“…Compost CO 2 respiration rates were measured using an infrared gas analyzer system equipped with a S8-0050 CO 2 infrared sensor (SenseAir Ab, Delsbo, Sweden) as described previously [ 20 ] with modifications. Briefly, 30 g of individual compost sample and a CO 2 sensor were placed and sealed in a 300 mL chamber, kept at room temperature, and monitored for CO 2 concentrations every 2 sec.…”

Regular usage of NaOH/NaClO disinfectants results in high sodium salt and alkalinity of poultry manure. This study compared three amendments: vegetable waste (V), food waste (F) and mature compost (C) for their ability to improve the composting of NaOH/NaClO-contaminated poultry manure. C compost resulted in the highest compost temperatures (p<0.001) and greatest reduction in OM, TC, TN and NH4-N (p<0.05). C and V composts were more efficient at lowering extractable-Na (ext-Na) and electrical conductivity (EC) than F (p<0.05). Maturity was primarily indicated by NH4-N, EC and ext-Na. Bacterial dynamics was profoundly influenced by NH4-N, EC and TC, with the decrease leading to discriminate genera shift from Sinibacillus and Thiopseudomonas to Brevbacterium, Brachybacterium, and Microbacterium. These findings suggest that mature compost was more desirable amendment than vegetable and food waste in the composting of NaOH/NaClO-contaminated poultry manure, and the decrease of ext-Na indicated compost maturity but did not influence bacterial dynamics.

“…Pambayun et al (2015) also found that the addition of Ridwan P. Putra, Hydrodynamics of Fluid Flow in Fixed-beds Composed of Sand Particles and Hollow Fiber Membrane Pipes compost to the soil will increase the porosity of the bed from 0.60, for the untreated soil, to 0.75, for the pure compost medium. The enhanced porosity in soil may provide more space in the soil, resulting in the improved CO2 exchange from the soil to the atmosphere, produced from the respiration of plant roots and the degradation of organic matters (Yu, 2015). In another study, Yan et al (2016) investigated the relationship between microbial respiration to investigate organic carbon degradation in soil, CO2 production and emission, as well as their other effects on climate change.…”

ABSTRAK Kompos artifisial yang dibuat dari bahan polimer baru-baru ini menarik perhatian peneliti sebagai pupuk yang tahan lama dan dapat meningkatkan produktivitas tanaman tanpa menimbulkan dampak yang besar pada lingkungan. Dalam penelitian ini, pipa membran hollow fiber (HFMP) yang terbuat dari bahan polipropilen dan pasir kuarsa, masing-masing digunakan sebagai model kompos artifisial dan partikel tanah. Hidrodinamika unggun yang terdiri dari HFMP dan pasir kuarsa diteliti dengan menggunakan metode falling-head. Hasil percobaan menunjukkan bahwa unggun yang ditambahkan HFMP mengalami peningkatan porositas unggun. Unggun dengan fraksi HFMP yang lebih tinggi menunjukkan kemampuan menahan air yang lebih rendah, yang mengindikasikan kemampuan yang buruk dari bahan polipropilen dalam menahan molekul air. Sebaliknya, permeabilitas yang lebih tinggi pada unggun yang ditambahkan HFMP menunjukkan aliran cairan yang lebih baik. Studi ini mengungkap potensi kompos artifisial yang dapat diterapkan dalam teknologi pertanian berkelanjutan. Kata kunci: Hidrodinamika, kapasitas menahan air, porositas, permeabilitas, kompos buatan ABSTRACT Artificial compost fabricated from polymer materials has recently attracted considerable interest as a highly durable fertilizer that could enhance plant productivity without harming the environment. In this study, polypropylene hollow fiber membrane pipes (HFMP) and quartz sand particles were employed as models of the artificial compost and soil particles, respectively. The hydrodynamics of various volumetric ratios of beds composed of the HFMP and the quartz sand were investigated using a falling-head technique. The results show that the bed supplemented with the HFMP demonstrated enhanced bed porosity. The bed with a higher HFMP fraction exhibited slightly less water-holding capacity, which suggests the poor ability of the polypropylene material to retain water molecules. On the contrary, the higher permeability of the bed amended with the HFMP indicates improved water flow. This study unfolds the potential of artificial compost that can be implemented in sustainable agricultural technology. Keywords: Hydrodynamics, water-holding capacity, porosity, permeability, artificial compost

“…However, soil respiration is controlled by soil temperature, soil moisture, soil aeration (Cook and Orchard 2008), soil nitrogen content (Song et al 2021), differences in canopy structure, plant biomass, and associated litter quality (Xu et al 2015), which in uences soil physico-chemical properties (Aponte et al 2012) and soil microbial community structure, and eventually result in soil autotrophic and heterotrophic respiration (Xu et al 2015). In cotton, soil respiration was greatly in uenced by soil water content and external irrigation, which directly affects the root respiration activity and soil CO 2 production and exchange (Yu et al 2015). Previously, Bhattarai et al (2006) reported low oxygen and lesser respiration can lead to lesser cotton yields on a heavy clay soil.…”

Purpose No attempts were made to analyze the diversity in soil and plant biology of wild cotton species (WCS) and cultivated cotton species (CCS), so far. Our study aimed to understand the differences in soil biological, plant biochemistry, and defense enzyme activities among the ten WCS and four CCS. Methods We studied the differences in soil biology, plant biochemistry, and defense enzyme activities among the ten WCS (Gossypium anomalum, G. aridum, G. australe, G. barbosanum, G. capitis-virides, G. davidsonii, G. raimondii, G. somalense, G. stocksii, G. thurberi) and four CCS (G. arboreum, G. herbaceum, G. hirsutum, and G. barbadense). Results CCS had 11%, 2%, and 10% higher soil respiration rate, microbial biomass carbon, and microbial metabolic quotient, respectively, compared to WCS. While, WCS had 45%, 15%, and 5% higher glomalin, soil polysaccharide, proteins, respectively, compared to CCS. WCS had 45%, 13%, 8%, and 13% higher acid and alkaline phosphatase, β-glucosidase, and soil dehydrogenase activities, respectively, compared to CCS. WCS had higher carbohydrates in the shoot (40%) and root (27%), while, CCS recorded higher proteins in the shoot (13%) and root (13%). WCS had significantly higher polyphenol oxidase (4% and 15%), peroxidase (30% and 31%), and catalase (36% and 31%) activities in shoots and root tissues, respectively, compared with CCS, while, WCS had higher phenol concentrations (4%) than CCS. Conclusion Our study suggests that the difference in soil biological, plant biochemistry, and defense enzyme activities among the WCS and CCS can be attributed to the inherent genetic makeup, which influences consequent plant and soil attributes.
