Abstract

The area studied Taza-Taounate is a vast mountain range in north-central Morocco, characterized by a variation in bio-geographical factors that encourage a vibrant and diversified vegetation cover with a remarkable rate of endemism compared to Moroccan flora. Our work involves the physicochemical analysis of soils at seven stations in the study area. Three surface soil samples (0-15 cm) were collected and analyzed for physical and chemical parameters using standard laboratory techniques at each station. The results showed the clay fraction's dominance in S2 and S3 and the silt fraction in stations S1, S4, S5, S6, and S7. The studied soils have low levels of organic carbon (0.97% to 2.29%), high levels of CaCO3 (10.1% to 24.9%), and neutral and slightly alkaline pH (7.01to 7.81). The most dominant element in all stations is calcium exchangeable, with values ranging from 51.52 to 74.91 cmol+/kg. The other exchangeable basic cations (Mg, Na, K) have relatively low levels. CEC values vary between 36.12 and 81.13 cmol+/kg, indicating that our soil type is heavy to organic.

摩洛哥Taza - Taounate不同地区土壤资源的理化评价

所研究的Taza-Taounate地区是摩洛哥中北部的一个巨大山脉，其特点是生物地理因素的变化，促进了充满活力和多样化的植被覆盖，与摩洛哥植物区系相比，其特有率显着。我们的工作包括对研究区七个站点的土壤进行理化分析。在每个站点收集3个表层土壤样本(0-15 cm)，并使用标准实验室技术分析其物理和化学参数。结果表明:S2、S3站以粘土组分为主，S1、S4、S5、S6、S7站以粉砂组分为主。土壤有机碳含量低(0.97% ~ 2.29%)，CaCO3含量高(10.1% ~ 24.9%)，pH值为中性和微碱性(7.01 ~ 7.81)。各监测站最主要的元素是钙交换性，其值在51.52 ~ 74.91 cmol+/kg之间。其他可交换碱性阳离子(Mg、Na、K)含量相对较低。CEC值在36.12 ~ 81.13 cmol+/kg之间变化，表明土壤类型重有机质。
