Reasons of this shortage are: a rapid decrease of the atmospheric depositions of sulphur, decrese of the sulphur content in mineral fertilizers, a higher consumption of sulphur by more efficient cultivars, especially of rape and wheat, a leap reduction of animal heads and a higher participation of crops demanding sulphur in the crop rotations. It is necessary to balance this decrease by fertilization, so as the current crop yields and quality can be hold. One of the potential sources of sulphur is elementary sulphur, which is seldom used in the Czech Republic. The proportion of straw plowed under and sewage sludge production are increasing. Similarly with other European countries there is an effort to apply sludge directly on agricultural land or to make composts. The presented project should find out the influence of the supply of elementary sulphur on the sulphur availability"@en . . "0"^^ .
