BUNDABERG macadamia growers will be given a masterclass in plant nutrition, in a special Australian Macadamia Society seminar designed to boost production and profits.
Growers will hear how an additional investment in nutrition can result in returns up to ten-fold, when the findings of a recent study are released next week.
The study suggested an investment of $5000 in additional nutrients could yield production increases worth more than $50,000 in a 16hectare, 5000 tree orchard.
Australian Macadamia Society productivity development officer Rob Commens will present the findings. Soil science and nutrition expert Ian Vimpany will speak about the importance of nutrition.
Mr Vimpany said growers should consider each tree on their property as an individual nut-producing factory that required careful monitoring and attention to detail to operate at its full potential.
"The annual cycle for a macadamia tree is very demanding," he said.
"From August to February the flowers set, the rapid growth of nuts and the oil forming process occur.
"Then the tree needs to rebuild its strength to do it all again the following year.
"Skimping on nutrition inputs may set back a tree for several years, not just the next season."
The MacGroup seminars will examine soil chemistry interactions, tree carbohydrate levels throughout the growth stages and cost comparisons of different fertiliser types.
Mr Vimpany worked with the Department of Primary Industries for more than 30 years. He has 20 years experience in macadamia soil nutrition.
Leading growers from across the Bundaberg region will speak about nutrition programs on their properties and share local knowledge.
The Bundaberg Seminar will be held Thursday, December 6, at 397 Phillips Rd, near Kadalba.
