Opis:: Water erosion in mountainous areas is a major problem, especially on steep slopes exposed to intense precipitation. This paper presents the analysis of the topsoil loss using the SWAT (Soil and Water Assessment Tool) model. The SWAT model is a deterministic catchment model with a daily time step. It was designed to anticipate changes taking place in the catchment area, such as climate change and changes in land use and development, including the quantity and quality of water resources, soil erosion and agricultural production. In addition to hydrological and environmental aspects, the SWAT model is used to address socio-economic and demographic issues, such as water supply and food production. This program is integrated with QGIS software. The results were evaluated using the following statistical coefficients: determination (R2), Nash-Sutcliff model efficiency (NS), and percentage deviation index (PBIAS). An assessment of modelling results was made in terms of their variation according to different land cover scenarios. In the case of the scenario with no change in use, the average annual loss of topsoil (average upland sediment yield) was found to be 14.3 Mg∙ha-1. The maximum upland sediment yield was 94.6 Mg∙ha-1. On the other hand, there is an accumulation of soil material in the lower part of the catchment (in-stream sediment change), on average 13.27 Mg∙ha-1 per year.

Opis:: The article presents the results of monitoring the aftereffect of the use of excessive zonal doses of mineral fertilisers on soil contamination with heavy metals (HM). With traditional soybean cultivation technology, the level of soil contamination when applying excessive doses (N60 P180 K90) of fertilisers is quite high and indicates violations of the ecological balance of the agroecosystem. By the nature of the accumulation of heavy metals in meadow-chestnut soil, depending on the application of the studied doses (P60 K30, N30 P60 K30, N60 P180K90) of fertiliser, the content of HM (Pb, Zn, Cd) increases. The greatest contamination of the soil with Cu was revealed, the content of which increases to 3.2 mg∙kg-1 of soil, which is higher than the threshold of the maximum permissible concentration (MPC) - 3.0 mg∙kg-1. According to the level of contamination of the soil with copper, it belongs to the highly dangerous classes. In a comparative assessment of the level of soil contamination with HM, optimal norms of mineral fertilisers have been established, namely, against the background of effective resource-saving technology for growing soybeans. The application of fertilisers at a dose of P60 K30 and N30 P60 K30 does not significantly affect the level of soil contamination with HM, optimises the ecological state and nutrient regime of the soil, preserves and restores soil fertility indicators, and increases soybean productivity. This resource-saving technology provides a safe environment for soybean cultivation and a significant increase of 34.5-38.6% in crop productivity (0.53-0.76 Mg∙ha-1) and yield (2.57 Mg∙ha-1).

Opis:: Improving water productivity (WP) through deficit irrigation is crucial in water-scarce areas. To practice deficit irrigation, the optimum level of water deficit that maximizes WP must be investigated. In this study, a field experiment was conducted to examine WP of the three treatments at available soil water depletion percentage (P_i) of 25% (reference), 45% and 65% using a drip irrigation system. Treatments were arranged in a randomized complete block design. The water deficit was allowed throughout the growth stages after transplanting except for the first 15 days of equal amounts of irrigations during the initial growth stage and 20 days enough spring season rainfall during bulb enlargement periods. Physical WP in terms of water use efficiency (WUEf) for treatments T1, T2, and T3 was 9.44 kg∙m^–3, 11 kg∙m^–3 and 10.6 kg∙m^–3 for marketable yields. The WUEf and economic water productivity were significantly improved by T2 and T3. The WUEf difference between T2 and T3 was insignificant. However, T2 can be selected as an optimal irrigation level. Hence, deficit irrigation scheduling is an important approach for maximizing WP in areas where water is the main constraint for crop production. The planting dates should be scheduled such that the peak water requirement periods coincide with the rainy system.

Opis:: The aims of this study were to evaluate five infiltration models for mineral soils in the tropics with different land use types, such as settlements, plantations, rice fields, and forests. The infiltration models evaluated were Green–Ampt, Kostiakov, Kostiakov–Lewis, Philip, and Horton. The research was conducted at the Amprong watershed, Malang, Indonesia. The infiltration rate of the thirteen soil samples was analysed. The infiltration was tested using Turf-Tech infiltrometer. Moreover, each soil sample was tested in terms of the bulk density, specific gravity, porosity, soil moisture, and soil texture. The results of the study indicate that there is no significant difference (α = 5%) in the infiltration rate among the five models of infiltration. The infiltration rate in the study site was considered fast. Three models exhibiting the best performance are Kostiakov, Kostiakov–Lewis, and Horton model, respectively. The highest infiltration rate occurred in the forest land use while the lowest occurred in the rice field land use. The results of this study suggest that the infiltration model parameters correlate closely with the initial infiltration rate (fo) and the final infiltration rate (fc). In other words there is a correlation between the soil's ability to absorb water (representing the capillary force or horizontal flow) at the beginning of the infiltration (fo) and the gravity or the vertical flow upon reaching the final infiltration rate (fc).
Celem badań prezentowanych w niniejszej pracy była ocena pięciu modeli infiltracji opracowanych dla gleb mineralnych o różnym typie użytkowania w tropikach, takich jak: obszary zabudowane, plantacje, pola ryżowe i lasy. Oceniano modele Greena–Ampta, Kostiakova, Kostiakova–Lewisa, Philipa i Hortona. Badania prowadzono w zlewni Amprong, Malang w Indonezji. Analizowano tempo infiltracji w trzynastu próbkach glebowych z użyciem infiltrometru Turf-Tech. Ponadto w każdej próbce gleby analizowano gęstość objętościową, ciężar właściwy, porowatość, wilgotność gleby i skład granulometryczny. Wyniki badań dowiodły, że nie ma istotnej różnicy w tempie infiltracji (α = 5%) obliczonej za pomocą wymienionych pięciu modeli. Uznano, że tempo infiltracji było duże. Trzy modele, kolejno: Kostiakova, Kostiakova–Lewisa i Hortona okazały się najbardziej odpowiednie. Największe tempo infiltracji stwierdzono w glebach leśnych, a najmniejsze w glebach pod polami ryżowymi. Wyniki badań sugerują, że parametry modelu infiltracji są ściśle skorelowane z początkowym (fo) i końcowym (fc) tempem infiltracji. Innymi słowy, istnieje korelacja między zdolnością gleby do absorbowania wody (reprezentowana przez siły kapilarne i przepływ poziomy) na początku infiltracji (fo) oraz siłą ciążenia i przepływem pionowym po osiągnięciu końcowego tempa infiltracji (fc).

Opis:: In furrow irrigation, the maximum lateral movement of water in ridges is more desirable than the vertical downward movement. This can be achieved by compacting the furrows. Thus, the study examines the impact on furrow soil compaction by tractor wheel trafficking during mechanical operations in the different soil types. In this experiment, the three-wheel tractor compaction includes: 1) control (no soil compaction), 2) compaction through 3-wheel tractor passes, and 3) compaction through 6-wheel passes under three different soil textural classes such as: clay loam, silty clay loam and silty loam soils. The impact of various treatments on clay loam, silty clay loam, and silty loam under 3- and 6-wheel passes showed increased bulk density (7–12%), field capacity (9–19%), ridge storage efficiency (35–38%), water use efficiency (16–20.5%) and decreased soil porosity (7–16%), infiltration (8–20%), and furrow storage efficiency (28–41%) over the control. This study shows comparable results of 6-passes with other studies in which more than 6-passes were used to compact the soil. This study suggested that farmers can maximise water use efficiency by compacting their furrows using 6-passes tractor trafficking.

Opis:: The article is devoted to a topical scientific problem in modern conditions – valuation of land in Ukraine. The imperfection of the existing approaches requires further research on the changing conditions of land use and their impact on land pricing. A methodology for determining the market value of reclaimed land based on a differentiated assessment of its productivity through crop yields is proposed, taking into account natural and climatic zones and other conditions of a particular region. The basis of the methodology is the application of long-term forecast and a set of forecast and simulation models, in particular the model of area climatic conditions and the model of water regime and water regulation technologies on reclaimed land. At that the crop yield model as a complex multiplicative type model takes into account all main factors influencing crop yield formation: weather, climatic and soil conditions, cultivation techniques, water regime of reclaimed land, etc. The proposed approaches were tested by the method of large-scale machine experiment using a land plot in the zone of Western Polissya of Ukraine as the example. The obtained results indicate that there is a differentiation in land value, which is a proportional derivative of the yield of cultivated crops depending on the conditions of their cultivation. The variation range of the studied indicators in relative form by the ratio of maximum and minimum values to the weighted average value is for cultivated crops – 393%, and for the above soils – 44.6%. Thus, within one object, the estimated value of land in view of available soils and cultivated crops varies from USD2456∙ha–1 to USD4005 ∙ ha–1, averaging USD3522 ∙ ha–1 .

Opis:: The article considered the influence the various types of land use on microbial activity of soils and thus using this parameter as a universal test of soil quality. Samples for soil respiration studies were taken from agricultural areas, meadows, forests and urban areas (estate cottages). All samples were subjected to the same analytical procedure and the method of measurement was followed by a Substrate-Induced Respiration (SIR) method. Since all the samples were from neighbouring regions and were characterized by similar soil parameters, the obtained results allowed to assess the quality of the soil environment of the surveyed area and to evaluate the total rating of whole area. The obtained results allowed to observe slight divergences between soil samples taken from areas of different use. And although statistically, in this case, these differences were not significant, the characteristics of the respiration curves clearly indicate that there is a dependency between the form of use and the size and rate of soil respiration. In addition, the results have shown that single family housing does not exhibit as much anthropopression to the soil environment as it might seem.
W artykule rozpatrywano wpływ różnego rodzaju użytkowania terenu na aktywność mikrobiologiczną gleb i tym samym możliwość wykorzystania tego parametru jako uniwersalnego testu jakości podłoża glebowego. Do badań respiracji glebowej wykorzystano próbki pobrane z terenów użytkowanych rolniczo, łąk, lasów oraz terenów zurbanizowanych (zabudowa domków jednorodzinnych). Wszystkie próbki poddano identycznej procedurze analitycznej, a jako metodę pomiaru zastosowano metodę indukowanej substratem respiracji (ang. SIR – Substrate- Induced Respiration). Ponieważ wszystkie próbki pochodziły z sąsiadujących ze sobą rejonów i charakteryzowały się podobnymi parametrami glebowymi, uzyskane wyniki umożliwiły ocenę jakości środowiska glebowego badanego terenu i dokonanie oceny sumarycznej rejonu badań. Uzyskane wyniki pozwoliły zaobserwować niewielkie rozbieżności między próbkami glebowymi pobranymi z terenów o różnej formie użytkowania. Statystycznie różnice te nie były istotne, jednak na podstawie charakterystyki krzywych respiracji jednoznacznie można stwierdzić, że między formą użytkowania a wielkością i szybkością respiracji glebowej zaznacza się pewna zależność. Dodatkowo uzyskane wyniki dały podstawy do stwierdzenia, że osiedla domków jednorodzinnych nie wykazują tak dużej antropopresji na środowisko glebowe, jak mogłoby się wydawać.
