To investigate the effects of organic fertilizers and irrigation frequencies on yield and quality of cherry tomato an experiment was conducted using six fertilizer doses including control (no fertilizer), NPK fertilizer (urea at 300 kg, TSP 200 kg and MoP 250 kg), cow-dung at 5 t ha-1, cow-dung at 10 t ha-1, poultry manure at 5 t ha-1 and poultry manure at 10 t ha-1 with two levels of irrigatio...

A laboratory air emission evaluation system consisting of eight emission vessels (19 L each) has been developed and used to investigate the effects of bio/chemical agents or feed additives on ammonia and odor emissions from poultry manure. A novel approach was used to evaluate volatile organic compounds (VOCs) and odor emissions, featuring air sampling with carboxen/PDMS 85 micrometer SPME fibe...

Effect of composting on the extractability of plant nutrients in organic wastes is essential for their recycling in sustainable soil fertility management. Therefore, an experiment was carried out to determine the concentrations of total C, total N, extractable P, K, Na and B in five types of fresh and composted manures (namely buffalo, camel, cow, goat and poultry). Laboratory results showed th...

The epidemiology and control of avian influenza (AI) are complex. The virus is transported in nature by the activities of wild birds and in commercial poultry by the activities of people. In general, all the outbreaks of AI in the United States of America (U.S.A.) have involved AI virus spread by the movement of poultry and manure and objects contaminated by poultry and manure, butthe specific ...

the purpose in this research was to study the effects of vermicompost and poultry manure on yield and yield components of the medicinal plant coriander (coriandrum sativum l.) in the shahr-e- ghods region. a factorial experiment using the randomized complete block design with three replications was conducted in the islamic azad university of shahr-e- ghods. the first factor was three levels of ...

Concern over the enrichment of agricultural runoff with phosphorus (P) from land applied livestock manures has prompted the development of manure amendments that minimize P solubility. In this study, we amended poultry, dairy, and swine manures with two rare earth chlorides, lanthanum chloride (LaCl(3).7H(2)O) and ytterbium chloride (YbCl(3).6H(2)O), to evaluate their effects on P solubility in...

Immense quantity of waste is generated in association with poultry meat egg and crop production. The potential risks due to disposal of these wastes are magnified as a result of dense refinement of poultry production and the decreasing amount of land available for waste disposal. The study aims at studying the microbiological biodiversity of poultry waste and paddy straw based co-composting sys...

During the past five years we have developed three emission calorimeters (EC) that can be used to evaluate mass generation and utilization of gasses. We have tested various treatments that significantly reduced ammonia generation by laying hen manure (Harrison and Koelkebeck, 2002; 2003).

A leaching experiment was conducted on three level of total N soils transplanted with lettuce in packed soil columns. Nitrate content in the surface soil layer increased to 52.6, 92.8 and 92.1 mg kg-1 when 30 t ha-1 poultry manure was used alone in the low, medium and high level of total N soils. Measured leachate data showed that more nitrate was leached in the chemical fertilized soils in the...
