The Next Generation of Balanced Crop Nutrition.
SUL4R-PLUS BZ® builds on the proven performance of SUL4R-PLUS with the added power of boron and zinc — two essential micronutrients for enhanced nutrient uptake, root growth and yield potential. Each uniform granule delivers calcium, sulfur, boron and zinc for consistent, season-long performance that strengths crops from the ground up.
- Superior Uniformity
- Better Boron Source
- No Segregation Issues
- Simplified Handling
- Guaranteed Analysis Reliability
Comprehensive nutrition that powers plant growth, quality and yield.
SUL4R-PLUS BZ delivers a powerful combination of two secondary nutrients and two micronutrients for a total of four key essential nutrients — calcium, sulfur, boron and zinc. With controlled release formulation designed for consistency and precision, SUL4R-PLUS BZ keeps plants nourished through every season of growth.
SULFUR
- SUL4R-PLUS has a nutritional value of 16% Sulfur.
- Essential building block for chlorophyll development, protein synthesis and plant metabolism..
- Required by rhizobia bacteria for nitrogen fixation in legume crops.
- Mandatory for plant utilization of nitrate.
- Critical for building nutrient-producing amino acids like cysteine and methionine that boost protein production.
- Essential for producing oils in crops like soybeans and canola.
- Improves flavor, color and yield quality in fruits and vegetables.
CALCIUM
- SUL4R-PLUS has a nutritional value of 18% Calcium.
- Provides structural cell wall support that leads to stronger leaf and stem structures.
- Enhances resistance to environmental stresses like drought, temperature extremes and pests.
- Supports efficient nutrient uptake and transport.
- Required for nodule formation and supports nodule health in legumes.
BORON
- SUL4R-PLUS BZ has a nutritional value of 0.5% Boron.
- Provides structural cell wall support that leads to stronger leaf and stem structures.
- Improves flower formation, pollination, and seed development for higher yields and better crop quality.
- Strengthens cell walls, supporting plant structure and reducing susceptibility to breakage or deformities.
- Enhances carbohydrate metabolism and sugar transport within the plant, promoting energy flow to developing tissues.
- Aids in root elongation and growth, increasing overall nutrient and water uptake.
- Supports efficient nutrient uptake and transport.
- Required for nodule formation and supports nodule health in legumes.
ZINC
- SUL4R-PLUS BZ has a nutritional value of 1.5% Zinc.
- Activates enzymes that regulate plant growth, chlorophyll production, and protein synthesis.
- Encourages strong root and shoot development, leading to healthier early-season growth.
- Supports hormone production that drives flowering, grain fill, and seed development.
- Promotes uniform maturity and improves the visual and nutritional quality of harvested crops.
