ecoExpert Tips for Wheat

•Get soil tested every 2 years to avoid over/under-fertilization.
•Split Urea application gives 20-25% better nitrogen use efficiency.
•Never apply urea in standing water – it causes nitrogen loss.
•Use neem-coated urea for slow release and reduced losses.
•Combine DAP + ZnSO4 in the same row for better root zone availability.
