“…Secondly, because of the lower organic matter and clay content, the water retention capacities of the land-use plots may be lower. The signi®cant in¯uences which organic matter and clay exert on soil water holding capacities have for long been well recognized (Jamison and Kroth, 1958;Abrol, et al, 1968;Lal, 1978;Gbadegesin, 1989). Similarly with the breaking-up of soil structure as the land-use plots are disturbed by cultivation, harvesting and grazing practices, there is a tendency for water retention capacity of the soils to be reduced (Jamison, 1953).…”

“…This curve is constructed using experimental measurements and allows us to determine values for the main properties of soil water retention: gravimetric moisture at field capacity, gravimetric moisture at the permanent wilting point, and available water-retention capacity (amount of water that can be used by plants). The main properties that influence soil moisture characteristic curves are the distribution of the textural fractions, structure, organic carbon content, bulk density, and, in a semi-arid environment, the calcium carbonate content (Abrol, Khosla, and Bhumbla 1968;Hollis, Jones, and Palmer 1977;Khodaverdiloo et al 2011;Kironchi, Kinyali, and Mbuvi 1995;Rawls et al 2003;Reeve, Smith, and Thomasson 1973). These properties can be modified, as indicated previously, by the change in soil use and a limestone amendment (as one of the most significant tasks of management of acidic soils).…”

The influence of sugar foam amendment on the moisture-retention properties of three profiles of an acidic vineyard soil in Retuerta del Bullaque (Ciudad Real, Spain) has been studied. The values obtained for the surface horizons of modified soils and the original soil (under natural vegetation) were compared, as were those for the surface and subsurface horizons of the liming profiles. The water-retention curves (drying curve) were determined in triplicate on the sieved soil with Richards plates and the field capacity (FC), permanent wilting point (PWP), and available water-retention capacity (AWRC) were calculated. In the original soil FC, PWP, and AWRC values were greater than the average values for the amended soils (36.5 percent, 15.1 percent, and 21.5 percent versus 23.5 percent, 10.35 percent, and 13.1 percent, respectively). Comparison of the surface horizons and the subsurface horizons of the three profiles showed that the values for the AWRC were greater in the former (13.1 percent, 12.5 percent, and 14 percent for P1, P2, and P3, respectively) than in the latter (11.9 percent, 9 percent, and 8.6 percent for P1, P2, and P3, respectively), although FC and PWP were lower in A horizons than in B horizons.

“…For example, the report on benchmark (map scale = 1:20 million) soils of India (Murthy et al, 1982) contains limited θ FC and θ PWP data, but data on θ(h) and saturated hydraulic conductivity (K s ) are lacking. Consequently, most of the reported PTFs from India (Abrol et al, 1968;Bhavanarayana et al, 1986;Rao et al,1988;Singh et al,1992;Singh, 2000;Santra, 2001;Saikia and Singh, 2003) are developed from limited datasets and narrow ranges of input parameters. In addition, such PTFs are primarily set up for point PTFs for θ FC , θ PWP , and K s .…”
