Abstract

Influence of soil type on statistical characteristics and graphical results interpretation of the water storage distribution monitoring along the vertical of the soil profile

Highlights

  • The retention capacity and potential of water in the soil affects the water regime of the landscape (Tall and Gomboš, 2013)

  • The results show that the largest winter soil water storage increase is in the clay soil profile of Senné

  • In the Somotor locality at the end of July and in the middle of August, the entire soil profile was in a moisture state below the wilting point

Summary

Introduction

The retention capacity and potential of water in the soil affects the water regime of the landscape (Tall and Gomboš, 2013). Retention soil capacity and soil water availability for the crops is different in various soil types (Červeňanská et al, 2016; Červeňanská et al, 2018; Šoltész and Baroková, 2011; Constantin, 2016). To assess the water storage available for plant cover, is conventionally use the following characteristic points of the moisture retention curve (soil-water content), wilting point (WP) representing the value of pF = 4.18, threshold point (TP) representing the value of pF = 3.3, field water capacity (FWC) representing the value of pF = 2.0 to 2.7. Soil moisture on FWC represents the moisture that stays in the soil after draining of gravity water These facts are reflected in the results of moisture regime monitoring (Skalová et al, 2015). The aim of the paper is to show different monitoring results of individual soil types by statistical and graphical methods. The results of monitoring in three localities at the ESL in the extremely dry year of 2015 were selected for the differences presentation
