Fertilizer products need to be able to meet the needs of a crop while supporting success of a grower’s operation and land stewardship. While there’s plenty of focus on nitrogen fertilizer management, phosphorus is also an incredibly important nutrient and also one that has environmental consequences if not managed well.
Kerry Cebul, chief executive officer at Ostara, explains that the company’s phosphate fertilizer, Crystal Green, is designed to address these concerns..
A key difference between Crystal Green and other fertilizers is that it is water insoluble, and releases nutrients based on a crops need, he says. Because of this, Crystal Green it stays put where applied until the crop uses it, Cebul says, making it a sustainable, efficient product.
Since Crystal Green is insoluble in water the nutrients are only available to plants when they secrete weak organic acids and break down the fertilizer. This is not a slow release fertilizer — it is released based on crop driven demand, he explains.
Cebul says the product should be placed close to where roots will grow, and can be applied with everything from strip till to in-furrow to see results. He says that the rate can be reduced in comparison to other phosphates while maintaining yield, but that performance benefits of Crystal Green depend on a grower’s management practice.
