A study was conducted to investigate the levels of plant nutrients, heavy metals, parasites and fecal coliform bacteria in Bangkok-produced sewage sludge and finished compost products for potential agricultural application, as well as to compare the quality of compost under different composting conditions. The results indicated that digested sewage sludge had high fertilizing values for organic...

This study was undertaken to evaluate natural mulches for weed control in organic onion (Allium cepa) production where current practices rely on hand-weeding or plastic mulch. Three experiments were conducted over 2 years, with two experiments conducted on-farm in different years and one experiment conducted on-station. Treatments consisted of hand-weeding or mulches of wheat (Triticum aestivum...

The phytotoxic and antimicrobial properties of olive mill wastes have been widely investigated and demonstrated over the past decade. However, their potential utilization as biodegradable pesticides against plant pathogens is still poorly understood. In this study, a series of laboratory bioassays was designed to test the inhibitory effects of sterile water extracts of two-phase olive mill wast...

Transitioning farmland to certified organic vegetable production can take many paths, each varying in their costs and benefits. Here, the effects of four organic transition strategies (i.e., tilled fallowing, mixed-species hay, low-intensity vegetables, and intensive vegetable production under high tunnels), each with and without annual compost applications for 3 years prior to assessment, were...

Geobacillus sp. strain WSUCF1 is a thermophilic spore-forming member of the phylum Firmicutes, isolated from a soil sample collected from the compost facility. We report the draft genome sequence of this isolate with an estimated genome size of 3.4 Mb. The genome sequence of this isolate revealed several genes encoding glycoside hydrolases, making it a potential candidate for plant biomass degr...

in recent years the use of organic and biological modifier as an environmental friendly replacement for chemical fertilizers has been used more. in order to study the effect of different levels of biological fertilizers and mushroom compost on flower yield and characteristics of saffron corms (crocus sativus l.), a split plot experiment based on rcbd design with three replications was conducted...
