Long-Term Water Balance Of A Bare Soil With Slope In Chuncheon, South Korea, Mehmet Aydin, Yeong-Sang Jung, Jae E. Yang, Hyun-Il Lee Jan 2014

Long-Term Water Balance Of A Bare Soil With Slope In Chuncheon, South Korea, Mehmet Aydin, Yeong-Sang Jung, Jae E. Yang, Hyun-Il Lee

Turkish Journal of Agriculture and Forestry

Water balance components of a bare soil with slope varying from 5% to 30% in Chuncheon, South Korea, were simulated using the E-DiGOR model, which proposed an interactive way to quantify runoff, drainage, soil water storage, and evaporation. Daily computations were carried out during the period of 1980 to 2009 for the identified soil-topography-climate combination. A strong correlation between measured pan evaporation and calculated potential soil evaporation was observed (R^2 = 63.8%, P < 0.01) based on the monthly data of the past 30 years (hereafter 'long-term'). When examining long-term dynamics of simulated soil evaporation, monthly mean potential and actual soil evaporations ranged from 9.1 and 9.0 mm in December to 110.5 and 75.2 mm in June and July, respectively. The ratio of actual to potential soil evaporation (E_a/E_p) had a close linkage with soil water content. The higher the soil water amount, the greater the E_a/E_p ratio was. A nonlinear relationship between rainfall and surface runoff was obtained at a given slope. Excess surface runoff and subsurface flow (percolation + interflow) occurred throughout the rainy months from July to September, with peaks in July. The ratio of direct surface runoff to rainfall increased with the natural logarithm of slope. The long-term mean annual direct surface runoff and subsurface flow at the maximum slope were 408.1 and 437.6 mm, respectively. Furthermore, mean annual surface runoff from the slope of 30% was approximately 2 times higher than that from the slope of 5%.

Turkish Journal of Agriculture and Forestry

Cereal cyst nematodes (CCNs) are plant parasites that significantly limit global cereal production. The most frequently reported pathogenic species are Heterodera avenae, H. filipjevi, and H. latipons. One of the most cost-effective, environmentally friendly, and easily adopted control measures is the use of genetic host resistance, which maintains nematode populations below the economic damage threshold level. Many effective sources of resistance to CCNs have been identified in cereals; however, their effectiveness and usefulness is dependent on the interaction of the specific putative resistant accession and the CCN pathotype found in a specific region. In this study, 719 wheat lines from …

The experiment factors were doses of nitrogen of 0, 60, 120, and 180 kg N ha^{-1} and microbial preparations of BactoFil B10, Effective Microorganisms EM, and UGmax. The amount of inorganic N in the 0-0.9 m soil layer before potato planting fluctuated from 63.5 to 80.4 kg N ha^{-1}, while after harvest it ranged from 44.4 to 119.7 kg N ha^{-1}. Nitrogen supply from mineralization during potato vegetation ranged from 36.1 to 46.3 kg N ha^{-1}. Each of the applied nitrogen doses caused a …

Imazamox is an herbicide intensively used in the peanut fields of Turkey. Carbon and nitrogen mineralizations were determined at 20 °C to evaluate the effects of the herbicide in soils humidified to 60% and 80% of field capacity (FC) over 45 days. Three doses of this herbicide [recommended dose (RD, 10 mg kg^{-1}), 2× RD, and 4× RD] were added to soils without any previous imazamox application (NI) and to peanut soils with previous applications of imazamox (I). Carbon mineralization, determined by CO2 respiration, at RD of I soil at 80% humidity was higher than that of the other herbicide …
