Growth and Biomass Production of Fast Growing Tree Species Treated with Slurry Composting and Biofiltration Liquid Fertilizer

Abstract

Fifteen clones of poplars, 2 clones of willows, and yellow poplar were used to evaluate the effects of 5 treatments such as SCBLF (slurry composting and biofiltration liquid fertilizer), general slurry liquid fertilizer, chemical fertilizer, groundwater, and control (no treatment) on vitality, growth performance, and biomass production. Five cuttings for each tree species were planted in 3 replications. After planting cuttings, a coppice was induced by cutting off stems at 10cm above the ground. Data were collected for first growing season and trees were harvested at the end of October. Maximum mortality rate i.e. 96% was recorded in the cuttings treated with groundwater and minimum 92% with control (no treatment). In all tree species, sprouting of stump was not differ significantly among the treatments. Total nitrogen concentrations of leaves and stump sprouts were higher in the treatment of SCBLF than the control, 26.6% and 22.9%, respectively. Biomass production was highest in the stumps treated with chemical fertilizer,

Physiological changes and growth promotion induced in poplar seedlings by the plant growth-promoting rhizobacteria Bacillus subtilis JS

“…This is because land for plantations is limited, and wood crops need to be planted in large areas, such as reclaimed lands (Park et al 2009). However, some studies have shown that biomass production is limited in reclaimed lands (Yeo et al 2010, Kim et al 2011. If inorganic nutrients or substances, which can improve the growth of the rhizosphere system, are applied, the production of woody biomass can be increased.…”

Growth and Productivity Response of Hybrid Rice to Application of Animal Manures, Plant Residues and Phosphorus

“…Animal manure can serve as an important source for improving crop production and restoring essential nutrients depleted due to intensive cropping practices (Obi and Ebo, 1995 ; Sharpley and Smith, 1995 ; Bahman and James, 1999 ; Ano and Agwu, 2005 ; Materechera, 2010 ). Incorporation of crop residues also can improve soil fertility and increase crop yield (Singh et al, 2000 ; Prassad et al, 2002 ; Yadvinder et al, 2005 ; Bi et al, 2009 ; Olk et al, 2009 ; Kim et al, 2011 ; Huang et al, 2012 ). Nutrients from organic manures (animal manures and crop residues) are released more slowly and are stored for a longer time in the soil, thereby ensuring a long residual effect (Sharma et al, 1991 ; Ge et al, 2010 ; Hidayatullah et al, 2013 ; Amanullah and Khalid, 2016 ).…”

Evaluation of Bioenergy Potential and Relative Impact of Microclimate Conditions on Fuel Pellets Production and Carbon Storage of Short-Rotation Coppices (<em>Populus uramericana</em>) in Reclaimed Land, South Korea: Three-Year Monitoring

“…Total nitrogen (%) = (T -B) × f × N × 14 × 100 w -1 × 100 s -1 (11) Where T is standard solution of sulfuric acid (ml), B is standard solution of sulfuric acid for using …”
