Agro AMMONIUM SULPHATE is a high-quality nitrogen fertiliser. It contains long-acting nitrogen for healthy and rapid growth. This fertiliser has a significant sulphur content and is therefore very advantageous when growing plants that require high sulphur levels (potatoes, onion vegetables, brassicas, horseradish...). It promotes the formation of essential oils in onions, giving them a more piquant taste. The fertiliser has an acidic reaction, therefore it is not suitable for acidic soils.
