Compost maturity as expressed by phytotoxicity and Volatile organic acids
VOA in Composts Maturity is a qualitative trait of compost that may be expressed in a number of ways and is generally held to be relevant to plant performance. Volatile organic acids (VOA) have been cited to be responsible for phytotoxicity (plant growth suppression) when immature compost is used for growing plants (Manios et al., 1989). However, the production of VOA in compost has not been ...

Bi-On CPB minimises fungal infections in pineapples
Pineapples are susceptible to different diseases linked to air quality. The main problems include the growth of fungi on the crown, changes in the exterior colour from green to brown and sometimes considerable translucence inside the pineapple. As the pineapple is a non-climacteric fruit, ethylene does not accelerate its ripening, but it does speed up its senescence. Senescence causes a ...

Advances in phytoremediation
Phytoremediation has many proponents to treat widespread chemical contaminants in soil, water, and air. It is low-cost, eco-friendly, and doesn’t require complicated technology and infrastructure. As it is a new branch of science, it is necessary to understand the processes involved in the different methods of phytoremediation to advise decision-making for application of this technology. ...

Biodegradation of methane and halocarbons in simulated landfill biocover systems containing compost materials
The attenuation potential of methane (CH4) and of selected volatile organic compounds (VOCs) was compared in four types of compost materials using dynamic flow column experiments over a period of 255 d. Garden waste compost mixed with wood chips showed the highest steady-state CH4 oxidation rate (161 g m–2 d–1), followed by a commercial compost product Supermuld (110 g m–2 d–1). In the column ...

Innovative Uses of Compost Bioremediation and Pollution Prevention
Each year agricultural effluents, industrial residues, and industrial accidents contaminate surface waters, soils, air, streams, and reservoirs. A new compost technology, known as compost bioremediation, is currently being used to restore contaminated soils, manage stormwater, control odors, and degrade volatile organic compounds (VOCs). Compost bioremediation refers to the use of a biological ...

Wild Fires & Indoor Air Quality
Wildfires emit a cocktail of hazardous air pollutants, including fine particulate matter (PM2.5), volatile organic compounds (VOCs), and carbon monoxide. These pollutants not only deteriorate outdoor air quality but also infiltrate indoor environments. As a result, residents in wildfire-prone regions are at risk of breathing in polluted air, which can lead to various health issues. The Role of ...

Climacteric and non-climacteric fruits
Most fruits ripen due to the action of ethylene. Ethylene is the hormone known as "the ripening hormone". It is produced naturally in fruits causing the color, firmness, flavor and characteristic aromas of each fruit to change. However, once the fruit or vegetable has been collected, ethylene does not act in the same way in all cases. Depending on how ethylene intervenes on fruits, they are ...

Methyl bromide as a fumigant for International transports
Methyl bromide is a is an odourless, colourlessgas most often used as a fumigant. About 70% of methylbromide produced in the United States goes into pesticidal formulations. It has been used to fumigate agricultural commodities, grain elevators, mills, ships, clothes, furniture greenhouses and delicate works of art. Non-pesticidal uses include degreasing wool and extracting oils from nuts, seeds ...

South Kern Compost manufacturing facility case study
The Challenge Seated approximately 30 miles southwest of Bakersfield, California, the South Kern Compost Manufacturing Facility (SKCMF) was commissioned in 2006 to alleviate concerns about long-term viability of land application of Class B biosolids in Southern California, and address air quality issues of previous traditional composting processes. The Solution As the country’s most ...

Hexane Detection in Oilseed Operations - Case Study
Optical Gas Imaging (OGI) is a proven technology for locating Hexane and other Volatile Organic Compound (VOC) leaks in oilseed operations. OGI inspections can improve plant safety during routine operations, and reduce revenue lost to downtime during major overhauls. ROI payback in less than one year has been reported by major oilseed crush operations. A new Hexane and VOC leak detection ...

Detecting plant root diseases & pests
Soil-borne pests and diseases are harder to detect than those on the aerial parts of a plant. Visible symptoms in leaves and stem appear only in the final stages of the attacks. If plants are treated at this point, it may be difficult to avoid plant injury, as plants could already have been severely impacted. Early detection and identification are key to prevent crop loss. There are, however, ...

Uses of winery and distillery effluents in agriculture: characterisation of nutrient and hazardous components
ABSTRACTTwenty-one samples of winery and distillery effluents were collected from different Spanish winery and distillery industries. Electrical conductivity, pH, redox potential, density, organic charge (chemical oxygen demand, biological oxygen demand, total, volatile and suspended solids, oxidisable organic C and polyphenols) and contents of plant nutrients and heavy metals were analysed. The ...

Composting in the Subarctic – Moisture
Regulating Compost Moisture during Hot Composting Hot composting is most effective at decomposing organic waste when moisture levels are approximately 50%. A compost with excessive moisture will cause Low temperatures that are below 40°C (104°F); smells foul; and/or brown liquid to be visible or easily freed when squeezing compost. Excessive moisture while composting does not ...
