PS3 is your single, comprehensive source for designing and selecting the right materials to address both the physical and chemical properties of soil and site characteristics. It will help you develop holistic, sustainable solutions for cost-effective erosion control, vegetation establishment and subsequent reductions in sediment and other pollutants from leaving disturbed sites and entering receiving water bodies.


Soil testing is the first comprehensive evaluation needed in order to proceed with any erosion control projects to determine proper soil type. Profile PS3 provides access to conduct Free Soil Tests along with directions on proper soil collection for testing. PS3 assists in the interpretation of the soil test and offers prescriptive application rates of various agronomic formulations based on key soil properties such as texture, classification, pH, nutrient levels, organic matter content, electroconductivity, sodium absorption ratio and potentially elevated levels of harmful salts and metals.


Now that you have selected the site specific Prescriptive Agronomic Formulations fertilizers, other agronomic amendments and Erosion Control Products with application rates needed for your site, it is time to calculate how much of each product should be mixed into each hydroseeder tank load and the total amount each product required for your entire jobsite.

This simple calculator will ensure that your hydraulic slurry is proportionately mixed at appropriate rates based on your hydraulic mulch application rate. It allows you to use either Imperial or Metric units to provide calculations in your preferred units of measurement.

Once agronomic Soil Testing has been performed, proper vegetation species selection along with any necessary soil amendments is the next fundamental step. It is necessary to understand the plant species required for sustainable growth and long-term erosion and sediment control. Soil properties, climate, moisture regimes, slope aspect, future land use and a host of other considerations contribute to proper species selection. Profile experts and the PS3 interface can connect you to the necessary soil selection and product recommendation resources to help you select suitable native, turf grass and ornamental plant or seed sources. Access species selection recommendations at the click of a button and quick registration with PS3.


Once soil and basic agronomic considerations have been examined and addressed, next analyze your project site conditions and choose the most appropriate products or technologies.

PS3 helps you analyze site conditions for characteristics such as slope lengths and gradients, ditch and channel flow hydraulics, banks, levees, shorelines, wetlands and more - using state of the art Revised Universal Soil Loss Equation (RUSLE) and US Federal Highway Administration design protocol.


Once appropriate amendments and products have been selected, proper installation practices are critical to the success of any erosion and sediment control project. PS3 provides detailed installation guidelines, application calculators and CAD details for our erosion and sediment control techniques, including Hydraulically-applied Erosion Control Products (HECP), Rolled Erosion Control Products (RECP) and Sediment Retention Fiber Rolls (SRFR).


Finally, it is important to make sure that after the techniques and products have been properly installed, they are inspected and maintained to ensure functionality and compliance with governing environmental regulations. For example, the U.S. Environmental Protection Agency (EPA) National Pollutant Discharge Elimination System (NPDES) Phase II regulations require that all active construction sites be routinely inspected and maintained after each significant precipitation or other potentially damaging event. PS3 provides inspection and maintenance documents for each of the erosion and sediment control disciplines.
