“…Proportional to biochar application rate CEC increased linearly in treatments T1, T3 and T5. This phenomenon was also stated by Sun et al (2016) when applied wheat straw biochar at different rates (5, 10 and 20 g/kg) to saline soil in Yellow River Delta. Similar trends were observed in other studies and reports (Glaser et al 2002;Rondon et al 2007;Blackwell et al 2010;Van Zwieten et al 2010;Ullah et al 2018).…”

Biochar is projected as a soil conditioner to amend soil physical and chemical properties. However, behavior of biochar in alkaline soils under arid and semi-arid conditions in Egypt not much investigated. In this study, field experiments were carried out under greenhouse conditions to explore the effect of applying biochar and sugarcane bagasse with two different ways and at three different rates (10, 20 and 30 ton ha-1) on some properties of alkaline clay loam soil and tomato growth and yield. The experiments were conducted for two successive seasons of 2015 and 2016. Mixing biochar with top surface soil at rates of 20 and 30 ton ha-1 reduced particle and bulk density and increased the porosity and water holding capacity. The results indicated that biochar application did not affect soil pH, however, decreased EC e and increased soil organic carbon, exchangeable cations and cation exchange capacity. Addition of biochar by mixing through the top-twenty-centimeters of soil surface was more effective than applying as a thin layer under the toptwenty-centimeters of soil surface on improving tomato growth. Application of organic residues such as sugarcane bagasse caused limited positive effects on soil physical-chemical properties. In comparison, this shows the benefit effect of pyrolysis for organic residues on soil properties. Tomato growth and yield only was affected significantly (P < 0.05) by biochar application at a rate of 20 ton ha-1 .

“…The application of organic amendments in SAS is considered a useful and effective way to increase soil fertility and enhance crop growth [31,157]. The application of organic amendments in SAS increased the biomass yield of alfalfa, Medicago sativa [182]; barley, Hordeum vulgare [31]; cotton, Gossypium hirsutum [143]; maize, Zea mays [32,159,183]; onion, Allium cepa [142]; rice, Oryza sativa [31,153,184]; seepweed, Suaeda salsa [185]; sweet fennel, Foeniculum vulgare [186]; tomato, Solanum lycopersicum [187]; and wheat, Triticum aestivum [139]. The quantitative and qualitative improvements in the growth and yield attributes of crops as affected by abiotic stresses in the presence of different additives might be due to the enhanced photosynthesis, cholorophyll contents, stomatal conductance, water-use efficiency, and synthesis of metabolites [137,[188][189][190][191].…”

Abiotic Stress in Plants

High salt concentration in soil is a major abiotic stress, which adversely influences the growth, overall development, and productivity of crops. More than 20% of the land of the world used for crop production is adversely affected by high salt concentration. The problem of salt stress becomes a major concern when previously fertile, productive agricultural lands are salinized more profoundly as a result of anthropogenic activities along with natural causes. Therefore, this review is focused on various aspects of salt-affected soils (SAS), their effects on plants, and different approaches for reclamation of SAS to enhance the potentiality for crop production. Salt-affected soils are categorized into saline, saline-sodic, and sodic soils based on the amount of total soluble salts as expressed by electrical conductivity (EC), sodium adsorption ratio (SAR), exchangeable sodium percentage (ESP), and soil pH. The inhibition of plant growth in saline soils is mainly induced by osmotic stress; reduced uptake of essential macro-and micronutrients, including nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), iron (Fe), manganese (Mn), zinc (Zn), and copper (Cu); and specific toxicities of sodium (Na) and chloride (Cl). Sodic soils adversely affect the plant through high soil pH and poor physical condition resulting from an excessive amount of exchangeable Na. Different plants respond to salt stress in different extents. Saltaffected soils must be reclaimed to restore their productivity for increasing food production. The approaches for the management of SAS include leaching, incorporation of different organic and inorganic amendments, mulching, and development of salt-tolerant crops. The suitability of approaches depends on several considerations such as cost of reclamation, the time required, the extent of the salt stress, soil properties, availability of technology, and other environmental factors. Among different strategies, the incorporation of organic amendments is beneficial, costeffective, environment friendly, and sustainable for amelioration of salt stress and enhancement of crop production due to the extensive roles of organic amendments in improving the soil's physical (structural stability, porosity, and permeability), chemical [pH, EC, ESP, organic matter, cation exchange capacity (CEC), and Na leaching], and biological and/or biochemical (microbial abundance, microbial activity, biomass carbon, and enzymatic activities) properties.

“…Recent studies on the negative effect of high BC application on soil-plant system revealed that addition of BC at levels of 10, 20 and 30 t ha -1 produced positive influence on grain yield of winter rye, with 20 t ha -1 resulting in the highest grain yields (Kraska et al, 2016). Pot experiments revealed that S. salsa yield increased from 11.7 to 115% with WS application in the range of 5-10 g kg -1 , when compared with control (Sun et al, 2016). However, as BC level increased to 20 g kg -1 , the yield decreased to 102%.…”

Maize-straw biochar (BC) was applied in a black soil area in Northeast China for investigating its effects on crop yield, soil physical properties and nitrifying bacteria. In this study, BC forms BC1, BC2 and BC3 were incorporated at levels of 15.75, 31.50 and 47.25 t ha -1 , respectively, from 2013 to 2014. The control soil was treated with chemical fertilizer (NPK). The results showed that yields of soybean were significantly improved overall due to BC applications, compared with the control. Meanwhile, average soil compaction values of 0 -20 cm deep soil were decreased from 17.9% to 47.4%. Biochar supplementation decreased the soil wilting coefficients, but increased saturated water content. The available soil water content increased from 0.211 to 0.329 cm 3 cm -3 (R 2 = 0.97), whereas the bulk density decreased from 1.42 to 1.40 g cm -3 (R 2 = 0.97) in response to BC supplementation. Unexpectedly, soybean yields began to decline at 31.50 and 47.25 t ha -1 of BC application. as well as soil aggregate stability, available water content, and capillary pores, mainly. Moreover, the BC supplementation significantly affected soil ammonia-oxidizing archaea (AOA) abundance. These results demonstrate that BC has positive potential for enhancing crop and soil properties performances in black soil at the level of 15.75 t ha -1 under continuous soybean system.
