Land use changes are one of the factors leading to the disturbance of existing equilibrium in the ecosystem, and as a result several undesirable processes might negatively influence the soil functions. Despite many investigations where different aspects of soil quality in relation to land use change are studied there is not unequivocal conception and explanation which could be applicable for all situations. Differences in soil formation, diversity of abiotic and biotic conditions, and management practice stimulate or hinder changes which are going on in soil after radical alteration of land use pattern. In many countries, including Latvia, great emphasis is put on energetic crops. Availability of productive land not used for agriculture, climate, and water resources are advantages for development of this sector. But necessity for intensive use of fertilisers, other chemicals, heavy field machinery, and radical changes in organic matter accumulation and turnover of plant nutrients are risks which should be foreseen and studied. The goal is to accumulate the advanced information for decision support as well as to develop an effective soil monitoring framework to control the situation. The present article gives a literature review and analysis of information accumulated in research publications to point out aspects which could be relevant for Latvia situation. This is the second article (the first one see on pp. 1–17 of the current issue) devoted to the possible effects of land use changes on soil quality and environmental risks.
