“…Similar results were measured by Agrawal et al (1987) in a sandy soil, with an increase in bulk density of 0.15 Mg m-3 (10.0-30-m depth) resulting in a decrease in infiltration rate of 42% and a decrease in hydraulic conductivity (0.10-0.30-m depth) of 56%.…”

“…When a sandy loam soil is tilled, the infiltration rate will be increased because of the lower bulk density but decreased because large-pore continuity will be disrupted, and the importance of these two factors will depend on the level of compaction of the soil (Kooistra et al, 1984). Infiltration rate of a sandy loam soil that has been compacted will usually be correlated with bulk density (Agrawal et al, 1987). Infiltration rate of a tilled soil may improve with time when cropped if tillage is eliminated (Parker and Jenny, 1945).…”

Settling and trafficking of a soil after tillage causes rapid changes in the soil physical condition until a new equilibrium is reached. In the soil studied, a Wasco (coarse-loamy, mixed, nonacid, thermic Typic Torriorthent) sandy loam, soil compaction reduces infiltration rates, which under grower conditions could result in inadequate infiltration of irrigation water to supply crop requirements. Our objective was to evaluate important management practices as they relate to changes in the infiltration rate of a sandy loam soil. Factors evaluated were traffic, tillage between crops, and the formation of channels by roots of perennial crops. Tillage between crops increased the infiltration rate during the first part of the season in trafficked soils but decreased or had no effect on nontrafficked soil. Alfalfa (Medicago sativa L.) increased the infiltration rate fourfold during a 2-yr period in a heavily compacted soil. An increase in bulk density from 1.6 to 1.8 Mg m-3 decreased infiltration rate 54% in the field. Hydraulic conductivity of undisturbed cores was at least seven times larger than that measured in columns of disturbed soil (same bulk density). This difference is believed to be the result of natural channels in the undisturbed soil that are destroyed when the soil is disturbed. Under controlled traffic, when surface seal is not a problem, tillage will not be necessary to obtain adequate infiltration rates except in the wheel paths.

“…The decreasing trend of infiltration during the irrigation events (first to third) was also noticeable, resulting from soil stabilization and water accumulation in the lower soil layer after each irrigation event (Agrawal et al, 1987; Al‐esawi et al, 2021). Proper estimations of infiltration under different surface irrigation schemes are especially important in the accurate estimation of irrigation application efficiency.…”

Surface irrigation models should take two‐dimensional infiltration of water in furrows into account for better representation and more accuracy. The Warrick–Lazarovitch infiltration model (W–L model) has been proposed to estimate the two‐dimensional infiltration of water in furrow irrigation. This model consists of several parameters, including γ as an empirical parameter, which is often obtained through calibration of the model. This study aimed to evaluate the W–L model performance in determining the cumulative and lateral infiltrations under conventional furrow irrigation (CFI) and alternate furrow irrigation (AFI) schemes and two different initial and boundary conditions. The results indicate that the W–L model adequately estimated the cumulative and lateral infiltration, and the two‐dimensional infiltration was estimated with less error than the lateral infiltration. In both irrigation schemes, for an increased surface boundary head from 5 to 10 cm and for a reduced initial water content from 0.21 to 0.16 cm3/cm3, the value of γ would increase. Generally, γ values in AFI were greater than those in CFI. The W–L model estimated the two‐dimensional infiltration with more accuracy than the relative lateral infiltration for both CFI and AFI. Proper representation of infiltration is important in both irrigation management and in tracing footprints of chemicals used in agriculture.

“…Kooistra, Bouma, Boersma and Jager (1984)) explain that the level of compaction of a tilled sandy loam soil affects its overall infiltration rate. This was summed up by Agrawal, Jhorar, Dhankar and Raj (1987) when they said that the infiltration rate of a sandy loam soil that has been compacted will usually be correlated with bulk density. Meek, Rechel, Carter, DeTae and Urie (1992) investigated effects of traffic, tillage and plant root on infiltration rate of a sandy loam soil, and found that an increase in bulk density of the soil from 1.6 to 1.8Mgm 3 decreased infiltration rate by 54%.…”

In this paper the compaction level of a sandy-loam soil in a humid tropical climate, most suited for maize cultivation for high productivity was investigated. This involved studying the yield of maize under varying compaction conditions of the soil. Five experimental plots of land at the teaching and research farm of the Rivers State University of Science and Technology, Port Harcourt, Nigeria were used for the exercise. Four of the plots were tilled, while one was left in its original state. Three of the four tilled plots were compacted by wheel traffic; and the compaction values of all the five plots, measured by their bulk densities are 1.17g/cm 3 , 1.20g/cm 3 , 1.23g/cm 3 , 1.28g/cm 3 , and 1.35g/cm 3 . The plot that was left in its original untilled and un-compacted state was used as the control plot. Irrigation of the field, weed and pest controls were done uniformly for all the plots. The maize plant was cultivated between October and February and its growth and yield estimated in terms of plant height, leaf area, number of plants to reach maturity, and quantum of dry matter and grain obtained. Results of early shoot emergence showed that plots with lower bulk densities had higher percentage emergence than the ones with higher bulk densities. Furthermore, it was found that the maize yield was significantly affected by the soil bulk density at P<0.05. A compaction value of 1.31g/cm 3 is determined as optimal for maize cultivation in a sandy-loam soil in a humid tropical environment.
