects the flora and fauna of the place.
Los Rastrojos , finally, is the name which is known to a paramilitary group in Colombia . Also called Rondas Campesinas Populares ( RCP ), the Los Rastrojos group is dedicated to drug trafficking and seeks to control territorial strips.
