Sunflower: Apply 200-450 lbs YaraVera® Amidas® 40-0-0/acre depending upon yield expectations, previous crop (nitrogen credit) and soil test. Depending upon cultural practices, apply 50-70% pre-plant with the remainder side dressed. YaraVera® Amidas™ is an excellent source of readily available sulfate sulfur. It is delivered in a 7.3:1 N to S ratio which is ideal for amino acid and protein production. Readily available sulfur is also beneficial to oil production. Consult your agronomist for local recommendations.
