2015/2/3
In November 2004, forest stands in the Tatra National Park (TANAP) were affected by windthrow and in July 2005, the wildfire broke out on a part of the affected area. The objective of this study is to...
A brief overview of the causes, impacts and amelioration of soil water repellency – a review
soil water repellency hydrophobicity agriculture land management water shortages
<
2015/2/3
This article describes the phenomenon of soil water repellency, starting from the fundamental principals of water transport and storage in soil. Soil water repellency is a reduction in the rate of wet...
Using the sensitivity of biomass production to soil water for physiological drought evaluation

<
2015/2/3
The analysis of drought as a phenomenon and the proposal of how to define and quantify the deficiency of water in soil for plants, so called physiological drought, are described. The presented approac...
Soil water regime estimated from the soil water storage monitored in time
ecology classification soil water regime soil water content monitoring soil water storage
<
2015/2/3
During the vegetation season, the water storage in the soil aeration zone is influenced by meteorological phenomena and by the vegetated cover. If the groundwater table is in contact with the soil pro...
A CENTURY 5 model using for estimation of soil organic matter behaviour at predicted climate change
