Paecilomyces variotii: A Fungus Capable of Removing Ammonia Nitrogen and Inhibiting Ammonia Emission from Manure
Ammonia (NH3) emissions from animal manure are a significant environmental and public concern. Despite the numerous studies regarding NH3 emissions from manure, few of them have considered microbial nitrification approaches, especially fungal nitrification. In this study, a filamentous fungus was isolated from chicken manure and was used for nitrification. The species was Paecilomyces variotii ...
متن کاملGÉRARD-MARCHANT ET AL.: P LOSS FROM MANURE DURING RAINFALL Simple Models for Phosphorus Loss from Manure during Rainfall
Mechanistic, predictive equations for phosphorus (P) transport in runoff from manure-applied fields constitute a critical knowledge gap for developing nonpoint-source pollution models. We derived two simple equations to describe the P release from animal manure during a rainfall event—one based on first-order P desorption kinetics and one based on second-order kinetics. The manure characteristi...

متن کاملNitrogen and Phosphorous Loss as Affected by Plough Direction in Rainfed Wheat Land of a Semi- Arid Region
Sloping farmlands are the major sources of soil, water and nutrient losses in arid and semi-arid regions. Information about the impacts of different tillage practices on soil erosion, nutrient loss and crop nutrient uptake on the sloping farmland of semi- arid soil is, however, limited. This study was carried out to investigate the effects of tillage direction on soil, water, nitrogen and phosp...
متن کاملReduction of the Livestock Ammonia Emission under the Changing Temperature during the Initial Manure Nitrogen Biomineralization
Experimental data were applied for the modelling optimal cowshed temperature environment in laboratory test bench by a mass-flow method. The principal factor affecting exponent growth of ammonia emission was increasing air and manure surface temperature. With the manure temperature increasing from 4°C to 30°C, growth in the ammonia emission grew fourfold, that is, from 102 to 430 mg m(-2)h(-1)....
