Soluble micro granular Sulfur to lower pH of alkaline soils


Sulfur (S) Free 90.0%
Derived from elemental sulfur

Attention: Sulfur dust in air may explode. Do not air convey.

Explosive Limits in Air:
Upper 35 Gr. per Cu. M.
Lower 1400 Gr. Per Cu. M.

Sulfur ignites easily; Eliminate all sources of ignition.

NET WT. 45 LB.

When this sulphur is applied to soils it is processed by soil micro­ organisms to form sulphuric acid. This sulphuric acid in turn supplies the sulphate ion which is taken up by the plant. The acidifying effect of sulphur oxidation in the soil lowers the soil pH and allows uptake of soil nutrients and particularly iron.

We recommend injection directly into the soil of this material 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.

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 dripline. Many trees situated in good soil and open areas will have root systems extending well beyond the dripline. A site judgement and/or a core sample can be made to determine extent of roots.
