Cumulative Infiltration

Experiments were conducted in a soil laboratory using transparent columns (5 and 40 cm in diameter and length, respectively) to evaluate the effects of water quality (i.e., fresh or saline water) with the addition of biochar on soil moisture characteristics. Soil and biochar were gently combined and added into the top 10 cm of each column at a rate of 2%, 4%, 6%, and 8% (w/w). The results show a decrease in cumulative evaporation by 29.27%, 16.47%, 14.17%, and 14.61% with freshwater, and by 21.24%, 12.22%, 21.08%, and 12.67% with saline water for B1, B2, B3, and B4, respectively, compared with unamended soil (B1, B2, B3 and B4 represent the treatments with the biochar rate of 2, 4, 6, and 8%, respectively). Cumulative infiltration was reduced by 34.38%, 43.37%, 58.89%, and 57.07% with freshwater, and by 30.18%, 44.38%, 54.44%, and 49.11% with saline water for B1, B2, B3, and B4, respectively. The infiltration rate was reduced by 32.73%, 42.17%, 57.82%, and 56.85% with freshwater, and 42.09%, 54.6%1, 62.68%, and 58.41% with saline water for T1, T2, T3, and T4, respectively, compared with the control. The saturated hydraulic conductivity of B1 decreased significantly by 92.8% and 67.72% with fresh and saline water, respectively. Biochar, as a soil conditioner, could be used in arid conditions with fresh and saline water to enhance the hydrological properties of sandy soils.

Abstract Climate change and urbanization increase the pressure on combined sewer systems in urban areas resulting in elevated combined sewer overflows, degraded water quality in receiving waters, and changing stream flows. Permeable surfaces offer infiltration potential, which can contribute to alleviate the runoff to combined sewer systems. The variation in urban soil characteristics and the initial moisture conditions before a rainfall event are important factors affecting the infiltration process and consequently runoff characteristics. In this study, the urban hydrological models SWMM and STORM are used to evaluate the Green-Ampt, Horton, and Holtan infiltration methods for three urban sandy soils. A sensitivity analysis was carried out on a set of key parameter values. In addition, long-term simulations were conducted to evaluate the ability to account for initial soil moisture content. The results showed that the Holtan method's ability to account for both available storage capacity and maximum infiltration rate, as well as evapotranspiration in the regeneration of infiltration capacity, gave the best result with regards to runoff behaviour, especially for long-term simulations. Furthermore, the results from the urban sandy soils with different infiltration rate at saturation, together with a high sensitivity to the degree of sensitivity for maximum infiltration rate under dry conditions and minimum infiltration rate under wet conditions, indicate that field measurements of infiltration rate should be carried out at saturation for these soils.

HighlightsConservation practices (straw mulch, manure, peanut-orange intercrop) reduced soil and water loss vs. tillage.Reductions in soil loss were greatest under high rainfall intensity or low soil moisture.Measured interrill erodibility was relatively high in dry run tests and decreased with the final infiltration rate.ABSTRACT.Tillage practices have been adopted extensively to control runoff and soil loss from croplands. To quantify the effects of tillage practices on erosion processes in interrill areas, microplot rainfall simulation experiments were conducted in peanut fields with five tillage practices in the red soil region of China. The results showed that conservation tillage practices, including straw mulch cover (PC), manure fertilizer (PM), and peanut-orange intercropping (PO), could significantly conserve water and reduce soil loss rates by more than 50% compared with traditional furrow (PF) and peanut-radish rotation (PR) treatments. The variations in the hydrologic and soil loss indexes among the treatments were larger in the dry run tests than in the wet run tests. Accordingly, the efficiencies of the conservation practices in reducing soil loss were reflected mainly under a high rainfall intensity or low soil moisture in this study. Additionally, the runoff generation indexes were significantly correlated with the soil loss rate in all five treatments. The measured interrill erodibility was highest in the PR treatment (944,124 kg s-1 m-4) and lowest in the PO and PM treatments (571,797 and 584,238 kg s-1 m-4, respectively), as the organic matter content and aggregate stability were relatively high in the two conservation treatments. Influenced by the dynamics of loose materials and possible surface sealing, the interrill erodibility was relatively high and decreased with the final infiltration rate when measured under the dry run conditions. These results could guide cropland soil management and improve process-based erosion models.

Guelph Permeameter

The vineyards of Ruwer-Mosel valley (Germany) cultivated on steep slopes showed a high spatial and temporal variability of hydrological dynamics. Forty two experiments were carried out using a Guelph permeameter in old and young vines to measure the infiltration rates, the hydraulic conductivity and the soil matrix flux potential. The essays were performed before (spring-summer) and after (autumn) the harvest with dry soil conditions and without soil tillage signals, and with humid soil conditions, signals of soil farming (wheel traffic and footprints) and a decrease of organic matter, respectively. In general, the results of the young vineyards were higher than the values of the old vineyards. Furthermore, all the rates increased after the harvest. For the young vineyards, the most elevated values were registered on the middle slope (398.5 mm h-1 infiltration rate, 89.2 mm h-1 hydraulic conductivity and 62.8 mm2 h-1 soil matrix flux potential). For its part, a decrease of the infiltration from the upper slope to the foot slope was observed (from 42.5 to 16.8 mm h-1). Hydraulic conductivity and soil matrix flux potential showed the same hydro-dynamic: from 13.2 to 5.4 mm h-1 and from 5.5 to 2.5 mm2 h-1, respectively. Finally, it was observed that the most correlated factor with these hydrological processes was the soil moisture content and the soil tillage practices.

Abstract Soil provides suitable media for plant growth and development during the whole crop life cycle. The agronomic management practices can improve the soil fertility and crop productivity on sustainable basis. To explore the effects of some agromanagement practices on the spring maize, an experiment was conducted at the Agronomic Research Area, University of Agriculture, Faisalabad, Pakistan, during spring season 2010 and 2011, using randomized complete block design with split block design arrangements. The experiment comprised of four tillage treatments viz: zero tillage (T1), minimum tillage (T2), conventional tillage (T3) and deep tillage (T4) in the main plots, while the four mulch treatments i.e. control (M1), black plastic mulch (M2), wheat straw mulch 10 Mg ha-1 (M3) and grass mulch 10 Mg ha-1 (M4) in the sub plots. Irrigation was provided according to crop requirement and herbicides were applied to control the weeds. All the tillage practices significantly affected (p<0.05) the different soil physical properties i.e. soil bulk density, soil total porosity, water infiltration rate and root penetration resistance. Deep tillage practice and black plastic mulch significantly increased the grain yield (m-2) of spring maize than the zero tillage, minimum tillage, conventional tillage, no mulch, wheat straw mulch and rice straw mulch in both years of study. The two years field results suggested that the mulches improved soil aeration and water infiltration rate, lower the soil bulk density and root penetration resistance than the control treatments.

Water Repellence

Rapid methods for measuring the severity of water repellence were assessed in 101 sandy soils from South Australia. The molarity of aqueous ethanol droplets that were absorbed by the soil in 10 s, the time of water droplet entry and the infiltration rate of water from a small ring infiltrometer were compared with the soil-water contact angle and with each other. Relationships between the tests were fitted by linear, quadratic and cubic regressions and were highly significant (100r2 = 70-92). The relationships were used to provide ratings of repellence normally found in the field. Factors which affect the measurement of repellence in the field were examined. Abrasion of sand particles during light sieving had only small effects on repellence, but more vigorous abrasion through rotational movement of the sand reduced repellence markedly. Repellence decreased with increasing temperature. Simple corrections for temperature were calculated and presented in figures as isorating charts. The moisture content of the soil had large and variable effects on the repellence tests. At moisture contents between oven and air dry (pF 5.6) there was little effect on the ethanol droplet or infiltration rate tests. Measurements by the ethanol droplet test were not reliable at moisture contents greater than air dry. At soil water contents between air dry and wilting point (pF 4.2), the infiltration rate of water was either unchanged or decreased in different soils. It then increased rapidly and reached a constant value near field capacity (pF 2.5). The infiltration rate also decreased when the time of moistening of the soil before the tests were made was extended from 20 to 168 h. It is recommended that repellence tests be made on oven- or air-dry soils. The aqueous ethanol and water droplet, and infiltration rate of water tests are all suitable for rapid assessment of repellence in the field.

&lt;p&gt;The soil hydraulic properties controlling infiltration are dynamic depending on interrelated factors such as soil texture and structure, climate (rainfall intensity), land use, vegetation cover and plant root systems. These physical and biological factors directly influence the size and geometry of the conductive pores, and therefore the bulk density, soil structure and finally water infiltration at surface. In the Sahelian zone, the slightest modification of the physical properties of the soil has severe consequences on the soil properties and thus on hydrological processes. It is therefore essential to improve knowledge on the spatial distribution of the hydraulic behavior of soils for optimization of agricultural uses.&lt;/p&gt;&lt;p&gt;We used the BEST method (Beerkan Estimation of Soil Transfer parameters) on a toposequence of the Senegalese groundnut basin (Fatick region) in the Faidherbia-Flux observatory[1] where the average rainfall is 590 mm/yr. The studied toposequence (400 m long) is representative of a common agroforestry zone with annual cultivation of millet and peanuts and a sparse density of Faidherbia albida. The slope is low (1%) with small lowland areas made up of sandy soil with more clay (clay soil), while the glacis is represented by more or less compacted sand. The infiltrometry measurements were made with the automatic single-ring infiltrometer developed by Di Prima et al. (2016), used here for the first time in West Africa. The explicative variables tested are the type of soils, including: clay soils under tree (CLUT) and outside tree (CLOT), sandy soils under tree (SSUT) and outside trees (SSOT), and cattle trampled soils outside trees (TSOT) particularly compacted and largely present in the study area. BEST algorithms were applied to the experimental data to determine the hydraulic properties of the soils of the different variables and to draw water retention and hydraulic conductivity curves.&lt;/p&gt;&lt;p&gt;There are significant differences in infiltration rates between the sampled zones and in relation with the studied factors. The highest infiltration rate is found on sandy soils under tree (SSUT) with an average infiltration rate of 14.0 mm/min, followed by SSOT with 11.6 mm/min. Then the clay soils CLUT and CLOT are characterized by similar lower hydraulic responses with average infiltration rates of 6.9 mm/min and 6.2 mm/min, respectively. The average infiltration rate is the lowest on the compacted sandy soils TSOT, with only 5.4 mm/min. The study of the variability of the infiltration rates measured by class of variable shows a large variability for CLOT, CLUT and SSUT (decreasing order of variability). These results are in agreement with the measured values of dry soil bulk density. The high infiltration rates in the clay soils outside and under trees can be explained by the higher content of organic matter observed on the sampling, and probably by the existence of preferential flow activated by the macropores particularly present on clay soils (CLOT and CLUT) and on sandy soils under tree (SSUT).&lt;/p&gt;&lt;p&gt;Di Prima, S., et al., 2016.
