While at nitrogen is actual economical and ecological criterion in the case of potassium rather dominates economical one. In the case of inorganic nitrogen is possible to update directly its content in topsoil layer by that one in subsoil with occasional respecting the skeleton content. In the case of potassium is rather acceptable indirect way of topsoil-K updating because potassium bioavailability is more influenced by soil moisture, root system distribution (density) and also by soil buffer capacity with respect to this element that are not available for practical application
