In tshi survey the interpretation identified the location and depth to a petrogypsic layer, petrocalcic layer and/or rock. Depth was measured as the vertical distance from the soil surface and the soil surface is the top of the mineral soil. Hardpans are a common and widespread feature of soils across Abu Dhabi. They are closely associated with the occurrence of specific soil types. || تقييم عمق الطبقة الصلبة أو الصخور يقوم بتقييم عمق التربة حتى الوصول إلى قيود فيزيائية تقلل بشكل كبير من حركة الماء والهواء عبر التربة، أو التي تشكل بيئة غير مناسبة جذريًا لنمو جذور النباتات، مما يحد من نموها للأسفل.<\/SPAN><\/P><P><SPAN /><\/P><P><SPAN>في هذا المسح، حدد التقييم موقع وعمق كل من:<\/SPAN><\/P><P><SPAN /><\/P><P><SPAN>الطبقة البتروجبسية (Petrogypsic layer)<\/SPAN><\/P><P><SPAN>الطبقة البتروكالسية (Petrocalcic layer)<\/SPAN><\/P><P><SPAN>الصخور<\/SPAN><\/P><P><SPAN>تم قياس العمق على أنه المسافة العمودية من سطح التربة، ويُعرّف سطح التربة على أنه أعلى طبقة من التربة المعدنية.<\/SPAN><\/P><P><SPAN /><\/P><P><SPAN>تُعد الطبقات الصلبة (Hardpans) من الخصائص الشائعة والمنتشرة على نطاق واسع في تربة أبوظبي. وهي مرتبطة ارتباطًا وثيقًا بوجود أنواع معينة من التربة.<\/SPAN><\/P><\/DIV><\/DIV><\/DIV>",
