    Soil samples in 349  sampling plots were obtained within the LUCAS project in 2009; from these, 205 soil samples were collected in agricultural lands (grasslands, arable lands, grasslands overgrown by trees and shrubs), and 133 soil samples were obtained in forests (deciduous, coniferous and mixed forests), as well as 7 soil samples–in scrublands.

    Research on the sustainable use of the soil as the main agricultural resource employing different field crop rotations and tillage systems was started in 2009. The influence of new technologies on sustainable output of agricultural raw materials used for safe and good quality food and feed production was studied at the Latvia University of Agriculture, Study and Research Farm “Peterlauki” where long-term field experimental plots were established specially for this purpose. Complex investigation of the soils at the experimental plots was performed.

    In the recent years the issue of optimal size of the utilised agricultural area and its accessibility in particular regions has gained increased importance. Total area, types and conditions of the utilised agricultural area are essential to shaping and implementation of the Common Agricultural Policy. This research comprises investigation of the single area payment and the area payments done in scope of the Rural Development Programme for the time frame of 2007 – 2011.

    In this research the potential of grain production increase in Latvia is analysed. The land use analysis show that even in some nearest years it is possible to increase grain production by 400-500 thousand tons compared by 2010 level, but in 10 years period – by 1 million tons or more. This is due to increase both areas and yield. It is assessed during of the research that price above 90 Lats/t for wheat and above 80 Lats/t for barley, rye and oats stimulates grain production. Also some additional state regulation measures are recommended in the research.

    The results of birth growth investigation in the 9 year old plantation on the abandoned podzolic soils of agriculture lands are assumed. The planting density was 1100; 1600; 2500; 5000 and 1000 plants per hectare. The average heights have reached 5.31 and 5.36 m, but average DBH 5.38 and 5.36 cm in the plots with 10 000 and 5000 trees per hectare accordingly. The average height has reached 6.47; 6.65 and 6.73 m but average DBH 7.17; 6.67 and 7.38 cm in the plots with 2500; 1000 and 111 trees per hectare accordingly.

    The aim of this thesis is to evaluate the influence of edge effect on vegetation succession in black alder forests. 30 permanent study plots with size of 20×50 m were established with strips at several distances from the edge towards the center of the stand. Stands in study plots fell into three categories – with adjacent clearcut to S or SW created up to 10, 20-40 or more than 41 year ago. In all study plots living trees and dead wood was measured and vegetation was described by layers and the presence of rare epiphytic lichens was recorded.

    Attempts to estimate the allowable maximum population density is well known in the history of game management in Latvia. Relatively permanent environmental features (e. g. landscape and forest structure) have been used for the assessment of carrying capacity of hunting grounds. Amount of the available winter feed was considered as a limiting factor for major game species in each landscape unit and forest type. While focusing on the actual abundance of feed, many other factors, including mutual interaction among species and populations, were overlooked.

    In the administrative territories with small number of population, deficiency of infrastructure and resources for municipalities’ function can be observed.
