| SO4 is the form of sulfur that the plant can take in. The S form of sulfur has to be broken down to SO4 and this is a biological process that takes place in the soil. Different soils determine the availability of this and how soon it can become available. Thiobacillus bacteria populations have to be high to make this conversion happen. Look around at elemental vs sulfate forms of sulfur and you will see. Rule of thumb is the type of sulfur used is based on how close to the crop you are going to apply the sulfur. Basically saying the only form available to the plant is sulfate form of sulfur. Elemental depends on time, temperature and moisture. | |
