GENERAL INFORMATION
SILTBOND is an easy-to-use, high quality granular formulation specially designed for use in soil erosion control and water infiltration applications on irrigated soils and surface irrigated crops. This is achieved through the stabilization of existing soil aggregates. When used as directed, SILTBOND provides the following benefits: increases water infiltration; reduces volume of runoff water; reduces furrow deterioration; reduces crust formation; and, therefore, increases irrigation efficiency. Soil must be loose and friable prior to application. If crust has been formed by previous irrigation or rain, SILTBOND will not reestablish soil structure. SILTBOND has benefits on all soil types; however, the product is less effective on extremely sandy soils. On extremely sloped fields, it is beneficial to use SILTBOND in conjunction with other erosion and runoff control practices. SILTBOND has been tested on a variety of crops and been found safe to use on plants (no phytotoxic effects observed). Rate adjustments can be made during irrigation based on observed results. 1-3 lbs. of SILTBOND per acre applied in irrigation water gives excellent infiltration and erosion control benefits over a wide range of soil conditions.

Application Technique
Apply after seeding, cultivation or other soil disturbance but prior to rainfall or irrigation. Soil should be loose, friable, and in good tilth prior to application. Do not water prior to SILTBOND application, as soil structure will begin to breakdown. If crust has formed as a result of previous irrigation or rain, SILTBOND will not reestablish soil structure. A variety of dry product dispensers have been used to apply SILTBOND into irrigation water. Start SILTBOND application to irrigation water prior to setting water in the furrows. Continue application during the advance phase of the irrigation (time required to reach the end of the furrow). Treatment should be discontinued after the end of the advance phase. Occasionally a repeat dose is required after the advance phase to keep the system free of sediment. SILTBOND can be applied directly to the head of each irrigation furrow so that the applied product dissolves into irrigation flow. Place approximately 1 ounce of SILTBOND per 1,000 ft. of furrow in each row after irrigation water is started. Spread SILTBOND over several feet of furrow starting from
downstream. It is beneficial to split apply product during the irrigation when using this technique. SILTBOND should be metered into strong turbulence at least 100 feet above the first application point, siphon tube, or gated pipe gate to ensure sufficient mixing with irrigation water. If a drop or culvert is unavailable, tins or dams should be placed to create the desired turbulence. Insufficient turbulence will detrimentally affect product performance. SILTBOND application to irrigation water high in suspended sediment may result in sediment deposition in the irrigation ditch. Siphon tube flow rate can be reduced when SILTBOND treated water is applied through small diameter siphon tubes (3/4 inch), especially when irrigation water contains sediment. When SILTBOND  is properly applied, soil will not erode and water infiltration into the soil will be increased. Normal irrigation and tillage practices may need to be adjusted to compensate for these changes.

CONSTRUCTION SITE USE INFORMATION
Dry Application
SILTBOND can be spread onto bare soil using dry material spreaders. The standard rate of application (25 lbs./acre) should be varied based on conditions. Slope, soil conditions and rainfall all effect rate. Use the chart below as a guide. SILTBOND may be mixed with suitable carrier such as gypsum or lime to allow easier and more uniform spreading.
