Guide of implementation of the Multifunctional Landscapes
To help to that the biodiversity grows is one of the 6 commitments that from Syngenta we propose in our program of viability, The Good Growth Plan. By this we created the project Multifunctional Landscapes, that the possibility gives him to the producer of taking care of the diversity of pollenizers in its lot, producing with very little effort and low cost a more viable agriculture.
For its correct installation, recommendable that the refuges, that can at any time be installed of the year, are located in places within the field, thus avoiding it is wire fenced peripheral that limits with neighboring fields and ways of public use. A strip of 3 to 5 meters in width is sufficient not to interfere with the productive development.
Three steps exist to follow previous the opening of a biodiversity refuge. As first measurement, it is necessary to decide what area will be refuge and to interrupt in her the application of plant health products, since the fertilizers promote the growth of the dominant plants (many of which are weeds of cultures), that can suppress the growth of the grass with flowers visited by insects.
Secondly, we must allow the growth of the vegetation, avoiding you cut, applications, transit on the parcels and any other intervention that can alter the natural growth. Last, to execute the annual cut, that is advised to realise to 20 cm of the ground with the aim of diminishing the cover of grass. These cuts look for to eliminate the vegetation produced during the summer, the perennial grass and shrubs in the vegetation.
To avoid the transit of vehicles and the access of cattle they are other points to consider, since they can bring about negative effects on the biodiversity of the refuges. By this, the closing of the area of the refuge is suggested to manage to avoid the transit of vehicles and the access of the cattle, that can have negative effects on the biodiversity of the refuges. The most effective form to avoid the animal entrance is the installation of an electrical fencing.
Between the half-full end of the summer and of the autumn it is the time more recommended to install the biodiversity refuges, preferably, before it happens the first frost. If it is chosen to install during the spring, and in the chosen space there is vegetation with flowers, he is recommendable not to cut. Thus, the activity of the pollenizers and the production of seeds can continue their normal course. This equation modifies in case the perennial grass dominates the land: there it is necessary to cut to the vegetation anyone is the time of the year.
In case the vegetation of the chosen site to install the biodiversity refuge is dominated by plants that produce flowers and attract the pollenizers, the closing of the space will be able to be realised. Also it can eliminate the wished species and, if it has seeds, manually not eliminate them of the refuge to avoid his propagation. At the time of realising the cut, it is important to use that one that manages to adapt itself to the space, such as the desmalezadoras.
The machinery to realise the cut must be able to adapt itself to the space, such as the desmalezadoras or motoguada±as. After realising the cut, to a height among 15 and 20 centimeters, is necessary to run the vegetal material to avoid that this it interferes in the growth.
Although it hardly represents a low cost and a few hours the year, to consider the care and maintenance of the refuges is something of extreme importance. In the refuge, weed killers, fertilizers and insecticides are prohibited, and the transit of machineries must be reduced to the minimum. To do crossed periodic helps to detect and to remove species us nonwished (weeds, invading, ligneous plants).
