K-Builder – With 50% Slow Release Nitrogen

Liquid fertilizer solution with 50% slow-release Nitrogen

  • Easy to handle and store
  • Low salt index
  • Improves winter hardiness
  • Compatible with technical materials
  • High potassium formula
  • No chlorides

K-Builder’s 7-0.9-17 Prescription

K-Builder is powered by the most soluble and safe form of potassium available, Potassium Carbonate. Unlike other conventional grade products, K-Builder does not contain any chlorides that are harmful to the soils. Chlorides build up salts over time and inhibit turf and plant growth, damaging roots and causing low levels of burn, not visible to the eye which impede nutrient uptake. K-Builder immediately penetrates leaf tissue, quickly dispersing potassium throughout the plant, increasing drought tolerance and carbohydrates needed for withstanding winter’s harsh temperatures.

K-Builder also contains our proprietary Smart N that guaranties K absorption because of its adhesive qualities and “stick-to-it-ness” on leaf tissue and soil particles.

Second in importance only to nitrogen, potassium is key in proper plant growth.

POTASSIUM PLAYS A MAJOR ROLE IN OSMO-REGULATION

  • Improves Drought & Heat Tolerance
  • Regulates Stomata
  • Essential for ATP Production
  • Immediately Penetrates Leaf Tissue
  • Improves Winter Hardiness
  • Increases Water and Nutrient Uptake

RESPONSIBLE FOR EVERY STEP IN PROTEIN SYNTHESIS – ACTIVATION OF PROTEINS

  • Essential in Starch Synthesis
  • Triggers Activation of Enzymes – ATP
  • Better Plant Performance
  • Boosts Plant Carbohydrate Production
  • Important Energy Source for Many Plant Processes
  • Improved Cell Structure

LOWEST SALT INDEX OF ANY POTASSIUM SOURCE TRANSLATES INTO SAFETY

  • Low in Salinity, Making it a Remarkably Effective and Safe Source of Potassium
  • No Chlorides = No Excess Salinity
