Modeling ammonia emissions from manure in conventional, organic, and grazing dairy systems and practices to mitigate emissions

Journal of Dairy Science
: Almost 60% of all ammonia (NH3) emissions are from livestock manure. Understanding the sources and magnitude of NH3 emissions from manure systems is critical to implement mitigation strategies.

MANURE:

, 2016
Manure is a crucially important animal product in many mixed and sustainable agricultural production systems but, despite this, it is frequently overlooked by zooarchaeologists who instead tend to focus on more widely recognised contributions of domestic livestock to human subsistence.

Variation and spread of resistomes in swine manure, manure slurries, and long-term manure-fertilized soils

Frontiers in Microbiology
Background Application of swine manure to soils exacerbates environmental antimicrobial resistance (AMR). However, a comprehensive evaluation of anaerobic digestion’s (AD) mitigation potential against AMR and its influencing factors in swine manure-to-soil systems remains lacking.

Considering Manure and Carbon Sequestration

Science, 2000
In his Policy Forum “Carbon sequestration in soils” (25 June 1999, p. [2095][1]), William H. Schlesinger notes that manure application has been suggested as a possible mechanism for soil carbon sequestration ([1][2], [2][3]) and suggests that, although manuring has a number of ...

THE IMPACT OF PLANT PROTECTION AND FERTILIZATION ON CONTENT OF BIOACTIVE SUBSTANCES IN ORGANIC HOPS

Acta Scientiarum Polonorum: Hortorum Cultus, 2015
 Hop (Humulus lupulus) is one of the basic raw materials employed in brewing. All hops secondary metabolites exhibit pronounced bioactive effects. Therefore beer is the most important source of hop bioactive compounds in the human diet.

INFLUENCE OF FERTILIZATION AND HERBICIDES APPLICATION ON SOIL MICROFLORA AND ELEMENTS OF SUGAR BEET YIELD [PDF]

Poljoprivreda, 2004
Two-year sugar beet trials were set up on two localities: Đakovo (Stagnic Luvisol) and Osijek (Dystric Cambisol). The soils showed acid environment respond (pHKCL 4.9 – 5.4) and low humus contents (1.3 – 1.6%).

Influence of Ash Applied to Oat Crop (Avena sativa L.) Grown under Organic Fertilization with Manure

Scientific Papers Animal Science and Biotechnologies, 2023
The power plant ash is an inorganic residue with a variable chemical buildup according to the type of charcoal used and quality. Depositing, stabilizing and eventually reintegrating the ash in the natural circuit raises a series of problems due to its ...

Model Adaptation and Validation for Estimating Methane and Ammonia Emissions from Fattening Pig Houses: Effect of Manure Management System

Animals
This paper describes a model for the prediction of methane and ammonia emissions from fattening pig houses. This model was validated with continuous and discrete measurements using a reference method from two manure management systems (MMS): long storage
