Purpose: Poor management of chicken litter by the poultry industry has caused many environmental issues. Biochar’s unique characteristics make poultry litter-to-biochar conversion an intriguing management option thus, could be utilized as an organic fertilizer for plant nutrients. In this research, poultry litter was converted into biochar, which offers a range of possible applications, including analyzing […]
Purpose Agricultural crop residues (ACR) and agro-industrial waste (AIW) are abundant in Indonesia and primarily used as substitutes for cattle feed or to be naturally decomposed in the nearby environment. This review attempts to examine the potential valorisation of ACR and AIW into biosorbent. This paper also provides the challenges and opportunities in applying wastewater […]
Purpose: The limitation of the use of some agricultural wastes is their C/N ratio. This study was aimed at integrating cocoa pod husk, moringa leaves, and poultry droppings in composted form for enriched soil amendments for vegetable production. Method: Three compost types: cocoa pod husk, moringa leaf, and poultry droppings were composted for 60 days […]
Purpose: Exploring alternatives to mitigate soil degradation has been gaining importance in recent years. Biochar promises to improve properties such as soil fertility and soil conditioning. This research involved an experiment with different levels of biochar in associating it with some chemical properties and the wood yield of A. mangium. Method: We used a design […]
Purpose The consecutive amendment of composted tannery sludge (CTS) could promote changes in the status of soil microorganisms. Thus, this study evaluated the changes on microbial C and enzyme activities in soil after 9 years of CTS amendment. Methods CTS was amended from 2009 to 2018 at five rates: 0, 2.5, 5, 10, and 20 […]
Purpose: The study presents how to develop and optimize a spectral measurement methodology for monitoring the composting process of broiler and hen manure using zeolite. Models were set up to determine the pH, electrical conductivity (EC, dS m−1), and moisture content (MC, w/w%) from reflectance data using spectral indices to establish a rapid, noninvasive, non-destructive […]
Purpose Biochar is a carbon-rich coproduct resulting from pyrolyzing biomass. Positive effects on productivity, soil stability, carbon sequestration, soil fertility have been validated by several studies. The aim of the present study is to compare the effect of different rates of biochar “BC TD” (produced from the pyrolysis of seeds of date ‘D’ and “Tomato […]
Purpose: One of the primary wastes of the sugar industry that has the potential to be converted into fertilizer is filter cake. Organomineral fertilizer is proposed as a promising approach. Therefore, this research evaluated the efficiency of various filter cake-based organomineral formulations for sweet maize growth under different fertilization rates. Method: The treatments comprised of […]
Purpose The main objective of the present study was to evaluate the effects of compost formulation made from agricultural by-products and thermal treatment of fresh mushrooms on the postharvest quality parameters. Methods Quail manure was evaluated as an alternative ingredient to the broadly used chicken manure for compost preparation. In addition, the treatment of fresh […]
Purpose Rice is a staple food in Nigeria, but its cultivation faces constraints of soil acidity, low soil fertility and rainfall variability. Research has shown that biochar has the potential to alleviate the effects of these conditions, but responses vary depending on soil and climate factors. Therefore, this study was conducted to evaluate the effects […]
