“…The increase in DM production in line with the increase of nutrient application highlights that soil reserves in chemical elements are not enough for this mixture thus treatments are required for achieving optimum productivity. Similar observations were made also by Vasileva (2015) who pointed out that one of the advantages of using organic fertilizers is releasing more nutrients in root zone of plants.…”

The effect of different technological conditions on forage yield, growth behavior and competition ability of ryegrass, red clover and their mixture was analyzed. The results showed that red clover makes better use of the nutrition space in the case of variants sown in mixture with Italian ryegrass than in the monoculture, independent of the density of the plants or fertilization regime. The highest DM production was obtained at the mixture formed by red clover and Italian ryegrass on the variants sown on 12.5 cm distance between rows, the increase of the nutrition space being directly proportional to the decrease of the DM production in the case of this forage mixture.

“…In previously published authors' works [3][4][5], we noted a peat drawdown of 54...67 cm, the appearance of wet spots indicating secondary waterlogging, deterioration of water-physical properties, an increase in ash content and the surface sand deposits. All this led to the development of the motley topsoil, reduction of peat layer thickness to 116 cm, loss of organic matter by 120 t/ha and other negative changes.…”

The results of many years of original research based on soil-ecological monitoring showed the development of degradation processes of previously drained peat soils of the Ryazan Meshchera. Structural amelioration (sanding) of peat soils had some positive effect. The aim of the research was to study the properties of the dried peat soil at reclamation site Tinki-II in the settlement of Polkovo, Ryazan District of Ryazan Region, as a result of sanding. The most common type of German mixed-layer sanding was used in investigations. The methodology was based on the principle of comparing the state of dried peat soil before and after sanding. The content of the less than 0.01 mm fractions was 4.3 %, the rest consisted of particles from 0.25 to 0.05 mm; the pH of the salt extract was 5.7. Mineral fertilizers were applied in the experiment in small quantities: ammonium nitrate -180 g, superphosphate -185 g and potassium sulfate -260 g. The water supply was atmospheric-ground. Variant 2 was more effectivesanding with a dose of 1200 t/ha for sluicing and maintaining GWL = 90 cm, as evidenced by improved water-physical properties of the soil: the total porosity increased by 5 %; the total water capacity decreased from 270 to 70%, that was almost 4 times.

“…Among internal impacts, fallen leaves, fruiting, and branching affect the biomass allocation of trees and then influence the growth of roots. Moreover, irrigation, fertilization, and pruning affect root distribution during gardening maintenance [34]. In addition to the root system, factors affecting soil total porosity and non-capillary porosity include organic matter, soil arrangement, structure, cultivation, rainfall, and fertilization [10].…”

To explore the relationship between arbor root density and corresponding physical soil properties (total porosity, non-capillary porosity, specific weight, bulk density, moisture content, and permeability), noninvasive methods such as Tree Radar Unit (TRU) were utilized to detect the root systems of 10 species of tree that are commonly used in Shanghai green spaces with more than 70% frequency of occurrence. Using TRU and soil investigation, root density and soil porous features were determined for different tree species, depth slices, and distances. The relationships among root density, soil porosity, and non-capillary porosity were identified using variance analysis and regression analysis. The results indicated that root density decreased with increasing distance from the trunk and soil depth. Soil porosity and non-capillary porosity had significantly positive and linear correlations with root density. Compared with lawns, trees such as Zelkova serrata, Koelreuteria paniculata, Cinnamomum camphora, and Metasequoia glyptostroboides had the greatest effects on soil improvement through soil porosity and non-capillary porosity. Due to the spatial distribution of root systems, trees could be divided into three types based on their influence at various soil depths.
