LABTAR distinguishes itself by technological supremacy as it manufactures a product they know from the basis. Processing of selected limestone results in fine flour that is then granulated. That is why granulated agricultural limestone LABCALC has gained thousands of satisfied customers.

According to classification of fertilisers and fertilising, this product is included in the variety 04. This variety features high content of CaO min. 50% and extremely fine grinding. It results in improvement of chemical, physical and biological properties of soil, thanks to which we can observe drastic increase in crops and decrease in fertilising costs.

LABCALC granulated agricultural limestone

Highly-reactive granulated agricultural limestone with excellent solubility that guarantees effective increase of soil pH and supply of calcium to plants. It is produced from limestone dust with size reduction below 90 micrometres. The highest size reduction accelerates product reactivity and enables to decrease soil acidity already in the first season of its application. This fertiliser improves chemical, physical and biological properties of soil for a long period, thanks to which crops increase substantially and fertilising costs decrease.

application

It is assigned for all types of soil in arviculture, horticulture, orchardry, forestry, on grassland. The product must be sowed with standard fertiliser distributors, for top dressing, post-sowing or pre-sowing for aggregate. Calcium fertilisers have best performance in moist environments. Therefore, we recommend sowing on the top of levelled field where granulate will be able to decompose and permeate inside humus with rain water. It is safe and can be used in the stage of plan growth as it won’t “burn” nor “dry” the plants. The rate of action is also conditioned by fertiliser grain size reduction and the degree of mixing with soil. It must be remembered, though, that the most precious layer is the arable layer.

sowing time/doses

Product can be sown in spring (pre-sowing and for top dressing) and in autumn until winter (post-harvest and pre-sowing). Doses depend on soil pH and its quality. Knowing those parameters, you may execute liming effectively, maintaining soil pH throughout a respective cultivation. Doses vary from 300 to 600 kg per ha.

asparagus	6,4 - 7,5	high	0,4 - 0,5	from harvest to late autumn
spinach	6 - 7,5	high	0,4 - 0,5	from harvest to late autumn
early potato	4 - 6,5	medium	0,4 - 0,5	from harvest to late autumn

effectiveness of liming

Plants cultivated on acid soils give smaller crops and their quality is worse, e.g.

potatoes cultivated on very acid soil have lower ability to sprout,
clover flowers produce little nectar for bees and the content of mineral nutrients in the fodder is smaller
crops from acid meadows do not contain much protein.

technology of liming

liming is not combined with slurry or liquid manure spreading and scattering dung, as it leads to huge loss of nitrogen in those natural types of manure. Granulated lime application must be made at least four weeks later.
liming is not combined with dispersal of phosphatic fertilisers. It this case it is aimed at preventing phosphate retardation, namely transformation into forms not available for plants. Granulated lime application must be made at least two weeks later.

Calcium fertilisers TARWAP

They are manufactured from natural limestone with high content of CaCO3. Calcium carbonate min. 93%, size reduction below 90 microns and high reactivity of products guarantee effective regulation of soil pH, improved structure and fertility of soil. Regular liming with those fertilisers provides plants with calcium, guarantees high crops and decreases costs of NPK fertilising.

application

The product is used in all types of cultivation i.e. in agriculture, orchardry, horticulture, forestry, on grassland and fish ponds. The product is intended for band spreaders, types: Kos, Piast, Motyl and also for disc spreaders. The best time to use calcium fertilisers is after harvest, as soon as possible, (but they may be applied throughout the whole year, depending on the weather conditions and the type of cultivation). The product must be thoroughly mixed with soil (topsoil) with farm implements.

sowing time / dosage size

The product can be sowed in the spring (pre-sowing) and in the autumn until winter (post-harvest and pre-sowing). Doses depend on soil pH and its quality. Optimal dosage of lime is determined by chemical and agricultural stations and it is based on the results of soil reaction tests, depending on soil agronomic category and the type of cultivated plants. Thanks to determination of those parameters, you may execute liming effectively, reaching optimal soil pH required by the respective cultivation. Doses for maintaining soil pH and slight deacidification vary from 500 to 1000 kg per ha.

Liming techniques

Liming cannot be combined with spreading of liquid manure, slurry, and with dung scattering. Sowing must be done after minimum 4 weeks’ break.
Liming cannot be combined with phosphate fertilisers propagation. Their application must take place at least 2 weeks later.

storage

When storing, agricultural limestone must be protected from moisture and pollution. In case of manure composting, it is necessary to select a hardened and impermeable place and to cover the piles with waterproof material in order to protect them from moisture.

precautions during storage and application of fertiliser

Agricultural limestone is non-toxic and it does not require special precautions. It is not a hazardous substance and is excluded from REACH ordinance. When spreading agricultural limestone, suitable precautions must be taken due to the possibility of dusting. Validity period is 24 months from the date of production, providing it is stored in a place protected from moisture and pollution.
