1. Specific fertilization practices reveal important insights into the complex interaction between microbes and enzymes in soils of different farming systemsMaša Kozmos, Ana Štuhec, Eva Tratnik, Tomaž Langerholc, 2024, original scientific article Abstract: The interaction of microorganisms and their enzyme activity is one of the key indicators for a comprehensive measurement of soil health. The aim of this study was to determine significant correlations between different soil microorganisms and enzyme activities of β-glucosidase, N-acetyl-glucosaminidase, urease, arylamidase, phosphatase, acid phosphatase, alkaline phosphatase, and arylsulfatase after supplementation with standard fertilizer, spent mushroom substrate and composed fertilizer in soils from conventional–integrated, organic and biodynamic farming. Samples were grouped according to the farming system and fertilization for all seasons. The biodynamic farm was the least affected by the different fertilizations, except for standard fertilization. Standard fertilizer caused negative correlations between the actinomycetes and the arylsulfatase in organic and biodynamic farms. The same fertilization affected the actinomycetes/phosphatase relationship differently, regardless of the basic soil structure. Actinomycetes correlated positively with acid phosphatase and urease in conventional–integrated and biodynamic farms after spent mushroom substrate, respectively. Arylamidase activity in relation to total microorganisms responded to fertilization with standard fertilizer and spent mushroom substrate independently of the basic soil structure. Fertilization can influence the soil microbe/enzyme relationships in different soils. Regardless of the basic soil structure, some of these relationships could be important indicators for further studies.

2. Agroecology in SloveniaAna Vovk, 2016, review article Abstract: The article presents to agroecology (AE) as a sustainable approach in Slovenia. AE deals with contents as the ecology in agriculture, organic farming, sustainable agriculture, green agriculture, permaculture, ecoremediations, integrated farming and natural agriculture. According to the official definition the term AE means the use of traditional practices that are consistent with the characteristics of the local environment and do not limit only on food production, but also on food processing (recipes), products made from natural materials, especially wood, stone and construction as well as on ways of sustainable relationship to nature (water storage, attitude to water use, attitude to soil, shallow ploughing, attitudes toward animals, plants). We have discovered the concept of AE and its use in Slovenia. In Slovenia the term is limited to the understanding of the importance ecology in agriculture. The representatives of the Slovenian institutions of the Chamber of agriculture and forestry who have a similar project on the topic of AE, designed for agricultural consultants, having described different form of AE. In project Agroecology at the Faculty of Arts we develop educational modules for teaching AE in practise.

3. Ecological efficiency of production and the ecological footprint of organic agricultureMatjaž Turinek, Maja Turinek, Silva Grobelnik Mlakar, Franc Bavec, Martina Bavec, 2010, review article Abstract: The rising energy prices and climatic changes have intensified the search for alternative farming systems where energy consumption per unit would be lowered. A long-term field trial, started in 2007 at the University of Maribor, focuses on food quality and the ecological foot print of convential (CON), integrated (INT), organic (ORG) anf biodynamic (BD) systems in production of wheat (Triticum aestivum L.) and spelt (Triticum spelta L.), mainly due to the non-use of external synthetic production factors. When yields are added to the equation, the ORG and BD systems emerge also as more efficient per unit of land area. Thus, the ORG and BD system present viable alternatives for reducing the impact of agriculture on climate change, while ensuring a more sustainable food security.

4. Organic farming: a solution to agriculture crisis or a "new" trend to healthy eating? : an overview of French and British farmersAnnabelle Boulay, 2010, review article Abstract: In recent years, the market for organic farming has significantly increased in response to concerns over food quality and environmental matters. Organic food is quite attractive for consumers and is often associated to quality, healthy and natural products in opposition to the more processed and artificial conventional food. Yet, farmers are less enthusiastic about this concept. This paper, issued from a survey with dairy farmers in two dairy areas in France (January 2000) and the UK (July 2002), review farmers attitude towards organic farming. Only a minority of farmers were in favour of organic farming while the others had concerns about organic farming as its concept goes against their belief: a farmer must produce food for the nation.
