TAKE A STAND AGAINST PLASTIC QUINFERT ALLOPHOS ™ (patent applied for) • 0.5% N, 7.9% P, 7% S, 23% Ca. Potash blends available • High-analysis nutrients pre-incubated with high allophanecontent subsoil • The allophane binds water-soluble phosphate, in plantavailable form, minimising phosphate leaching and run-off • It also stabilises the soil organic matter, sequesting carbon and greatly reducing CO2 GHG emissions • Reduces maintenance lime requirements by up to 50% • Contains N-vig™ nitrogenated root stimulator Also available: • QUINFERT Algerian RPR V2 and S90 blends Lime, dolomite and potash blends available • QUINFERT ‘PUSH‘ MAP/SOA blends (North Island only) Amazing new fert sequesters soil carbon AND minimises P loss!

The overuse of soluble P fertiliser is by far the largest cause of P run-o and leaching, and therefore of the decline in the quality of Kiwi waterways. Fact 2. Once you have Olsen P levels that are more than a third of the P retention (ASC), application of additional soluble P is very prone to loss to the environment.Fact 3. If you want to build up your soil P in an environmentally-protective way, simply apply R PR. It does not get leached or lost directly in run-o , but releases P in a sustained fashion for plants.Fact 4. There is nothing to lose and everything to gain. RPR-based fertilisers are even cheaper than super-based products as well! Added sulphur bentonite (sulphur 90) is far more e cient than the excess sulphate in super.Fact 5. Following 1-4 above will greatly reduce P run-o and leaching. This should be done before anything else, and the situation reassessed before spending huge amounts of money!Fact 6. It is nonsensical to give in to pressure to install expensive mitigations riparian strips, excessively large wetlands and ‘phosphorus walls’ when you have no idea of their long-term e ectiveness and maintenance costs, and before you have established whether changing to sustained-release RPR is all you need to do!Fact 7. in any case simple fenced-o 3-metre wide grass riparian strips are essentially as e ective and vastly cheaper than more complex strips. Both reduce bacterial and sediment losses. Neither will have any signi cant long-term bene cial e ect (on a whole -farm basis) on soluble P and nitrate-N loss. But grass strips can be harvested in summer to be fed out, to improve P and N cycling.Fact 8. In a nutshell, for maintenance of P levels any genuine RPR (not an RPR/Boucraa mix please!) can be used. Just check the Cd content. For low fertility situations or low rainfall, use a blend of RPR and high-analysis soluble P.Fact 9. For N, rather than granular urea, use prilled urea, sprayed immediately prior to, or during, the spreading with urease inhibitor. Use of N can be literally cut in half with big savings.Fact 10. Potash is more e cient, and must less likely to cause metabolic problems, if applied in small doses 4 times a year, adding up to 50-60% of the total annual amount you are using now. Easy to mix with your prilled urea. Leaching of anions like nitrate will be minimised as well.For more info, email Bert Quin on bert.quin@quinfert.co.nz, or phone 021 427 572, or visit www.quinfert.co.nz Fact 1.
