Ecogran^® – Koszelowka Soil Lime

A granulated, non-powdery calcium fertilizer.

Shows very good chemical and physical properties. Has remarkable purity. The form – 2,0-6,0 mm and 5,0-9,0 mmm granulate, allows for easy sowing and fast mingling with the layer of soil. 100% ECOLOGICAL ( IUNG certifikate), produced on the ground of own natural bed of writing chalk.

The Koszelowka Soil Lime is produced in 40 kg bags, as well as 1 ton big-bag type packages..

Chemical composition of the Koszelowka Soil Lime in mg/kg:

Application of the Koszelowka Soil Lime has the following beneficial effects:

increased effectiveness of the application of mineral fertilizers,

neutralization of the acidic effect of physiologically acidic fertilizers,

neutralization of toxic effect of aluminum and manganese ions appearing in acidic soil,

increased physical properties of soil,

improved biological properties of soil through faster decomposition of post-harvest residues, organic fertilizers, increased activeness of nitrogen-binding bacteria,

possibility of cultivation of plants more useful in agriculture but not very demanding as regards the reaction of soil, e.g. alfalfa.

Circumstances justifying the necessity of recultivation liming of soils in Poland.

1. More than 50 % of the general acreage of soil in Poland show very acidic or acidic reaction (pH<5,5), and this situation has not changed over the past 20 years. In spatial formulation, in as few as two provinces (such as Kujawy and Pomorze, as well as Opole) the share of such soils amounts to less than 40%, whereas in four provinces (i.e. Lodz, Mazowsze, Podkarpacie, and Podlasie), soils with pH below 5.5 occupy as much as 60-80 % of the entire arable area. In terms of the state of acidity of soils, Poland appears very unfavourably in comparison with the neighbouring countries.

2. Strong acidification of soils in Poland results primarily from the type and origin of mother rocks, and the course of the soil creation processes, but not without importance are also causes of anthropogenic character. Such anthropogenic causes include acidic rainfalls (sulphur and nitrogen oxides, and ammonia), as well as acidifying effects of mineral fertilizers, mainly nitrogen based. The total load of these acidifying substances brought together to a common dominator of hydrogen ions is currently estimated for approximately 5 kmol H+ *ha-1, and in the 80’s, it came up to the value of 9 kmol H+*ha-1. To make these figures more approachable, it should be highlighted that to neutralize 1 kmol H+, 28kg of CaO is needed.

Summarizing, it is assumed that annual rainfall of 5-6 kmol H+*ha-1 of soils with pH below 4.8 (soils showing interchanging acidity) may lead to degradation of such soils in a short period of time. Soils with pH below 4.8, constituting a significant portion of acidic and very acidic soils, are therefore potentially threatened with degradation processes.

3. The acidic reaction of soils is connected with the number of their unfavourable physical and chemical properties. One should mention harmful forms of aluminum and manganese in soils with pH below 5.0, decreased absorbency of plant nutrients (mainly phosphorus, potassium and molybdenum), as well as increased accessibility of heavy metals for plants (mainly cadmium and lead). The latest specification of results of the survey carried out by the Regional Chemical and Agricultural Station (OSChR) show that in the group of very acidic soils (pH below 4.5) more than 50 % is at the same time characterized by low and very low content of absorbable phosphorus, and over 65 % - by low and very low content of absorbable potassium. In the group of soils with neutral reaction such a content of phosphorus is only present in 14 % of soils, and potassium in about 25 % of soils.

4. The only method of adjusting the reaction of soils is their liming. The calculations taking into consideration the need for liming of soils, and the recommended doses of CaO show that to adjust the reaction of Polish arable land, it would be necessary to use approximately 20 mln tons of CaO. Even subtracting very light soils and very acidic soils, occupying an estimated area of about 1.5 mln ha, which should be excluded from agricultural use, the minimum requirement for lime for arable land amounts to some 16 mln tons. To this the need for liming of arable green land, forests, in particular young forest plantations, ponds, and selected open water reservoirs (lakes) should be added, as well as the increasing need for lime used for hygienization and utilization of sewage waste, as well as production of various types of organic fertilizers. The need for lime is worth comparing with the consumption of lime fertilizers, which over the past decade has not exceeded 100 kg CaO per 1 ha (approx. 1.5 mln tons CaO per annum).

Application:

The Koszelowka Soil Lime is ideal for fertilizing field plantations, orchards, greenhouse plantations, arable green lands, flowers and lawns.
