This study aimed to clarify the effects of biochar (BC made from Eucalyptus camaldulensis Dehnh.), and rice (Orysa sativa L.) straw (RS) amendments on soil productivity, carbon sequestration (Cseq) possibility for mitigating greenhouse gas (GHG) emissions. A field trial was conducted with 10 treatments: control, chemical fertilizer (CF) BC or RS each at four rates L (6.25 t/ha), ML (12.50 MH (18.75 t/ha) H (25.00 using a randomized complete block design replicates. The results showed that...
Abstract The sustainable management of leftover rice straw through biochar production to mitigate CH 4 emissions and enhance yield remains uncertain undefined. Therefore, we evaluated the effects using derived from left on fields after harvest greenhouse gas emissions, global warming potential (GWP), in paddy field. experiment included three treatments: chemical fertilizer (CF), (RS, 10 t ha −1 ) + CF, straw-derived (BC, 3 based amount product remaining pyrolysis) CF. Compared with BC CF...
Growing demands for crops have expanded agricultural production to sandy soils with low available phosphorus (P) content and high P mobility. Knowledge of speciation solubility in such is poorly understood. Here we investigated: i) the clay size fraction soils, ii) pH-dependent soil orthophosphate (PO4–P), iii) particle size-dependent P. The studied loamy sand were organic matter (2.6–7.9 g kg−1) deficient (1.5–8.5 mg kg−1), kaolinite (21%) was only mineral identified using X-ray diffraction...
Little is known about the carbonaceous greenhouse gases and soil microbial community linked to combination of biochar (BC) rice straw (RS) in paddy soils. The objectives this research were evaluate effects combining BC RS on (1) CH4 CO2 production from soil, (2) archaeal bacterial abundance, (3) grain yield. experiments consisted a pot trial an incubation trial, which had completely randomized design. included five treatments with three replications: (a) control (without BC, RS, chemical...
Abstract The fundamental ecosystem processes in soil are regulated by microbial communities, and community diversity is implicated environmental conditions. Humic acid (HA) improves quality fertility, stimulating the environment, but detailed effects remain poorly understood. We investigated of HA rates on bacterial diversity, particularly species richness composition rhizosphere corn ( Zea mays ). Inorganic fertilizer (T2), 0.5% (T3), 1.0% (T4), 1.5% (T5), 2.0% (T6) were applied soil....
Leaf litter plays a major role in carbon and nutrient cycling, as well fueling food webs. The chemical composition of leaf may directly indirectly influence decomposition rates by influencing biological reactions the accumulation soil organic content, respectively. This study aimed to assess impact rubber (Hevea brasiliensis (Willd. ex A. Juss.) Muell. Arg.) leaves on various properties different ages (4–5, 11–12, 22–23 year-old). Synchrotron-based Fourier transform infrared...
Soil phosphorus (P) plays an essential role in rubber tree plantations that are rapidly and extensively being established Southeast Asia. However, available information is quite limited on soil P fractions arbuscular mycorrhizal fungi (AMF) the tropical region. Herein, we investigated AMF community under natural forest at different ages of 5 years, 11 22 years coarse-textured soils from Thailand. The studied loamy sand were acidic (pH=5.0-5.7) with low concentrations (1.73-6.48 mg/kg). Data...
The objective of this experiment is to study the effect incorporated rice straw combined with chemical fertilizer (CF, basal 16-16-8, 40 kg/rai and top dressing urea (46%N), 60 kg/rai) on yield, soil bulk density, pH electrical conductivity. Six treatments 4 replications in RCBD were laid out. Rice seeds cv. Phatumtani1 sown. results showed that plots straw, 1-4 t/rai, gave yield ranged from 660 757 kg/rai, which higher than control (283.55 kg/rai). Bulk density combination CF 1.27-1.17...
The objective of this research was to study plant-microbe interactions in rhizospheric soil treated with different quality organic residues short-term incubation the and subsequent planting maize crop. treatments combinations were, 1) untreated (control; CT), 2) groundnut stover (GN) high nitrogen (N) but low lignin (L) polyphenol (PP), 3) tamarind leaf petiole litter (TM) medium N, L PP, 4) rice straw (RS) PP cellulose, 5) GN+TM, 6) GN+RS 7) TM+RS. Single mixed residue additions GN TM, both...
