Slurry Seal Treatment Types - Los Angeles County, California
A slurry seal is the application of a mixture of water, asphalt emulsion, aggregate (very small crushed rock), and additives to an existing asphalt pavement surface. A slurry seal is similar to a fog seal except the slurry seal has aggregates as part of the mixture. This combined mixture of the emulsion and aggregates represents "slurry."

The objective of this study was to evaluate nitrate leaching for three application rates of pig slurry (50, 100, and 200 Mg ha (-1)) and a control treatment of mineral fertilizer (275 kg N ha (-1)) applied to corn grown in 10 drainage lysimeters. The effects of two irrigation regimes (low vs. high irrigation efficiency) were also analyzed.

Spreading methods – Swarm Hub
The method of slurry or FYM application can impact on the amount of nutrients that are available to the crop. Minimising environmental losses by reducing the surface area of the slurry or by incorporating FYM into the soil where appropriate will increase crop yield from organic manures and reduce inorganic fertiliser requirements.

Slurry Tankers - low application of effluent - Nevada
Application rates are governed by the width of spread, rate of flow, and travel speed. Rates as low as 1mm can easily be achieved using a Nevada RainWave™, due to its wide spread width. Using a splash plate, normal application depths are 3-5mm. Application rate needs to match the soil infiltration rate to avoid ponding and run-off.

Appendix I. Target application rate for slurry spreading
The target application rate is the volume of slurry that is required to be spread per hectare. The maximum recommended rate for the surface application of slurry is 50m 3 /ha, although application rates of 25-30m 3 /ha are generally used.. In order to apply slurry at the desired target application rate it is necessary to calculate the forward speed at which the tractor must travel.
