Abstract

The aim of this study was to investigate the effect of olive pomace biochar (OB) application on the mechanical, physical and chemical properties of Vertisols. For this study, soil samples classified as Vertisol in Çanakkale, where internal drainage and surface ponding are major problems, were used. The OB was produced at 450°C and then mixed with 0% (control), 3%, 6% and 9% of the soil by weight. Various soil parameters, including the Atterberg limits (liquid limit [LL], plastic limit [PL], plasticity index [PI], shrinkage limit [SL]), saturated hydraulic conductivity (K_sat), field capacity (FC), total carbon (TC) and total nitrogen (TN), were determined. The values of all the soil parameters increased, except for the PI. Moreover, the K_sat value increased by 127% and 136% with 6% and 9% OB application, respectively, compared to that of the control. Additionally, the FC, TN and TC levels in the soils increased in response to biochar application. In conclusion, OB application has a positive effect on the specific properties of Vertisol and can improve its physical properties.

橄榄渣生物炭对植物某些特性的影响

本研究的目的是研究橄榄渣生物炭（OB）的施用对versols的机械、物理和化学性质的影响。在本研究中，使用了Çanakkale中分类为Vertisol的土壤样品，其中内部排水和地表积水是主要问题。在450°C下生产OB，然后与0%（对照）、3%、6%和9%的土壤混合。测定了Atterberg极限（液限[LL]、塑性极限[PL]、塑性指数[PI]、收缩极限[SL]）、饱和导水率（Ksat）、田间容量（FC）、总碳（TC）、总氮（TN）等土壤参数。除PI外，其他土壤参数均增大。此外，与对照相比，施用6%和9% OB的Ksat值分别增加了127%和136%。此外，施用生物炭增加了土壤中FC、TN和TC的含量。综上所述，添加OB对Vertisol的性能有积极的影响，可以改善其物理性能。

期刊介绍： Human intervention in the control of water for sustainable agricultural development involves the application of technology and management approaches to: (i) provide the appropriate quantities of water when it is needed by the crops, (ii) prevent salinisation and water-logging of the root zone, (iii) protect land from flooding, and (iv) maximise the beneficial use of water by appropriate allocation, conservation and reuse. All this has to be achieved within a framework of economic, social and environmental constraints. The Journal, therefore, covers a wide range of subjects, advancement in which, through high quality papers in the Journal, will make a significant contribution to the enormous task of satisfying the needs of the world’s ever-increasing population. The Journal also publishes book reviews.
