Description
18-22-5 roller granule compound fertiliser is produced by roller granulation, compacting the nutrients into a dense, evenly sized granule. The result is a hard particle with little dust that flows well through a spreader and throws a consistent pattern at width. Like any compound granule, each one carries the declared analysis, so what leaves the spreader is what is on the label. Phosphorus leads this analysis at 22%, against 18% nitrogen and 5% potassium. Phosphorus is the establishment nutrient – root development, early vigour, flower and seed set – and it moves very little in soil, so it has to be placed where young roots will find it. A phosphorus-dominant analysis is a sowing and planting product rather than a mid-season one. 45 units of nutrient in total. Supplied in bulk, bulka bags or bagged, minimum order 10 MT, delivered Australia-wide and shipped worldwide. A Certificate of Analysis and Safety Data Sheet are issued against the batch you receive.

Where 18-22-5 Roller granule compound fertilizer Is Used
Establishment and early vigour
Phosphate leads this analysis, which puts it in the seeding and establishment window. Because phosphorus is immobile in soil, banding it near the seed generally outperforms broadcasting the same rate.
