Abstract Ponding time is the period from the beginning of rainfall/infiltration until the occurrence of ponding. This paper aims to determine the infiltration rate and ponding time on different land uses, such as open fields, residential, agriculture, and vegetation. This research was conducted in one of the watersheds in the Brantas River Basin, namely the Lesti River Basin, which is administratively included in the Malang Regency, East Java. The Lesti River is one of the tributaries of the Brantas River, which originates around Mount Semeru, a very intensive area for planting rice, sugar cane, and coffee. Infiltration data were collected at 35 points using a double-ring infiltrometer spread across the Lesti watershed with Andosol, Mediterranean, and Regosol soil types. At the same time, ponding time was obtained from infiltration measurements in the field using the flooding method. The physical properties of the soils were tested in the laboratory to obtain water content, porosity, and bulk density values. This study resulted in the infiltration rate and ponding time for each land use and shows how the physical properties of the soil affect the ponding time.

A infiltração consiste na entrada de água na camada superficial do solo. Este processo é influenciado por diversos fatores tais como: características da precipitação, condições físicas do solo e tipo de uso do solo. Os diferentes tipos de uso do solo em uma bacia hidrográfica indicam variações nas condições físicas do solo que podem alterar o processo de infiltração da água. Neste contento, este artigo teve como objetivo mensurar a infiltração de água no solo em uma bacia hidrográfica no município de Irati na Região Sudeste do Paraná com diferentes tipos de uso do solo. Realizamos duas campanhas de coleta de dados, uma no verão e outra no inverno. Para mensurar a infiltração da água no solo utilizamos um infiltrômetro de anéis concêntricos. Ao término do monitoramento concluímos que a taxa de infiltração é maior no período de inverno em todos os usos da terra. A agricultura indicou maior variação na infiltração entro os dois períodos de monitoramento devido ao manejo do solo. A área urbana indicou menor variação na infiltração, por não haver mudanças significativas no solo ao longo do ano. Abstract:The infiltration consists of the input of water into the soil. This process is influenced by several factors such as: characteristics of rainfall, soil physical conditions and land use type. The different types of land use in a watershed show variations in soil physical conditions that can alter the process of water infiltration. Therefore, this article has as objective to measure the infiltration of water in the soil in a watershed in the Municipality of Irati in the Southeast Region of Paraná with different types of land use. We carried out two campaigns of data collection, one in the summer and other in the winter. We used a concentric ring infiltrometer to measure the infiltration of water in soils. At the end of the monitoring we conclude that the rate of infiltration is higher in the winter period in all land uses. Agriculture indicated greater variation in infiltration between the two monitoring periods due to soil management. The urban area indicated less variation in the infiltration, as there were no significant changes in the soil during the year.Keywords: Infiltration rate; Land Use; Rural Area; Urban Area; Seasonality.

AbstractSoil physical properties and soil organic carbon (SOC) are considered as important factors of soil quality. Arable land, grassland, and forest land coexist in the saline-alkali reclamation area of the Yellow River Delta (YRD), China. Such different land uses strongly influence the services of ecosystem to induce soil degradation and carbon loss. The objective of this study is to evaluate the variation of soil texture, aggregates stability, and soil carbon affected by land uses. For each land use unit, we collected soil samples from five replicated plots from “S” shape soil profiles to the depth of 50 cm (0–5, 5–10, 10–20, 20–30, and 30–50 cm). The results showed that the grassland had the lowest overall sand content of 39.98–59.34% in the top 50 cm soil profile. The content of soil aggregates > 0.25 mm (R0.25), mean weight diameter and geometric mean diameter were significantly higher in grassland than those of the arable and forest land. R0.25, aggregate stability in arable land in the top 30 cm were higher than that of forest land, but lower in the soil profile below 20 cm, likely due to different root distribution and agricultural practices. The carbon management index (CMI) was considered as the most effective indicator of soil quality. The overall SOC content and CMI in arable land were almost the lowest among three land use types. In combination with SOC, CMI and soil physical properties, we argued that alfalfa grassland had the advantage to promote soil quality compared with arable land and forest land. This result shed light on the variations of soil properties influenced by land uses and the importance to conduct proper land use for the long-term sustainability of the saline-alkali reclamation region.

A study was conducted to determine whether NO3– stable isotopes (δ15N and δ18O), at natural abundance levels, could discriminate among NO3– sources from sites with different land uses at the basin scale. Water samples were collected from 24 sites in the Mississippi River Basin from five land-use categories: (1) large river basins (>34 590 km2) draining multiple land uses and smaller basins in which the predominant land use was (2) urban, (3) undeveloped, (4) crops, or (5) crops and livestock. Our data suggest that riverine nitrates from different land uses have overlapping but moderately distinct isotopic signatures. δ18O data were critical in showing abrupt changes in NO3– source with discharge. The isotopic values of large rivers resembled crop sites, sites with livestock tended to have δ15N values characteristic of manure, and urban sites tended to have high δ18O values characteristic of atmospheric nitrate.

To determine the soil infiltration characteristics of pine and acacia plantations, we used a double-ring infiltrometer in 15 different locations of up-hill, mid-hill and down-hill part in each kind of plantation from June to August, 2018. The spatial infiltration characteristics of the soil at three plots (with no tree, with acacia tree and with pine tree) was determined by dye tracer method. The factors having an impact to the infiltration process were also analyzed. The main findings include: (1) The soil infiltration rate under both pine and acacia plantation decreased over time and it was the highest in the bottom of the hill and the lowest in the middle of the hill. The infiltration rate and the total infiltrated water in one hour at the acacia plantation were higher than ones at the pine plantation. However, statistical significant difference was only found for stable infiltration rate between two plantations; (2) The area and the depth of infiltrated water were the highest at the plot without trees, smaller at the soil of acacia plot and smallest at the soil of pine plot. All spatial infiltration rates were within the findings of previous studies; (3) The result indicated that soil with high ground cover has high infiltration rate. Để xác định đặc điểm thấm nước của đất dưới rừng trồng Thông và Keo, vòng đôi đo tốc độ thấm đã được sử dụng để đo ở sườn trên, sườn giữa và sườn dưới (5 lần/ ví trí) cho mỗi loại hình rừng từ tháng 6-8/2018. Trong khi, thuốc nhuộm được sử dụng để kiểm tra đặc điểm thấm nước của đất theo không gian trên 3 ô (ô không có cây, ô trồng Keo và ô trồng Thông). Các yếu tố ảnh hưởng đến đặc điểm thấm nước cũng được phân tích. Kết quả chính thu được: (1) Tốc độ thấm ở cả hai loại rừng giảm dần theo thời gian và cao nhất ở sườn dưới,  nhỏ nhất ở sườn giữa. Cả tốc độ thấm và tổng lượng nước thấm trong một giờ của rừng keo đều cao hơn so với rừng Thông. Tuy nhiên, chỉ có tốc độ thấm ổn định là khác biệt có ý nghĩa thống kê; (2) Diện tích và độ sâu nước thấm xuống đất cao nhất ở ô không có cây, nhỏ hơn ở ô trồng Keo và nhỏ nhất ở ô trồng Thông; (3) Độ che phủ thực vật càng cao thì lượng nước thấm càng lớn.

The main cause of flooding and erosion that creates critical land in various regions in Indonesia is surface runoff. The surface runoff will occur if rainfall exceeds the capacity of soil water absorption (infiltration capacity). The soil management of each land use could improve the infiltration capacity. The water movement both on the surface and in the soil determines the water infiltration. This study predicts surface runoff based on the infiltration rate of various land uses and rainfall in the Ciliwung Watershed. A series of studies were performed in the upstream and middle areas of the watershed. Observations of soil properties, water movement, and rainfall were carried out in various dry land uses. The results showed that the soil's physical properties mostly determine the constant infiltration rate, which affected the water movement in the ground. The initial water content, the degree of saturation of the initial moisture content, and the soil's physical properties determine the time of constant infiltration rate. The value of constant rate infiltration and the time of its achievement define the amount of surface runoff that occurs.

Tea Bag Index

<p>Organic matter decomposition is an important process in global carbon cycling and its rate is altered by various factors. Changes in land use can have a significant effect on decomposition rates, with consequences on CO<sub>2</sub> emissions. The tea bag index (TBI) method is recognized as a simple and effective approach to investigate decomposition. Despite the fact that TBI has been globally applied, most research mainly focuses on soil microbiological aspects; the role of soil physical properties have earned less attention. Linking the soil physical properties to TBI can give us a broad understanding on how land use affects the soil microhabitat, and in turn influence carbon sequestration. Here, we measured the decomposition of green and rooibos tea in a transect from the east to west coast of Denmark across four land uses categorized into two groups (natural and cultivated). The natural group comprised forest and heath, and the cultivated group was composed of cereal and grass. Decomposition rate (<em>k</em>) and stabilization factor (<em>S</em>) were calculated after three months tea bag incubation. Soil physical properties including volumetric water content (VWC), air permeability and relative gas diffusivity (D<sub>p</sub>/D<sub>0</sub>) were measured at matric potential of –10 and –100 kPa. The cultivated land uses had higher <em>k</em> and <em>S</em> values compared to natural systems. The <em>S</em> was positively correlated with VWC and negatively correlated with D<sub>p</sub>/D<sub>0</sub> in natural systems while no relationship was found for cultivated land. However, there was a negative correlation of <em>k</em>-VWC and positive correlation of <em>k</em>-D<sub>p</sub>/D<sub>0</sub> in cultivated land, suggesting an impact of soil management and anthropogenic influence on litter decomposition and carbon sequestration.</p>

UB forest area has various land uses, namely the use of agroforestry land based on coffee and seasonal crops. This will result in various physical properties of the soil in each use, therefore this study aims to determine the physical properties of the soil in different land uses and obtain optimal land use in the UB Forest area. The research was conducted from June to September 2020 in Malang district. The study was conducted on land use of pine forest areas, pine agroforestry + coffee, pine agroforestry + seasonal crops, mahogany agroforestry + coffee and mahogany agroforestry + seasonal crops. The parameters observed included analyzing bulk density, particle density, porosity, available water, water content pF 2.5 and 4.2, hydraulic conductivity, aggregate stability, texture and organic-C. The results showed that land use in the forest area of UB affected the physical soil, namely bulk density, particle density, porosity, hydraulic conductivity, and aggregate stability. Other physical properties, namely soil texture in the UB area. Dominant forest with dusty and clayey clay textures while available water had no significant effect and pine land use is optimal use based on physical properties of soil density, density, aggregate stability and hydraulic conductivity and is supported by the value of organic-C. Soil organic matter in coffee pine land use also has the highest value than other land ranges from 3.44 to 5.07%

The present work had an objective to compare the stable infiltration rate obtained by infiltrometers with reduced dimensions and varied forms in different land uses. The infiltration tests were carried out in areas planted with cowpea, crotalaria, pigeon pea and millet, as crops previous corn planting, and managed with no-tillage, minimum tillage and conventional tillage and native forest area. In order to compare and analyze the results of the stable infiltration rates obtained between the alternative infiltrometers and the considered standard, the criteria involving the standard error of estimation (EPE), the standard error of estimation adjusted (EPEa), the standard error of estimation adjusted by origin (EPEao) and coefficients of adjustments of the linear equations with their respective determination coefficients (R2) were used. It was verified that the double-ring reduced, single-ring and double square infiltrometers provided a water saving of 57.06%, 66.19% and 38.54% respectively, relative to the standard. The alternative infiltrometers overestimated the stable infiltration rate in relation to the standard. The single-ring infiltrometer obtained a stable infiltration rate correction equation that showed results very close to the standard and the best statistical indices of stable infiltration rate results were obtained by the reduced double-ring infiltrometer.

Vineyard Soils

Vineyards are a 7000-year-old land-use tradition and both management and abandonment have result in altered soil properties. These have a great effect on water resources and soil services, and this inspired our investigation into the effects of land-use and land-use change on soils in the Modra wine-growing region in South-western Slovakia. Ten topsoil samples were taken at each of the seven research sites (n = 70) on granite parent material in cultivated and afforested vineyards and original forest soils. Laboratory analyses included determination of soil texture, organic carbon content, soil pH, and water repellency. This was supplemented by infiltration measurements under near-saturated conditions at the vineyard and afforested study sites. Studied soils have a low clay content and a high proportion of sand. The vineyard soils have significantly higher pH than the forest and afforested soils because the naturally acidic soils have been limed. The forest and afforested soils have similar properties, with higher organic carbon content. This makes them strongly to extremely water repellent and contrasts sharply with the wettability of cultivated vineyard soils. One afforested site, however, was less acidic and therefore was considered transitional between forest and vineyard soils. Our infiltration measurements established the influence of soil water repellency on the infiltration process, and our results highlighted that the infiltration rate in the vineyard soils was significantly higher than in afforested soils. The infiltration rate also gradually increased over time in afforested soils due to decreasing water repellency. Physically impossible negative sorptivity values in afforested soils were noted because of changes in water repellency during the infiltration process. Finally, we conclude that soil afforestation results in increased soil water repellency and a subsequent reduction in the infiltration rate at the matrix scale.
