Management of the soil environment using biochar and zeolite in various combinations: impact on soil condition and economical aspects
Purpose
Both biochars (BCs) and zeolites (Zs) are defined as soil conditioners affecting various parameters of soil environment. In most cases, BCs and Zs are characterized by well-developed specific surface area, high porosity, and excellent sorption properties, which is highly helpful in soil reclamation or conditioning. This literature review compares impact of BCs and Zs on the physicochemical properties of various soils as well as economic aspects of their synthesis.
Materials and methods
The review was prepared based on the articles published in the last 5 years (2018–2023). The articles were selected from the ScienceDirect® database using the keywords: ‘biochar/zeolite impact on soil physicochemical properties’, ‘biochar/zeolite impact on water retention of soil’ and ‘biochar/zeolite economic aspects’.
Results and discussion
Based on the available data, it can be stated that both BCs and Zs have good sorptive properties, which usually contributes to better growth of crops. Comparing them and choosing which one is more promising depends on the specific purpose and type of soil to which they are to be applied. BCs usage contributes mainly to providing organic matter and improving soil structure, while Zs enhance soil water retention. The profitability of BCs/Zs production depends largely on the precursor as well as the synthesis method.
Conclusions
Due to the fact that impact of synthetic Zs on the soil environment is much less frequently investigated than that of BCs, the research using Zs and various soil types is especially needed. In some cases, it is advisable to apply biochar (BC) and zeolite (Z) simultaneously. Combinations of these materials may provide benefits in soil structure, water retention, and fertility. Such mixed techniques should be investigated in the near future.
