Calcium, an essential element in the nutrition of cultivated plants, is found in the soil in non-replaceable forms within various minerals such as calcium carbonate, calcite, dolomite, calcium phosphates, apatites, and silicates. These forms of calcium are inaccessible to plants until they decompose and dissolve, at which point they can be absorbed. Due to the intensive use of soil and the insufficient addition of calcium through fertilizers, calcium is often completely depleted from the arable layer. This leads to increased soil acidity (a decrease in pH value), which in turn causes the breakdown of the soil's complex structure, leaching of other nutrients, deterioration of soil structure, and, naturally, a lack of calcium as a biogenic element for cultivated plants. Calcium is removed from the soil through the yield of cultivated plants, and once it becomes available in a soluble form, it is practically unprotected from leaching. As a result, most of our soils, which were once rich in calcium, are now depleted of it in the arable layer. The only corrective measure, or neutralization of such soils, is the application of **liming**.

DUCAZEL ensures stable and consistent nutrient supply to plants over an extended period. Zeolite prevents the leaching of nutrients from the root zone and their runoff into deeper soil layers through underground and surface water. Physical and mechanical properties of zeolite: • increases water absorption and retention capacity in the soil • increases the soil's ability to retain nutrients • regulates soil acidity, pH value • improves plant nutrition, develops root systems, intensifies growth and fertility • reduces plant diseases • contains essential elements for development: magnesium, potassium, and calcium • acts as a soil conditioner • is an effective agent in soil remediation The positive effects of efficient and widespread ZEOLITE application in agriculture relate to its ability to effectively adsorb moisture and nutrients, thereby improving yield and crop quality. It regulates soil moisture both during drought periods and in cases of excess water. By adding zeolite to the soil, we gain an excellent moisture trap and guard, as well as a reservoir of macro- and micronutrients essential for plant development. Zeolite has a positive effect on plant roots at low temperatures, with a freezing point of -20 ℃.

Ducazel - ground zeolite

Due to the outstanding natural quality, origin and production process of zeolites, Ducazel has an expanded range of adsorption characteristics. This makes it an effective adsorbent of mycotoxins of various physicochemical properties (from weakly polar to strongly polar, from hydrophilic to hydrophobic). At the same time it is very selective so that it does not adsorb nutrients (vitamins, oligoelements and amino acids).
