“…Many researchers have found that biochar has significant advantages in terms of improving soil structure, increasing soil nutrients, and ensuring better quality and increased plant yields when added to soil as an organic amendment [ 8 , 9 , 10 , 11 ]. Biochar reduces soil bulk density, increases porosity, and improves particle size distribution because of its porous structure and low bulk density.…”

The rational development and efficient utilization of saline soils can alleviate the problem of insufficient arable land faced by agricultural production in China. A prominent problem is improving soil salt and water conditions for promoting land resources’ productivity in coastal areas. Biochar is widely used for soil improvement, as it has remarkable properties. A pot experiment was conducted to study the effects of two kinds of biochar (common biochar and acid-modified biochar) with three addition rates (2%, 4%, and 8%) on the growth, yield, photosynthetic characteristics, and quality of spinach. The results revealed that 2% and 4% common biochar increased the plant height, stem diameter, and leaf area index, effectively improving the yield of spinach and water productivity, while 8% common biochar was detrimental to the growth of spinach to some extent. Acid-modified biochar significantly benefited the growth and increased the water productivity of spinach, ensuring high yields, while also improved quality. Similarly, acid-modified biochar was less effective at high additions than at low-to-medium additions. The integrated biological response version 2 (IBRV2) values under acid-modified biochar treatments were all significantly higher than those under common biochar, but there is no significant difference among three treatments in the same biochar group, which suggested a pronounced amelioration in spinach growth within saline-alkali soil upon the incorporation of acid-modified biochar. Overall, applying acid-modified biochar at the rate of 4% exhibited enormous potential for increasing the yield and quality of spinach in saline soils.

“…The provision of manure can also increase soil organic P fraction, C availability and soil microbial activity [34], as well as increasing soil CEC [33]. Application of lime to soil whether in form of dolomite, agricultural lime, biochar, straw, zeolite, Rock phosphate or plant waste can increase soil pH [19,20,23,24,25,26,28,29]. Soil pH increase will affect the availability of main nutrients for plants and will suppress the solubility of iron and aluminum.…”

“…Application of Rock phosphate-based ameliorants can increase soybean production and along with manure addition may increase the availability of P, Ca, organic matter and cation exchange capacity [24]. Ameliorant from biochar is able to increase water pH and increase the absorption of Al, Fe, Co, Cd, Ni and Zn [25,26]. Moreover, the application of ameliorant from compost affects the physical, chemical and biological processes of the soil [27]; while combination of straw and zeolite with lime can increase soil pH, cation exchange and reduce Al and Fe solubility [28,29].…”

Soil acidity, high solubility of Al, Fe and S as well as low soil fertility are obstacles to rice production in acid sulphate soil. However, rice production can be increase by improving land quality through application of ameliorant. The study was carried out on acid sulphate soil in Banyu Urip Village, Banyuasin Regency, South Sumatra during wet season of 2020. The study aimed to determine the effect of ameliorant to rice production in acid sulphate soil. The study used Randomized Block Design with 6 replications. The ameliorant tested were P1 = control (without ameliorant), P2 = Dolomite [CaMg(CO3)2] (2 t.ha−1), P3 = Agricultural lime/Calcium Carbonate [CaCO3] (2 t.ha−1), P4 = Manure (2 t.ha−1), P5 = Biochar (5 t.ha−1), P6 = dolomite + manure + biochar (1/3 of each dose) and P7 = agricultural lime + manure + biochar (1/3 of each dose); in which Swampland Soil Test Kit was used to determine the ameliorant doses. The ameliorant was spread across the soil surface two weeks before planting, then mixed using hoe at the same time with the second tillage. Parameters observed were agronomic characteristics including plant growth and yield components. Results showed that the provision of ameliorant was able to increase plant growth and productivity of rice in acid sulphate soil. The highest productivity was found in treatment P7 (3.96 t.ha−1 dry unhusked grain) which applied combination of agricultural lime, manure, and biochar.

“…Biochar is a new type of soil amendment, known as "black gold", and is used by international academics. Many researchers have shown that biochar, as an organic amendment, has significant advantages in terms of improving soil structure, increasing soil nutrients, and ensuring better quality and increasing plant yields when added to soil [9,10]. Xu [11] reported that a biochar addition rate of 3 t•ha −1 ensured stable maize yields when fertilizer application was reduced by 30%, and 3, 5 and 7 t•ha −1 biochar significantly increased maize yields at adequate nutrient levels.…”

The cultivated land area in China is approaching the red line for farmland protection. Newly reclaimed land possesses a large exploratory potential to become a reserved land resource. Identifying a fertilization strategy is vital for improving the poor properties and weak fertility of newly reclaimed land. An experiment was conducted to study the effects of traditional compound fertilizer (Fc) or bio-organic fertilizer (Ft), alone or in combination with biochar addition (6.85 t·ha−1 and 13.7 t·ha−1) on the growth, photosynthesis, yield and quality of Chinese small cabbage (CSC) plant. The results showed that compared to single compound fertilizer application, bio-organic fertilizer application promoted the plant’s growth, indicated by the plant height, stem diameter and leaf area index (LAI), and significantly enhanced the yield and dry matter accumulation of CSC. In terms of the combination with biochar, the promoting effects were positively related to the biochar addition rate in the compound fertilizer group, while it was better to apply bio-organic fertilizer alone or in combination with biochar at a low rate of 6.85 t·ha−1. The highest yield was obtained under B2Fc and B1Ft with 29.41 and 37.93 t·ha−1, respectively, and the yield under B1Ft was significantly higher than that under B2Fc. The water productivity (WP) significantly improved in response to both kinds of fertilizer combined with biochar at 6.85 t·ha−1. There was a significant difference between the photosynthetic characteristics of plants treated with single-compound fertilizer and those treated with bio-organic fertilizer. The photosynthetic characteristics increased under compound fertilizer combined with biochar, while they regressed under bio-organic fertilizer combined with biochar. The quality of CSC, especially that of soluble sugars and total phenolics, improved under single bio-organic fertilizer application compared with that under single-compound fertilizer. The nitrite content of the plants increased with increasing biochar addition rate in both fertilizer groups. In conclusion, there is a significant promoting effect of applying bio-organic fertilizer to replace chemical fertilizer alone or combining compound fertilizer with low-rate biochar addition on newly reclaimed land. It is a recommended fertilization strategy to substitute or partially substitute chemical fertilizer with bio-organic fertilizer combined with biochar in newly reclaimed land, and it is of great significance to achieve fertilizer reduction.
