Comparing conventional and improved organic vegetable rotations, yields and nitrogen husbandry [PDF]

open access: yes, 2010
During 2005 to 2009 three approaches to organic vegetable rotations were compared to a conventional rotation in an interdisciplinary project. The organic rotations differed in their reliance on animal manure vs.

Production of biogas using biomass [PDF]

open access: yes, 2020
There is a great deal of environment pressure in many parts of the world to as certain how livestock waste can best be handled. Livestock manure, like cow dung, food waste, kitchen waste in the absence of appropriate disposal methods can cause adverse ...

Nitrogen Turnover on Organic and Conventional Mixed Farms [PDF]

open access: yes, 1995
Separate focus on crop fertilization or feeding practices inadequately describes nitrogen (N) loss from mixed dairy farms because of (1) interaction between animal and crop production and between the production system and the manager, and (2 ...

Mitigating VFA accumulation in hydrogen‐assisted anaerobic digestion through MEC integration

open access: yesJournal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND Biological hydrogenotrophic methanization is a promising method to improve biogas quality in anaerobic digestion systems. However, hydrogen‐assisted anaerobic digesters (AD‐H2) are prone to volatile fatty acid (VFA) accumulation and process instability.

Repeated use of green-manure catch crops in organic cereal production - grain yields and nitrogen supply [PDF]

open access: yes, 2011
By restricted access to manure, nitrogen (N) supply in organic agriculture relies on biological N-fixation. This study compares grain yields after one full-season green manure (FSGM) to yields with repeated use of a green-manure catch crop.

Cultivating biodiversity: When conservation in agricultural landscapes embodies farmers' values

open access: yesPeople and Nature, EarlyView.
Abstract Efforts to conserve biodiversity in agricultural landscapes across Europe remain insufficient, as biodiversity further declines. This is sometimes ascribed to conservation policy failing to address the meanings and values that farmers attribute to the social and ecological contexts shaping their decisions influencing biodiversity.

THE INVESTIGATION OF CROP WEEDINESS IN THE CROP ROTATION OF ORGANIC FARMING SYSTEM [PDF]

open access: yes, 2008
Field experiments were conducted during the period of 2004 – 2006 at the Research and Study Farm „Vecauce”. The aim of the investigation was to establish the weediness’ dynamics of crops in a six-field crop rotation of an organic farming system.

Effect of organic manures and liquid organic manures on growth, yield and economics of aerobic rice cultivation

open access: yesINTERNATIONAL JOURNAL OF AGRICULTURAL SCIENCES, 2015
Field experiment was conducted to know the response of organic manures on growth, yield, quality and economics of aerobic rice during Kharif 2011 at MARS, Dharwad. Results indicated that among organic treatments combined application of EC(1/3) + VC(1/3) + GLM(1/3) equivalent to RDF + FYM in combination with foliar application of jeevamrut @ 500 l ha ?
