When to use

Pre-sowing and top dressing treatment for all crop species; particularly recommended for soils with low and very low affluence of assimilable forms of potassium and for crops with high nutritional requirements for this element.

* In order to accurately identify fertilisation needs, it is necessary to carry out chemical determinations of the nutrient content of the soil.
** Potato on manure: 400-500 kg, potato without manure: 600-800 kg.
