The application of organic amendments can be an appropriate solution to reclaim and improve physical propertiesof saline-sodic soils. In this research, an experiment was performed under greenhouse conditions to study the effect ofamendments to the physical properties of loamy saline-sodic soil. The five treatments were control (withoutamendment), municipal solid waste compost (MC), vermicompost...
The potential of Jiroft region has resulted in progressive development of greenhouse culture. In sustainable agricultural systems, organic manures have special role in increasing yield and soil fertility. To investigate the quantitative and qualitative responses of greenhouse cucumber to sources and levels of organic manures and their effect on some soil properties in Jiroft region, a factorial...
In order to investigate the cumulative effect of three-year application of municipal solid waste compost (C) and the compost accompanied with chemical fertilizer (CF) on the concentrations of some heavy metals in various organs of rice plant, a field experiment with completely randomized design in three replications was performed in 2009. Treatments were as follows: Control (without C and CF), ...
Due to high production of organic residues such as sewage sludge and compost, land application is probably the best way to prevent accumulated residues in the environment. However, the risk involved in the land application of organic residues should be evaluated prior to the assessment of their economic and fertilizer values. The objective of this study was to evaluate the effect of organic res...
in order toa desirable growth, plants need fertile soil which has the availability of nutrient elements in it. sometimes, in spite of having access to the nutrient elements, decrease yield, due to undesirable physical situation. stock (matthiolaincana cv. column crimson) is one of the potting flower that its growth medium traditionally including hawar soil, basin sediment and untreated waste mu...
Home composting systems (HC) are known to facilitate municipal solid waste management, but little is known about their environmental impact including their greenhouse gas emissions (GGE). The present research focused on selecting HC configuration producing the least CH(4) and N(2)O. Thus, 4 HC types were used to compost food and yard waste for 150 days and monitored for CO(2), CH(4) and N(2)O a...
are enhanced. Sugarcane germination can also be promoted by increasing soil Ca (Mohandas et al., 1983). Louisiana sugarcane (Saccharum spp.) is produced mainly on For some crops, gypsum is effective in reducing the heavy-textured soils that offer less than ideal conditions for growth and function of the root system. Cultural practices that improve the incidence of soil-borne diseases (Kao and K...
In this review we discuss the transformation of organic matter during municipal solid waste (MSW) composting and the suitability of chemical and biochemical parameters in defining the stability and maturity of the end product. The dynamics of chemical and biochemical parameters, such as several hydrolase activities and water-soluble fractions (i.e. water soluble carbon, water soluble nitrogen, ...
INTRODUCTION An environmental impact assessment (EIA) before embarking on any project is a useful tool to reduce the potential effects of each project, including landfill, if possible. The main objective of this study was to assess the environmental impact of the current municipal solid waste disposal site of Gonabad by using the Iranian Leopold matrix method. METHODS This cross-sectional stu...
Fermentable components of municipal solid wastes (MSW) such as fruit and vegetable wastes (FVW), leaf litter, paddy straw, cane bagasse, cane trash and paper are generated in large quantities at various pockets of the city. These form potential feedstocks for decentralized biogas plants to be operated in the vicinity. We characterized the fermentation potential of six of the above MSW fractions...
