Although an increasing number of farmers understand the importance of boron to obtain high yields, experts note that farmers prefer to "forget" about this fertilizer in the hope to reduce costs. But such savings are, in the end, turns against manufacturers.
"Bor is especially important for the formation and viability of pollen, which directly affects the yield of all flowering crops, such as canola," says agronomist Natalie wood. "But surprisingly, people know that they need to apply micronutrients, and thus lose sight of the forest, despite the high level of boron deficiency in soils of great Britain."
Symptoms of boron deficiency include stunted growth, deformation of new leaves (edges curl), and older leaves become reddish-purple color. With a shortage of boron plants form a small number of pods and seeds, and the fall in the core of root voids.
According to Ms. wood, farmers often scares potential toxicity of boron.
"Although we need to take this into account, the reality is that the toxicity of boron really occurs only at very high applications. To cause the problem, it would take a few pounds, whereas liquid foliar fertilizers do you apply in grams," she said.
The recommended application rate of boron is 1 liter per hectare, even though farmers are encouraged to increase this number if you have a deficit.
In 2017, 58% of the samples tested oilseeds had a boron deficiency.
In 2018, that number had dropped to 54%. Slowly but surely farmers are beginning to pay more serious attention to this element.
"Awareness rises, but it is clear that there is still outreach to farmers. The introduction of boron into the program spring power gives oilseed rape the best odds on the result and increases the likelihood of higher yields," said Ms. wood.
