The Challenge

The quality of turf grass is a reflection of the root system that supports the plant. Turfgrass growing conditions are often not conducive to promotion of optimum root system development.

The Science

Many factors influence root development. This document will focus on three key nutritional factors; phosphorus, calcium, and carbon.

Optimum phosphorus nutrition is associated with the quality and quantity of the root system. Natural soil chemistry conditions tend to quickly tie-up conventional phosphate fertilizers into chemical compounds that cannot be assimilated by the plant. Conventional phosphate is often applied in excess to compensate for these undesirable soil chemical reactions.

The role of calcium for cell wall strength and integrity in the plant is well understood. However, the very important role that calcium plays in root growth is often overlooked. Inadequate plant available soluble calcium will severely limit root growth. 

Soluble carbon, or soluble soil humus is critical to proper microbial function in the soil. Adequate microbial activity in the soil directly impacts root development.

The redox Solution

For optimal root development, minimize undesirable chemical reactions with phosphorus. Also, promote phosphorus and calcium solubility through improved soil microbiological activity. Lastly, supplement with plant available calcium when required. Redox has three tools that may be beneficial for improving root development: TurfRx Ca, TurfRx NatureCur, TurfRx C-85 and TurfRx P+.

TurfRx P+

A reacted plant nutrient product high in phosphorus. TurfRx P+ stimulates root growth due to phosphorus and L-amino acid content. TurfRx P+ is highly efficient due to the complexing process that minimizes negative reactions in the soil which tie-up phosphorous. Apply 0.25 - 1 gallon per acre (0.7 - 2.8 oz./1000 ft2) to the root zone or as required for root development.

TurfRx C-85

A reacted plant nutrient product high in potassium and soluble carbon. TurfRx C-85 improves soil microbial activity due to the short, medium, and long-chain soluble carbon content. Apply 3 - 6 pounds per acre (1 - 2 oz./1000 ft2) annually.

TurfRx Ca

A reacted plant nutrient high in calcium. Plants efficiently absorb TurfRx Ca due to the proprietary micro encapsulation technology. Use TurfRx Ca where increased plant available calcium is required. Apply multiple applications of 0.25 - 1 gallon per acre (0.7 - 3 oz./1000 ft2) to the soil during periods of critical calcium requirements as needed.

TurfRx NatureCur

A reacted botanical extract nutrient product from black walnut and willow that stimulates a broad range of antioxidant compounds.
