The primary sector in tropical and subtropical countries is now booming and, alongside more traditional crops, the production of pomegranate and small fruits (raspberry, strawberry, blueberry) is also developing strongly. However, farmers in these countries are increasingly faced with sudden and violent climate change, often with unpredictable consequences, due to the gradual rise in global temperatures. Arrigoni, a leading company in the production of agrotexiles, gave impetus to the practical Net House system, a hybrid solution between greenhouse and open field, which offers both agronomic advantages, with better temperature control, and also savings, with a significant reduction in installation costs compared to greenhouses. For hotter and more unstable climates, the most effective solution is ROBUXTA®, designed precisely for use on tensile structures (such as nets) and thanks to its abrasion resistance.

Climate change is now a reality that all agricultural areas on the planet must face, regardless of latitude and crops. The latest IPCC (Intergovernmental Panel on Climate Change) special report on global warming has shown that if the temperature continues to rise at its current rate, global warming is expected to reach 1.5 ° C between 2030 and 2052. This means, for agriculture, more and more challenges to be met, everywhere in the world.

With its experience in manufacturing 100% green and sustainable solutions for agricultural professionals, Arrigoni offers a wide range of solutions even for the most critical areas for cultivation. In the tropical and subtropical belt, therefore, it now becomes possible to produce valuable crops, such as berries, pomegranates, etc.

One of the smartest solutions is undoubtedly the Net House, a system that offers a more sustainable and efficient approach to cultivation and to which several agrotextile screens offered by Arrigoni fit perfectly. Depending on the needs of the culture and the fabric that composes it, under Net House, in fact, the need for plant protection products can be reduced and at the same time it attenuates the negative effect of bad weather, such as hail, strong wind and excessive sunshine. In other words, it is versatile and is a compromise solution between open field and greenhouse production, which can offer many advantages over both, such as lower installation costs on the one hand and more comfortable climatic conditions for the development of plants on the other hand.

For the installation of Net House, moreover, it is possible to use different innovative agrotextiles among those offered by Arrigoni, depending on the needs of the crop and the climatic zone in which it operates. Among the ideal solutions for the tropical and subtropical belt, there is ROBUXTA®, a heat-reflective screen characterized by high abrasion resistance, thanks to the additional monofilament that protects the weft tape and prevents the latter from touching the cables of the structure, avoiding damage. Thanks to the LD-Light Diffusion additive in the tape, this fabric increases water savings up to 30% and, at the same time, offers a high temperature reduction and ensures the diffusion of light, useful for photosynthesis Plant.

Tests in the field of the effectiveness of a mosquito net made entirely of ROBUXTA® have already been carried out recently in South Africa, on a blueberry production site. The outside temperature of 34 ° C corresponded to a leaf temperature of 28 ° C under the lid. Plant growth was also found to be regular and uniform for all areas of the plot, unlike what normally happens in tunnels, where the side rows suffer from high temperatures. The only factor to consider is that in these net houses the plant cycle is longer, so an early transplant 2-3 weeks before standard planting is recommended, to get the necessary growth at the best market price.

Milena Poledica, Agronomist at Arrigoni, notes: “The challenge that global climate change poses to producers is increasingly complex and must be met with the best technologies. At Arrigoni, we have manufactured and tested solutions in the field which demonstrate high efficiency even in some of the most demanding areas of the planet from an agricultural point of view, such as the tropics and subtropics. In this way, it becomes possible, overall, to introduce crops with high commercial value, which would normally be very difficult to obtain ”.
