Not too easy to set off my local Home Depot fertilizer aisle unless I had a spare grenade lying around, even then 10% Scotts Turf Builder...? Nah I'll just put a rag in a gas can and throw into my local Exxon where they have the propane.Dadtodabone wrote:Lots of fertilizer products contain ammonium nitrate. I believe they are still the most popular and economical way to provide nitrogen for lawn fertilizers. Theoretically you could soak the fertilizer in diesel fuel and the result would be a crude explosive, you'd just need a detonator.ScottDLS wrote:Rural ones might, but it really is quite difficult to set off...

The N-P-K (nitrogen-phosphorus-potassium) numbers on your fertilizer bag tell you the percentages of those elements in the mix. A common lawn mix is 24-2-8. A 30 lb bag yields: N: 24% x 30 lbs = 7.2 lbs. Nitrates, P: 2% x 30 lbs = 0.6 lbs. Phosphorus, K: 8% x 30 lbs = 2.4 lbs. Potassium.
Dissolve the fertilizer in water, use a couple of coffee filters to strain out the non-soluble P & K, boil the water off and the crystalline material left over are your Nitrates. Combine with charcoal and sulfur 75-15-10 for black powder. Mix with a couple of gallons of diesel fuel for ANFO.
