FENORGANIC UNIVERSAL is a liquid biostimulant: a single-cell freshwater algae solution (25.00% w/w) with 1.00% w/w potassium oxide (K2O) and a density of 1.01 kg/L. It is applied by the foliar route, 2-3 L per 1,000 L of water per application, and by fertigation, 3-6 L/ha per application, on fruit trees, vegetable and arable crops; in severe deficiency, up to 4 applications.
At transplanting it is used as a 10% solution, directly on the seedlings or by tray immersion. In our olive grove fertilisation programme it goes into all four annual foliar treatments, at 3 L per 1,000 L tank. The indicated timings are the vegetative stage, post-flowering and the fruit set and ripening stages. It is listed in the Ecocert input attestation as suitable for use in organic farming and it is supplied in five pack sizes, from 250 mL to 1,000 L.
