Purpose Novel biomass-processing technologies have been recently used for conversion of organic wastes into valuable biofuels like bio-hydrogen. Agricultural wastes are available and renewable energy resources to supply energy demand of the future. The purpose of this study is to investigate the production of hydrogen-rich syngas from wheat straw, walnut shell, and almond shell. Methods […]
Background Application of different chemical fertilizers and manures is a major source of ammonia (NH3) emission. The rate and total amount of NH3 emission are related to different parameters such as climatic conditions, soil characteristics and kind of fertilizer. The current study has indicated the NH3 emission from bovine slurry, pig slurry and ammonium nitrate […]
Phosphorus (P) ore is an expensive and limited resource that will be depleted in a few decades if the current global consumption rate continues. Japan, one of the most developed countries in the world, relies completely on imported phosphate rock for P. Potassium (K) ore, which is equally important for continuous development, is also becoming […]
Background Vermicomposts (VC) improve plant growth and development beyond that normally observed from just soil nutrient transformation and availability. These increases in plant productivity have been attributed to improved soil structure and soil microbial populations that have higher levels of activity and greater production of biological metabolites, such as plant growth regulators. Although there have […]
Purpose Composting of harvested Salvinia natans weed of Loktak lake of Manipur, India can protect the precious lake from the unwanted growth of the weeds but there is a need to assess the total amount and bioavailable forms of heavy metals and minerals of the final compost before application as a soil conditioner. Methods Studies […]
Purpose In Saudi Arabia, owing to the abundant livestock, manures are a source of commercial humic amendments. Climate (hot weather plus scarcity of water sources) makes composting very difficult and compulsory to obtain these humic amendments without any previous composting step. A substantial fraction of manures, cellulosic in nature, are unextractable by alkaline solutions. Our […]
Purpose Spent mushroom compost (SMC) is a major solid waste product of the mushroom industry and is the material which remains at the end of a mushroom crop. Methods Different proportions of the SMC from Agaricus subrufescens cultivation were tested to produce seedlings and plants of tomato. A commercial substrate was used, both as a […]
Background Physical properties of substrates considered appropriate for plant growth at planting may change over time in containers as a result of several processes. Changes include air space reduction, shrinkage of the substrate, organic matter decomposition, and physical breakdown of particles. The objective of this research was to evaluate the physical properties of date palm […]
Purpose This study was performed to investigate the impact of various agricultural wastes as potting media on growth, yield, and quality flower production of Gerbera jamesonii L. cv. hybrid mix, and to estimate hazardous impact of chemical fertilizers. Method The effect of four agricultural substrates viz. farm yard manure, coconut coir dust, Lahore compost (local […]
Background A bibliometric analysis was used to assess the trend of solid waste-related publications produced by Iran and indexed in Scopus from 1982 to 2013. The study aims to analyze the distribution of languages, countries, institutes, journals, author keywords, authorship pattern and co-authorship relationships. Results The publication outputs showed an exponential trend (R2 = 0.98) […]
