Bal-co GreenLine FAQ's


Zeolites are hydrated alumino-silicate minerals of alkaline and / or alkaline earth elements (Na +, K +, Ca ++), belonging to the roof-silicate family. They are found mainly in diagenised pyroclastic rocks (tuffs, ignimbrites) and are characterized by their particular microcrystalline structure, which gives them important properties of water retention and cation exchange capacity.

In nature there are 52 different species, the most widespread in the agricultural sector are chabasite and clinoptilolite.

When we talk about ‘zeolite’ we refer to the mineral, with the term ‘zeolitite’ we mean instead a rock with a zeolitic mineral content higher than 50%.

The term zeolitite was coined by Elio Passaglia, professor of Mineralogy at the University of Modena and the world’s leading expert on zeolites, precisely to classify rocks with a high content of zeolitic minerals.

From the mineralogical point of view, chabasite and clinoptilolite differ mainly in their formation, which therefore directly influences their properties.

Chabasite originates from typically fluid magmas, rich in alumina, while clinoptilolite is derived from more viscous magmas, therefore poorer in alumina; this causes the chabasite to have a greater number of aluminum atoms in its structural scaffold than the clinoptilolite, and consequently a greater decompensation of electric charge. Because of this fact, the chabasite has higher water retention and cation exchange capacity values ​​not only to clinoptilolite, but to all other natural zeolites (Source: “Contribution of the zeolitites in problem mitigation”, Prisa & Passaglia, 2016).

Another difference is in the cationic content and in the crystalline structure: the chabasite crystal is pseudo-cubic and rich in calcium and potassium, while the clinoptilolite crystal is lamellar in shape and richer in sodium.

Absolutely yes! The chabazite zeolitite is allowed in organic farming according to the Legislative Decree 75/2010 of the Ministry of Agricultural, Environmental and Forestry Policies.

But pay attention! In organic farming, only certified products such as ‘zeolitites’ (so rocks with zeolite content> 50%) based on the RIETVELD method, a particular method of X-ray crystallographic analysis able to distinguish the zeolitic mineral from tuff, are allowed glassy; this methodology is, up to today, the only officially recognized by the Ministry to identify a zeolitite.

Chabasite can easily be associated with typical conventional defense products. It does not create interference with copper and / or sulfur or other phytosanitary products, on the contrary its protective barrier effect against fungi and insects is perfectly complementary and prolongs the action of the associated products, thus allowing for fewer treatments.

The ZEM70 product has an extremely fine granulometry, with a D90 of 15 µm (it therefore means that 90% of the particles have a size of less than 15 µm). This granulometry has been designed specifically to guarantee a product able to remain in liquid suspension for as long as possible, without any problem of pipe fouling or clogging of the atomizer nozzles.

Both the granular product and the micronized bring their functions on almost all the most widespread crops in the agricultural world. The granular product ZEP70, as a soil corrector and soil conditioner, is widely used in horticulture, nursery gardening and field cultivation; the ZEM70 micronized product is widely used on all the main types of fruit crops (grapes, apples, pears, apricots, cherries, peaches, hazelnuts, etc.).
