About us

MORTAR AKMENĖ UAB produces soil stimulus measure Kalktrąšė V and Kalktrąšė HUM.

The following plants like acid soil: field spurry, scleranthus anus, field horsetail, small sorrel, wild radish. If you find them in your garden, see these plants in the fields, know, that soil needs liming. In Lithuania acid soils prevail in the western, south-eastern part. Soil acidity is described by its pH value (1 to 14): 1-6 indicates acidic, 8-14 means alkaline, and 7 is considered neutral soil.

In order to prevent soil from acidification, leading to weed infestation, impairing fertility, devastating the soil, the soils have long been limed. Liming is also associated with more efficient functioning of land reclamation systems, as less weeds whose roots are able to clog the drains, grow in the limed soils.

Liming changes weed species composition, in such crops number of weeds indicating that the soil is acid reduces. The studies carried out by Vėžaičiai branch of Lithuanian Institute of Agriculture showed that with the decrease in soil acidity from pH 4.1 to 6.6, in all rotation crops (oilseed rape, barley, clover, winter wheat) crop weed infestation fell by a quarter, and in some cases even by half. In some cases, this weed reduction was observed for soil with pH 5.4 to 5.9.

It is the best to lime fallow soil, acidity sensitive plant fore crops. You can also pour lime fertilizers on the stubble.

Lime substances will not be effective if they are poorly inserted. The main requirement is to make its mix with arable soil as uniform as possible. It is absolutely inadequate to plough it deeply with plough. Spread lime substances may be inserted with the help of disc harrow, cultivator, but most effective is to stir it with a mill. Later, when ploughing it is fully mixed throughout the plough layer.

The processes going on in the meadow and pasture soils are different from those which occur in arable land. Liming recommendations are different for meadows and pastures. The soil pH is best adjusted according to the most sensitive plants. Lime fertilizer works there in much more different ways than in the arable land; there it not only improves the soil, increase grass yield, but also has a positive effect on species composition of grasslands. It is stated that when soil pH is increased by 1, white clover among the grasses and legumes grows up by 13 percent. However in the heavily fertilized grasslands more calcium is absorbed by perennial grasses, which means that its content in the soil decreases and must be restored.

Most of the liming materials offered currently in the Lithuanian market have meal structure. Therefore its even insertion into the soil is extremely problematic. Mortar Akmenė, UAB offers granular liming material Kalktrąšė V and Kalktrąšė HUM. It is the product that contains antacid liming properties and soil feeding compounds MgO (magnesium oxide) SO3 (sulphur oxide), K2O (potassium oxide), Fe2O3 ( iron oxide).
