Effect of basic agrotechnics for physical and hydrophysical properties of soil
Komárková, Markéta ; Doležal, Petr (referee) ; Kameníčková, Ivana (advisor)
In the master’s thesis, we evaluate the impact of different types of soil treatment on the physical and hydro-physical properties of the subsurface layers of soil. The experimental research took place near the town of Šakvice in two chosen areas treated conventionally, i.e. by tillage. The PRP SOL substance was applied to one of the observed areas. Unimpaired soil samples were taken during the vegetation period of the grown crops in the topsoil (10,20 cm) and in the undersoil (30 cm) on 13th May 2009 and on 10th September 2009. The chosen physical parameters of the soil, i.e. the reduced volume mass, the porosity, the distribution of pores, the actual content of water and air, were determined by standard analytical methods. The double-ring infiltration method was used during the field measuring of infiltration. The Philip’s equation and the Philip’s type three-parameter equation were used for the data analysis, serving as a base for estimation of saturated water content Ks. A protractor with a constant gradient was used during laboratory measuring. The results of a year-long research have not shown any major influence of the PRP SOL substance on the physical quality of the subsurface layers of soil in the observed area. On the contrary, the permeability od the soil obtained on the basis of Ks estimation is higher in the area treated by the PRP SOL substance.

The effects of land management on the physical quality of subsurface soil layer
Komárková, Markéta ; Doležal, Petr (referee) ; Kameníčková, Ivana (advisor)
The thesis deals with the influence of soil cultivation on physical quality of the subsurface soil layers (horizons). The experimental research has been conducted nearby Šakvice on two different areas which were both cultivated in an ordinary way, e.g. by tillage. One of the two areas was exposed to PRP SOL subsidiary substance. Undisturbed soil samples were drawn in three different soil depths: 0,1, 0,2 and 0,3 m. Samples were drawn on May 13, 2009 and September 9, 2009 during the vegetation period of the grown crop. The selected physical properties of the soil, e.g. the specific gravity of the soil, porosity, poruses division, actual presence of moisture and air, were assessed using standard analytical methods. The results of a one-year research did not give evidence of a strong effect of the PRP SOL subsidiary substance on the physical quality of the subsurface soil layers.
