Growing Grasses with Blueberries Corrects Iron Deficiency

A study published in Frontiers in Plant Science showed that growing grasses with blueberry plants could correct signs of iron deficiency at less cost and risk than chemical treatment. The grass intercropping also increased yield and antioxidant content of the berries. Senior study author Dr. José Covarrubias explained that “Grasses — which are well-adapted to poor soils — can provide a sustainable, natural source of iron chelators via their roots when grown alongside fruiting plants. Intercropping with grass species has been shown to improve plant growth and fruit yield in olives, grapes, citrus varieties — and most recently, in blueberries.”
