SRP Sustain products are a high quality natural organic fertiliser blend of soft rock phosphate, biology, gypsum and sulphur. These blends are mainly made for aerial applications but we have airseeder and powder blends.
The aerial 4-12mm granules are made up of milled sub 2mm minerals and their larger size makes transport, handle, store and spreading easier.
The Sustain blends offers cheaper sustainable alternatives to Single Super (SSP) providing good levels of plant available phosphorous, sulphur and calcium. The phosphorous is in a form where it doesn’t lock up in your soils and the biology and sulphur help to make the phosphate rock reactive.
The Sustain blends can meet organic or sustainable input requirements for cropping, pastoral and horticultural applications.
Available in aerial 4-12mm granulaes, sub 2mm powdered form or 2-4mm air-seeder grade granule. Packaging options are Bulk or bulkbags.
