In the conditions of the Republic of Belarus there were examined different formulations of a notion and term of 'land use', there was presented its content taking into account modern conditions. There was shown the notion and content of intra-farm land use planning of agricultural organizations; its content updated with the issues on ecologization of land use planning. There was suggested an energy approach to the economic estimation of taken project decisions made in land use planning.

The Mountain Pine Beetle epidemic in Alberta has been substantial, with several forest products companies facing a potential decrease in fibre supply as a result. Accurate forest inventory is integral in developing management strategies that effectively address the infestation. Within this context, forest inventory must provide enough species composition detail to allow the design of appropriate harvesting activities.

Land tenure relations have both social and environmental implications, ranging from potential power issues to land stewardship. Drawing upon survey data of landowners collected in the Great Lakes Basin of the U.S., this study builds upon existing research by examining absentee landlords of agricultural land—a vastly understudied but growing category of landowners.

In article is devoted to problems of land relations in agriculture, which provides an analysis of the nature this dynamics in recent decades, assess the rationality of land use in the context of globalization and offers an innovative solution for forming a model of land relations in agriculture. The authors is a traced the cyclic processes in the history of the development of land and property relations, assesses the present stage of the next cycle and are historical parallels in socio-economic development.

Soil microbes play major agricultural functions such as the transformation of soil organic matter into plant fertilizers. The effects of agricultural practices on soil microbes at the scale of plots, from meters to hectare, are well documented. However, the impact at soil microscale, from micrometers to millimeters, is much less known. Therefore, we studied bacterial community density and diversity at microscale in crop soil under grassland, tillage, and no tillage.

The weedy Setaria species (giant, green, yellow, knotroot, and bristly foxtail) compose one of the worst weed groups interfering with world agriculture and in other disturbed and managed habitats. These species, together with their crop counterparts (foxtail millet, korali), form the foxtail species-group (spp.-gp). Five successive waves of Setaria spp. invasion from preagricultural times to the present have resulted in widespread infestation of the disturbed, arable, temperate regions of the earth. These invasions have resulted in considerable economic and environmental costs.

Agricultural production is based on environmental natural resources, that is soil, water, air and the whole landscape with its biodiversity. The using with resources of soil should therefore be balanced which would combine the tasks of farmhold utilizing from both economical, social and environmental protection point of views. Principles these be realized in special means by ecological agriculture as sustainable system of food production.
