Yara recommended fertilizers for Calcium
YaraLiva® CALCINIT™15.5-0-0
Table Grapes: Apply 325-650 lbs YaraLiva® Calcinit® 15.5-0-0 19 Ca/acre according to vine age, expected yield, and soil test. Apply 50% N needs prior to bud break and the remainder post-bloom via fertigation. Utilizing YaraLiva® Calcinit® for part or all of the nitrogen needs supplies the crop with fast acting nitrate nitrogen and will provide soluble calcium in proper ratio with nitrate nitrogen. Calcium is important for berry quality and firmness as well as disease resistance. Consult with your agronomist for local recommendations. Wine Grapes: Apply 200-500 lbs YaraLiva® Calcinit® 15.5-0-0 19 Ca/acre according to variety, vine age, expected yield and soil test. Apply 50% N needs prior to bud break and the remainder post-bloom via fertigation. Utilizing YaraLiva® Calcinit® for part or all of the nitrogen needs supplies the crop with fast acting nitrate nitrogen and will provide soluble calcium in proper ratio with nitrate nitrogen. Calcium helps to reduce berry splitting and increases disease resistance. Consult with your agronomist for local recommendations.
