PWD Planting Soil was originally developed by the Philadelphia Water Department as part of a large green infrastructure policy. The benefits of greening an urban environment are Nemours. Trees and plantings absorbe rain water, provide shade, animal and insect habitat, clean the air and beautify the landscape. PWD Planting Soil was designed for urban tree plantings and has since been adopted as a great all-purpose landscape soil. PWD requires blenders to certify their compliance of this mix twice a year. Laurel Valley Soils has been involved with the PWD Green Infrastructure program from inception and has been an approved supplier every year. The performance of this soil is extremely consistent, adhering to a specification which ingredients are blended to meet a very strict set of parameters. LVS PWD Planting Soil is a well-balanced loam soil with a rich dark brown color, is screened to a half inch, and is stored out of the elements in an expansive covered building. Because of our large scale infrastructure and state of the art equipment, we are able to stockpile inventories so that we can provide our soil year round to meet our customers’ needs, whether that be one truck load or a thousand truck loads.
Container Media mixes are designed for landscape applications in both permanent installations and temporary displays, using lightweight or standard weight options. A common application is in large sidewalk or courtyard planters. Our mixes are not designed for commercial production nurseries, however our Container Media blends will support vegetable production and flower and woody ornamental installations contained in regular to large scale planters. Generally light and well-draining, the weight can be adjusted to support plantings of larger and taller sizes.
Aged Mushroom Compost (AMC) is an all-purpose compost for landscapes, gardens, farming, soil reclamation, commercial site work and soil blending. AMC is composted in the same windrows as our Premium Compost. The main difference is that it is not screened and it is not stockpiled in our covered storage structures. This is a great option for large volume budget sensitive projects, as the important nutrient, biological, and organic matter benefits are the same as with our Premium Compost. AMC is made from our standard blend of the highest grade agricultural feedstocks, composted at our state of the art facility and tested regularly to verify and ensure quality and consistency.
Many projects have unique site conditions and landscape design criteria which can require custom soil solutions. We can create most engineered custom blended soils to fit your project’s design and performance requirements and in the absence of a specification we can offer one of our many off the shelf engineered soil options or collaborate to develop a site specific mix. We can make biosoils, rain garden soils, structural soils, light weight soils, planting soils, rootzone sports turf soils, container/planter soils and more.
For Engineers and Landscape Architects looking ahead to incorporate new specifications for future projects, we can also provide guidance and consultation for creating new custom specifications.
Bioretention Soil is designed specifically to absorb, infiltrate, and filter stormwater runoff into the ground where it can safely recharge our groundwater systems and reduce surface flooding. The goal of a bioretention basin is to capture and divert stormwater runoff displaced from impervious surfaces. Well-designed basins also filter out untreated pollutants that otherwise might flow directly into waterways. Many bioretention basins are large in scale and while they can have attractive plantings, these utilitarian designed basins are generally located out of sight, at the low end of a parking lot or downslope from a building or road.
A stormwater management plan is now a requirement with all new construction that creates impervious surfaces. Water must be contained on site or at least slowed down to prevent flooding and pollutant movement. Bioretention basins are part of the building code and are required for most all building projects including renovations and expansions. The understanding and design of these soils is evolving rapidly.
Other industry names used are Bio-Soil, Stormwater Soil, Filter Media, Amended Soil, Engineered Soil.
Garden Soil is the choice for when a little more ‘oomph!’ is needed. Specifically developed with customer input, Garden Soil was designed for raised garden beds and other applications where a more organically rich soil is desired. However, there are unlimited useful applications for this mix. Customers are using it for regular planting beds, finish grading under sod, filling in divots, and topdressing just to name a few. Garden Soil is made from a 70/30 blend of Premium Compost and native loam soil. This richer soil blend has increased fertility and water holding capacity.
Quality soil is the foundation of every great landscape. Our Enriched Topsoil is the highest quality, best performing all-purpose landscape soil, and we ensure unparalleled consistency from load to load, year in and year out. Enriched Topsoil is a well balanced loam soil with a rich dark brown color, is screened to a half inch, and is stored out of the elements in an expansive covered building. Because of our large scale infrastructure and state of the art equipment, we are able to stockpile inventories so that we can provide our soil year round to meet our customers’ needs, whether that be one truck load for a residential landscape or a thousand truck loads for a highway infrastructure project.
Premium Compost is an STA Certified, high quality all-purpose compost for landscapes, gardens, farming, commercial, reclamation, DOT Projects and soil blending. This high end yet practical compost is our go-to workhorse, thanks to its high organic matter content, broad spectrum of slow release nutrients and beneficial microorganisms. We use Premium Compost as a core ingredient in most of our soil blends and it stands on its own as a great topdressing and in situ soil amendment. Premium Compost is made from a blend of the highest grade agricultural feedstocks, composted at our state of the art facility and tested regularly through the US Composting Council’s Seal of Testing Assurance (STA) Program to verify and ensure quality and consistency. Applying compost is the best way to build fertile, productive, and healthy soil.
