“…These results demonstrate that the rice straw mat and the soil amendments were effective in reducing both runoff and NPS pollution loads. However, the reductions of nutrient losses in this study were relatively low despite adding the soil amendments (PAM and gypsum) when compared to the reductions of TN 68.3% and TP 53.3% observed by Shin et al (2012), who covered the soil with a similar amount of straw mat (3.1 ton/ha) as used in the present study, but on plots with 3% slope. The differences in results from the present study and that of Shin et al (2012) appear to be due to the slope difference.…”

The differences in results from the present study and that of Shin et al (2012) appear to be due to the slope difference. The nutrient reduction rates achieved in the present study also were low (approximately half as large) compared to the results (about 95% for TN and 97% for TP) from the study by Won et al (2013), which was performed on 28% slope.…”

“…However, the rainfall volume and the runoff reduction rate showed high correlations at the 95% confidence interval and the coefficient of determination R 2 was 0.95 (Figure 3). A similar correlation was achieved between the rainfall volume and the runoff reduction rate in research by Shin et al (2012). Furthermore, the present study was performed under a limited rainfall range due to the relatively short research period and may not sufficiently capture the full impact of the rainfall intensity.…”

We described the effects of straw mat cover and soil amendments on runoff, agricultural non-point source nNPS) pollution and crop yield on sloping alpine fields in Korea. Two sandy loam field plots were prepared. One was a control plot and the other (SPG) was an experimental plot treated with rice straw, polyacrylamide (PAM) and gypsum (rice straw mat (3,300 kg/ha) + PAM (5 kg/ha) + gypsum (1 ton/ha)). Chinese cabbage was cultivated in the plots and seven rainfall-runoff events were monitored during the growing season in 2012. Less runoff and a lower NPS pollution load were measured from the SPG plot, compared to those from the control plot. The SPG plot had 29.4% less runoff and the pollution load was reduced by 86.6% for suspended solids, 34.7% for total nitrogen and 39.1% for total phosphorus. The Chinese cabbage yield at the SPG plot was 39,600 kg/ha, which was about 40% higher than that at the control plot. These results indicated that the SPG treatment could not only reduce runoff and agricultural NPS pollution but also increase crop yield and be a best management practice for sandy loam sloping fields in Korea. © 2016 The Authors. RÉSUMÉNous avons décrit les effets de la couverture du sol par des paillis et des amendements sur le ruissellement, la pollution diffuse et le rendement des cultures sur les champs « alpins » (ie pentus) en Corée. Deux parcelles de terrain de sable limoneux ont été préparées. L'une était une parcelle de contrôle et l'autre (SPG) était une parcelle expérimentale traitée avec de la paille de riz, du polyacrylamide (PAM) et un paillis composite de gypse (3.300 kg/ha de paille de riz + 5 kg/ha de PAM +1 tonne/ha gypse). Le chou chinois a été cultivé dans ces parcelles et sept événements pluie-débit ont été contrôlés au cours de la saison de croissance en 2012. SPG permet un contrôle du ruissellement et de la charge polluante. La parcelle SPG avait 29,4% de moins en ruissellement et la charge de la pollution a été réduite de 86,6% pour les solides en suspension, 34,7% pour l'azote total et 39,1% pour le phosphore total. Le rendement de chou chinois à la parcelle SPG était 39.600 kg/ha, soit environ 40% de plus que la parcelle témoin. Ces résultats indiquent que le traitement SPG pourrait non seulement réduire le ruissellement et la pollution diffuse agricole, mais permettrait une meilleure pratique de gestion pour des champs en pente limono sableux en Corée, tout en augmentant le rendement des cultures.

“…This is different from the summer-rice-winter-wheat rotation in the same most likely generated surface runoff. [36] Based on this study, 53-56% of the rainfall contributed to surface runoff ( Figure 4). Considerable amount of N was lost in runoff with the surface soil nitrate-N as high as 656 mg kg −1 after tomato harvest (Table 2) combined with high precipitation in the summer season when the polyethylene cover was not in use.…”

Nutrient losses from greenhouse vegetable production systems may impair water quality in the Taihu Lake Region of China. We studied the characteristics of nitrogen (N) lost via runoff from greenhouse vegetable systems and strategies for minimizing N entering water bodies. A two-year experiment at a field scale was conducted to monitor N surface runoff. An eco-ditch (148 m(2)) and a low N input paddy field (135 kg N ha⁻¹, 550 m²) were designed to remove N from the surface runoff of a 25 × 50 m greenhouse vegetable field. The greenhouse was not covered from late June to mid-October each year, and runoff occurred multiple times during this period. Annual total N loss in runoff from the greenhouse vegetable site was 25.3 and 33.5 kg ha⁻¹ in 2010 and 2011, respectively. Nitrate-N was the major form of N lost in the runoff. The average runoff volume was 289 mm (varied from 221 to 357 mm), which contained 15.7 (varied from 3.3 to 39.2 mg L⁻¹) mg L⁻¹ total N. The eco-ditch system and the wetland paddy field (WPF) effectively reduced total N discharge; the removal rates reached 49.9% and 58.7% and the average removal capacities were 12.4 g N m⁻² and 4.1 g N m⁻² in 2010 and 2011, respectively. The combined system of the ecological ditch-WPF removed almost 79% total N in the runoff. Ecological ditch or paddy wetland can be a water management option available to growers in this region to economically reduce pollutants in agricultural runoff.

“…In the past few decades, many researchers have focused on the precipitation, topography conditions on the influence of the NPS pollutants migration [24][25][26]. A prediction of potential bioavailable P in the water columns and sediments and their relations with enzymatic hydrolysis was conducted and the spatial variations of phosphorus showed that higher phosphorus content and more intense enzymatic hydrolysis in silty clay finer sediments [27].…”

Abstract:The Sichuan Basin is the main agricultural production area of the upper reaches of the Yangtze River and is also an extremely important ecological area because it is rich in biodiversity and has complex and diverse landscape types. The dominant soil type, purple soil, is prone to rapid soil erosion and weathering processes because it is shallow and rich in phosphorus and other nutrients. Field experiments were conducted to reveal the effects of precipitation and topography characteristics on nonpoint source pollutants from purple soil. The results showed that total phosphorus (TP) load and TP concentration both increased with increasing rainfall amount, and there was an initial time of runoff and sediment yield before runoff generation. Moreover, the TP load generally increased with precipitation intensity as setting a coincident value of rainfall amount; however, the difference between TP load at 30 and 60 mm/h was minimal as was the difference between 90 and 120 mm/h. Similarly, TP concentration increased with increasing precipitation intensity. In terms of topographical conditions, TP load increased with increasing gradient, but began to decline when the gradient was about 20 • , which indicates that 20 • is the critical gradient for TP loss. There was a significant positive correlation between gradient and TP concentration when the gradient was <15 • , whereas the increase in TP concentration slowed as the gradient increased.
