Description
15-15-15 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. The analysis declares 15% nitrogen, 15% phosphorus (as P2O5) and 15% potassium (as K2O) – an even ratio, carrying 45 units of nutrient in every hundred kilograms. An even analysis is the right choice when no single nutrient is limiting and you want to hold the crop steady rather than drive it in one direction. Where a soil test shows one element short, a balanced product will not correct it, and we would blend to the ratio the test calls for instead. Supplied bulk, in bulka bags or bagged, from 10 MT. Delivered Australia-wide and shipped internationally, with a Certificate of Analysis and Safety Data Sheet against the batch supplied.
