Abstract Degradation by wind erosion is detrimental to both soil and land quality in arid regions. This study was conducted to investigate the effectiveness of some organic amendment - poultry manure (PM), farmyard manure (FYM) and rice husk (RH) and were applied on the sandy soil surface at 1 and 3 cm thickness and control (no treatment; C) to make clear the sand particles stabilization. Total soil nitrogen, organic carbon (OC), and pH in the PM and FYM treatments exceeded those in the RH treatment. Soil hardness in the PM compost was 6.7, 1.4, and 2.7 times the mean determined in the control, FYM and RH, respectively, whereas CaCO3 in the PM treatment was 56 and 69% higher than the levels in FYM and RH, respectively. Soil hardness varied in the order of PM 3 cm > PM 1 cm > FYM 1 cm > FYM 3 cm > RH 1 cm > RH 3 cm > C. The erodible fraction (0.85–1.0 mm) decreased linearly with increase in soil hardness (R2 > 0.9), OC, CaCO3. Farmyard manure and PM composts decreased the erodible fractions by up to 5 and 15%, respectively. Surface application of PM compost is an effectively stabilized the sand particles during this study.

有机改良剂和施用厚度对沙土和沙土性质的影响
摘要 风蚀退化对干旱地区的土壤和土地质量都是不利的。本研究旨在调查一些有机改良剂 - 家禽粪便 (PM)、农家肥 (FYM) 和稻壳 (RH) 的有效性,并以 1 厘米和 3 厘米的厚度施用于沙质土壤表面和对照(未处理; c) 使砂粒稳定化。PM 和 FYM 处理的土壤总氮、有机碳 (OC) 和 pH 值超过了 RH 处理。PM 堆肥中的土壤硬度分别是对照、FYM 和 RH 中确定的平均值的 6.7、1.4 和 2.7 倍,而 PM 处理中的 CaCO3 分别比 FYM 和 RH 中的水平高 56% 和 69%。土壤硬度变化顺序为 PM 3 cm > PM 1 cm > FYM 1 cm > FYM 3 cm > RH 1 cm > RH 3 cm > C。可侵蚀部分(0.85-1.0 mm)随着土壤硬度(R2 > 0.9)、OC、CaCO3 的增加而线性下降。农家肥和 PM 堆肥分别减少了 5% 和 15% 的可侵蚀部分。在本研究中,PM 堆肥的表面应用有效地稳定了沙粒。
