Forest woodland ecosystem: An insight into the addition of litter through teak plantation

Tuesday, February 2nd, 2010

A. K. Mani, S. Manivasakan, S. Vijayabaskaran
Teak is an important tree species grown under plantation conditions for timber requirement. Being a deciduous tree, it favours for accelerated nutrient cycling. A field experiment was conducted in an eighteen year old teak plantation at Forest College and Research Institute, Mettupalayam, Tamil Nadu, India to study the litterfall, [...]

Growth, biomass and carbon accumulation among rubber (Hevea brasiliensis), teak

Tuesday, February 2nd, 2010

N. Appuhamy, L. Samarappuli and S. Karunaratne
The study was conducted to compare the biomass accumulation and carbon stocks among rubber, teak and mahogany. Above Ground Biomass of each species were calculated using the allometric models. Mean total tree height of rubber, teak and mahogany were ranging from 0.87 m to 20.32 m, 3.41 m to [...]

Effect of particle size of Coco peat for Greenhouse Tomato (Lycopercicum esculantum

Monday, February 1st, 2010

H.K.M.S. Kumarasinghe1 and D.G.D. Ransimala2

Coco peat is a by product of extraction of fiber from coconut husk. It is 100% natural, biodegradable, fibrous and spongiest material. It has high C: N ratio, therefore it take long period to decompose. Also it has high water holding capacity, approximately 7-9 times its own weight. Coco peat contains [...]

Microbial Fuel Cell (MFC) Technology for Waste water Treatment and Bio energy: Cow dung as a Waste Biomass substrate

Saturday, July 11th, 2009

Microbial fuel cell (MFC) is an electrochemical cell that converts chemical energy into electrical energy through catalytic reactions of microorganisms under anaerobic conditions. MFC consists of an invariant electrode electrolyte system. In the anode, electrons are produced as a result of catabolism in microorganisms consuming organic substrates. These electrons flow through an external circuit to [...]

Wood quality traits in Eucalyptus hybrid in Tamilnadu for pulpwood

Wednesday, March 26th, 2008

Eucalyptus tereticornis is utilized mainly for paper pulp as it possess long fibers and fibers with wide overall diameter and thin walls. This paper elicits information on extent of variability, effect of stand age, order of coppice sprouts relative to the original tree and number of coppice sprouts per stool on wood properties of E. [...]

Litterfall and Nutrient Accretions to Soil in Teak Plantation

Wednesday, March 26th, 2008

In natural forests and manmade protected plantations, nutrient cycling is an important process and it involves various processes within the ecosystem. A considerable amount of nutrients are returned through litterfall in the form of leaves, twigs, bark, flowers, fruits, etc. to the soil and are made available for reabsorption. In order to study the litterfall [...]
