mulches with increased fumigant retention are a reduction in the amount of fumigant needed for effective pest control, lower emissions, and a decreased buffer zone requirement. Films manufactured by coextrusion containing multilayers with barrier polymers

Water retention was measured in soilless potting media irrigated by capillary mat, flood and drain, drip or overhead sprinkler. Media were amended with wetting agent or hydrophilic polymeric gel. Pots 12 cm high with a volume of 465 cm3 were loose-filled to the top with media. Potted media were wetted overhead with 120 ml water, then pots were randomly assigned to irrigation treatments. Capillary mat irrigation was continuous; other irrigation treatments were applied daily. Water retention was measured by weighing. Irrigation was continued until no further retention was measured. Water retention was significantly affected by irrigation method and medium amendments. Irrigation method followed the order overhead >= drip > flood and drain >= mat. Hydrophilic gel increased water retention, but in contrast to previous results, wetting agent did not, nor was any interaction of gel and wetting agent observed. Retention of water at container capacity, measured in situ at the end of each experiment, was significantly larger than actual retention.

Soil physics studies usually include two complementary aspects: 1) soil solid phase organization; and 2) transport processes. The water retention, Ψ(θ), and hydraulic conductivity curves, K (Ψ) or K (θ), are usually measured to characterize the
