Southern Ag Stump Remover, manufactured by Southern Ag, is an effective wood decomposition accelerator designed to speed the natural decomposition of tree stumps, allowing them to break down faster and more completely without heavy equipment, chemicals that harm surrounding soil, or back-breaking labor.

Unlike products that burn or chemically dissolve stumps, this stump remover works with nature rather than against it. The product contains potassium nitrate, a compound that plays a critical role in decomposition by balancing the ratio of carbon and nitrogen in wood.

Instead of waiting many years for a stump to rot naturally, this product helps jump-start the biological process, reducing the stump to soft, decaying wood that can be removed or left to decompose completely over time.

Southern Ag Stump Remover is an effective, affordable, and homeowner-friendly solution for speeding up the natural decay of unwanted tree stumps. By balancing the carbon-to-nitrogen ratio inside the wood and stimulating beneficial microbial activity, it transforms hard, stubborn stumps into soft, decomposing material that’s easy to remove over time. With simple application steps, flexible timing, and minimal impact on surrounding landscapes, it’s an ideal alternative to expensive grinding or excavation.

Tools Needed

You will need a drill with a 1-inch bit to create the required holes, a measuring tape or ruler to ensure proper depth and placement, and a scale or scoop to measure about 1/4 pound of product per hole.

You will also need a water source, such as a hose or watering can, to fill the holes after adding the product.

If you plan to burn the stump, additional items include kerosene or fuel oil, a long torch, safety glasses, and a fire extinguisher or water source for safety.

How to Use

  • Step 1: For stumps up to 1 foot in diameter, drill a 1-inch hole in the center about 6–8 inches deep, and a slanted 1-inch side hole about 3 inches below the top connecting to the bottom of the first hole. For larger stumps, drill multiple sets of holes (1–2 feet: up to 3 sets; 2–3 feet: up to 7 sets). Pour about 1/4 lb. of Southern Ag Stump Remover in each hole. 
  • Step 2: Fill each hole with water. Allow the product to work for at least 6 weeks, soaking the stump occasionally if rainfall is infrequent.
  • Step 3: After decomposition, manually remove the stump, or to burn, fill the holes with kerosene or fuel oil, let it absorb, then carefully ignite with a long torch while wearing safety glasses and following local fire regulations.

Where to Use

Southern Ag Stump Remover can only be used on stumps.

When to Use

Use anytime you need to accelerate the decay of tree stumps, especially after a tree has been cut down, when you want to clear your yard for replanting, or before manual removal or controlled burning.

Safety Information
