ABSTRACT Compost tea is being used increasingly in agricultural production to control plant diseases. However, there has been limited investigation relating disease control efficacy to various compost tea production methods, particularly compost tea produced with active aeration and additives to increase microbial population densities in compost tea. Aerated compost tea (ACT) and nonaerated com...

This study was conducted to determine the effect of compost and compost tea on growth and physiological parameters of Lepidium sativum L. 30-day-old Cress plants treated with compost and compost tea were harvested and different growth and physiological parameters were measured. Compost tea application increased RGR, SLA, ULR and RLAGR. The contents of Chlorophyll a and Chlorophyll b in the plan...

Andrographis paniculata (Burm.f.) Nees is a medicinal herb in the family Acanthaceae. The leaves of the mature plant contain abundant diterpinoids of medicinal properties.The objectives of the present study were to investigate the impacts of compost tea rates on photosynthesis parameters and antioxidant reactions of A. paniculata. The plant was propagated using seed and planting in a polybag. A...

This study investigated the chemical characteristics and microbial population during incubation of four kinds of aerated compost teas based on oriental medicinal herbs compost, vermicompost, rice straw compost, and mixtures of three composts (MOVR). It aimed to determine the effects of the aerated compost tea (ACT) based on MOVR on the growth promotion of red leaf lettuce, soybean and sweet cor...

A sequential chemical fractionation was applied to a compost, with its dissolved organic matter (DOM) extracted in water and separated in hydrophilic (HiDOM) and hydrophobic (HoDOM) components and a water extract, following oxidation of compost suspension with an oxygen flux (TEA). The components sequentially isolated by mild extractions and hydrolyses as structurally unbound (SU), weakly bound...

Compost tea describes a procedure where compost is mixed with water. The mixture may be left to stand with minimal disturbance, also called “compost extract” or “steepage”, or actively supplied with oxygen by an aquarium pump to stimulate population growth of aerobic microbes. This project examined actively aerated compost tea. Over a 3-year period, 25 experiments were conducted where a standar...

Compost, poultry litter, IPM Lab Biopesticide and BAU-Biofungicide, either alone or in combinations, were assessed for their effect in controlling early blight disease, and on growth and yield parameters of tomato. The lowest early blight incidence and severity were recorded in T13 (compost tea + poultry litter extract + BAU-Bio-fungicide) followed by T12 (compost tea + poultry litter extract +...

In the present study, packaging of a greenhouse-grown tomato on the culture medium containing 0, 25, 50, 75 and 100% compost tea under modified atmosphere: MA (88%N2 + 8%CO2 + 4%O2) in polyethylene and nanosilicon-polyethylene bags was studied at 5°C for 30 days. Several quality parameters such as moisture content, pH, total soluble solids (TSS), titratable acidity (TA), Vitamin C content, text...
