CrossOver products are sold through carefully selected regional retail partners. For distribution in your area, please contact us at (800) 850-0527 or via email at firstname.lastname@example.org.
CrossOver is produced in a variety of formulations to fill the needs of agriculture, turf and horticultural markets from its Global Agronomics Center in Sarver, Pennsylvania.
Various prill formulations in appropriate packaging for agriculture, turf and horticulture suit the individual needs of the many different end users. Harsco produces gypsum-enhanced formulations for these three markets where such formulations are recommended.
Products are sold in 1-ton increments:
- 50-lb. bags x 40 bags / pallet
- 1-ton bulk super sacks
- Bulk containers can also be arranged
CrossOver is a unique formulation of plant-available silicon, magnesium and calcium. Compared to calcium, gypsum and limestone products, CrossOver provides significantly better and more comprehensive solutions to correct chemical imbalances, nutrient deficiencies, structural instability and soil toxicity issues associated with alkaline, acidic and sodic soils.
From the soil, it crosses over into the plant to elevate and promote the plant’s natural defense response to abiotic and biotic conditions.
Plant-available silicon, released by CrossOver, plays a key role in activating plant processes that enhance and improve the efficiency and effectiveness of defense response systems under environmental stress conditions and biological attack.
Specifically, silicon can help alleviate salt stress, reduce stress from temperature extremes, promote balanced nutrient availability and transport, add structural strength, improve photosynthetic activity and improve plant defense responses to disease and insects.
Silicon was categorized as a “beneficial substance” by AAPFCO (the Association of American Plant Food Control Officials) in 2013. Silicon is a primary component of CrossOver.
The organization defines a “beneficial substance” as any substance or compound other than primary, secondary and micro plant nutrients that can be demonstrated by scientific research to be beneficial to one or more species of plants when applied to the plant or soil.
Prior to AAPFCO approval, all silicon products were listed on fertilizer labels as a “non-plant food ingredient.” With the designation, manufacturers can now identify qualifying formulations of silicon as a “plant beneficial substance” – an important distinction.
AAPFCO is an organization of fertilizer control officials who are actively engaged in the administration of fertilizer laws and regulations. Its purpose is to promote equitable fertilizer legislation, effective fertilizer sampling and analytical protocols, develop high standards for fertilizer inspection techniques and enforcement practices, adequate labeling, and promote safety standards for the safe and effective use of fertilizers and protection of soil and water resources.
Some scientists believe that plant ecology and physiology have paid inadequate attention to silicon and that it should be categorized as an “essential element.” The reason it is not lies in the interpretation of the word essential.
According to Epstein and Bloom (2005), the plant biological community is still not aware that plants grown in media in the formulation of which silicon is not included are experimental artifacts: such minus-silicon plants do not exist in nature, agriculture or forestry. The situation is exacerbated by the continued reliance on a badly flawed definition of essentiality according to which silicon does not qualify as an essential element. That definition has been criticized, and a new one has been devised (Epstein and Bloom 2005). Since the significance of silicon to plants is so variable, depending on the genotype and a whole raft of environmental conditions, these authors have deemed silicon a “quasi-essential” element. (This designation is appropriate for sodium and possibly other elements as well.)
Harsco Corporation is a diversified, worldwide industrial services and products company with operations at more than 160 locations in over 30 countries. Among its specialties, Harsco is a global leader in providing environmental solutions to steel and metal producers, offering a broad range of commercial applications developed for the beneficial reuse of production by-products. Harsco’s proprietary recovery and extraction process enables the company to produce a high-quality product exceptionally above the industry standard.
Harsco goes to great lengths to ensure our products used for turf and agriculture are safe and environmentally sound. Harsco is aware of and sensitive to the perception of slag-derived fertilizers and soil amendments being associated with the presence of heavy metals.
Harsco’s proprietary process extracts 99.95 percent of all free metallics, meeting drinking water standards. The remaining co-product is a very clean and pure calcium-magnesium-silicate material, which serves as the primary base for all Harsco turf and agricultural products.
