In the conditions of the Republic of Belarus there were presented research results of the study with the aim to offer a number of new criteria for quantitative diagnostics degraded peat soils, which were the result of a study of chemical and biological properties of peat soils of different stages of evolution.

The article presents an analysis of productivity and consumption of natural grass pastures under the influence of forestbelts and water-detention shafts depending on snowfall winters, springs of water content, moisture of the growing seasonregrowth of grasses

В статье представлен анализ продуктивности и водопотребления естественного травостоя пастбищ подвлиянием лесных полос и водозадерживающих валов в зависимости от снежности зим, водности весен, увлажнениявегетационного периода отрастания трав

Both forestry theory and practice have proved that amelioration favours the growth of forest stands significantly. The growing stock increases even 10 times, if the amelioration system is well-functioning. Joint Stock Company Latvia State Forests that is managing half of forests in Latvia has started renovation of old amelioration systems aiming to improve the productivity of state owned forests in Latvia. In order to evaluate the impact of the renovation of the old amelioration systems, a tree ring width in 7 pine stands, 5 spruce stands and 3 birch stands was analysed.

Substantiated was the use of formal methods in the development of adaptive-landscape farming systems. The study was conducted in the Tver region. The article proposes to determine the values of macroagrogeosystem production potential (PP) by calculating integrated productivity parameters of different locations. There were distinguished 11 types of landscapes within the Tver region. The values of integrated indices were calculated.

Some scenarios of probable climatic changes in the Czech Republic and the anticipated effect of these changes on the components of the hydrologic water discharge from drained agricultural and forest catchments are studied. The function of drainage systems on selected experimental lands is examined. The effect of climatic changes on the hydrologic balance and/or on the runoff from the catchments significantly varies up to +/-150% provided that we compare the average runoff.

Studied was the impact of phosphogypsum and phosphogypsum-containig amendments on the properties of ordinary chernozem degraded due to irrigation with mineralized water (1.7-2.0 g/l), as well as on the crop yield. It was established the decreasing of soil sodicity by 50% upon applying the total calculated dose of phosphogypsum (10 t/ha), the increasing of calcium content in soil exchangeable complex up to optimal parameters (85%), the achieving of good water-stability of soil.

One-year field experiment with spring barley (Hordeum vulgare L.) was carried out to evaluate the effect of biochar amendment on the pH of Orthic Luvisol at the research site located in western Slovakia (lat. 48° 19′ 00″

The aim of the research is to investigate technological process of growing of 9 promising soya cultivars, obtained from 5 originators, in dry steppe zone of Volga region (Saratov area) under irrigation. Experiment observations were done in 2012-2014 in accordance with standard techniques of experimental work and schedule of study. The experiment investigations were carried out through all elements of technological process.

In the conditions of the Republic of Belarus there were presented theoretical statements and methodical approaches to the improvement of the use of lands and organization of the territory of agricultural organizations in conditions of ecologization of land use. There were formulated the notion and tasks of improvement of the use of lands of agricultural organizations.

Objective scientific characteristics of present reclamation systems of Belarus have been done. Structure of reclamation lands has been analyzed. Distribution of reclaimed lands according to the types of irrigation and drainage systems has been presented. Reasons of insufficient usage of reclamation systems have been discovered. Mistakes that had been made on large-scale reclamation building have been estimated. Review of realization of the Republican programme “Preservation and usage of reclaimed lands” for 2001-2005 has been made.

There are around 400,000 hectares of soils with heavy mechanical composition, and the greatest part of the production area is under crops. The long term soil tillage by conventional methods (using plough) and a large number of passages of mechanization in this type of soil causes a subarable waterproof layer, with a lot of negative consequences in a crop production.
