The data for phosphate retention of the eighteen surface soil samples in a wide range of phosphate concentration (up to 100 μmP/g soil) were all found to be in close agreement with Langmuir, Freundlich and Temkin equations. Their correlation coefficients (r) were mostly over 0.97. Among these equations the Langmuir adsorption isotherm seemed to be the best fitting model. The great differences of their phosphate retention capacity were evidenced by the variations both in their adsorption maxima (M) and their...

The data for phosphate retention of the eighteen surface soil samples in a wide range of phosphate concentration (up to 100 μmP/g soil) were all found to be in close agreement with Langmuir, Freundlich and Temkin equations. Their correlation coefficients (r) were mostly over 0.97. Among these equations the Langmuir adsorption isotherm seemed to be the best fitting model. The great differences of their phosphate retention capacity were evidenced by the variations both in their adsorption maxima (M) and their bonding energy parameters (K). Thus, M varied from around 300 μg P/g soil (Psammaquent, 504 and Loessial soil 498) to 1500 μg P/g (Lateritic sail, 497). For the soil of volcanic ash orgin, it even ran up as high as 5000 μg P/g. In terms of percentage of phosphate added (100 μm P/g soil), the adsorption rates by these soils correspond to about 10%, 47% and 95% of the added phosphate respectively.Among various physical and chemical properties of the soils studied, the contents of clay, as well as the amorphous and crystalline free iron and aluminum oxides were found to be all correlated with the phosphate retention capacity. In spite of the diversity of the soil samples, the specific surface area of the soil was found to be the most relevant single attribute which shows the best correlation with the phosphate retention capacity.Cultivation practices, fertilizer applications and use of organic refuses exerted some influences on soil phosphatic retention properties. Seasonal flooding of soil by conver. ting upland red earth into irrigated rice field is particularly effective in lowering the M and K values of their phosphate adsorption isotherms.

18个供试土样,在较宽的磷浓度范围内(0—100μmP/g土),它们的吸磷特征与Langmuir,Freundli-ch和Temkin方程式都有很好的相关性(r值大多在0.97以上),尤以Langmuir方程式最佳。各供试土样吸磷能力差异很大,其最大M从大约300μg P/g土(黑垆土)到1500/μg P/g土(砖红壤),火山灰土则高达5000μg P/g土。当加入100μm P/g土时,上述各土壤吸磷量分别占加入磷量的10%,47%和95%左右。土壤粘粒含量以及无定形和结晶态游离氧化铁铝含量均各与M显著相关。土粒的比面可作为单一的指标,它能较妥切而综合地反映土壤的吸磷能力。有机质对土壤吸磷能力的影响是复杂的,它可以增加或减少M值。耕作施肥特别是红壤旱改水多年后,显著地降低了原土壤的M和K值。砂潮新成土上不同施肥处理小区的吸磷等温线表明,土壤中新增加的粗有机物质对磷的吸持作用多发生在磷浓度较高的范围内,它是以吸附量高而吸附结合能低为特征的。

作者用模糊集隶属度与模糊集贴近度的方法对浙江省海涂土壤作定量分类。结果表明:该方法没有发生错判,方法本身具有的可靠性好,同时应用这种方法还发现了原土壤分类中有误的一些剖面。与多元统计中的判别分析比较,模糊集隶属度法更为简便,也更符合土壤分类需要。因此文中认为可用模糊集隶属度与模糊集贴近度来定量判断土壤的归属及表示土壤类型之间的相互关系。
