Sustainable Management of Salt and Sodic Affected Fairways

CrossOver G Turf represents combination of a highly refined, calcium and magnesium silicate amendment
and gypsum in granular form. Application of CrossOver G Turf results in the effective release of silicate and
sulfate anions -- two highly active and versatile mineral constituents that offer professional turfgrass managers
complimentary sets of biogeochemical solutions that are well suited for use on fine textured salt and sodic
affected fairways that are prone to seasonal abiotic stresses.

Treating Salt-Affected Fine Textured Soils
When compared to calcium, gypsum and limestone products, CrossOver G Turf’s mineral constituents offer a significantly better and more comprehensive set of geochemical solutions to correct chemical imbalances,
nutrient deficiencies, structural instability (deflocculation) and ion toxicity issues associated with low pH, salt-affected and high pH sodic soils.

CrossOver® G products are gypsum-enhanced and produced with high-quality, plant available, soluble silicon in the form of monosilicic acid. Plants can only absorb silicon (Si) in the form of (H4SiO4). CrossOver’s proprietary formulation enables users to take advantage of soil amending properties while building plant-available silicon reservoirs for season-long requirements.

Crossover G Turf Spec Sheet
Crossover Turf Spec Sheet


Enhances Soil Stability:  Acts as a superior soil conditioner compared to calcium, lime and gypsum products

Increases Phos Availability: Can aid in unlocking tied-up phosphorous, keeping it plant available and ready for turf uptake, critical in sensitive watershed areas and during fertilizer black-out dates

Improves Nutrient Efficiency: Promotes nutrient use efficiency in the plant

Increases Photosynthesis: Activates improved respiratory and photosynthetic processes

Elevates Stress Tolerance: Prepares the plant’s auto-defense mechanisms against biotic and abiotic stresses and minimizes their effects.

Improves Soil Structure: Effectively stabilizes both low and high pH soils

Helps Prevent Metal Toxicity: Helps to immobilize toxic elements in the soil and limits uptake by the plants

Helps Prevent Sodium Toxicity: Limits sodium root absorption and transport from roots to shoots

Abiotic and biotic stresses

From uncooperative weather to fungal attacks on fairways and greens, turfgrass needs to hold up to a number of stresses. Silicon plays an active role in plant processes that enhance and improve the efficiency and effectiveness of defense response systems under environmental stress conditions and biological attack.

Stress responses improved by CrossOver’s silicon include:
    Alleviation of salt stress
    Reduction of drought stress and heat stress
    Promotion of balanced nutrient availability and transport
    Improvement in plant structural integrity
    Increased photosynthetic activity

Soil modification

Application of CrossOver G Turf initiates the release of monosilicic acid in the soil solution. As concentrations of monosilicic acid increase, polymerization reactions result in unique silicon-rich inner-sphere complexes being
adsorbed at soil surfaces. These silicate-based soil surface complexes that improve flocculation and agglomeration of dispersed clay particles.

Soil stabilization

The silicon in CrossOver goes beyond the effects of calcium cations, adding a new dimension to soil stabilization.

Long term soil stabilization occurs in soils when calcium ions chemically react with soluble silica (monosilicic acid) and alumina to form calciumsilicate-hydrates (CSH) and calcium-alumino-hydrate (CAH) polymer gels
that function as “binders” between soil particle surfaces.

These hydrated gels bind the soil particles together to form insoluble calcium silicates and establish starting points for enhanced soil particle flocculation and inter-particle crystal matrix formation.

Calcium cations help promote flocculation, but the combination of silicon-based geopolymers and calcium form a much stronger attraction between solid particles than calcium alone. Further, compared to calcium alone, CSH (high pH) or HAS (acidic conditions) in combination with cationic calcium is far less susceptible to reversal should salt or acidic conditions return.
