Runoff loss of pesticides and soil: a comparison between vegetative mulch and plastic mulch in vegetable production systems.
Current vegetable production systems use polyethylene (plastic) mulch and require multiple applications of agrochemicals. During rain events, runoff from vegetable production is enhanced because 50 to 75% of the field is covered with an impervious surface. This study was conducted to quantify off-site movement of soil and pesticides with runoff from tomato (Lycopersicon esculentum Mill.) plots ...
متن کاملUse of vegetative furrows to mitigate copper loads and soil loss in runoff from polyethylene (plastic) mulch vegetable production systems.
The transport of runoff with high copper concentrations and sediment loads into adjacent surface waters can have adverse effects on nontarget organisms as a result of increased turbidity and degraded water quality. Runoff from vegetable production utilizing polyethylene mulch can contain up to 35% of applied copper, a widely used fungicide/bactericide that has adverse effects on aquatic organis...
متن کاملRunoff and soil erosion as affected by plastic mulch in a Hawaiian pineapple ®eld
The effects of plastic mulch in Hawaiian pineapple culture on runoff generation and soil erosion are poorly understood and not covered in the literature. Field rainfall simulation experiments were conducted on an Oxisol commonly used in Hawaii for pineapple production. Four treatments were no cover (hereafter called bare), plastic mulch as the sole cover (plastic), pineapple crowns as the sole ...
متن کاملEffects of film mulch and soil pesticides on nematodes, weeds, and yields of vegetable crops.
Field plots in Tifton loamy sand were treated with various soil pesticides in 1973 and 1974 and either left exposed or covered with biodegradable flint mulch. Test crops were cantaloup, slicing and pickling cucumber, squash, and sweet corn. Overhead sprinkler irrigation was used in 1973, and trickle irrigation under the film mulch was used on sweet corn in 1974. Soil was assayed for nematodes, ...
متن کاملInvestigation of the Gravel Filters and Plastic Mulch Effects in Improving Soil Infiltration and Moisture Storage in Rainwater Harvesting Systems in Steep Lands
In this study, the possibility of using a combination of gravel filters with plastic cover to increase water infiltration and soil moisture storage in rainwater catchment systems was investigated. For this purpose, five treatments (with three replications) including control treatment, vegetation removal with filter, vegetation removal without filter, semi-insulated system with filter, an...
