This review deals with the influence of organic farming, as well as with the effects the conversion of conventional to ecological farming systems have had on the quality of soil and biodiversity. Organic farming is defined as a system in which crop and animal production must be balanced, and all means of production needed for plant and animal breeding are produced within the farm. Organic farming prohibits the use of pesticides and artificial fertilizers, therefore is widely perceived as being more environmentally friendly than conventional farming. Organic farming is also identified with the production of high-quality food, with the improvement of animal welfare, as well as associated with rural development. This type of farming aims to sustain the quality and fertility of the soil and to maintain key ecological soil functions. The presented overview shows that organic farming leads to higher soil quality and more biological activity in soil than conventional farming. A growing number of studies also show that organic farming can have a positive effect on ecosystems by increasing biological diversity and by a diversification of the agricultural landscape. This is to prevent the loss of the natural habitat of many wild plant and animal species.

The flora of the former Łęczyca iron ore dumps Iron ore mines of the Łęczyca region started operating in the sixties and seventies of the 20th century and brought about considerable changes in the agricultural landscape of the town of Łęczyca and its vicinity. As a result of the ore exploitation, rock dumps as well as local depressions were created there. The subject of the present research was flora occurring in areas transformed by iron ore mining in the Łęczyca region. The flora is of spontaneous and anthropogenic (as a result of planting - reclamation) character. The results of the conducted research indicate that areas transformed by mining significantly increase their biological diversity.

Abstract Traditional agricultural landscapes (TAL) are landscapes in which primarily traditional sustainable agricultural practices are currently carried out and where biological diversity is conserved thereby. The objective of this paper is to evaluate the extension of traditional landscape structures and their relationship to geological substrate and slope processes (landslides). The evaluation was concentrated on two types of TAL (extended to Kysuce region): TAL with dispersed settlements (subtype 1a and b) and TAL of arable-land, grasslands and pastures (subtype 4a and b). Localities with typical dispersed settlements of subtype 1a mostly occur on Zlin formation and cover 707.9 ha. On the deluvial formation, this type extends to 531.8 ha and on the Solaň formation, to 403.6 ha. The active landslides are mostly represented in the TAL of subtype 4a (cadastral areas of Čadca and Oščadnica villages), of subtype 4b (cadastral areas of Riečnica and Svrčinovec villages) and of subtype 1a (cadastral area of Svrčinovec village). The largest representation of potential landslides is on the subtype 4a, subtype 1a and subtype 4b.

<p>The coffee plantations have been considered refuges of biological diversity, the faunistic studies in this type of agroecosystems are of great importance for the knowledge and conservation of the fauna. The objective of the present study was to know the wild fauna and the status of conservation of the species present in the farm "El Chorrito". Sixty-one species were recorded, 24 corresponding to avifauna, 20 to herpetofauna and 17 to mastofauna; this represents 3.4% of the avifauna reported for the Estado de Veracruz, 11.11% of the herpetofauna reported for the country's coffee plantations and 3.21% of the 529 species of mammals reported for Mexico; 18 of these are found in the NOM-059, seven in the IUCN red list and 18 in the CITES appendix. The presence of species with some sensitivity to disturbance is similar in an undisturbed habitat and a farm. The coffee plantations are an excellent habitat because the animals find shelter and constant food, which suggests a high degree of conservation of the place. Small mammals and birds are part of the biological groups that are considered ecological indicators of the role that coffee plantations play in the protection of habitat biodiversity, as a result of different management or degree of conservation. Four species were observed on the farm that can be considered as detector species since they can provide information on habitat quality. It can be concluded that there is a similarity with the surrounding forest in terms of fauna.</p>
