If we’re to feed a growing population, agriculture needs to become even more efficient.
Can micronutrients solve a macro problem? “Precision agriculture” – ensuring crops get exactly the mix of nutrients they need to grow well – could help efficiently feed a growing global population. And as an essential element for crop growth, boron has a vital role to play.
Peak farmland?
The world may be approaching the limits of what’s possible with current methods of food production. Global population is expected to rise to nearly ten billion by 2050. Yet projections suggest we will reach “peak agricultural land” – where there’s no more space available for crops and grazing – by around 2040.
Pioneering Resources and Research for the Future of Food Production
Fortunately, developments in science and technology support increasing efficiencies and offer new opportunities in food production. We’re learning more about the importance of micronutrients such as boron—and how to target those micronutrients to enhance the effectiveness of fertilizers.
Precise, efficient use of micronutrients is a key element in protecting the health of soil, supporting sustainable farming, and increasing both the nutrition and yield of crops. For example, without boron, crops don’t grow properly. However, many crops, like coffee, cotton, alfalfa, and grapes, remove significant amounts of boron from the soil. Boron deficiency is a top concern for agriculture professionals worldwide.
However, proper boron supplementation must start with the right product. Refinement and quality control of boron fertilizers is essential to ensure they are soluble (so that plants can use them), cost-effective, and free of harmful impurities.
