The effect of different rates and forms of sulphur applied on changes of soil agrochemical properties
A three-year field experiment was conducted from 2000 to 2002 in North-East Poland. Each year three sulphur fertilization rates in the form of sulphate (S-SO2-4) and pure (S-S0) sulphur were applied: 40, 80 and 120 kg/ha. In the soil horizon at the depth of 0-40 cm the triple rate of S- and S-S0) de...

| Summary: | A three-year field experiment was conducted from 2000 to 2002 in North-East Poland. Each year three sulphur fertilization rates in the form of sulphate (S-SO2-4) and pure (S-S0) sulphur were applied: 40, 80 and 120 kg/ha. In the soil horizon at the depth of 0-40 cm the triple rate of S- and S-S0) depressed soil reaction. Acidification of soil caused by S-SO2-4 became evident already in the first year of the study while that resulting from S-S0) application appeared as late as in the third year. The effect of sulphur on soil in the 40-80 cm horizon was irregular. As the sulphur rates increased and the duration of the experiment progressed, sulphates accumulated in soil. In the 0-40 cm soil layer, the increasing rates of sulphur tended to increase the content of N-NH+4. In most objects, the NPK + S fertilization, and especially the single S-SO2-4 treatment, caused an increase in N-NO-3 in both soil layers compared with the NPK fertilized object. The dose of 120 kg/ha S-SO2-4 caused a significant increase in the concentration of available phosphorus in soil in the 0-40 and 40-80 cm layers. |
