The present paper focuses on the point irrigation design for crops and growing vegetables on an experimental area 2432 m2 at Buchel locality, Northern part of Gobi desert in Mongolia. An underground water source (drill hole - well capacity 2 l/s with water temperature 10°C) and electricity were available in the locality of the selected area of 1 ha and 0.2% grade of slope (no map was available). The design of the surface and subsurface point irrigation for an area of 128 m2 is shown together with a brief description of the hydraulic materials used for the development of the original HYBOZAM program, which was programmed in Microsoft...

Field experiments were conducted at the Agricultural Engineering Experimental Farm of The Federal University of Technology, Akure, during 2006/2007 and 2007/2008 seasons to investigate the response of cassava under drip irrigation. The experiment was laid out in a randomised complete block design (RCBD) with three replications. The treatments were based on four different water regimes; with T100 receiving 100% available water (AW), T50 and T25 receiving 50% and 25% of AW and T0 with zero irrigation (control treatment). Disease free stems of the cassava cultivar TMS 91934 were planted at a spacing of 1 m by 1 m. The...

In this study, the effects were investigated of salinity, foliar and soil applications of humic substances on the growth and mineral nutrients uptake of Corn (Hagein, Fardy10), and the comparison was carried out of the soil and foliar applications of humic acid treatments at different NaCl levels. Soil organic contents are one of the most important parts that they directly affect the soil fertility and textures with their complex and heterogenous structures although they occupy a minor percentage of the soil weight. Humic acids are an important soil component that can improve nutrient availability and impact on other important chemical, biological,...
Modelling soil organic carbon changes on arable land under climate change - a case study analysis of the Kočín farm in SlovakiaOriginal Paper

We have estimated soil organic carbon and crop yield changes under distinct climate change scenarios for the Kočín farm in Slovakia. Two regional climate change scenarios, i.e. the A2 and B2 SRES emission scenarios, and a reference climate scenario have been included into the bio-physical process model EPIC to simulate the effects on the topsoil organic carbon stocks and crop yields for the period of 2010-2050. In addition, we have used the data from several fields of the Kočín farm including the soil data, crop rotational and management data as well as topographical data. The topsoil organic carbon stocks show a decreasing trend for the period of...
Assessment of frequency and areal extent of overland flow generation in a forested mountain catchmentOriginal Paper

Soil & Water Res., 2011, 6(1):43-53 | DOI: 10.17221/33/2010-SWR
Short time rainfall and throughfall measurements in the period May-October 2009, and the calculated saturated hydraulic conductivities of soils and isotopic hydrograph separations in August 2009 were used to estimate the frequency of the infiltration excess overland flow generation and the extent of saturated areas producing the saturation excess overland flow in the forested mountain catchment of the Jalovecký Creek, Western Tatra Mountains, northern Slovakia. The rainfall intensities exceeding 0.2 mm per 10 min occurred only in 2-4% of all data measured. Saturated hydraulic conductivities (KS) of soils were calculated by means...
