The present invention is related to a formulation based on (i) micronized natural
calcite mineral (MC) of particles size from 500 nm to 5 μm, which contains variable amounts of
calcite (CaCO3),
dolomite [CaMg (CO3)2], ankerite [Ca (Mg, Fe, Mn, Zn) (CO3)2], and
quartz (SiO2); (ii) micronized
zeolite of particles size from 500 nm to 5 μm, of general formula (Mn+) x / n [(AlO2) x (SiO2) y].mH2O (MZ) wherein Me=Na, K, Ca, Mg, Fe, Zn, Mn, Cu; whereas ratio of
silicon to aluminum, y:x is between 1:1 to >10:1; whilst m is number of crystalline water molecules which can be from 0 to >20; and of (iii) one or more additives which, with components (i) and (ii), yiled in the final form of the formulation suitable for practical use:
powder;
wettable powder; concentrate for suspension; or granules; and / or which enhance basic biological actions of (i). The applications of the formulation result in the following effects: more effective stimulation of photosynthetic process in plants; more efficient stimulation of
plant growth; enhanced viability of plants to stresses and diseases; improved absorption of nutrients from
calcite mineral itself; improved absorption of nutrients applied through the soil; and especially, increased
crop yields.
