| Zusammenfassung |
| The study analysed soil organic carbon (SOC) and hot-water extractable carbon (HWC) in an
agricultural Mediterranean area of Southern Spain under different land management:
Conventional tillage (CT); Conventional tillage with the addition of oil mill waste, also
known as alperujo (A); Conventional tillage with the addition of oil mill waste olive leaves
(L); No tillage with chipped pruned branches (NT1); and No tillage with chipped pruned
branches and weeds (NT2).
SOC values in CT, A, NT1 and NT2 decreased with depth. In L, SOC also decreased with
depth, although there was an increase of 89% from the first (0–10Âcm) to the second horizon
(10–16Âcm). Total SOC stock (considering the entire soil profile) was very similar under A
(101.9ÂMg ha-1), CT (101.7 Mg ha-1), NT1 (105.8 Mg ha-1) and NT2 (111.3ÂMg ha-1).
However, SOC under L was significantly higher (p |
