The research aim is to identify the effect of a surface forest fire on the productivity and viability of Scots pine (Pinus sylvestris L.) in a 23-year-old stand. The research was done two years after a surface fire that occurred in 2015 in a 20-year-old stand, establishing sample plots both in the area subject to the fire and the fire-undamaged area as well as in a pine stand of identical age that had not suffered from a forest fire. The research measured the dendrometric characteristics of trees (height, diameter...

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...

The North Caucasus Federal district is one of the most difficult in terms of its geological location. So, more than a third of the district is mountainous territory. The landslide process is developed in almost all areas. Landslide-bulk processes within the GFCS are mainly developed within the Greater Caucasus. Agriculture forms the basis of the economic complex and in the agro-industrial complex 53 per cent are crop and 47 per cent are livestock. The main directions of development in crop production are the produ...

The perforation channels are the only conduits between the reservoir in production and the producing well, so it is quite obvious that their parameters seriously affect the productivity. Under this highly volatile oil price environment aiming for the best productivity has the highest priority. For this reason, the need for understanding the effect of the perforation parameters on the inflow is urgent. In the previous years, Pasztor has proposed a new concept to calculate the pressure drop caused by the perforation...

The Kaizen concept represents a continuous improvement approach to exploiting the potential of human capital. Employees are the bearers and co-creators of values and their performance contributes to increasing efficiency and therefore education strategies need to be directed to the education of university students, potential workers in enterprises in the labor market. In education, there is scope for using the Kaizen concept as an incentive tool that increases the quality of human potential and the level of human ...

Studies were conducted in an intensive fruit-bearing apple orchard in the South of Russia in the Chechen Republic. Layout scheme - 3,75?1,5 m, the formation of trees - a slender spindle. The object of study were apple cultivars Renet Simirenko (control), Granny Smith, Florina (M9). The main soil cultivation (autumn plowing) was carried out once in 3-4 years by garden plows or plows-lushmen at a depth of 14-16 to 18-20 cm in row-spacing and 6-12 cm in the trenches. Cropping blocks in an intensive garden with dwarf ...

There are areas of extrazonal relic steppes on the territory of Yakutia in the tundra and taiga zones. They are the most extensive in central Yakutia, and sporadic squares of steppes are located in the north, in the Yana, Indigirka and Kolyma rivers basins. There are growing the xerophytic steppe plants which are separated from the main range, characteristic of the Transbaikalia and Mongolia steppes, as well as a number of invertebrate and vertebrate species of animals associated with their origin with the steppe ...

In the article the main results of study in the field of weather and climate risks evalua-tion for the territory of the Belgorod oblast are summarized. The directions of these risks management at the regional level are determined. Against the backdrop of global climate change, the volatility of agricultural and meteor-ological conditions not only continues but also worsens. The observed increase in the frequency of occurrence of hazardous agro-meteorological phenomena in the region is determined by climatic change...
