PIAMON 33-S - Nitrogen Fertiliser with Sulphur Brochure

Environmental protection measures such as flue gas desulphurisation have resulted in sulphur inputs from the atmosphere being reduced to below 10 kg S/ha per year in many areas. Only small quantities (10 to 40 kg S/ha) are released from the soil reserves annually. That is often not sufficient to supply the plant with an adequate level of sulphur. The amount of sulphur in the soil available to the plant may be subject to considerable fluctuations depending on the location and the fertilisation. There is often a sulphur deficiency at times of low mineralisation such as before or at the start of growing.
