In recent weeks, we’ve shared with you about six of the seven micronutrients found in our Yield Booster product, which blends the micronutrients with a 12-9-6 fertilizer. The seventh micronutrient, iron, is our focus today.
Iron exists in multiple enzymes and plays a role in plant-based biological activities. Soil tends to naturally possess good iron levels. However, iron present in the soil may not be adequately soluble or available, according to a publication from the International Plant Nutrition Institute. To correct iron solubility problems, producers may manipulate soil pH levels. At a low pH, solubility improves. Bicarbonate ions may also challenge plants from accessing iron. Iron deficiencies tend to present a more imminent risk in soils that lack organic matter.
If assessing iron levels using a tissue analysis, then consider testing young leaves. Because dust resting on leaves may interfere with an iron analysis, the International Plant Nutrition Institute suggests that growers wash or rinse leaves before running an analysis.
Some symptoms can indicate whether iron levels are too high or low. Typically, iron toxicity instances are infrequent, but look for bronzed, striped leaves to indicate toxicity. According to the International Plant Nutrition Institute, a deficiency would cause stunting and young leaves to appear yellow. At greater severity, leaf coloring may change to pale yellow or white.
Crops may have varying responses toward iron. This story from No-Till Farmer explains that soybeans tend to be more susceptible to iron chlorosis than some other crops. Selecting soybean varieties tolerant to iron chlorosis can help to manage the condition.
Applying Yield Booster offers another alternative to ensure that the soil contains adequate micronutrient levels. In this video, John Ortiz of BigYield.us explains options that growers have to apply Yield Booster on their farms.
