COMPOST HELPS TO CREATE SUSTAINABLE TOPSOIL ON BROWNFIELD SITE
Untitled Document When confronted with the vast expanse of concrete building bases and the shale tip of the long-abandoned coal mine at Tilmanstone in East Kent, Tom La Dell Landscape Architects realised that the topsoil needed for the regeneration of the site had to be created on site. Compost was the only practical and sustainable source of organic matter to mix with the ...

Terram Green Bund System - Robust & efficient landscaping
Installation of new Terram Green Bund System “TGBS” for slope stability and landscape. The project is a natural turf sports pitch in Sheffield which was to be surrounded by an environmentally and ecologically friendly 1.5m high bund. The angle of the bund slopes is approx 45° and their stability was a concern because of the shear strength of the soil used. (A good quality ...

Colonel Danforth trail, Ontario, Canada - Case Study
A section of Toronto, Canada’s scenic Colonel Danforth Park recently underwent a major slope restoration project after a large section of an adjoining 1.5h:lv slope failed. The slope had eroded to the asphalt edge of a neighborhood road (Colonel Danforth Trail) situated at the slope’s crest, making it dangerous for vehicles to travel on the road. Quick action had to be taken if the ...

Compost, manure, Topsoil, and mulch, Understanding the difference
It’s essential to know how to use organic materials to get the most out of your plants while landscaping your yard or setting up a new garden. Organic waste can be efficiently mixed and composted with the help of the waste composting machine. Mulch, compost, and Topsoil are three of the most commonly used materials. It’s essential to consider the differences between ...

Topsoil properties as affected by tillage systems in the rolling pampa region of Argentina
Improved topsoil structural quality is expected under no-till farming, but soil physical constraints can develop under continuous no-till. Our objectives were: to evaluate the properties of loam, silty loam, and silty clay loam soils under various management practices on a regional scale; to clarify the relationship between soil organic matter pools and soil physical properties; and to find a ...

Is Topsoil costing you the Earth?
BROWNFIELD REGENERATION remains key to the government’s plan for creating sustainable communities. However, crucial to brownfield regeneration is the issue of restoring the land to a high quality as quickly and cost effectively as possible. There is also the matter of ensuring that the regeneration process and resutting development is sustainable, given the increasing concern over global warming. ...

High performance vegetated solutions-research synopsis - Case Study
Research objective Measure performance of the Geoweb® (GW) material combined with a turf reinforcement mat (TRM) (integrated system) with topsoil infill and vegetation under varying shear stresses and flow rates to quantify both hydraulic forces and corresponding soil loss. The test consisted of a series of continuous one-hour flows over the GW-TRM system at incrementally increasing ...

Even Sapir Power Station, Jerusalem, Israel - Case Study
Jerusalem, like any growing city, has increasing needs for water, power, and land, but unlike most cities, Jerusalem is the focal point for three of the world’s major religions. In this city of antiquity, balancing urban growth with natural and historical beauty is a continuing challenge. One such challenge came with the construction of the Even Sapir power station. Built on a mountain ...

Effect of loblolly pine root pruning on alley cropped herbage production and tree growth
Tillage to disrupt (prune) tree roots is an intensive practice which could improve herbage productivity at the crop–tree interface by reducing competition for water. We compared tillage effects on 9- to 11-yr-old loblolly pine (Pinus taeda L.) growth and herbage yields of annual ryegrass (Lolium multiflorum Lam.) and pearl millet [Pennisetum glaucum (L.) R. Br.] on a fragipan soil in Arkansas. ...

Modelling Pesticide and Nutrient Transport in the Cameron Highlands, Malaysia Agro-Ecosystems
Cameron Highlands has a long history of intensive horticulture especially vegetable and flower cultivation. This industry uses large amounts of nutrients and pesticides. Several simulation models were used to assess the movement of pesticides and nutrients in relation to agronomic practices in farm plots cultivated with cabbage and chrysanthemum. It was shown that most of the pesticides are ...

Vegetated slopes - case study summary - Case Study
The vegetated slope Protection system Preserving the natural environment with vegetation is a high priority in slope protection solutions. The Geoweb® slope protection system provides a structurally stable environment for topsoil and sustainable vegetation through a structured network of interconnected cells. The system confines and reinforces the vegetated upper soil layer, increasing its ...

Seasonal changes in the performance of a catch crop for mitigating diffuse agricultural pollution
An in situ technology for mitigating diffuse agricultural pollution using catch crops was developed for simultaneously preventing nitrate groundwater pollution, reducing nitrous oxide (N2O) gas emissions, and removing salts from the topsoil. Seasonal changes in the performance of a catch crop were investigated using lysimeters in a full-scale greenhouse experiment with 50 d cultivation of dent ...

The fate of lead at abandoned and active shooting ranges in a boreal pine forest
Changes in leaching, availability, bioaccumulation, and vertical distribution of lead (Pb) in soil 20 years after the cessation of shooting activity were studied by comparing three pine forest sites in southern Finland: an active shooting range, an abandoned shooting range, and a noncontaminated control site. At both shooting ranges, shooting activity had lasted for 20 years, but it had taken ...

Cokriging spatial interpolation of soil water dependent repellency parameters determined with two different tests
The nonlinear behavior of water repellency (WR) with respect to soil water content (g) may be described by curve parameters derived from two widespread methodologies such as the water drop penetration time (WDPT) and molarity of an ethanol droplet (MED) tests. While the former measures WR persistence in terms of the infiltration time of a water drop sitting on the soil surface, the latter ...

An area of topsoil equivalent to 2,700 football pitches would be lost in just 90 mins!
At a 2014 forum held in Rome and organised by the UN Food & Agriculture Organisation (FAO), Maria — Helena Semedo gave a stark warning to all those attending that it takes 1,000 years to generate 3 centimetres of top soil and approximately one-third has been lost. If the present rate of soil degradation continued, all the World’s topsoil would be gone within 60 years. She went to ...

Near-saturated hydraulic properties in the surface layer of a sandy loam soil under conventional and reduced tillage
Information on the quantitative tillage effects on pore space and near-saturated hydraulic characteristics is important to improve decision support systems for soil and environmental management. The purpose of this study was to determine the effect of conventional (CT) and reduced tillage (RT) on water retention and infiltration properties of an Agrudalf sandy loam surface soil under long-term ...

Profitability maps as an input for site-specific management decision making
For over a decade, farmers have been collecting site-specific yield data. Many have formed doubts about this investment because of their inability to directly apply this information as feedback for improving management. The objective of this case-study analysis was to investigate how site-specific decisions can be improved by transforming a long-term multiple-crop yield-map dataset into profit ...
