Enhances Tolerance to Abiotic Stresses

enhances tolerance to antibiotic stressesFor a plant to develop and mature it must overcome environmental stress. CrossOver, a highly refined, calcium and magnesium silicate soil amendment, targets the plant’s ability to do just that.  As its principal component silicon is absorbed by the plant it “crosses over” from its involvement in soil geochemical reactions, becoming an active participant in numerous plant biological processes that enhance the crop’s ability to resist and tolerate environmental - otherwise known as abiotic - stress.  Environmental factors that constitute abiotic stress include heat, cold, drought, high soil salt levels, heavy metals and ultraviolet rays.  Ag, horticultural crops and turf are frequently exposed to such stress reducing yields and plant health.

Failing to provide silicon in ample supply produces plants that are silicon deficient and weakened; preventing them from attaining their full genetic potential. 

Silicon released from CrossOver and absorbed by plant acts as a defense mediator, influencing the amplitude, timing and extent of plant defense signals and responses to stress conditions.  And a plant that can defend itself against stress is one that will, in fact, be able to reach its full genetic potential.   

Restores Optimum Soil Structure

When compared to calcium, gypsum and limestone products, CrossOver’s mineral constituents offer a significantly better and more comprehensive set of geochemical solutions.

Silicon’s soil activity can help to correct chemical imbalances, nutrient deficiencies, structural instability and ion toxicity associated with low pH, salt-affected and high pH sodic soils.

CrossOver also contains enough calcium to satisfy best practices designed to address calcium nutrient requirements and to initiate soil modification through calcium substitution for sodium and other cations present on the surface of soil particles.

Unlock Phosphorus in the soil

Phosphorus (P) is a necessary element for plant growth, metabolism and reproduction and is a limiting factor to plant productivity on an estimated 40% of the world’s arable soil. However, soluble phosphates, used in the majority of fertilizers can quickly form insoluble complexes with metals, minerals, soil particles and organic matter. As a result, up to 80% of applied phosphorus is rendered potentially unavailable for plant uptake.

Silicate anions released into the soil profile following CrossOver applications are particularly effective in establishing processes that decrease fixation of orthophosphate ions in soils, resulting in improved levels of soluble phosphorus for plant uptake.

Independent Research

For decades, the modes-of-action and benefits of silicon use in agriculture, turf, and horticulture have been suggested and validated by researchers worldwide. We are accumulating links to public domain published work that reflect the results of investigations on silicon activity in the soil as well as in planta.


Prof. Lawrence Datnoff, of the Louisiana State University Ag Center, discusses the benefits of Soluble Silicon in plant health and growth.
