in order to study the effect of solitary and combined application of two types of green manure, cow manure, barvar-2 phosphate fertilizer and conventional chemical fertilizer on some of the qualitative and quantitativeproperties of sugar beet, an experiment was conducted at the research farm of shahrekord university in 2013. the experimental design was randomized in a complete block design with...

Field experiments were conducted during the 2010 and 2011 cropping seasons to investigate the effect of farmyard manure and weeding regimes on the growth and yield of okra. The study was a factorial experiment laid out in split plot design, replicated three times. Farm yard manure was assigned as main plot treatments, while weeding regimes was assigned as sub plot treatments. Parameters measure...

soil is well known to support the transient or ongoing existence of kerathophilic fungi and potential sources of infection for humans and animals. fifty soil samples were collected from various areas of forests and farmyards at golestan province in the north part of iran to determine the prevalence of keratinophilic fungi and dominant species. a total of 357 fungal colonies including 13 genera ...

Ammonia (NH 3 ) emission inventories are required for modelling atmospheric NH 3 transport and estimating downwind deposition. A recent inventory for UK agriculture, estimating emission as 197 kt NH 3 }N yr~1, was constructed using 1993 statistical and census data for the UK. This paper describes the derivation of the UK-based emission factors used in the calculation of that emission for a rang...

The introduction of ecological sanitation (ECOSAN) toilets in villages near Bangalore hascreated opportunities for safer sanitation and recycling of human excreta, as fertilizers, in ruraland peri-urban areas. Field experiments were conducted at the University farm on French beansand Maize as the test crops in succession for 2 consecutive years in the same field. Differenttreatment combinations...

Ammonia (NH) emissions vary considerably among farms as influenced by climate and management. Because emission measurement is difficult and expensive, process-based models provide an alternative for estimating whole farm emissions. A model that simulates the processes of NH formation, speciation, aqueous-gas partitioning, and mass transfer was developed and incorporated in a whole farm simulati...

An on-farm study of 54 representative Wisconsin dairy farms was conducted to evaluate the influence of biophysical and socioeconomic factors on overall feed, fertilizer, and manure nutrient use. This report validates 1) how well data on cow diets, feed analyses, and milk production reflected established feed-milk-manure relationships; and 2) how well farmer-recorded data on manure land applicat...
