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.
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.
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.
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.
Degraded territory is land which has been damaged by either industrial and other activities or no activities at all to the stage where any economic activity is impossible unless special renewable measures are implemented.
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.
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 Latvia University of Life Sciences and Technologies (until March 6, 2018 – Latvia University of Agriculture (LLU); Latvian: Latvijas Lauksaimniecības universitāte; LLU) is a university in Jelgava, Latvia, specializing in agricultural science, forestry, food technology and related areas.
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.
In the administrative territories with small number of population, deficiency of infrastructure and resources for municipalities’ function can be observed. According to this, already in the 90ties, reform of local governments was initiated in Latvia. The cabinet, basing on principles of local governments in European Charter (1985), accepted conception of the reform.
