Composting animal manure has the potential to reduce emissions of nitrous oxide (N2O) and methane (CH4) from agriculture. Agriculture has been recognized as a major contributor of greenhouse gases, releasing an estimated 81% and 70% of the anthropogenic emissions of nitrous oxide (N2O) and methane (CH4), respectively. A significant amount of methane is emitted during the storage of liquid manur...
A pot experiment was conducted during Kharif season, 2005 to ascertain the response of different organic sources viz., wheat straw, farm yard manure (FYM), vermicompost and poultry manure to rice (Oryza sativa) and also to monitor the effect of manuring on soil carbon pools. Application of poultry manure and vermicompost alongwith chemical fertilizers for supply of nitrogen, phosphorus and pota...
Study of phosphorus reactions over time and the role of organic matter in the calcareous soils are important for the development of P fertilizer and manure management practices. The objective of this study was to determine the effect of applied manure on P availability and its chemical forms in the soil, over time. Eight samples were collected from semi-arid calcareous soils of Mashhad plain. T...
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 ...

Large amounts of fertilizers and pesticides applied annually to agricultural soils improve the physical and chemical properties of soil but, when they are applied without control they can cause serious environmental problems. The farms of Tizayuca in Hidalgo State produce about 30000 tons of manure per day, which are applied indiscriminately in the same region for agricultural use. The aim of t...
Manure is applied to cropland areas with varying surface cover to meet single‐year or multiple‐year crop nutrient requirements. The objectives of this field study were to: (1) examine runoff water quality characteristics following land application of manure to sites with and without wheat residue, (2) compare the water quality impacts of land application of manure to meet 0‐, 1‐, 2‐, 4‐, and 8‐...
Despite the fact that erosion undermines productivity in the Ethiopian highlands, adoption of fertility enhancing techniques remained very minimal. The objectives of this study is to examine factors affecting adoption of fertilize and manure use and their interrelationships using plot and household level data collected from 211 farm households. A two-stage probit model results revealed a negati...
Managing manure in reduced tillage and forage systems presents challenges, as incorporation by tillage is not compatible. Surface-applied manure that is not quickly incorporated into soil provides inefficient delivery of manure nutrients to crops due to environmental losses through ammonia (NH3) volatilization and nutrient losses in runoff, and serves as a major source of nuisance odors. An arr...
in order to study the effect of different resources of farmyard manure, compost and biofertilizers on grain yield and quality of canola (talaieh cultivar), an experiment was conducted at kurdistan region in 2008 and 2009 growing season. experimental units were arranged in split-split plots design based on randomized complete blocks with three replications. main plots consisted of two locations ...
