Superior Natural Chelation

What Is Chelation?

And How Does It Work?

Chelation refers to a process of encapsulation in which an ion is reacted with another material to form a protective casing. This has the effect of limiting possible negative ionic reactions, thereby maintaining fertiliser in plant available forms and increasing the pH availability window of many elements – promoting efficient nutrient assimilation. Furthermore, chelates neutralise the charge of ions, allowing plant surface charge gradients to be easily overcome and nutrients to be absorbed with low energy expenditure. If you will, imagine a crab claw (chelate) holding a marble (ion) – the word “chelate” is derived from the Greek “khēlḗ” meaning “claw.”

Common chelating molecules include:

EDTA (Ethylene diamine tetracetic acid)
DTPA (Diethylene triamine pentaecetic acid)
HEEDTA (Hydroxyethyl ethylene diamine triacetic acid)
CDTA (Cyclohexane trans 1, 2 diamino tetracetic acid)
EDDHA (Ethylene bis Alpha-imino-2hydroxyphenyl-acetic acid).

These synthetic chelates possess extremely strong binding characteristics, but demonstrate a myriad of negative physiological consequences once inside the plant. They are totally foreign molecules and often require extremely laborious metabolic breakdown from the plant to both cleave the ion from the chelate and expel the foreign substance from its system.

Remember that these synthetic molecules have a very high affinity for fertiliser ions, so once liberated from their initial ion, will scavenge the system for a new one to hold – interrupting internal biology. The plant must then expel these synthetic chelates, or else a protracted cycle of chelation and cleaving will take place, significantly stunting growth.

Due to the energy intensive nature of cleaving ions from these compounds, as well as their large size hampering passage through plant pores, uptake is also often slow and inefficient. Adding to the disaster, these synthetic molecules frequently possess inherent phytotoxic properties. You might be wondering why growers bother with synthetic chelates at all. We do too.

What Is eXo?

And How Does It Work?

Pleasingly, in eXo, Renovum offers a natural and superior solution to these chelation problems. Included in every Renovum product, eXo is an exceedingly effective blend of vastly different classes of natural chelators, each with their own unique benefits that work in tandem to provide unparalleled efficacy. ‍ The constituents of eXo are small, intermediate strength chelators, capably holding ions in a neutrally charged state until absorbed through root or leaf apertures, where they are then easily liberated to be utilised. As an auxiliary, all compounds contained in eXo exert their own internal positive physiological effects once successfully liberated from the encapsulated ion. ‍ As such, in addition to acting as an organic chelator, specific ingredients within eXo successfully sensitise plant membranes for optimal nutrient uptake, improve plant metabolism and enzymatic activity, increase drought tolerance and resistance to environmental stressors, while concurrently strengthening innate immunity. ‍ Furthermore, these components are capable of stimulating endogenous auxin production and enhancing sensitivity to other hormones including gibberellin and cytokinin – magnifying their effect and resulting in enhanced growth. eXo’s natural components also help to stimulate nucleic acid production and cell division, promote the scavenging of free oxygen radicals by acting as an antioxidant and enhancing endogenous production, and may stimulate root growth as well as positively affect root function to exude organic acids – leading to increased nutrient uptake, growth and yield. ‍ Other eXo constituents achieve their positive physiological effects through separate but equally effective pathways. On top of their chelation properties, these active ingredients improve leaf area and chlorophyll density, promote antioxidant accumulation and activity, and once cleaved are digested for energy or assimilated by the plant. ‍ However, the most impressive property of these compounds is that they possess the ability to complex dominantly Xylem dependent elements such as Calcium and Boron into proteinaceous compounds, allowing the plant to deliver these complexes through the Phloem. This allows healthy cell walls and correct fruit morphology to be maintained deeper into periods of moisture stress. Low mobility elements such as Zinc are also internally translocated with a higher efficiency, resulting in improved growth.

Why eXo is Superior Chelation

Synthetic chelates can reduce nutritional deficiencies, but assimilation is hampered by chelate molecule (ligand) size and high binding affinity. Translocation speed is extremely slow compared to eXo.
Plants do not know what to with EDTA and other synthetics once absorbed. They are unnatural compounds with few to no metabolic excretion or breakdown pathway
Synthetic chelates once finally liberated, circulate in the system for extended periods searching for more free ions, particularly Iron to bind to. This wreaks havoc on internal biology and demands energy be diverted from growth.
EDTA and other synthetic chelates are phytotoxic.
eXo constituents are small enough to be assimilated without a breakdown component, providing efficient absorption and a net energy benefit.
eXo constituents possess an intermediate binding capacity. This provides chelated elemental stability prior to uptake, as well as promoting efficient ion cleaving once assimilated.
All ingredients, in addition to being highly effective natural chelators, possess positive physiological effects once liberated from their encapsulated ion. Improving plant growth, immunity and resistance to stressors in their own right.
