Manure or compost application based on N needs of corn (Lea mays L.) may result in soil accumulation of P, other ions, and salt because the manure or compost N/P ratio is usually smaller than the corn N/P uptake ratio. This study was conducted from 1992 to 1996 to evaluate effects of Pand N-based manure and compost application on corn yield, N and P uptake, soil P level, and weed biomass. Compo...

In a country like Iran, where soil organic matter is less than 1% and in most cases even less than 0.5 %, Municipal solid waste (MSW) is a permanent and inexpensive source of organic matter. Various experiments have indicated that applications of compost improve plant health, yield and nutritional quality. However, the quality of the compost determines the growth and the development of plants. ...

Abstract. Preliminary research has shown that sodium pentobarbital (SP), a euthanasia drug, can persist up to 180 days in equine mortality compost piles. This study attempts to expand upon past research by quantifying SP residues in equine mortality compost piles over a longer duration using innovative sampling schemes. Six, 3.7 m plots were used to construct separate compost bins with 3 bins s...

Little information is available on the effects of applying compost tea to species in dry regions. Compost from agricultural waste can promote drought resistance in plants and increase their growth by improving soil structure and providing nutrients and enhancing the capacity of the soil to store moisture. In order to examine these effects, compost tea was tested on two species growing in dry re...

This paper describes how compost, a by-product generated by solid waste treatment plants, can be usefully applied to road embankments to prevent erosion. Our study analyzed this process in terms of the following variables: (1) location and orientation; (2) embankment slope; (3) soil and compost characteristics; (4) compost dosage; (5) vegetation species; (6) plot dimensions; and (7) planting me...

Composts are known for their suppressive properties toward many different seed- and root-infecting pathogens and diseases. Although disease and pathogen suppression induced by composts is believed to be mediated by microbial activities, the nature of the microbial species and processes responsible for suppressiveness remain unknown. We demonstrated previously that seed-colonizing microbial cons...

The goal of this study was to evaluate the microbial die-off in a latrine waste composting system in Port-au-Prince, Haiti. Temperature data and samples were collected from compost aged 0-12+ months. Samples collected from compost bin centers and corners at two depths were assessed for moisture content, E. coli concentration, and Ascaris spp. viability. Center temperatures in compost bins were ...

Introduction Compost is a soil amendment produced through the metabolism of an organic substrate—a surface on which organisms grow—by aerobic (oxygen-requiring) microbes under controlled conditions. Composting is an ancient agricultural technology going back to biblical times that still has important applications in modern agriculture. Recent years have seen a resurgence of interest in compost ...
