Calcium & Nitrogen Solutions
Goal: Boost plant health, nutrient uptake, and yield with 100% available calcium and extended-release nitrogen.
Foliar CAL
A foliar-applied calcium solution enriched with micronutrients, vitamins, amino acids, and growth hormones. Designed to be absorbed through leaf tissue and translocated throughout the plant for late-stage support.
Liquid CAL
Highly concentrated, soil-applied liquid calcium that replaces ag lime more effectively and economically. Improves pH, soil structure, nutrient availability, and root health.
N CAL
A powerhouse blend of liquid calcium, slow-release nitrogen, carbon, and micros. Supports long-term fertility and consistent nutrient availability throughout critical growth stages.
Nitros
72% slow-release nitrogen with carbon and micronutrients. Remains active in soil and on leaf tissue for weeks, improving uptake and yield with fewer gallons applied.
Spray Optimization & Tank Mix Support
Goal: Improve spray performance, drift control, chemical effectiveness, and cost efficiency.
Suretec
A complete tank mix enhancer that replaces multiple adjuvants in one. Includes non-ionic surfactant, liquid AMS, drift control, defoamer, crop oil, sticker, and sulfur—all in a highly concentrated, affordable blend.
