90% sulfur pellets

The botanical requirement for sulfur equals or exceeds the requirement for phosphorus. It is an essential nutrient for plant growth, root nodule formation of legumes, and immunity and defense systems. Sulfur deficiency has become widespread in many countries in Europe.[61][62][63] Because atmospheric inputs of sulfur continue to decrease, the deficit in the sulfur input/output is likely to increase unless sulfur fertilizers are used.

Copper sulfate

Copper sulfate is highly soluble in water and therefore is easy to distribute in the environment. Copper in the soil may be from industry, motor vehicle, and architectural materials.[43] According to studies,[citation needed] copper sulfate exists mainly in the surface soil and tends to bind organic matter. The more acidic the soil is, the less binding occurs.

Ferrous Sulfate (iron)

In horticulture it is used for treating iron chlorosis.[20] Although not as rapid-acting as ferric edta, its effects are longer-lasting. It can be mixed with compost and dug into the soil to create a store which can last for years.[21] It is also used as a lawn conditioner,[21] and moss killer.
