After sieving, we can subject the coco peat to further treatment, e.g. the coco peat can be washed. Elements that are freely soluble in water, such as potassium, sodium, and chloride, are removed. The salt content is reduced to an EC < 1.0 mS/cm [1:1.5 water extraction method]. In addition to this, we can also buffer the coco peat. During this process, calcium [2+] is introduced in order to remove monovalent positive ions such as potassium [1+] from the coconut complex. In this way, we remove not only elements that are soluble in water but also elements that are bound to the coconut complex. Washing and buffering are done in our own coconut fields.
