Correlation between Fluctuations in Soil Moisture and Changes in Soil Fertility

Popis výsledku v původním jazyce

This paper deals with relationship between fluctuations in soil moisture and changes in soil fertility and with possibility of using organic waste compost (Cp) and mineral fertilizers to reduce negative effects of drought on soil fertility. To demonstrate the effect of drought on soil fertility and method of fertilization on resistance of soil to drought the pot experiment was performed. Three groups of the treatments with different regime of irrigation and fertilization were prepared. The values of soil reaction, loss of ammonium-N and content of P were chosen as indicator of changes in soil fertility. All variants with addition of Cp showed lower amount of ammonium-N loss than variants without. Furth-more addition of Cp had positive effect of increased in content of soil available P. These results suggest that moisture fluctuations had secondary effect; the method of fertilization was the primary influence on content of P in soil. On the other hand the importance of soil moisture fluctuations in plant-soil system and its influence on N ions movement in rhizosphere was confirmed.
