OrCal® organic-mineral pH-regulator with active calcium hydrate*. It deacidifies, fertilizes the soil and nourishes the plants.

Calcium in OrCal® pHregulator is in the form of active calcium hydrate Ca(OH)2, which is a compound with very high reactivity and deacidification properties. The process of soil deacidification with the active calcium hydrate is more environmentally friendly than the deacidification with calcium oxide CaO. OrCal® pHregulator, in addition to soil deacidification properties, thanks to the organic substance content improves its structure, increases the content of humus and biological activity. It also provides nutrients to the crop plant. The product is recommended as an anti-acid remedy and for the reclamation of degraded soils following intensive agricultural use.
