Compost Manufactured Soils in
Landscape construction
Reducing the need for
harmful floodplains and
farmland soil stripping
activities is the first benefit
of selecting compost
manufactured soils.
The true value comes with
the higher quality topsoil
enriched with organic
matter, nutrients and
calcium.
And since manufactured
topsoil is screened during
production various grades
are available such as
sportsfield turf, lawn or
wetland soils.
Added benefits of moisture
retention for drought and
compaction resistance
Benefits to Municipalities
• Water Conservation
(reduced watering)
• Minimize harmful topsoil
mining practices
(floodplains etc)
• Enhanced Wellfield and
Aquifer Protection
(erosion protection and
pesticide absorption)
• Cost Savings (less costly
turf maintenance)

Maintenance with Compost
Topdressings
Compost
topdressings in
combination with
core aeration can
be used to repair
and enhance
existing turf or
sportsfields
Granulated

Organic Fertilizers
• Granular Organic Fertilizers (dehydrated pelletized poultry manure)
• Organic Topdressings (for turf restoration and maintenance)
• Cost-effective and safe
• Usage leads to reduction in pesticides
Composts as Organic Bio-Fertilizers
taking on increased interest from
Agriculture (especially in light of recent
price increases in chemical fertilizers):
• Research on-going at NSAC,
Fredericton Research Station,
Cavendish and McCain’s Field
Research Stations all provide
confirmation of increased crop yields
from organic inputs
• High-Value Crops in Potato,
Blueberry, Cranberry, Orchard and
Vegetable production transitioning to
organic production
Sustainable Organic Bio-
Fertilizers from Compost
Pelletizing Plant contains dryer, grinders, mixers and pellet dye to pasteurize, compress, and produce granular fertilizer from poultry manure.
Produced in two different grain sizes for turf or agricultural applications
End product fertilizer provides organic matter, nutrients, iron, calcium, lime, and microbial matter to soil for overall soil health.

Introduction
Novel Technology (dehydration) to process compost and
manure feedstocks into organic Dehy-Topdressing or
Bio-Fertilizer for turf, greenhouse and
landscape/horticulture usage.
Objectives
Quantifying and characterizing, the physio-
chemical properties and the horticultural
suitability of compost, manures or agri-food
residues within bio-fertilizer blends
Assess turf and plant growth performance
from Dehy-Topdressing and Bio-Fertilizer
amendments added during trials
Methodology
Acknowledgments
1. The physio-chemical properties (pH, EC,
nutrient content and release mechanisms) will
be tested.
2. A series of greenhouse and field studies at
NSAC (each a RCBD with 4 replicates) will be
conducted.

Study Design
• Green Velvet Lawn Seed Mix (40% Kentucky bluegrass, 40% creeping red fescue, and 20% perennial rye grass)
• Sandy soil
• Four replications per treatment
• Greenhouse with automatic watering system
• Rate of application based on 100 kg N ha-1, assuming 10% of total N from treatment available

Summary
• Plant uptake nitrogen in treated soils was
not associated with greater biomass
yields
• Biomass yield effects were significant for
selected dehydrated top dressing
formulations with lobster shells and
blends of potato sludge and Nutriwave
fines
• Total nitrogen uptake was greatest in

Key Benefits and Characteristics of
Envirem’s
“Dehy-Topdressing (Soil Amendment)”
• Made with 100% “Environmental Sustainable” and “Organic Certified” ingredients.
• Made without reliance on fossil-fuel based resources of Synthetic Chemical fertilizers or non-renewable Peat-based or mineral fertilizer ingredients.
• Lightweight, Odorless formulation.
• Dehy-Topdressing formula containing natural “Composted” sources of organic nutrients and microbial boost for healthy, vibrant lawns.
• Professional quality topdressing that meets or exceeds important landscape/turf performance parameters for organic matter, nutrient release, and pH balance.
• Product should be of appropriate density to ensure bulk fertilizer sacks volume-out and weigh-out within truck transportation to increase economically viable transportation distances and expand market regions.
• Dehy Topdressing product should be of sufficient dryness to suppress seed germination while in storage (important for potential use as a seed-n-feed product).
• Other potential beneficial characteristics that may be important to turf maintenance markets include: – calcium carbonate equivalency (CCE%) which would supplement lime,
– presence of enhanced iron content levels which support dark green foliage colors,
– a dark black color which improve snow/ice melt and may improve early greening,
