Equi-sorb (ES) is a super absorbent synthetic polymer (SAP) (polymers can be natural or synthetic).
ES, unlike most SAP, the molecules are not salt based (no sodium, potassium or calcium) which is significant as the application of salts to soils will impact the soils chemistry and will eventually impact the productivity of the soils and the ability for plants to grow.
ES can also be effective in dry soil applications as it will hold and keep the moisture in the soil longer.
An advantage of SAP is they once they are distributed into the soils, they will not biodegrade which is beneficial for mud control purposes, allowing the product to work longer. However, it will remain in the soils for a longer amount of time which will increase the drying time of the soils. ES will break down mechanically over the season as the soils are worked; walked on driven over etc. Freeze and thaw cycle will also help break down ES.
Having said that, if for some reason ANYONE NEEDS TO IMMEDIATELY to decompose ES, they simply spray bleach over the application area which will render ES inert.
ES does not dissolve in mud as it is not able to migrate through the soil like some chemicals. The only way for it to migrate outside of the application area is to physically move the soil. If for example there is a SIGNIFICANT wash over the applied soils (enough to erode the soils) wherever the soils are deposited ES will also be deposited.
Equi-sorb works best when things are really messy. The worse the mud, the better it works.
Applying ES is easy, simply spread over top of the impacted area and MIX IN. The product must be mixed into the soils to work. Applying ES to ponded water isn’t the best use of the product as it will soak up the water, but will leave a gel type material in its place.
Equi-sorb is a super absorbent synthetic polymer and will not organically decompose, allowing it to last for a lengthy period of time, but not forever.
For example, if you applied ES in the spring it should be effective on seasonal mud control throughout the year, but you may have to “top up” some areas again in the fall.
