ABSTRACTSoil types have different infiltration rates and vary depending on the characteristics of the soil, how the infiltration relationship occurs with dry water content and saturated water content, infiltration relationship with the soil after being compacted and before compacted and how the infiltration rate of the two types of relationship and how infiltration water that happened. Soil tests are carried out in the laboratory, soil water content before and after the soil has been solidified, changes in the time of infiltration capacity with the Horton equation, rain hydrograph for overall infiltration analysis, including cumulative infiltration and runoff rates.Soils experience porosity filling not as great as in normal soil conditions, normal soil conditions changes in water content reaches 5.22 mm/hour while in soil conditions that experience changes in water content compaction at 30 minutes by 0.14 mm/hour and experiences a constant rate in the 40th minute at a rate of 0.20 mm/hour, so there is a difference in water content of 5.08 mm/hour between normal soil and soil after solidification, due to compacting it causes runoff of 8.92 mm/hour, normal soil with runoff of 3.78 mm/hour.Keyword :  Infiltration, soil physical properties, runoff.

A 2-year field trial determined the influence of applying spent mushroom substrate (SMS) on soil physical properties and the growth of 4 consecutive vegetable crops (sweetcorn, cabbage, potato, cabbage). Treatments comprised 0, 20, 40, and 80 t/ha of moist SMS, both with and without inorganic fertiliser, applied to each crop, giving a range of SMS rates up to 320 t/ha. SMS improved the environment for plant root growth by decreasing soil bulk density (by 0· 05-0·25 g/cm 3 at 100 mm depth), increasing aggregate stability (by 13-16%), reducing clod and surface crust formation (by 16-31 and 18-94%, respectively), increasing the infiltration rate (by 130-207 mm/h), increasing the water content of the soil (by 0-7% w/w), and reducing diurnal temperature changes. Some of these changes were not evident until repeated applications of 80 t/ha SMS had been made. Soil physical properties were related to crop yield, and soil physical properties’ principal components were related to crop principal components using regression analysis (r2 of 0·20-0·60 and 0·16-0·54, respectively). The soil physical properties that had the most influence on plant growth were specific to each crop and included bulk density, water content, surface crust cover, infiltration rate, and aggregate size distribution. Soil physical properties had a large influence on the potato yield irrespective of fertiliser use and on both cabbage crop yields when fertiliser was not used, but not on the sweetcorn yield (the first crop to be grown). The effect of changing soil physical properties on plant growth was most apparent when fertiliser was not used. This was because the improved physical properties increased plant yield (at least in part) because of increased plant nutrient uptake.

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.

The study was conducted to investigate if erosion is a major problem and to identify the effect of erosion on some physical properties on selected farmlands on four farms in Gidan kwano. It was done by observation, interview, and questionnaire and soil sample analysis. The infiltration rate, bulk density, porosity, organic matter content, particle size and aggregate stability were determined for all the sample location. The erosion fields results were compared with the results of the non-eroded fields. The results showed that farming was done with simple method and mechanized equipment when available and erosion was considered a major problem in all the farms. The results revealed that bulk density values ranged between 1.475gcm-3and 1.606gcm-3, cumulative infiltration rate fluctuated between 29.75cm/hr and 37.48cm/hr, porosity ranged between 36.49% and 44.34%, organic matter content fluctuated between 0.29% and 0.73% and aggregate stability ranged between 58.00% and 67.60% for the erosion field. The results also revealed that bulk density fluctuated between 1.458gcm-3and 1.544gcm-3, cumulative infiltration rate ranged between 32.19 cm/hr and 40.48cm/hr, porosity fluctuated between 41.73% and 44.98%, organic matter content ranged between 0.30% and 1.09% and aggregate stability ranged between 63.97% and 68.93% for the non-eroded field. From the results, it provides evidence that the effects of erosion on the physical properties were increased bulk density, decreased infiltration rate, organic matter content, porosity, aggregate stability and percentage sand, silt and clay content. Statistical analysis proved that the results were significant (p<0.05) except for the bulk density and porosity which could be attributed to the swelling and compaction characteristics of the soils.

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.

Infiltration study is very crucial in modelling water requirement of crops during their growth season. Infiltration rate measurements were carried out on dryland areas of Sokoto, Sudan savanna ecological zone of Nigeria; using the double ring infiltrometer. Disturbed and undisturbed soil samples were used to determine some physical characteristics (Texture, Saturated hydraulic Conductivity, particle density, bulk density, porosity and organic matter) of the soil. The results showed that the cumulative infiltration predicted by Horton infiltration model was very close to the field measurements for all the spots from the average values (3.35, 2.83 and 1.71 cm/min) and predicted rates (2.37,2.34 and 1.54 cm/min) with coefficient of determination (R2) close to unity (0.98, 0.97, 0.97) for the three spots. The study showed that the Horton infiltration model can be applied to estimate infiltration characteristics of some soils in Sudan Savanna of Nigeria.

Controlled Traffic

Wheel traffic can lead to compaction and degradation of soil physical properties. This study, as part of a study of controlled traffic farming, assessed the impact of compaction from wheel traffic on soil that had not been trafficked for 5 years. A tractor of 40 kN rear axle weight was used to apply traffic at varying wheelslip on a clay soil with varying residue cover to simulate effects of traffic typical of grain production operations in the northern Australian grain belt. A rainfall simulator was used to determine infiltration characteristics. Wheel traffic significantly reduced time to ponding, steady infiltration rate, and total infiltration compared with non-wheeled soil, with or without residue cover. Non-wheeled soil had 4—5 times greater steady infiltration rate than wheeled soil, irrespective of residue cover. Wheelslip greater than 10% further reduced steady infiltration rate and total infiltration compared with that measured for self-propulsion wheeling (3% wheelslip) under residue-protected conditions. Where there was no compaction from wheel traffic, residue cover had a greater effect on infiltration capacity, with steady infiltration rate increasing proportionally with residue cover (R 2 = 0.98). Residue cover, however, had much less effect on inf iltration when wheeling was imposed. These results demonstrated that the infiltration rate for the non-wheeled soil under a controlled traffic zero-till system was similar to that of virgin soil. However, when the soil was wheeled by a medium tractor wheel, infiltration rate was reduced to that of long-term cropped soil. These results suggest that wheel traffic, rather than tillage and cropping, might be the major factor governing infiltration. The exclusion of wheel traffic under a controlled traffic farming system, combined with conservation tillage, provides a way to enhance the sustainability of cropping this soil for improved infiltration, increased plant-available water, and reduced runoff-driven soil erosion.
