The research aim is to identify the growth pace, productivity and quality of Scots pine in age classes I-IX in the forest type Callunoso-sphagnosa. Scots pine (Pinus sylvestris L.), which occupies 35% of the total forest area, is the most significant tree species in Latvia from the forestry perspective, yet the growth pace, productivity and quality of the species in the forest type Callunoso-sphagnosa have been little researched. The forest type Callunoso-sphagnosa is rarely found in Latvia; it is poor in nutrient...

Population densities of cervids (moose, red deer, roe deer) are increasing sharply and consistently in Latvia since middle of 1990th, causing more damages in young forest stands. It is a result of changes in farming practices well as game-management strategies by hunting clubs. Many hunting clubs tend to keep or increase the population densities of cervids with different methods, including supplemental feeding. The aim of the study is to evaluate the impact of the proximity of supplemental feeding sites on browsin...

The aim of the study is to characterise the provenances of lodgepole pine ? a potential alternative to Scots pine in sandy soils ? and to recommend the most suitable ones for establishment of plantations in hemiboreal forests in Latvia. To achieve it, data on tree parameters (height, breast height diameter, quality traits, damage by cervids) from provenances originating from North America (53?-61?N, 118?-135?W) were collected in trial in central part of Latvia. The data were processed employing parametric methods....

The use of bioenergy is gradually increasing, so are the number of different technologies to produce it. Particularly during the last years, new biogas plants had been built across Latvia to ensure more efficient use of farming and other agronomic waste or by-products. The aim of the research is to determine occupational risk factors at biogas plants in Latvia. The research summarises the risk factors of the biogas plant environment, compares the results of observations of biogas plants, performs a survey and an a...

In Latvia, according to Central Statistical Bureau data (2018), the agricultural industry employed 76.4 thou. employees in the main job as well as 49.4 thou. seasonal workers. For this reason, this industry plays an essential role in the national economy, and with the industry developing, labour-saving technologies are increasingly introduced to reduce manual work in agriculture. Besides, mineral fertilisers and plant protection products are intensively applied (organic farms are an exception) in order to increase...
