Plant litter

Ebook "Plant litter: Decomposition, humus formation, carbon sequestration (Third edition)" gives some new aspects on decomposition that to some of us may be controversial. Thus, the fact that we emphasize the dominant role of microorganisms in the process may be disturbing to many readers, as well as the strong emphasis we give to the fact that humus layers actually do grow over millennia and that at a considerable rate, and thus really sequester e.g. C and N. This book is based primarily on data and conclusions made from field studies.

Ebook "Plant-plant allelopathic interactions II: Laboratory bioassays for water-soluble compounds with an emphasis on phenolic acids" presents detailed descriptions and analyses of the underlying features, issues and suppositions associated with seed and seedling laboratory bioassays presented in a previous volume. It is, however, broader in scope and substance in that the information provided is relevant to all water-soluble compounds released to soil by putative allelopathic living plants and their litter and residues.

Ebook "Plant litter: Decomposition, humus formation, carbon sequestration" gives basic facts about litter decomposition studies, which are of guidance for scientists who start studies. Since the publication of the third edition, there has been quite a development not only in the field of litter decomposition but also in supporting branches of science, which are important for fruitful work on and understanding of decomposition of plant litter and sequestration of carbon.

Ebook "Biology, productivity and bioenergy of timber-yielding plants: An experimental technology" deals with the characterization of the vegetation, morphology, phenological development, biomass production (leaf, litter, wood), and bioenergy of some timber-yielding species of Northeast Mexico, which will serve as a guide to study timber-yielding plants in the native vegetation of Tamaulipan thornscrub and experimental plantations.

Evaluation of the spatial distribution of 2 ecologically similar, but different, in terms of their spatial ranges, earthworm species, D. octaedra and D. attemsi, in the belt forests of northwestern Caucasus were based on our own natural data and using geographic information system (GIS) modeling of modern potential distributions. The quantitative records of earthworms were collected in beech, deciduous, dark coniferous, coniferous-deciduous, and pine forests (1028 geographic locations).

The objectives of the study were to determine the effect of three compost types i.e. Accra compost and recycling plant (ACARP) compost; decentralised compost (DeCo) and composted deep litter chicken manure (CDLCM) on heavy metals concentrations in roselle (Hibiscus sabdariffa L.) and jute mallow (Corchorus olitorius L.) and the health risk of these vegetables to adults and children.

The present study was to determine the conversion of six different solid waste materials viz. kitchen waste, paddy straw, leaf litters, Azolla plant, Cyathula plant and mixed sawdust from local mills into vermicompost and their yield potential by using earthworm species Eisenia foetida. 5 kg dry weight of each waste material were mixed with cow dung and allowed to undergo decomposition. The maximum yield of vermicompost were recorded from the leaf litters (3.937 kg dry wt.) followed by Azolla plant (3.655 kg dry wt.). The lowest vermicompost yield was recorded from Cyathula plant (2.

The study was carried out at school of forestry and environment nursery, Allahabad, Uttar Pradesh. An eight year old plantation of clone of G-48 of Poplar (Populus deltoids) was selected. The leaf litter fall we found that the decomposition of poplar leaf litter is very slow; this has detrimental physical effect on wheat intercrop. Plant height, numbers of leaves/ plant, fresh wt. of root (g) dry wt. of root (g), numbers of tiller/plants, fresh wt. of shoot (g), dry wt.

The eastern Mediterranean region is one of the main areas of the Mediterranean vegetation containing Calabrian cluster pine (Pinus brutia Ten., Pinaceae) forests and terebinth (Pistacia terebinthus L., Anacardiaceae) communities. This study was carried out with the leaves, shoots, leaf litters, and soils of Calabrian cluster pine and terebinth growing on both marl and conglomerate substrata in the eastern Mediterranean region (Turkey) to determine average C, N, P and K contents, and the amounts of humic and fulvic acid in these plant soils.

Plant litter decomposition is controlled by both biotic and abiotic factors. It has been widely hypothesized that litter quality and climatic and soil conditions regulate decomposition. The present study examined the decomposition of native forest tree litter on 2 aspects (the north and the south) and at 3 altitudes (top, middle, and bottom) on each aspect in Artvin province to determine the influence of litter quality, microclimate, and soil characteristics on the rate of decomposition.

The treaty, called the Stockholm Convention on Persistent Organic Pollutants, is a major achievement. It starts by immediately targeting 12 particularly toxic POPs for reduc- tion and eventual elimination. More importantly, it sets up a system for tackling additional chemicals identified as unacceptably hazardous. It recognizes that a special effort may sometimes be needed to phase out certain chemicals for certain uses and seeks to ensure that this effort is made. It also channels resources into cleaning up the existing stockpiles and dumps of POPs that litter the world’s landscape.

Forests cover about 30 percent of total land area, but they store about 50 percent of the Earth’s terrestrial carbon (1,150 GtC) in plant biomass, litter and debris, or in the soil. About 20 percent of total GHG emissions are caused by deforestation and land use changes but in tropical regions emissions attributable to land clearance are much higher, up to 40 percent of national totals. Reducing deforestation and degradation (REDD) is the forest mitigation option with the largest potential for maintaining carbon stocks in standing forests over the short term.
