NFK useable field-moisture capacity (volume moistness (Vol%) of field-moisture capacity minus Vol% of permanent wilt point)
S, U, L, T indication to soil type (sands, silts, clays;
N, H lower moor, upper moor) for the determination of capillary rise
depth to ground water and capillary rise
TG depth to ground water (value FLW in m) for the determination of KR
