Online Quote Request FormHumates are a very soft coal called leonardite. They're primarily carbon with a lot of trace minerals and they're normally ground quite fine. They provide a lot of good carbons derived from ancient trees or jungle, etc.

Humates come in 2 forms, the dry form and the liquified form. What they do is grind the leanardite to make a dry humate. They can also take those dry ground humates and put that in with various alkalizing substances to make a liquid. The liquid is actually made soluble so it's not just in suspension, but it's soluble liquid humate. We work a lot with soluble liquid humates and when they're made right, they can help supply carbons in the soil. They also stimulate biology and do a lot of good things.

Humates have carbon which causes the soil to have a tendency to rise, humates always want to come up in the soil, always seeking to come to the surface, just like a cork in the water that always wants to float. So what we use dry humates for especially is to carbonize limestone, because  when we put calcium out in the form of limestone, it wants to sink into the soil and as it sinks it goes out of the root zone.

The thing that we've done is use dry humates to mix in with powdered limestone. We use 15 lbs. per ton of dry quarry limestone and we mix that in. It mixes in very easily, it just kind of electromagnetically mixes right in. It turns the white limestone a gray color and we basically have a really nice product because the limestone wants to go down and the carbons up. They get in each other's way, and that allows more time for the biology to break down the limestone and release the calcium out of it. It works out really good. The carbonized limestone works really well to make the calcium more available by giving the microbes more time to digest the limestone.

For most all other applications we're recommending the use of small quantities of liquified humates because they're already soluble and ready to go to work. The dry humates as far as the stimulating effect on biology, it's just not very quick.

We offer humates in 50 lb. bags on pallets and it's very fine stuff that can be mixed with limestone. If you're interested in liquids, you can contact our office for pricing and availability of products.

    Earlier is Better!

    When it comes to getting your fertilizers for the Fall or Spring season, earlier is certainly better. For those of you interested in Florida soft rock phosphate, you probably are aware of the huge backlog and delays we had due to the bad weather down in Florida earlier this year.

    Well, the good news is that right now you can get bulk granular soft rock from Florida with no delays! It is ready and waiting for you! We can’t guarantee it will be that way for much longer as the Fall season is upon us and things tend to get busier. If you are thinking of making an order, earlier is better!

    Our main supplier of pelletized gypsum and lime has a new product that provides the benefits of humic substances with a soluble source of calcium and sulfur in one homogenous pellet. SuperCal Humic blends 15% humic substances (Leonardite) with 85% SuperCal SO4, humic acids and complex carbohydrates. This is available in bulk at $360/ton FOB Gilmore City, IA.
