Sulfur ignites easily — eliminate all sources of ignition.

We recommend injection of this material directly into the soil as the speed of oxidation to sulphuric acid depends mainly on the extent of contact between sulphur and the soil. Injection on a grid allows for fine division and wide dispersion into the soil.
|Soil pH||Sandy Soil||Clay Soil|
|7.5||5 lb.||8 lb.|
|8||7 lb.||10 lb.|
|8.5||12 lb.||15 lb.|
Research has shown that unobstructed tree feeder roots tend to be in the top 6″ of soil. Therefore we recommend that the probe or hydraulic needle be inserted no deeper.
Injections should be every 2-1/2 feet square on a grid starting approximately five feet from the trunk and extending beyond the drip line. A site judgment and/or a core sample can be made to determine extent of roots.
