Many of the fertilizers and pesticides commonly used bring copper to the soil with risks of accumulation and phytotoxicity.
The soils can receive heavy metal inputs, both from atmospheric depositions, but also with the contribution of fertilizers and plant protection products. In the long run, the accumulation of these elements, generally well retained by soil, can negatively affect the fertility of the soils or worsen the quality of agricultural products, or contaminate surface and groundwater.
Many metals such as copper and zinc end up being harmful at the level of high soil concentration for microbial biomass and for higher organisms such as earthworms and plants. Other metals are not essential (Cd, Hg, Pb) and for this reason they are potentially toxic even at low concentrations. The sensitivity of different cultures to the toxic effect of copper varies widely. It is difficult to evaluate the phytotoxicity of this element, as it accumulates in the roots, damaging in the first place this organ not directly visible.
Mineral and organomineral fertilizers may contain copper resulting from the raw materials used for their production. In sewage sludge, on the other hand, copper is concentrated which is removed from the water subjected to the purification treatment, and which can therefore derive from the most varied domestic and industrial sources.
Among the agricultural sources of contribution to copper soils we must include plant protection products based on this metal. Important inorganic anticryptogamic agents, especially used for the control of downy mildew, are copper-based compounds. In fact, several studies have shown important copper accumulations in vine-grown soils, both for the superficial layer and for greater depths, and have credited the lack of environmental sustainability of cupric treatments in viticulture, in particular in the biological defense regime.
With respect to the copper quotas applied to the soil, it is important to consider the high general capacity of the soils to retain (and therefore accumulate) heavy metals, without forgetting that a total amount of metal in the soil can transfer to the percolating or superficially flowing waters.
From these considerations derives the need to deepen the studies on the real toxicity of copper in soils, in particular for those that potentially have characteristics favorable to the risk of phytotoxicity (low amount of organic substance).
Scientific research has dealt little with the issue, but the results obtained seem to agree that this metal has negative effects on most of soil species, leading to a decrease in the biodiversity of the agricultural environment, an effect that increases over time due to the accumulation of copper. The presence of bacteria and fungi in the soil, but also on the aerial parts of the plant, can represent a particularly effective defense mechanism against microscopic plant parasites and enrich the soil with mineral elements, fundamental for the crops; Copper-sensitive animals, such as earthworms and snails, can improve the texture of the soil, creating channels for aerating the roots and promoting the decomposition of organic matter, improving soil quality. Copper also has a documented insecticidal action and its accumulation in the environment could lead to the removal of coccinellids and pollinators.
This is why when we talk about organic farming we have to be careful, because doing 40-45 copper treatments on a plant has little biological!!.

For some years the chestnut section of the Campania region is going through a period of deep crisis. Already decimated by the dreaded gallipid gyro insect (Dryocosmus kuriphilus) which has contributed to a large reduction in the productivity of the sector, recently the chestnut woods of Campania have suffered a strong attack of parasitic mushrooms and ciders, bringing down regional productivity to 20-30% compared at maximum potential – according to estimates by Cia Campania.
As reported by ItaliaFruit News, the Campania Region has decided to open a discussion table on this issue that has become of fundamental importance; the main turning point will concern the reclassification from a juridical point of view of the chestnut woods, which will turn from being treated as wooded areas to be considered orchards in all respects. This change will allow the revision of regional regulations for the creation of protocols containing the basic guidelines for the biological and integrated defense of chestnut woods.
In the light of these new protocols that will soon take off, we at Balco GreenLine recommend a treatment based on ZEM70 zeolitite, very useful especially against the development of fungal diseases thanks to the high water retention of the zeolitic mineral; considering the very smooth surface of the chestnut and the size of the plant, we suggest to treat using 12 kg per hectare of ZEM70 zeolitite in liquid solution.
In the picture above you can see the healthy and ripe olives from the experimental olive grove of Balco GreenLine in Pian di Mezzo, Island of Elba, ready to be taken to the mill, for a cold pressing, a few hours from the harvest.
The conversion for three years in which the olive grove was treated only with Balco GreenLine zeolitite ZEM70 and kaolin GREENC(treatment dose: 5 kg kaolin + 1 kg zeolite per 100 liters / ha) will make us achieve this yearBIOLOGICAL certification.
The four seasonal treatments have given excellent results for the defense against the olive fly, but also to give relief to the drought that hit the island this year.
So we invite you to try this new biological treatment in your olive groves, the results are guaranteed!
The DID (Double Immediate Disinfection) is a technique of pruning and sterilization-scarring that Dr. Prisa created and that he has been experimenting in some agriculture companies he works with.
Obviously it is born for Micronaturale® agriculture (therefore not using synthetic products), but it can also be applied in organic and conventional agriculture, associating the common defense products.
It consists of the following steps:
– a first pre-disinfection and protection of plant tissues by spraying the branches and leaves with protective films (microlitized chabasite zeolitite, mechanical-protective barrier action) and microorganisms (antagonists and colonizers of the surfaces); to improve performance we recommend adding plant extracts derived from citrus fruits + equisetum, with antifungal action.
– after 2 days from the first disinfection treatment, proceed with the pruning of the tree or the shrub;
– as soon as possible (do not allow too much time for pathogens to penetrate into the plant from the wounds created) perform a second treatment with protective films of activated chabasite zeolitite and microorganisms (antagonists and colonizers of the surfaces); to improve performance we recommend adding plant extracts (extract of aloe + manuka with antifungal, antibacterial, antiviral and cicatrising action). The purpose of the second treatment is obviously to disinfect the cutting areas, occupy the sites of infection, facilitate the healing of wounds.
This intervention mode guarantees:
– better disinfection-healing of wounds;
– a significant reduction in the possible development and contagion of fungi, viruses or bacteria that penetrate the cutting areas;
– an optimization in terms of time and an improvement in the protection of the cutting areas, which remain less exposed to external biotic and abiotic agents, thanks to the second treatment of immediate disinfection-scarring.
DOSAGE OF CHABASITE ZEOLITITE: (only the quantities of chabasite are indicated, to which it is possible to associate the common plant protection products)
1st treatment (pre-disinfection) 3 Kg / ha of zem70 in liquid form;
Within 2 days from treatment proceed with pruning;
2nd treatment (disinfection-scarring) 5 kg / ha of zem70 in liquid form;
In biological, associate with chabasite zeolitite, 400g / ha of copper and 2.5 kg / ha of sulfur
It is with great satisfaction that we announce a new collaboration of distribution with NOVA, a Sicilian company specialized in the production and distribution of innovative fertilizers, born with the entrepreneurial ambition to make a contribution to the improvement of agricultural production, respecting and protecting the environment.
This collaboration agreement was born mainly from the fifty years experience of Bal-Co in the field of production and processing of mineral products for the industry with the specific aim of creating new products dedicated to the protection of both man and environment, ideal for the use in organic farming.
“The partnership between NOVA and Bal-Co GreenLine has started – says Dr. Alberto Carestia, marketing director of the Sicilian company – has as its primary objective to provide farmers with increasingly specific and effective solutions, which allow to maximize yields and the quality of production, limiting the use of synthetic crop protection products “.
We have already spoken in one of our recent article on the possible impact on human health of plant protection products commonly used as pesticides in nature, and in recent days a very important news concerning this delicate topic gained attention: as reported online by the international fresh fruit and vegetables news FreshPlaza, the 19 and 20 July 2018 the commission of the European Union has proposed to the member states a debate concerning the reduction in the use of phytosanitary products based on copper salts.
These products based on copper salts have been used in agriculture since the 19th century, and especially in viticulture their use has always been considered of fundamental importance in the fight against various fungal infections that can affect the vine plant. However, in the face of their danger to humans, already in 1991 the EU envisaged a program to reduce copper salts phytosanitary up to prohibit it completely by 2002, only to postpone the date with concessions in extension, of which the last will have expiry in 2019.
I am aware of the importance of these substances to farmers, especially organic producers, but my priority is to protect health and the environment.
These are the words of Vytenis Andriukaitis, EU Commissioner appointed as competent in the matter. The damage caused by a prolonged exposure to these products is not only for the environment, but also affects the man, with possible skin and eye damage, up to problems related to pregnancy and the fetus with regard to pregnant women. According to sources close to the dossier, already this week Brussels will propose a renewal of the authorization for 5 years with reduction of the use limits from 6 to 4 kg per hectare per year.
With this aim of reducing the use of phytosanitary products based on copper salts, our ZEM70 activated Chabasite Zeolitite product is without a doubt a very good and 100% natural alternative. With a traditional supply of 5-6 kg / hectare of ZEM70 micronized zeolite, it is possible to reduce the use of copper-based products in the formulation by approximately 30-40%. Furthermore, according to studies conducted by Dr. Domenico Prisa, it has been possible to see how the zeolite works in complete synergy with copper, without hindering its action but on the contrary increasing its anti-fungal power and above all extending its effect over time. thus allowing a reduction of the necessary treatments.
According to a recent study carried on in France (we report here the Italian article on Italiafruit news) by the national institute of health, it has been discovered a direct connection beetween the increasing of metabolic illnesses (such as obesity and diabetes) and a diet based on fruits and vegetables treated with chemical pesticides.
Even thou the styìudy has been carried on rodents and there’s no proved scientific evidence on the effects on humans, this news points directly to the unrestrained and compulsive usage of chemical pesticides to treat goods coming from nature, something we daily eat in our houses; Bal-co GreenLine wants to push on the importance of believing in a biological farming, based on 100% natural products, respecting not only nature, but mainly our safeness on what we eat every day.
This standing, Bal-co GreenLine products are certainly the answer to a farming safer for environment and huamn health!
(Up in this picture: Apricots of the Faralia variety, to be collected in farming company of Claudio Pellerino at Magliano Alfieri, Piemonte)
It has been shown recently that Bal-co GreenLine Chabazite Zeolite application has improved the quality of the incoming maturation varieties of apricots, which is really appreciated by customers.
The main goal, creating a physical barrier against pathogens such as Monilinia, has been achieved thanks to Zeolite , which creates an hostile background, blocking insects growing.
Faralia apricots are shown in picture, they will be completely mature in incoming weeks; they have been treated with Zeolite ZEM70 in the farm of Claudio Pellerino, an innobvtive and environment-sensible farmer, who has been paid back for his braveness and determination with a very awesome yeld.
