“…In previous research, ridge and furrow planting has often been shown to lead to greater leaching of solutes than the flat system (Lehrsch et al ., ; Alletto et al ., ; Kettering et al ., ). However, certain application procedures might reduce leaching in ridged fields more than in flat fields (Ressler et al ., ; Hatfield et al ., ; Jaynes & Swan, ).…”

“…Growing evidence suggests that ridge and furrow systems might be vulnerable to solute leaching (Lehrsch et al, 2000;Alletto et al, 2010;Kettering et al, 2013). Experimentally, solutes have been applied to ridges and furrows of potato fields to determine the depth of solute penetration in different areas of the soil (Smelt et al, 1981;Kung, 1988;Leistra & Boesten, 2010a).…”

Summary We compared water and solute movement between a ridge and furrow geometry and that of flat soil with a mathematical model. We focused on the effects of two physical processes: root water uptake and pond formation on the soil surface. The mathematical model describes the interaction between solute transport, water movement and surface pond depth. Numerical simulations were used to determine how solutes of varying mobility and rates of degradation penetrated into the two soil geometries over a growing season. Both the ridge and furrow or flat soil geometries could reduce solute leaching, but this depended on several factors. Rain immediately after a solute application was a key factor in determining solute penetration into soil. In cases with delayed rain after a solute application, solutes in ridge and furrow geometries collected adjacent to the root system, resulting in reduced solute penetration compared to the flat soil geometry. In contrast, substantial rain immediately after a solute application resulted in ponding where water infiltration acted as the dominant transport mechanism. This resulted in increased solute penetration in the ridge and furrow geometry compared to the flat soil geometry. Highlights We studied solute movement controlled by ponding in ridge and furrow and flat fields. We found the ridged soil could impede or increase leaching compared to the flat soil. Solute hot‐spots formed in ridge and furrow soil because of root water uptake. Time between solute application and rainfall is a key factor for solute penetration.

A better understanding of nitrogen (N) diffusion and transformation in soils could reveal the capacity of the biological inorganic N and improve the efficiency of N fertilizers. A field micro-plot experiment was carried out to study the effects of fertilization methods (mixed uniformly with 12 cm top soil, placed in holes at a 12-cm depth, or placed in furrows at a 12-cm depth) and forms of N fertilizers (urea and ammonium phosphate) on the dynamics of soil N's vertical diffusion and horizontal migration in red-yellow soil. The soil inorganic N ( was greater than that from mixed or furrow applications. Under point placement, the migration of soil inorganic N in urea and ammonium phosphate treatments occurred in the 6 -15 cm layer at a horizontal distance of 0 -9 cm. However, the nutrient preservation capability of the soil receiving ammonium phosphate was greater than that receiving urea under point deep placement. Thus, point deep placement had a tendency to increase the inorganic N in the soil and reduce inorganic N loss, which probably occurred due to the reduced soil volume with which the N fertilizer was mixed. According to crop growth and fertilizer requirements, the optimized fertilizer placement and N species resulted in a continuously high nutrient supply to crops for 90 d. However, the effects of point deep placement on increasing the N-use efficiency and reducing N loss have to be evaluated under natural field conditions.

“…More recently, the German/Korean cooperation project TERRECO identified the Haean catchment to be most suitable and representative for investigating impacts of intensive agricultural management in Korea on ecosystem services and on the environment. Several studies have been conducted in the Haean catchment, which mainly focused on site measurements of GHG emissions and crop nitrogen cycling (Berger et al, 2013a(Berger et al, , 2013bJung et al, 2014;Kettering et al, 2013) as well as simulations of soil and catchment hydrology including erosion Kim et al, 2014;Ruidisch et al, 2013). These studies already pointed out that current agricultural management practices pose several risks on the environment in the study area and downstream regions.…”
