The aim of this paper was to compare the rate of infiltration and cumulative infiltration in permanent grassland (PG) and in arable land over the course of the 2011 growing season. The measurement of water infiltration into soil was conducted via ponded infiltration method based on the use of two concentric cylinders in field conditions. Kostiakov equations were applied to evaluate the ponded infiltration. Based on field measurements, the dependence of infiltration rate (v) on time (t) was determined and also the dependence of cumulative infiltration (i) on time (t). In order to determine physical properties of soil and carry out a grain size analysis, intact soil samples of plough layer from the depths of 10, 20 and 30 cm were collected using Kopecký cylinders along with individual infiltration attempt in each measurement carried out on experimental plots. In order to assess the infiltration capacity of soil on experimental plots, four measurements were conducted, each with three repetitions. Infiltration attempts were held on May 12, June 28, August 24 and October 6, 2011. On average, a faster water infiltration into soil and a higher cumulative infiltration during the 2011 growing period were detected in arable land. The soil’s initial water content has proven to be the crucial factor affecting the rate of water infiltration into soil in case of PG; in case of arable land, it was bulk density indicating the soil’s compaction. The PG showed a more balanced course of infiltration rate and cumulative infiltration values during the growing season. Arable land is characterized by a greater dispersion of measured values between individual measurement dates.

Positive Effect

In the years 2008–2012, the infiltration capacity was monitored in the different sites, viz. on the arable land and permanent grassland. In the permanent grassland site the soil was characterised as Leptic Cambisol, loamy sand with the depth of the top layer 0.20 m while on the arable land, it was classified as Eutric Cambisol, sandy loam with the maximum depth of the topsoil humus horizon 0. 40 m. Experimental variants with different doses of incorporated compost were as follows: Variant 1 –without compost incorporation, Variant 2 – compost incorporated in the dose of 80 t.ha−1, Variant 3 – compost incorporated in the dose of 150 t.ha−1. It was found out within the study period that the application of the higher compost doses showed a positive effect on infiltration rate in both localities. In Variant 3, the highest values of the water infiltration were recorded. It can be concluded that the highest dose of compost (150 t.ha−1) improved and accelerated both the infiltration and water holding capacity of soil for a longer period. With the exception of the year 2009, increased values of water infiltration were recorded on experimental plots with arable land than with permanent grassland. It was found also that after five years have not been marked differences between variants. It follows that the regular supply of organic matter is necessary, preferably after three years.

Infiltration Capacity

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.

Weighing Lysimeter

Infiltration estimation is made by tests such as concentric cylinders, which are prone to errors, such as the lateral movement under the ring. Several possibilities have been developed over the last decades to compensate these errors, which are based on physical, electronic, and mathematical principles. In this research, two approaches are proposed to measure the water infiltration rate in a silty loam soil by means of the mass values of a lysimeter weighing under rainfall conditions and different moisture contents. Based on the fact that with the lysimeter it is possible to determine acting soil flows very precisely, then with the help of mass conservation and assuming a downward vertical movement, 12 rain events were analyzed. In addition, it was possible to monitor the behavior of soil moisture and to establish the content at field capacity from the values of the weighing lysimeter, from which both approach are based. The infiltration rate of these events showed a variable rate at the beginning of the rainfall until reaching a maximum, to descend to a stable or basic rate. This basic infiltration rate was 1.49 ± 0.36 mm/h, and this is because soils with fine textures have reported low infiltration capacity. Four empirical or semi-empirical models of infiltration were calibrated with the values obtained with our approaches, showing a better fit with the Horton’s model.

The Relationship ◽  
Over Time

The porosity of solid skeleton is changed under muddy water infiltration, and thus the permeability is also changed. A concentration of 30% muddy water compared with clear water, is experimented to simulate the movement of small particles. The relationship between solid skeleton permeability, porosity and time is obtained from experiments. The relationships among fraction void and permeability coefficient in such cases are presented. The relationship expressions are studied. Some novel laws are obtained as follows: because of the hindrance effect by the small particles, permeability coefficient decreases gradually over time, but clear water has no influence on the permeability coefficient; at the beginning, the porosity of solid skeleton decrease rapidly over time. Then it is stabilized latterly, they two are in monotone decreasing parabolic curve relationship; The relationship curve of cumulative infiltration capacity and time is a monotonically increasing curve which slope becomes smaller; the infiltration concentration fall first and rises later. The results provide a theoretical basis for muddy water infiltration.

Este trabalho teve como objetivo estudar o efeito da aplicação de diferentes lâminas de vinhaça na infiltração de água no solo e verificar a adequação dos modelos de Horton e Kostiakov-Lewis na estimativa da taxa de infiltração. Os tratamentos corresponderam à aplicação de cinco doses de vinhaça (0, 200, 250, 300 e 350 m3.ha-1). A aplicação de vinhaça propiciou uma redução da taxa de infiltração básica do respectivo solo em estudo, causando efeito negativo para essa característica, pois, eleva o risco de erosão do solo e majora a possibilidade do escoamento superficial. O modelo de Horton propiciou o melhor ajuste sobre os dados observados, e o modelo de Kostiakov-Lewis superestimou os valores da taxa de infiltração.   UNITERMOS: vinhaça, infiltração, solo.     DALRI, A.B.; CORTEZ, G.E.P.; RIUL, L.G.S.; ARAÚJO, J.A.C.; CRUZ, R.L. VINASSE APPLICATION INFLUENCE ON INFILTRATION CAPACITY OF SANDY LOAM SOIL     2 ABSTRACT   The objective of this study was to analyze effects in different depth in soil water infiltration and to verify the Horton and Kostiakov-Lewis models adequacy in infiltration rate estimate. The treatments were five doses of vinasse (0, 200, 250, 300 and 350 m³.ha¹). The vinasse application reduced the soil erosion risk increasing the possibility of runoff. The Horton model had the best adjustment on the observed data, and the Kostiakov-Lewis model overestimated the infiltration rate values.   KEYWORDS: vinasse, infiltration, soil.

Abstract Based on the Darcy's law and water balanceprinciple,some infiltration models have been proposed,but most of these models are not suitable for simulating infiltration into layered soils during unsteady rainfall. In this paper, a simple modelfor simulating water infiltration into the two-layer soil slopesduring unsteadyrainfallwasproposed, combined with the limit equilibrium methodto analyze the stability of thetwo-layer soil slope.The water infiltration rate of slopes depends on rainfall intensity and the actual infiltration capacity of soils. The proposedmodelhas been successfully applied to three cases (steady rainfall and homogeneous slope, unsteady rainfall and homogeneous slope,unsteady rainfall and two-layer soil slope), and it can be also combined with probabilistic methods to calculate the failure probability of slopes.Compared with the Richards model, the combination of the proposed model and the random field method can quickly obtain the failure probability of the slope.

Palau is an island in the Micronesia region of the western Pacific Ocean. The island receives heavy rainfall and has steep slopes, so 92% of the land is categorized within the most erodible rank, with a T factor of 5. A recent study reported that the water infiltration rate is proportional to the root mass of the crop soil; therefore, we attempted to evaluate the performance of root mass for preventing soil erosion. We covered parts of the land, with a slope of 15.4° (13.4°–17.3°), with weed control fabric to prevent the growth of grass and roots, then removed the fabric, cultivated the land, planted sweet potatoes, and compared the amount of soil erosion with other areas. Surprisingly, there was no erosion at all in the test plots, although there were 24 rainfall events that caused erosion. For the parameters of the Universal Soil Loss Equation (USLE) equation used in the present study, only the K factor was not actually measured. This means the K factor was larger than the actual value. Land at low risk of soil erosion and suitable for agriculture can be found by measuring K factor locally, even if the area is categorized as unsuitable.
