The application of compost or fertilizer at rates that exceed crop nutrient requirements can result in phosphorus (P) and nitrogen (N) accumulation in soil. This study was conducted to determine the influence of soil P and N contents on the concentrations and total amounts of P and N transported in runoff. Composted beef cattle feedlot manure or inorganic fertilizer were added from 1992 to 1995...

plant secondary materials play an important role in health and human nutrition. according to the importance of coneflower in the production of secondary materials and also the effect of nutrient on the amount of secondary materials, a pot experiment was conducted with a completely randomized design six treatments and three replications in sari university of agricultural sciences and natural res...

To observe the comparative effects of poultry manure, household waste compost and fertilizers and their combinations on growth and yield of maize (Zea mays L.), this experiment was conducted in the crop field of the Department of Soil Science, University of Chittagong, Bangladesh during Rabi season in 2010-2011. There were ten treatments, one control and nine fertilizer combinations. In three s...

Compost is used mainly as an organic fertilizer, but it is also used as bedding material for cattle. Dairy cattle have been identified as a main reservoir of pathogenic Escherichia coli O157:H7. Further, E. coli is regarded as an environmental pathogen that causes bovine clinical mastitis. Hence, its growth in compost spread or compost bedding should be avoided. Physical and chemical conditions...

in order to study the effects of integrative applications of chemical fertilizers and biofertilizers on grain yield and oil of borago officinalis under water deficit stress, a field experiment was conducted at kermanshah, iran, in 2011. experiment was arranged as split plot under a randomized complete block design with 3 replications. water deficit stress with four levels was applied as the mai...

A capability to determine the availability of nitrogen in organic amendments is necessary to ensure that such materials will provide sufficient nitrogen to the growing crop and cause minimal environmental degradation. Greenhouse bioassays were used to evaluate N availability of organic by-products, including several employed in the field study of this research. Tall fescue was grown in greenhou...

Problem statement: MSW has traditionally been dealt with thorough the practice of land filling and incineration. However, deleterious environmental impacts have promoted municipalities in Canada to recycle non-putrescible wastes and compost the putrescible ones. This study aimed at evaluating the effect of MSW compost on the growth and production of three vegetable crops (potatoes, corn and squ...

This study sought to evaluate the efficacy of aerobic and anaerobic composting of inoculated banana peels, and assess the agronomic value of banana peel-based compost. Changes in the chemical composition under aerobic and anaerobic conditions were examined for four formulations of banana peel-based wastes over a period of 12 weeks. The formulations i.e. plain banana peel (B), and a mixture with...
