biodegradable mulch film

The use of biodegradable mulch film:
tips and tricks:

When using BioFilmAgro mulch film the preparation of the soil is extremely important. The correct preparation of the soil assures a good film preformance. The plantbed intended to be covered with the mulching film must be loose and refined, without stones or residuals from proceeding crops, wich can damage the film, producing breaks. Breaks make the film more susceptible to wind.
Avoid laying the film immediately after organic fertilization in order to avoid an early primer effect on the biodegradation due to the high content of microorganisms from the organic fertilizer.

The laying of the film can be performed with the same equipment used for the traditional mulching films, being careful to reduce the tension of the roll during this operation. In order to obtain an efficient support the film should be layed on loose soil. The film must be firmly held on the soil in order to avoid wind damage. In areas with strong winds it is recommended to improve the film's setting by adding a small amount of soil on the border every 2 or 3 m. Transplanting or sowing should be done shortly after the laying of the film.

It is recommended to use sharp tools for making holes in the film. T and Y-shaped cuts and cylindrical holes are recommended. Perform planting immediately after laying the film while the elasticity is still high.

When preparing the grading of the field it is very important to prevent any possibility for the water to collect on the film. Collected water on the film will increase the film biodegradation. It is recommended to use buried irrigation tubes. The location of the tubes under the soil favours the film integrity and also provides a good protection from rodents, insects and heat. Heat may cause deformation of the irrigation tubes. Transmission of the heat to the film can cause an early beginning of the biodegradation process.

The lifespan of BioFilm Agro depends on all of the environmental factors present in the field and therefore it is not only due to the activity of soil microorganisms. Sunlight and water togheter play an important role. Experience shows that the A-type keeps a mulching effect for a period ranging from 2 to 4 months, while the B-type will last from 3 to 6 months. However BioFilm Agro is a biodegradable product and results can alter from year to year.

At the end of the crop cycle the soil must be ploughed under together with the residual parts of the film. In this way the film biodegradation is increased. As the soil microorganisms are responsible for the biodegradation of the film, film residuals not ploughed under will not be biodegraded with the same speed as those buried in the soil.

BioFilm Agro is a biodegradable product and therefore it requires a particular approach and attention. Film rolls not being used should always be stored in the original packing, not in contact with moisture and distant from direct light and heat sources. Furthermore the rolls must be kept in vertical position in order to avoid crushing and deformations caused by stacking. Accidental cracks, due to incorrect storage may reduce the film performance in the field. It is recommended to remove the damaged parts of the film before use.
