“…Furthermore, there were stronger treatment effects compared with experimental effects for the significant drain effluent parameters in the present study compared with Ref. [15], which could probably be explained by different gravel particle size combinations together with geotextiles [24].…”

This field study sought to determine the all-weather surface construction providing the least contaminated runoff and drainage effluent when exposed to moderate to heavy precipitation and different manure loads in horse paddocks during wintertime. Two different combinations of non-woven and woven geotextile together with two gravel fractions of 200 mm were exposed to precipitation and horse manure/urine for two years under two manure regimes (manure removal and manure accumulation). In a simulated rainfall (SR) study, the test areas were also exposed to 50 mm precipitation for 30 min and 15 kg of horse manure under the two manure regimes. Runoff, drainage effluent and leachate flow were measured and sampled for both regimes. The geotextile-gravel construction reduced runoff and drained the test area throughout the two-year period, confirming construction stability and a dry walking surface area at a mean drain flow of 3.65 L m -2 h -1 . The concentrations of total N, total phosphorus (TP), chemical oxygen demand (COD) and total solids (TS) in fluids leaving the test areas in winter were lower than in previous studies, due to lower horse density. The mean drainage concentration of TP, COD and TS was 3.4, 231, 739 mg L -1 , respectively, due to manure removal in the SR study. The TP (1.9 mg L -1 ) concentration in drain fluids was reduced by 47% in the test area consisting of a single geotextile compared with previously reported values (3.6 mg L -1 ). With the paddock designs tested here, non-point pollution from paddocks could be controlled and reduced.

“…These treatments are coir geotextile, agricultural sun shade net (hereafter called “shade net”), and no mulching. Geotextile is a group of woven fabric widely used in association with soil to separate, filter, reinforce, protect, or drain for agricultural, geotechnical, and civil engineering applications (Koerner, ; Boutron et al ., ). Coir geotextile is made of coir fiber that is extracted from the husk of coconut fruit and is used to protect steep slopes and embankment from erosion (Lekha, ; Vishnudas et al ., ).…”

Revegetation of Decomposed Granite Roadcuts in Korea: Developing Digger, Evaluating Cost Effectiveness, and Determining Dimensions of Drilling Holes, Revegetation Species, and Mulching Treatment

2013

Decomposed granite roadcuts are difficult to revegetate after losing the topsoil and vegetation cover. We developed a new drilling machine, Digger, to efficiently drill six holes simultaneously on decomposed granite roadcuts to facilitate revegetation. The Digger consists of a base machine (0.7 m3‐level excavator) and a mounting body with six hydraulic motors instead of a bucket. We tested its performance on two roadcuts in southwest Korea using time‐motion studies, which showed that the Digger can drill 240 m2 of decomposed granite roadcuts daily. The unit cost of the Digger was less than a half of other roadcut stabilization and revegetation techniques in Korea, making the Digger a cost‐effective revegetation technology. Field germination and growth tests were also conducted to identify appropriate diameter and depth of drilling holes, suitable revegetation species, and mulching treatment. We drilled holes with three different diameters and depths, filled the holes with a mixture of plant seeds and cultivated soil, applied mulching treatments (coir geotextile, shade net, and no mulching), and measured the germination and growth results at two field plots after 1 month and 1 year. The results showed that drilling diameter 10 cm and depth 10 cm were large enough to result in better plant germination and growth. Erosion control species, Poa pratensis L. and Eragrostis curvula (Schrad.) Nees, survived and grew better than native woody species. Coir geotextile improved the plant germination and growth. The time‐motion and revegetation results show that the Digger can be a promising technology to restore decomposed granite roadcuts. Copyright © 2013 John Wiley & Sons, Ltd.

“…Adsorption onto geotextiles. To investigate the possible use of geotextiles to retain pesticides in agricultural watersheds, Boutron et al (2009) measured batch adsorption and desorption of diuron, isoproturon, and azoxystrobin onto and from commercially available geotextiles. Similar studies were made of the adsorption and desorption of polyamide, polyester, and polypropylene onto and from polymeric fibers.…”
