Aluminum sulfate for every 10 square feet of soil, advises clemson university cooperative extension. Iron fertilizers iron can be applied as ferrous sulfate or in a chelated form.
The main use of this substance in gardening is to lower the ph of the soil.
Iron sulfate and aluminum sulfate lower soil ph. This speed carries the risk of applying excessive iron or aluminum if you add too much of these products (typically more than 5 pounds per 100 square feet). Like aluminum sulfate, ferrous sulfate also lowers soil ph of alkaline soil rapidly. Iron sulfate to lower soil ph both iron sulfate and aluminium sulphate act faster than elemental sulfur and can significantly reduce ph in as little as three or four weeks;
These include sphagnum peat, elemental sulfur, aluminum sulfate, iron sulfate, acidifying nitrogen, and organic mulches.
Elemental sulfur is available in most garden centers; The are two types of sulfates you can use to lower soil ph: If your lawn is on alkaline soil, the conversion process can lower its ph. One pound of aluminum sulfate or elemental sulfur is equal to about 2 cups.
Applied to soil, it is often ineffective, especially in ph above 7.0, because its iron quickly transforms to fe3+ and precipitates as one of the iron oxides.
Iron sulfate is sold in liquid and dry form. This is why we care about what our soil ph is and why some people take great measures to adjust their soil ph from year to year. Sphagnum peat, elemental sulfur, aluminum sulfate, iron sulfate, acidifying nitrogen, and organic mulches are among them. The cheapest way to lower the soil ph is to add elemental sulfur to the soil.
Use 3 to 6 pounds of iron sulfate per 100 square feet to lower soil ph one unit, using more on heavy soils and less on sandy soils.
Iron sulfate and aluminum sulfate. You should avoid using too much of this substance since it can reduce the soil ph too much, which is unhealthy for the lawn. Soil bacteria change the sulfur to sulfuric acid, lowering the soil ph. What is iron sulfate used for plants?
Spring application and incorporation work best.
Changing ph is not a short order process…but you can drop the ph one point per year by applying 5 lb of 35% ferrous sulfate per 100 square feet now and once again in six months, followed by a soil test, to see what’s happening.

Use about 4 to 6 lb. Iron reduces soil ph and won't stain or burn like other iron products. In my lawn i’m starting out with a ph in the neighborhood of 6.8 to 6.9. Aluminum sulfate and iron sulfate produces the acidity as soon as it dissolves in the soil thus the best for instantly lowering soil ph to acidic.
Of course, this is only a temporary fix, but for at least a short period of time, you've lowered the ph in the root zone to increase plant uptake of the available nutrients, and provide a more favorable environment for microbial activity to increase.
Liquid solutions act faster than granular products. I’d like my ph to get down to 6.5 but i also know that lowering ph more than 0.1 to 0.2 permanently takes a lot of time.

For this reason, most people use these two elements as compared to elemental sulfur.
This handout is just a guide.
Faster than elemental sulfur since they require chemical rather than biological reactions. Add 20 pounds of lime per 100 square feet. If the soil ph is greater than 5.5, apply elemental sulfur (s) to decrease the soil ph to 4.5 (see table 1).
