Triple 16 16-16-16 Fertiliser 20kg

Triple 16 (16-16-16) Fertiliser 20kg from Nutrigrow is a high-quality, professional NPK fertiliser designed to provide balanced nutrition for grasslands, paddocks, and pastures. Its equal mix of nitrogen (16%), phosphate (16%), and potassium (16%) ensures consistent top growth, root development, and overall plant health.

This versatile fertiliser is particularly suitable for grass intended for grazing or hay production, but can also be applied as a general feed to improve soil fertility and correct minor nutrient deficiencies. Its balanced nutrient profile makes it a flexible choice for areas slightly deficient in phosphate or potassium, while still supplying essential nitrogen for leaf and shoot development.

Triple 16 is supplied in a 20kg bag, suitable for small- to medium-sized paddocks, and is also available in a 600kg bulk bag for larger areas. The granules dissolve quickly, providing nutrients within 1 week, and offer longevity of approximately 6 weeks, making it an effective choice for multi-season applications.
