Driving efficiency in macadamia nutrition with flexible fertiliser strategies
YaraRega helps macadamia growers improve nutrient efficiency and operational flexibility through fertigation or dry application, supporting consistent tree performance, productivity, and seasonal nutrient management .
growth, can be adapted to meet N & K demand & used in combination with YaraLiva Calcium Nitrate to meet high Ca demand periods. However, what sets YaraRega apart is its ver- satility. In addition to fertigation, it can also be applied as a dry fertiliser (surface spread) and in- corporated through rainfall or irrigation. This dual application capability gives growers the flexibility to adapt to changing seasonal conditions, infra- structure constraints or labour availability, with- out needing to switch products or compromise on nutritional balance. From an operational perspective, this flexibil- ity translates to real efficiency gains. Growers can streamline their fertiliser programs, reduce hand- ling complexity, and align applications more closely with crop demand. During peak periods such as spring flush or nut fill, this can be particularly valu- able in ensuring timely nutrient supply without add- ing pressure to already busy operations. In a production system where margins are in- creasingly influenced by input efficiency and oper- ational execution, having fertiliser options that are both high-performing and easy to use is critical. By combining solubility, balanced nutrition and application flexibility, YaraRega offers a prac- tical solution for macadamia growers looking to
Macadamia production is built on consistency. Con- sistent nutrition and irrigation management, con- sistent soil and tree health, consistent pest and disease management and ultimately leading to consistent yield and quality. But as input costs, labour availabil- ity, and operational complexity increase, growers are looking for smarter, more efficient ways to deliver that nutrition without compromising performance. Macadamias have a broad demand for key nutri- ents including nitrogen, phosphorus, and potassium, alongside important micronutrients such as calcium, boron, magnesium, and zinc. With multiple vegetative flushes throughout the year and increasing demand periods during flowering, early kernel development and oil accumulation, timing and delivery of these nutrients is critical to achieving optimal results. This is where fertiliser efficiency and flexibility be- come increasingly important. YaraRega has been developed to simplify nutrient delivery while maintaining high performance. This highly soluble NPK fertiliser can be applied through various fertigation systems, allowing nutrients to
be delivered directly into the ac- tive root zone. The most effective fertigation strategies are typically based on matching nutrient applica- tions with tree phenology, little and often, rather than calendar based dosing. Fertigation using YaraRega feeds roots during periods of active
