“…Oxygenated functional groups, for instance hydroxyl and carboxyl, can enhance soil CEC and thus improve soil fertilizer retention capacity while preventing secondary salinization resulting from excessive fertilizer application to a certain extent (Jiang et al., 2012; Zhang, Bing, et al., 2022). This will release alkaline ash in BC and elevate pH, but it will also release Ca and Mg ions for exchanging Na + in soil (Xu et al., 2023; Zhang, Bing, et al., 2022). Generally, the ball‐milled BC can decrease the soil conductivity affected by salt, subsequently alleviating salt stress on crops and increasing crop yields (Zhang, Bing, et al., 2022).…”

The continuous growth of the world's population has led to an increased demand for food. Biochar (BC) contains valuable functional groups and nutrients, which have been demonstrated to enhance soil properties and boost crop yield. Nonetheless, unmodified BC exhibits significant alkalinity and a large salt concentration; thus, its efficacy in improving saline‐alkali soil remains a matter of contention. Therefore, scholars aim to address the aforementioned limitations by adapting BC. In this paper, a summary is given of the methods used to modify BC and the effects of modified BC on salt‐affected soil and saline‐alkali soil properties, including pH, nutrients and microbial activity. The effects and principles of different modifiers and modification methods on BC's physicochemical properties (porosity and functional group content and type, etc.) were revealed. Furthermore, the principle of soil improvement by modified BC varies depending on the modification method. Although modified BC can effectively enhance salt‐affected soil, its excessive application and improper selection of modifiers can aggravate Na+ toxicity or introduce other pollutants into salt‐affected soil. Therefore, using modified BC with care is imperative according to the actual situation. In this review, we provide a detailed introduction to the methods and principles of BC modification for saline‐alkali soil. Furthermore, we identify the shortcomings and future research directions in this field. These insights are valuable when choosing proper BC modification methods for salt‐affected soil.

“…The improved materials can improve the cohesive force of the weathered soil film of the natural redbeds. Adhesives, building materials, and plant materials improve the molecular structure of the redbed weathered soil membrane, while mineral materials and cellulose improve the ion distribution of the redbed weathered soil membrane [39,40]. The improved materials can improve the cohesive force of the weathered soil film of the natural redbeds.…”

Natural redbeds are widely distributed throughout China. Ecological restoration entails implementing measures according to the local conditions and obtaining local materials, ensuring ecological environment conservation and restoration in a scientific manner. The mud skin of weathered redbed soil is often used to control soil desertification and repair slope, and its integrity is important to measure the repairing effect. However, most of the materials used for the improvement of weathered redbed soil contain harmful chemicals, bear high costs, and aggravate environmental pollution. At present, the knowledge about different kinds of improvement materials for Chinese different zones is unclear. To solve this problem, we considered naturally weathered redbed soil as the raw material, selected 77 kinds of improved materials, and tested the integrity of the natural redbed weathered soil after adding the improved material; then, we compared it with the natural redbed weathered soil with no added materials. Then, we put forth a classification standard for the materials, discussed the driving environmental factors, formulated the suitable zoning of the materials, and defined the improvement effects of different materials on the weathered redbed soil in different regions of China. The results suggested that, for weathered redbed soil, nano water-based adhesives were most suitable for the south-western, north-western, south-eastern, north-eastern, and northern regions of China and can be widely used in other regions as well. Starch was the least suitable material for the north-western, north-eastern, and northern regions of China. The most unsuitable material for South-West China was larch tannin extract; wormwood straw was the most unsuitable for South-East China. The modified material that was not suitable for use in most zones was starch. Thus, our study provides a concrete scientific basis regarding the effectiveness of different materials in addressing natural hazards caused by weathered redbed soil in China.

“…Anthropogenic activities with high environmental impact are causing the progressive degradation of natural resources, and water and soil are among the most affected. High salinity levels of soil and water are considered environmental stresses of concern, as they can lead to the loss of agricultural soil and a sharp reduction in crop yields [1,2]. Mediterranean countries are particularly affected by salinity, as many coastal agricultural areas are experiencing the progressive salinization of soils and waters [3].…”

“…A substantial contribution to this phenomenon is related to effects brought about by extreme events caused by climate change, such as flooding and rising sea levels [4]. About 7% of the earth surface is affected by salinity, which has degraded more than 900 million hectares of total arable land on a planetary scale [2]. Salinity determines annual economic losses of USD 27 billion to agricultural production [2].…”

Water and soil salinization significantly reduce crop yields. Among the strategies developed to counteract salt stress, biostimulants can maintain crop productivity, reversing its impact. In this context, there is interest in finding new substances that could act as biostimulants. Recently, the biostimulatory potential of Lemna minor L. (duckweed) extracts has been shown. This work aimed to highlight whether an extract from duckweed (Lemna extract—LE) could protect maize grown in salinity, exploring the mechanisms induced to improve crop resistance. Plants were grown by applying two concentrations of NaCl (150 and 300 mM), and some physiological, morphological, and biochemical traits were studied in control and salt-stressed samples, treated or not with LE. Salinity decreased shoots, roots, pigment, and soluble protein. LE prompted ameliorative changes at the root level and increased photosynthetic pigment and soluble protein. Furthermore, concerning the oxidative impairment provoked by salt stress, LE enhanced the cellular redox state, contrasting H2O2 and MDA accumulation and positively affecting the activity of superoxide dismutase (SOD—EC 1.15.1.1) and catalase (CAT—EC 1.11.1.6). The assessment of some mineral nutrients showed that LE stimulated their acquisition, especially for the highest salt dosage, explaining some benefits found for the parameters investigated.
