peanut shelles as a waste of cultivated peanuts are produced in a considerable amount in guilan province, iran, that its compost can be used as an available resource in replacement of peat as growth medium of ornamental plants.this experiment was carried out to determine the possibility using of peanut shells compost as an appropriate medium of dracaena. the control treatment was a medium of pe...

The present research was conducted to mitigate the environmental contamination and with the aim of evaluating the possible impacts of the application of sugarcane bagasse sewage sludge-based compost (BSC), vermicompost, and fish compost on different aspects of physiology, growth, and development of Lilliumlongiflorum var Ceb-Dazzle. The bulbs were planted in four different prepared soil mixture...

We studied the effects of applying different composts (urban organic waste, green waste, manure and sewage sludge), mineral fertilizer and compost plus mineral fertilizer on chemical, biological and soil microbiological parameters over a 12-year period. The organic C and total N levels in soils were increased by all compost and compost + N treatments. Microbial biomass C was significantly (P £ ...

Earthworms (Eisenia foetida) produce humic substances that can influence plant growth by mechanisms that are not yet clear. In this work, we investigated the effects of humic acids (HAs) isolated from cattle manure earthworm compost on the earliest stages of lateral root development and on the plasma membrane H(+)-ATPase activity. These HAs enhance the root growth of maize (Zea mays) seedlings ...

Studies were carried out to Screen the bacterial compost from spoiled vegetables and fruits and their physiochemical characterization. Samples were collected from local market and super markets in and around Madurai, Tamil nadu, India. Collected samples were processed by using Total Microbial Count, Standard Plate Count and Coli form count. Bacillus spp. and Pseudomonas spp. were dominantly fou...

Environmental impact assessment is an important tool in assuring that development projects will go according to environmental limits. The need for a systematic method of evaluating the environmental effects of a project or a plan has been recognized for several decades. In this study application of improved mathematical matrices for environmental impact assessment was suggested. For this, quali...

The present study aims to residual effects of composts (plant residues, animal residues and mixed) with and without inorganic fertilizers on spinach (spinicia oleracea L.) plants and soils. The obtained results showed that the finished compost of plant residues was high in germination index (GI) and low in C/N ratio compared with the other composts. The study demonstrated that the spinach yield...
