Phosphorus lability across diverse agricultural contexts with legacy sources

Journal of Environmental Quality, EarlyView.
Abstract The buffering of phosphorus (P) in the landscape delays management outcomes for water quality. If stored in labile form (readily exchangeable and bioavailable), P may readily pollute waters. We studied labile P and its intensity for >600 soils and sediments across seven study locations in the United States. Stocks of labile P were large enough

EFFECT OF VARIOUS STRAW/MANURE RATIOS IN SYSTEMS WITH EARTHWORMS Eisenia fetida ON LETTUCE GROWTH PARAMETERS AND SUBSTRATE QUALITY

Siberian Journal of Life Sciences and Agriculture
Background. At present, there is an increase in demand for natural agricultural products, which is contributing to the development of plant production in artificial ecosystems that function according to the principles of natural cenoses, with a certain ...

EFFECTS OF PEAT AND PEAT-ZEOLITE SUBSTRATES ON QUALITY, GROWTH INDICES OF CUCUMBER SEEDLINGS AND CROP PRODUCTIVITY

Acta Scientiarum Polonorum: Hortorum Cultus, 2019
The objective of this study was to evaluate peat and zeolite mixtures substrates performance on cucumber seedling quality and crop yield. The research was carried out in a greenhouse covered with double polymeric film at the Institute of Horticulture ...

The influence of habitat quality on the foraging strategies of the entomopathogenic nematodes Steinernema carpocapsae and Heterorhabditis megidis [PDF]

, 2010
Entomopathogenic nematodes (EPN) are soil-transmitted parasites and their foraging strategies are believed to range from ‘ambush’ to ‘cruise’ foragers. However, research on their behaviour has not considered the natural habitat of these nematodes.

Soil compaction of peat under the influence of electrokinetic stabilization (EKS) treatment [PDF]

, 2019
This study aims to enhance the properties of peat such as, (shear strength, compressibility, permeability and liquid limit). Peat is considered as one of the problematic soil in construction projects all over the world, which covers about 4% land of the ...

Nutrients and Hydrology Indicate the Driving Mechanisms of Peatland Surface Patterning [PDF]

, 2009
Peatland surface patterning motivates studies that identify underlying structuring mechanisms. Theoretical studies so far suggest that different mechanisms may drive similar types of patterning. The long time span associated with peatland surface pattern

Stabilization of Peat Soil Using Fly Ash, Bottom Ash and Portland Cement: Soil Improvement and Coal Ash Waste Reduction Approach

IOP Conference Series: Earth and Environment, 2020
Peat soil is very compressible, which leads to an excessive settlement. Stabilization of peat soil is the way to improve the engineering properties of peat soil through mixing peat with supplementary cementation materials.

A multi‐proxy record of climate variability during the Loch Lomond Stadial (GS‐1) at Old Buckenham Mere, East England, UK

Journal of Quaternary Science, EarlyView.
ABSTRACT Northwest Europe experienced high‐amplitude climate change at the onset and end of the Younger Dryas (YD; ca 12 800–11 600 cal a BP), a crucial period to develop our understanding of natural climate dynamics. European palaeoclimatological records generally suggest a bipartite structure of the YD, potentially due to a northward retreat of the ...

Disease suppression of potting mixes amended with composted biowaste [PDF]

, 2005
Peat mining destroys valuable nature areas and contributes to the greenhouse effect. This warrants the search for alternatives for peat in potting mixes. Composted biowaste could provide such an alternative.

An appraisal of Indonesia’s immense peat carbon stock using national peatland maps: uncertainties and potential losses from conversion

Carbon Balance and Management, 2017
BackgroundA large proportion of the world’s tropical peatlands occur in Indonesia where rapid conversion and associated losses of carbon, biodiversity and ecosystem services have brought peatland management to the forefront of Indonesia’s climate ...
