Currently, we seek to produce more using sustainable management techniques that preserve the environment, in particular soil characteristics, nutrients and natural microbiology.
It is known that the use of cover crops is one of the fundamental principles for maintaining the sustainability of agricultural systems, highlighting the Direct Planting System as one of the most conservationist and environmentally correct agricultural techniques that exists. To achieve this result, we depend on proper planning and execution of cultural treatments, which must be started at the end of the season, already thinking about the subsequent season.
Coverage mixes, also known as polycultures, are an intelligent association of species with complementary agronomic functions. They are capable of transforming the soil between harvests, naturally renewing nutrients and improving physical, chemical and biological aspects of the soil. The main benefits of polycultures are:
>High production of plant biomass;
>High nutrient cycling;
>Improvement in soil aggregation and structuring;
>Soil decompression and aeration;
>Increased biological activity;
> Increased carbon;
>Increased water infiltration and soil water storage.
Each cover plant has its characteristics, so we can use species with fast growth and prolonged cover. In the dynamics of the coverage mix, we must respect some aspects, such as: synergism and complementarity between species, functions of each plant in the mix, cycle of each plant and C/N ratio (carbon/nitrogen), among other aspects.
When choosing the mix for his area, the producer must choose species that meet his needs (pre-wheat mix, corn, soy, grazing, etc.) and that have good development in the region. Among the service plants most used in mixes, we have mixtures of grasses, legumes, crucifers and polygonaceae, each of which fulfills a certain role in polyculture. Always seek out a specialist professional for an accurate recommendation on the type of cover mix for the agricultural system.
Given the above, knowing the countless possibilities for improvements in production systems aimed at preserving soil, water and microbiology.
We know that the world lives in constant transformation. In recent years, the breadth of the concept of sustainability has been changing, becoming increasingly linked to preservation and increased diversity, aiming at a new understanding of production seeking balance.
In this context, mixes of cover crops fit as a tool that increases the biological diversity of the soil, improves the physical and nutritional characteristics and preserves and multiplies the microbiota.
