Weed control by mulching films and textiles

In line with the “Farm to Fork” program, Arrigoni has developed several completely “green,” sustainable solutions, both films and textiles, specifically to control weeds underneath the canopy, thus providing a valid alternative to man-made chemicals.

In fact, the European “Farm to Fork” program is very clear on this subject and its provisions include: a 50% reduction in the use of plant protection products in farming by 2030; the halving of the loss of nutrients from the soil to maintain its fertility; and the conversion of 25% of agricultural land to organic crops by 2030.

Arrigoni offers mulching films and Agritela mulching textiles to combat weed growth.

Arrigoni, the group which leads the way in the design and production of agro textiles for the farming sector, has come up with a variety of solutions, depending on the type of terrain: mulching films, which simply inhibit weed seeds and growth due to their intrinsic characteristics; and Agritela mulching textiles, which also enable a good flow of air to pass, permitting gaseous exchanges with the soil to keep it oxygenated. This not only supports the microbial flora but also reduces standing water and the onset of root diseases. This factor is particularly important in orchards which implement super-intensive growing methods, where heavy irrigation is adopted.

“In general,” Arrigoni agronomist Milena Poledica explained, “mulching films and textiles prevent the germination of weed seeds, a process triggered by light and other factors such as moisture. Their high shading factor of 100% prevents the passage of all short UV/PAR/IR radiation. The blocking of UV radiation stops seeds germinating, while the blocking of PAR prevents photosynthesis. This effect replaces both the anti-germination action of herbicides and the blocking of photosynthesis and respiration provided by other types of plant protection products. Therefore, in the case of mulching textiles quality and density of weave are fundamental for effective weed control.”

Moreover, orchards with a lifetime of decades require a long-lasting mulching solution. Arrigoni textiles are the most durable (up to 20,000 Newton-metres for Agritela), since they are tough and resistant to mechanical procedures or the transit of vehicles and people.

Another very important factor is color. Black is the color with the greatest resistance to UV radiation and is therefore the most durable. It is no coincidence that in the past it was the most widely used. However, to meet some farming needs such as the reflection of light and the reduction of soil temperature, today mulching materials have evolved to be two-color, black and white. This change has taken place for both mulching films and textiles. Therefore, the benefits of a two-color mulching textile (such as Arrigoni Agritela Black & White) are mulching, the assurance of gaseous exchanges, and the reflection of light.

“The research we have conducted in recent years,” concluded CEO Paolo Arrigoni,” has shown yet again that more and more sustainable and green farming is possible, even in a very complex and competitive area like fruit growing.”
