Dolomite

Is a double salt of MgCO3*CaCO3, usually contains admixtures of iron, zinc, nickel and cobalt. Dolomite strongly reacts with 10% HCl after pulverizing or heating the acid.

PRODUCT DESCRIPTION Carbonate and magnesium fertilizers of natural origin from the processing of raw dolomite rocks Carbonate and magnesium fertilizers of natural origin from the processing of raw dolomite rocks.
PURPOSE Maintenance of magnesium richness and soil pH. Correction of magnesium content, maintenance or adjustment of pH.
SPREADING All types of fertilizer spreaders with disc feeder. Standard NPK spreaders
TERMS OF APPLICATION From early spring to late autumn, optimally before sowing, but also for pre-sowing crops. The best effects can be seen, if the fertilizer is spread to stubble and shallow plowed area. Directly before and after liming, mineral fertilizers (nitrogen losses, phosphorus retardation) of manure and liquid manure should not be used. A 15-30-day break is recommended between these treatments. Pre-sowing or top dressing 300-600 kg/ha, intervention 1t/ha to save the crop. 400-500kg/ha can be used for grassland.
DOSE Depends on the pH and soil type, cultivated plant and the degree of grinding 2.5-5t/ha. In agricultural practice, every third liming is used in the sequence: carbonate – carbonate – dolomite – carbonate – carbonate – dolomite.

Calcium carbonate

Naturally, limestone is a rock of sedimentary origin, in which the CaCO3 content is over 90% by weight. Usually not found in pure form. In addition to calcium carbonate (CaCO3), calcium magnesium carbonate (dolomite – CaMg (CO3)2) also contains magnesium carbonate (MgCO3) and admixtures of sand and clay minerals (e.g. silica, aluminium oxides and iron oxides). In nature, calcium carbonate can be in the form of stone, chalk, spar or as marble. Marble has pure calcium carbonate with well-formed crystals. In Poland, there are no proper marbles, only hard varieties of dark carbonates that shine having been polished. Spar is a mineral containing CaCO3 in the form of calcite. Chalk comes from younger geological eras.

Calcium oxide

It is formed by firing calcium carbonate (CaCO3 › CaO + CO2). The source of calcium carbonate involves limestone deposits – stone occurring in nature. Calcium oxide has hygroscopic properties. It binds rapidly with water to form calcium hydroxide, with heat being released. In practice, the calcium carbonate decomposition process is carried out at a temperature of 900-1000°C and usually lasts 5-9 hours. Stone is fired in limestone furnaces, i.e. lime kilns; two groups are distinguished:

– working periodically (in the field),

– working continuously (circle, shaft, rotary and tunnel).

 

Shaft furnaces are of the greatest importance for the lime industry. Their design ensures continuous operation, mechanized material loading and lime removal allows for the most effective use of heat, and at the same time saving costs. Production is carried out by firing solid fuel – short-flame (e.g. coke, anthracite).

 

Depending on the rate of extinguishing, we distinguish lime:

– fast extinguishing (extinguishing time up to 10 minutes)

– moderate extinguishing (extinguishing time 10-30 minutes)

– slow extinguishing (extinguishing time over 30 minutes)

 

Fired lime with a high content of CaO can be extinguished quickly; lime with magnesium oxide content requires a longer time and a higher extinguishing temperature.

Magnesium sulphate

Loose, bitter salt MgSO4x7H2O dissolves very well in water and immediately nourishes the plant with magnesium and sulphur. It shows compatibility with most fertilizers and pesticides (remember to follow the manufacturer’s recommendations). Especially recommended in the case of visible Mg and S deficiency, but it should be remembered that it does not replace soil fertilization with these components. Granulated magnesium sulphate is suitable for fast-growing plants, which, in a short time, create a lot of biomass, and are particularly sensitive to the lack of these nutrients.

Calcium sulphate

(CaSO4x2H2O) Suitable for fertilizing all crops, including soils with low pH and low sulphur content. Particularly recommended for sulphur-loving plants, e.g. rapeseed. Cereals and corn also provide good yields when using CaSO4. Gypsum consists of sulphur in the sulphate form, which is directly taken up by the roots, supports the production of chlorophyll and avoiding nitrogen losses in the soil environment. If you do not have enough time for liming, calcium sulphate is an ideal solution to reduce the effects of toxic aluminium; sulphate easily combines with Al3+ ions to form non-toxic forms of aluminium – AlSO4+.

 

A fantastic solution for springing grasslands before starting vegetation!
