The HyproJETX6 is a powerhouse with improved flow of abrasive material and air in the nozzle and a special design for cutting even the most difficultmaterials. For standard applications, CERATIZIT’s range includes the HyproJET P6. All nozzles are suitable for modern cutting head systems and support automatic centring during assembly. For somematerials to bemachined, water alone is not sufficient as a cutting material. The system then mixes an abrasive, such as garnet or corundum, into the water jet. Particularly with materials such as steel, stone, glass, or composites, abrasives are very efficient helpers. Mathieu Schellenberger, project manager in product development at CERATIZIT said, "They put a lot of strain on the focusing tubes due to erosion. Therefore, when redesigning the HyproJET products, we further improved the wear protection." GRAIN TESTING OFFERS VALUABLE INSIGHTS FOR GROWERS Grain testing is providing growers with an excellent way to measure the nutrients going out the gate during harvest and estimate required replacement rates, giving them a head start on nutrient budgeting for 2023. Incitec Pivot Fertilisers (IPF) Senior Technical Agronomist Jim Laycock said grain testing can be a valuable part of a grower’s toolkit. “While it doesn’t replace the need for a soil test, it can determine what nutrients have been removed from the soil and what remains in the paddock once a crop has been harvested,” Mr Laycock said. “Grain testing also provides valuable insights about potential seed quality andvigour,whichwe expect tobe a challenge for farmers in2023. “Growers can also use the moisture percentage and 1,000 grain weight to help calculate an appropriate seeding rate.” Nutrient Advantage Laboratory Services offers grain testing for wheat, barley, and other cereals, plus canola and pulse crops. The grain testing report includes a plant tissue analysis and insights about moisture percentage, nutrient status and removal and grain weight. Mr Laycock said being able to put an exact figure on the amount of phosphorus in the grain harvested significantly improves recommendations for 2023 nutrient strategies. “Regular soil tests are still important to assess how soil nutrient levels are changing in response to application rates, and to see where individual paddocks are sitting in relation to critical values. However, for situations where paddocks are at optimal Colwell P levels and growers only want to replace the phosphorus removed at harvest, grain testing can be particularly valuable,” Mr Laycock said. “Make grain testing a priority for planning your 2023 winter crop. It will give you a head start on nutrient budgeting, guide potential seedling vigour, and help calculate seeding rates.” There are four easy steps to complete grain testing: - C ollect samples by paddock, crop or area as required. A sample from a couple of paddocks (one high and one low yielding) is ideal. The best insights come from sampling year after year of dedicated monitoring sites. - C ollect approximately 400 grams of threshed seed (no stalks) in a Nutrient Advantage plant tissue test bag. Keep some bags on hand so you can collect a sample in the paddock and label it with the paddock name. Your agronomist can enter it into the Nutrient Advantage system (NA Pro) when back in the office or log the sample in the LabSTREAM app in the paddock. - Y our agronomist will submit the sample to the laboratory and once the lab receives the sample the typical turnaround time for a grain test is less than a week. - O nce the testing is complete you will receive a report, which will include moisture percentage, nutrient results (in mg/kg or % units), important nutrient ratios, 1,000 grain weight (for wheat only), seed zinc and phosphorus contents (for wheat only), and nutrient removal scaled up to 1 t/ha yield.
