What happens here

Three main liquid brine blends are discussed: straight salt brine (23.3% sodium chloride), and an additive blend (e.g., 90/10 mix of 900 gallons of brine to 100 gallons of additive in a 1000-gallon sprayer). Additives typically contain magnesium or calcium chloride. Sodium chloride is endothermic, drawing heat from the environment, and becomes ineffective below approximately 10°F due to lack of ambient heat. Magnesium and calcium chlorides are exothermic, generating their own heat, which allows them to work at much colder temperatures (down to -30°F). It is crucial to measure the *ground temperature*, not air temperature, using a digital thermometer to determine the appropriate blend. If the ground temperature is below 20°F (in Minnesota), an additive blend should be used to ensure effectiveness.

Goal: Select the correct salt brine blend for optimal performance based on ground temperature conditions.

down to safely about 20° F will it work to less absolutely I know there's guys in Minnesota using Straight brine down to zero not something we typically advocate for because straight salt brine has the propensity to get diluted as snow and ice melts and when it dilutes you can have refreezing occur so what we recommend is anything under 20° using a salt brine additive at a rate of 9010 so when I say 9010 what I mean is 90% salt brine 10% brine additive so like on 1,000g spray unit we'll just write this out 1,000g sprayer it would be 900 gallons of brine 100 Gall additive okay all different kinds of additive out there there's tons of different brands most of them are magnesium or calcium chloride based um the reason that's important is because calcium and magnesium are exothermic chlorides meaning that they generate their own heat whereas sodium is an endothermic chloride which means it draws heat from the environment that's why endothermic chlorides don't work to low temperatures that's why you always hear guys talk about how salt stops working at 10° it's because there's no heat in the environment to create that melting process when we introduce an exothermic chloride like calcium or magnesium chloride now we can work to temperatures as low as NE -30° F in fact in our operation we've had standing water puddles at -30 and it has not refrozen so it's very powerful to use those additives in your buy operation at cold temperatures pre-treatment and post- treatment gallons per acre say the same same rates same rates it's just a different blend at those same rates and what about the price what are we looking at yep so so T typically speaking these prices are what what I like to say is that as the contractors we are the experts or or if we're not the experts yet we're going to become the experts we will always put down the right blend in our client's property based on the conditions so to keep things simple in our operation we do not adjust pricing whether we're using Straight brine or 9010 okay we are just always using the right product for the right situation because again in relation to these prices it's fairly immaterial whether your whether your brine costs 15 cents a gallon or 30 cents a gallon I know that's double but it's double on something that's massively lower than what we're charging so it's really over the course of a 30 event season it's not making a huge impact so in our operation we're always blending at the point of use so we are blending based…
