“…However, these same four correlations were not significant in any other year tesced. Similar results have been reported by De Boodt et al ( 2), who have found that significant correlations of soil structure with crop yield often depend on weather conditions.…”

“…Other parameters that have been developed to express aggregate size distribution in terms of one or two numbers are the weighted mean diameter and standard deviation (Puri & Puri, 1939) and the coefficient of aggregation (Retzer & Russell, 1941). De Boodt et al (1961 found that change in mean weight diameter when dry soil samples are wetted was correlated with crop yields.…”

“…Observations of Bryant et al (1948) and data by Strickling (1951), Schaller and Stockinger (1953), and Panabokke and Quirk (1957) all indicate that results from simple one-and two-sieve methods of determining aggregate stability are closely correlated with results using several size ranges of aggregates and sieves, when expressed in terms of mean weight diameters. Consequently, a single size range of aggregates is employed in preference to more time-consuming methods such that of De Boodt et al, (1961), using several size ranges of aggregates and sieves. Kemper and Koch (1966) found a slight tendency for aggregate stability to decrease when the temperature of water used to wet and sieve the samples was increased from 20 to 30 "C. Consequently, the temperature of the water should be maintained within the range of 22 to 25 "C, Appreciable salt in the water can cause changes in the ionic status and stability of the soils; therefore, it is suggested that the salt content of the water be low enough so that the electrical conductivity is <0.01 dS ml «0.01 mho cm "), On the other hand, low electrolyte in the water increases swelling pressures between particles which can lower stabilities of sodic soils (e.g., Shainberg et aI., 1981).…”

“…Benoit, et al (1962) found significant correlations between maize yield and the WSA of a sandy-loam soil only in one out of four years, and attributed this result to adverse weather conditions in that year. De Boodt, et al (1961) concluded that significant correlations of soil structure with crop yield are weather-dependent. In contrast, Strickland (1951) and Morachan, et al (1972) observed no correlations between properties of silt-loam soils and corn yield.…”

Soil erosion and runoff were monitored from 1988 to 1990 on a Miamian soil (Typic Hapludalf) of 5‐6 per cent slope using field runoff plots. Four treatments were studied: (i) disk‐plough up and down the slope to 0.3 m depth (DP); (ii) disk‐plough up and down the slope followed by a protective netting (PN); (iii) uncultivated fallow without any vegetation followed by surface soil removal (R); (iv) uncultivated fallow with natural vegetation followed by ploughing (F). Mean annual runoff losses were 6, 114 and 128 mm, or 4, 20 and 18 per cent of the rainfall, and mean annual soil losses were 1.2, 85.0 and 64.0 Mg ha−1 in 1988, 1989 and 1990, respectively. Mean runoff amounts were 26, 69, 116 and 118mm and mean annual soil losses were 0.4, 23.2, 58.6 and 118 Mg ha−1 for the F, PN, DP and R treatments, respectively. In comparison with DP, PN decreased annual runoff by 40.3 per cent and annual soil loss by 79.5 per cent. The high mean soil loss for the R treatment was due to erosion following soil removal. An additional 2920 Mg ha−1 of surface soil was removed from the R treatment in May 1990. The F treatment reduced runoff by 78, 77 and 62 per cent and reduced soil loss by 99.7, 99.4 and 98.4 per cent compared with the R, DP and PN treatments, respectively. Mean losses of K, Ca, Mg and P were 1.3, 4, 1 and 01 kg ha−1, respectively for F, 3, 16, 5 and 0.3kg ha−1, respectively, for PN, 5, 31, 1 and 0.6kg ha−1, respectively, for DP, and 3, 32, 12 and 0.4 kg ha−1, respectively, for R. Soil and nutrient losses for each treatment were in the order R > DP > PN > F. The soil organic carbon (SOC) content was significantly affected by soil erosion and management treatments, and ranged from 0.98 per cent for the R treatment to 2.3 per cent for the F treatment. Soil surface removal for the R treatment in 1990 reduced water‐stable aggregates (WSA) by 9.0 per cent, SOC by 0.6 per cent, and clay content of the uppermost 0‐50 mm depth by about 7.0 per cent. Mean total porosity (ft) ranged from 0.43 for the F to 0.52 for the DP treatment. Cumulative infiltration for 3h ranged from 13 cm for R to 34cm for PN, with corresponding infiltration rates of 4 cm h−1 and 13 cm h−1, respectively. Regardless of the treatment, there were also temporal changes in soil properties. In comparison with 1988, measurements made in 1990 showed a significant decrease in WSA of 21.3 per cent, an increase in clay content of 2.8 per cent, and a decrease in SOC of 0.39 per cent. Runoff and soil losses were significantly correlated with the mean weight diameter (MWD), SOC, bulk density (pb) and available water capacity (AWC). Plant height measured 8 weeks after planting (WAP) for the R treatment was reduced by 33.3 per cent, 33.0 per cent and 29.0 per cent compared withh DP, PN and F, respectively. Nitrogen uptake by maize plants (Zea mays L.) 10 WAP for the R treatment was lower by 15 per cent, 8 per cent, and 6 per cent compared with the DP, PN and F treatments, respectively, while P uptake was lower by 33 per cent, 32 per cent and 29 per cent, respe...
