POLCALC of the 3rd generation is for the soil what an antibiotic for a human. It can be used “at a guess” or consciously to achieve maximum positive effects. In the following note we would like to encourage to conscious and intelligent use of our products in the system of recovery and maintaining proper chemical conditions (pH) of soil.

Recommended by POLCALC system of liming includes three essential steps: diagnosis, therapy and prevention.

1. DIAGOSIS . It is worth reminding again  that as much as 66% of soils in Poland show strong or very strong tendency to acidification. The farther north the stronger tendency to acidification occurs. Therefore, it is very probable that also your fields experience over-acidification what directly affects the quantity and quality of agricultural production.

The first alarm bell, visible to the naked eye, is the occurrence of browning of shoots, browning of young leaves, leaf spots, cabbage clubroot, root blight, typhula, etc. Moreover, you can also pay attention on plants growing on field margins. If you see ferns, horsetails, moss, sorrel – it is almost sure that the soil is acidified!

If you notice one of these unfavourable indicators (decrease in quantity of agricultural production, diseases, above mentioned weeds) it is necessary to ask a specialist, for instance our company or a local chemical-agricultural station.

Experts will carry out standard analyses: determine the soil pH as  a result of laboratory works, and the degree of soil compactness (agronomic category of soil). It is worth noting the latter of the mentioned elements. Ph determination itself is not enough!  The soil ability to neutralise the acidification is highly dependent on its physical properties (structure, hydration). It is easy to make a mistake (especially applying calcium oxide) in determination the dose of lime not taking into account the soil structure.

After determining both above mentioned properties, a class of needs for soil liming of a specific field is established. In our climatic conditions the result will usually indicate class IV (liming needed) or V (liming necessary). Now, we go to the next stage.

2. THERAPY. Experts suggest various ways – strategies of soil liming. They depend on earlier determined classes of liming needs:

classes IV-V (liming needed and necessary) – the use of increased doses of granulated POLCALC OF THE 3RD GENERATION lime is advisable.

 The main objective is to restore the soil its natural chemical properties by elimination of the acidification.

Attention! The exact dosage of the fertiliser can be determined by an expert from our company!


Most often after the application of increased doses of calcium fertiliser the pH stabilizes on the level of the 3rd class of needs for liming (liming advisable).

Although, it does not mean resignation from the need for constant, annual monitoring the needs for liming. You need to be aware of a fact that as a result of falls (washing) soils in our climatic conditions lose 200 – 400 kg of lime per 1 hectare! If lime absorbed by plants is added, it is easy to realize a fact of the necessity of systematic care to maintain proper chemical conditions of soil. Therefore, what should be remembered is:

– necessity of stabilizing liming (with reduced doses) of soil,

– monitoring of the soil pH and undertaking flexible actions to increase doses of applied lime – in case of increasing acidification!


At the end, let us say once more:


Firstly, AWARENESS OF NEEDS, secondly, INTELLIGENT AND EXACT APPLICATION, thirdly, CARE AND FLEXIBILITY – these are the factors that optimize the use the POLCALC OF THE 3RD GENERATION  fertilisers and increase your satisfaction of the application!
