محتوى المياه في التربة (نسبة مئوية حجمية) عند امتصاص 33 كيلو باسكال و1500 كيلو باسكال
متوقّع على 6 أعماق عادية (0 و10 و30 و60 و100 و200 سم) بدقة 250 مترًا
تستند نقاط التدريب إلى مجموعة عالمية من ملفات التربة:

ملاحظة: هذه القيم هي قيم فعلية تم قياسها وربطها بمحتوى التربة، ولم يتم استخدام أي دوال نقل التربة (باستثناء ملء الكثافات الظاهرية الناقصة في NCSS). يمكنك الاطّلاع هنا على سعة المياه المتاحة
بالملليمتر (يتم احتسابها كفرق بين السعة الحقلية ونقطة الذبول مضروبًا في سمك الطبقة) لكل طبقة.
لا تشمل هذه القائمة القارة القطبية الجنوبية.
