Borrechel Fe increases foliar uptake in peach trees

This work was done by the Institute of Agrifood Research and Technology (IRTA) in Lleida, Spain. They used preventive foliar treatment on Merryl O’Henry variety peach trees to compare the micronutrient uptake of Borrechel Fe and an EDTA complexed formulation. Results show higher iron foliar uptake with Borrechel Fe than the control and EDTA.

Peach trees grown in alkaline soils are extremely sensitive to iron chlorosis (i.e. iron deficiency). Two foliar treatments of 0.2 kg Fe/ha were applied in periods of maximum vegetative growth in the first fortnight of May and June. Iron foliar level measurements were taken 8 days after the first application and 7 and 69 days after the second application of fertilizer.

Key takeaways:

• Higher iron foliar levels with Borrechel Fe than control and EDTA
• Long term increased foliar levels with Borrechel Fe
