An evaluation of BOOSTER-Mag on processing tomato farming productivity

2017 Agronomy Australia Conference


Calix Limited is developing BOOSTER-Mag™ for application as a low cost and benign foliar spray for agriculture. The product is a concentrated aqueous suspension of mineral derived bio-active magnesium hydroxide (Mg(OH)2). Under the auspices of the Australian Processing Tomato Research Council (APTRC), Calix is working directly with Victorian processing tomato growers to quantify the effect of the product onmarketable yield and fruit quality.

Over the 2015/2016 season, an initial split plot, multi-replicate field evaluation of BOOSTER-Mag™ treatment in field grown processing tomato was undertaken across three different farms in central Victoria. Three BOOSTER-Mag™ treatments were applied at 1.5kg concentrate/ha over a 33 day period approximately coinciding with the grow-out midpoint. The treatments were in addition to the conventional pesticide treatments applied throughout the season according to IMP methodology and agronomist advice. Hand harvest data obtained one week prior to mechanical harvest demonstrated that additional treatment coincided with an increase in the average yield of red and unblemished fruit across all three farms (by 6%) relative to the conventionally farmed controls, an outcome somewhat concomitant with observed reductions in unripe, blossom end-rot and insect affected fruit. The reduction in the yield of insect damaged fruit is difficult to explain by macronutrient augmentation and suggests the additional treatment provided insect pest control.

Calix has developed BOOSTER-Magan easy-to-apply foliar spray that acts as both fertiliser and stimulates a plants natural ability to fight disease and pests. It demonstrably provides a substantial safety, simplicity, sustainability and productivity benefit.

2017 Australian Agronomy Conference

The Australian Agronomy Conference is the meeting place for Agronomists; it supports research and the community of Agronomists by connecting Agronomy communities across Australia to each other.

The theme for the 2017 conference is “Doing more with less”. A central plank of Australia’s productive output is agriculture, worth over AUD$13.6 billion exported annually. Agronomy is key to ensuring that farmland is productive across Australia’s diverse landscapes. Innovation in machinery and precision technologies, plant species and varieties, soil and plant management may allow the agronomist of today to successfully help agricultural producers thrive.
