Boosting soil life with Perlka®
The well-established fertilizer supports food security and sustainable food production.
What is a fertile soil and what does it need?
There are different kinds of soils with varying characteristics such as clay, gravel, volcanic ash or sandy soils. A good soil is one which has high water retention capacity - according to its soil type - to help crops survive dry periods. Water, sufficient nutrients and a balanced biological activity in such a soil are essential to add life to the soil and to produce vegetables, fruits and other crops sustainably.
What is Perlka®?
Perlka® is a dynamic and flexible fertilizer. It not only supplies the soil with essential nutrients such as nitrogen and lime but also offers a wide range of other unique effects. Many farmers prefer Calcium Cyanamide Perlka® in order to prevent yield and quality losses during increasingly tight crop rotations, or to be able to manage them properly once again. Why? - because soil health is more important than ever to ensure a sustainable production.
How does Perlka® help to create a healthier soil?
By applying Perlka® to the soil the activity of soil enzymes including dehydrogenase, catalase, protease etc. is fostered due to its lime and nitrogen content[1]. Lime prevents acidification and nitrogen helps additionally to support the living conditions of soil bacteria and microorganisms[2]. Moreover, a Perlka®-fertilized environment supports the living conditions of saprophytic fungi, e.g. fungi that are responsible to degrade straw and other infectious plant residues on the soil surface[3]. Many parasitic fungi cannot benefit from this nitrogen source.
