摘要
橄榄厂废水(OMWW)的扩散可以提供一种适当的管理选择，以增加这种农业副产品的价值，例如提高土壤肥力和植物生产力。本研究的主要目的是评估长期(20年)施用OMWW(固定剂量为50 m3 ha - 1)对土壤根际特性和老橄榄树(80年)生长和生产力的影响。方法试验点分为4个经OMWW处理的样地(T1、T2、T3和T4)和4个未处理的对照样地(C1、C2、C3和C4)。自2004年以来，每个处理地块每年2月接受固定剂量的50 m3 ha - 1的甲基水。结果表明:添加OMWW提高了土壤保水能力(SWRC)和有机质含量(OMC)，提高了土壤磷(P)和钾(K)水平;土壤根际微生物区系活性显著增强。结论自2004年以来，在50 m3 ha−1的橄榄园土壤表面施用somww对树木的营养生长没有负面影响，满足植株对P、K、N的需求。我们的研究表明，OMWW可以改善土壤性质，丰富土壤所需的矿物质。
Long-term effects of olive mill waste waters spreading on the soil rhizospheric properties of olive trees grown under Mediterranean arid climate
Context
The spreading of olive mill waste waters (OMWW) could offer an appropriate management option to add value to this agricultural by-product, such as to increase soil fertility and plant productivity.
Aims
The main objective of this work was to evaluate the effects of the application of OMWW (at a fixed dose of 50 m3 ha−1), in the long term (20 years) on the soil rhizospheric properties and on old olive trees (80 years old) growth and productivity.
Methods
The experimental site consists of four plots treated with OMWW (T1, T2, T3 and T4) and four ‘control’ plots (C1, C2, C3 and C4), without any treatment. The treated plots have received each a fixed dose of 50 m3 ha−1 of OMWW in February of each year since 2004.
Key results
The results obtained showed that the addition of OMWW increased the soil water retention capacity (SWRC) and its organic matter content (OMC), as well as the augment of phosphorus (P) and potassium (K) levels. The activity of the soil rhizospheric microflora was significantly enhanced.
Conclusions
OMWW application to the soil surface in an olive orchard at 50 m3 ha−1, since 2004, had no negative effects on the tree’s vegetative growth and satisfied plant P, K and N requirement.
Implications
Our study showed that OMWW can enhance the soil properties and enrich the soil with necessary minerals.
