“…Carter et al (2013) also showed that the combined application of biochar and organic fertilizer changed soil structure and improved soil chemical properties. Tian et al (2021) showed that biochar improved soil quality in purple soils, thereby promoting increased rapeseed yield. This study also proved that the application of biochar combined with organic and inorganic fertilizers greatly improved soil quality.…”

Biochar is a kind of organic matter that can be added into the soil as a soil amendment to improve its quality. What are the effects of using biochar on purple soil and soybeans? Can the use of biochar reduce the use of fertilizers? This is our concern. Therefore, we carried out this study. The objectives of our study were to evaluate the effects of biochar, inorganic and organic fertilizer application on plant growth, chlorophyll content, photosynthetic gas exchange, and yield of soybean as well as fertility and microbial community in purple soil, and to appraise the possible reduction rate of inorganic fertilizer under the biochar application. A pot experiment was conducted with three levels of biochar, two levels of inorganic fertilizer, and two levels of organic fertilizer in a randomized complete block. The results indicated that the low rate of biochar together with half rate of inorganic fertilizer and organic fertilizer increased the plant growth of soybean. Meanwhile, the chlorophyll content, root growth, and yield of soybean were increased by 16.61, 197.73, and 96.7%, respectively, with biochar compared with no biochar. The high rate of biochar with half rate of inorganic fertilizer and organic fertilizer can promote the exchange of photosynthetic gas in soybean, and the photosynthetic rate increased by 45.25% compared with the blank control. At the full pod stage, the nitrogen content, phosphorus content, and potassium content of the whole plant under the high rate of biochar were 28.35, 13.65, and 28.78%, respectively, higher than that of the blank control. The application of biochar increased nitrogen, phosphorus, and potassium uptake of soybean. The high rate of biochar with half rate of inorganic fertilizer and organic fertilizer can improve soil nutrient content and soil microbial community. Compared with no biochar treatments, total organic carbon (TOC) increased by 740.28%, and cation exchange capacity (CEC) increased by 54.17%. Phospholipid fatty acid (PLFA) increased by 65.22%, and all kinds of soil microorganisms increased to varying degrees. In conclusion, the application of biochar can reduce the use of organic and inorganic fertilizers, improve the agronomic traits and yield of soybean, and play a positive role in soil nutrients and soil microorganisms.

“…Total nitrogen, phosphorus, and potassium are essential elements for cell metabolism and plant growth ( Sung et al, 2015 ). Available nitrogen, phosphorus, and potassium can be used as indexes to evaluate soil fertility ( Tian et al, 2021 ). Therefore, these essential factors were used as indicators of artificial soil quality in this study.…”

The construction of high-speed roads has resulted in large amounts of steep and exposed cut slopes, posing more potential hazards in areas with mountains and hills. Vegetation restoration is an effective and environmentally-friendly way to restore exposed slopes using outside soil spray seeding, though it is difficult to establish a vegetation cover. Spraying artificial soil on high and steep slopes is a challenging task as it is difficult to keep the fluid mixture on sloped surfaces. Because of these challenges, this study applied different combinations of cement and soil aggregates in artificial soil, measuring final soil properties after one growing season. Experimental results showed that there were substantial differences in all basic soil parameters and in the soil quality index after different treatments. In particular, adding 5–10% cement content could improve the adhesion of artificial soil without remarkably reducing soil quality; adding 0.09% of soil aggregate was also beneficial to soil nutrient availability. These findings indicate that the combination of cement and soil aggregates could be applied in artificial soils for the ecological restoration of steep slope vegetation. Adding cement to the soil increased the alkaline levels of the soil, so it is important to reduce artificial soil pH in the future. The application of a cement and soil aggregate should be considered in the field for the ecological restoration of slope vegetation, and the impact of this addition on slope stability and vegetation growth should be explored with further research.

“…These ashes must have an appropriate destination to avoid contamination of the environment. Among these destinations, ashes can be used as an alternative source for mineral fertilization and the two forms of fertilization can be associated (Li et al, 2021;Tian et al, 2021).…”

“…The use of biochar can increase soil fertility by providing some cations such as Ca, Mg, K, Mn, Zn and Cu and also through the presence of other nutrients such as P and N. Another factor that can be influenced by biochar application is the reduction of soil acidity, increase in carbon contents and reduction of heavy metals (Li et al, 2021;Tian et al, 2021;Zhang et al, 2021).…”

“…The use of biochar has been reported in some crops: in papaya associated with microorganisms (Matos et al, 2018), in rapeseed associated with mineral fertilizers (Tian et al, 2021) and in Brazilian peppertree (Sales et al, 2018). This residue supplies nutrients to plants and can increase their performance, increase the contents of total chlorophyll, chlorophyll a and chlorophyll b, as well as improving the chemical attributes of the soil (Matos et al, 2018;Sales et al, 2018;Li et al, 2021).…”

Brazil stands out in the international scenario as the largest producer of sugarcane, processing billions of tons. Thus, this activity generates residues, such as ashes from bagasse burning and straw from sugarcane cleaning and from the production of sugar, alcohol and thermal energy. Therefore, the objective was to evaluate the initial performance and chlorophyll content of pigeon pea and the chemical attributes of the soil after application of ash doses. The experiment was conducted in 2021, in a greenhouse located in southwestern Goiás, Brazil. The design used was completely randomized, composed of five ash doses: 10, 20, 30, 40 and 50 Mg ha-1 and a control treatment, with four replicates, totaling 24 experimental units. The use of only ash as a fertilizer source causes linear increases in the initial growth of pigeon pea and in the contents of total chlorophyll and chlorophyll b, reaching the maximum increments with the estimated ash doses of 35.9 and 38.9 Mg ha-1. Applications of high ash doses promoted improvements in soil fertility, with increase in pH, P, K and base saturation as well as reduction in aluminum content and aluminum saturation. Calcium and magnesium contents reached the maximum increments with the estimated ash doses of 39.5 and 66.7 Mg ha-1, respectively.
