recently organic agriculture as a most popular alternative production system has increasingly been considered by scientists, people and policymakers and governments in the world, and many research programs are directed to this sustainable production system. in organic agriculture it is hardly recommended to integrate plant with animal husbandry in agroecosystem. various animal products such as ...
Organic and Low-Input Dairy Farming: Avenues to Enhance Sustainability and Competitiveness in the EU
We have used molecular biological methods to study the distribution of microbial small-subunit rRNAs (SSU rRNAs), in relation to chemical profiles, in offshore Lake Michigan sediments. The sampling site is at a depth of 100 m, with temperatures of 2 to 4 degrees C year-round. RNA extracted from sediment was probed with radiolabeled oligonucleotides targeting bacterial, archaeal, and eukaryotic ...
The aim of this paper is to design a single input PI fuzzy controller for a nonlinear and time-varying plant – the biogas production rate in the anaerobic digestion of organic waste in waste water treatment. The main contributions are the design of the SI FC, the study of the closed loop control system performance and the estimation of the advantages of the SI FC system in comparison to other s...
Severe soil organic carbon (SOC) depletion is a major constraint in rainfed agroecosystems in India because it directly influences soil quality, crop productivity and sustainability. The magnitude of soil organic, inorganic and total carbon stocks in the semi-arid bioclimate is estimated at 2.9, 1.9 and 4.8 Pg respectively. Sorghum, finger millet, pearl millet, maize, rice, groundnut, soybean, ...
This Paper has used a multisectoral input-output model of Iranian economy to examine the ability of different sectors of economy to create jobs per unit of output as well as capital. The results reveal that there is no conflict in a growth strategy that simultaneously attempts to improve efficiency i.e. reallocating production to sectors with low DRCs, equity and job creation. Although sectoral...
Different approaches with regard to environmental protection and mitigation of negative impacts of development plans have been proposed during past decades. Organic agriculture as a production system is one of these. It applies minimum amount of artificial fertilizer, pesticides and additive hormones input. Taking into consideration Iran’s specific geographic, economic and social conditions, th...
