“…Similar BD values in such deposits have been reported by Wojtasik (1989) and Rząsa et al (1999); and higher values have been reported by Gilewska and Otremba (2018), Otremba et al (2020) and Kozłowski et al (2022). The effect of mineral fertilization on bulk density and porosity was also tested by Zhao et al (2013) and Phares and Akaba (2022) who did note any improvement in these parameters. In contrast Chaduhary et al ( 2017) observed a significant decrease in density and a significant increase in porosity as a result of many years of NPK fertilization.…”

The study assessed the effect of long-term, diversifi ed NPK fertilization and cereal monoculture on the physical and water properties of post-mining Technosols. The research was carried out in 2022 at an experimental plot established in 1978. A fi eld experiment was established on the internal heap of the Pątnów KWB Konin (Brown Coal Mine Konin). In the research area, since the beginning of the experiment to the present day, an annual cereal crop rotation has been cultivated (winter rye alternating with winter wheat). In 1988, the area was divided into three experimental sections that received different rates of NPK fertilization. The study area consisted of three plots -marked in the paper as: 0 NPK, 1 NPK, 2 NPK. In each section the morphology of three soil profi les were described. From each genetic horizon, samples with a disturbed and intact structure were collected. The results of the analyzes were treated as repetitions and statistically processed. The collected material was used to analyze the basic physical, water and chemical soil properties. The tested soils were classifi ed as Spolic Technosols (Pantocalcaric, Katodensic, Pantoloamic, Ochric). Mineral fertilization improved the physical and water properties in the surface horizons, but no effect was observed on subsoil properties. Fertilization with a single NPK application was found to be effective and additional applications were considered superfl uous.

“…This conclusion is consistent with findings from earlier research. Studies have shown that biochar can improve soil quality, which solves the problem of soil consolidation due to excessive fertilizer application and achieves increased crop yield [34][35][36]. On the one hand, biochar possesses a high specific surface area, and is also rich in mineral components that enable it to absorb soil nutrients directly, thereby reducing nutrient loss [37,38].…”

“…Biochar holds excellent potential for use as an effective and cost-efficient soil amendment [34,66]. The biochar treatment combined with reduced chemical fertilizers resulted in an increase in net income of 0.06% to 21.30% in 2021 and 27.62% to 47.80% in 2022, as observed in this study (Table 4), which indicated that the utilization of biochar did not decrease the economic efficiency of pod pepper under the condition of chemical fertilizer reduction, but was beneficial to economic efficiency.…”

Chemical Fertilizer Reduction Combined with Biochar Application Ameliorates the Biological Property and Fertilizer Utilization of Pod Pepper

et al. 2023

Biochar is frequently utilized as a helpful amendment to sustain agricultural productivity. However, it remains uncertain whether biochar can effectively replace chemical fertilizers, especially in karst regions. To investigate the effects of co-applying biochar and chemical fertilizer on the biological characteristics and fertilizer uptake of pod peppers, as well as to determine the optimal ratio of biochar to chemical fertilizers, a two-year field experiment was conducted in southwest China. The results showed that, compared to the locally typical chemical fertilizer treatment (CF), the combined application of biochar and chemical fertilizer significantly increased the yield of both fresh and dry pod pepper. Chemical fertilizer reduction and biochar application also ameliorated fruit quality, increased nutrient accumulation, and improved fertilizer utilization efficiency. What is more, although the employment of biochar made production costs higher, the reduction in chemical fertilizers and the increase in yield improved economic efficiency, especially in the CF70B treatment (70%CF + biochar). In conclusion, moderate amounts of biochar instead of chemical fertilizers may be a valid nutrient management strategy for pod pepper in the karst mountain areas, which is beneficial for maintaining yield stability, improving quality, and increasing net income.

“…Compared with the TF treatment, the yield of fresh pepper increased by 24.38–50.03% in 2021 and 31.61–88.92% in 2022, whereas the yield of dry pepper increased by 14.69–40.63% in 2021 and 21.44–73.29% in 2022. It has been shown that biochar can improve soil quality, which not only solves the problem of soil consolidation due to excessive fertilizer application but also achieves increased crop yield ( Phares and Akaba, 2022 ; Yan et al., 2022 ; Wang et al., 2023 ). Biochar is rich in mineral elements and has a large specific surface area that can directly adsorb nutrients from the soil and reduce nutrient loss ( Li et al., 2023 ; Lv et al., 2023 ).…”

“…These substances are easily converted into active components that can be absorbed and used by plants with the help of microorganisms, facilitating the accumulation of nutrients in plants ( Singh et al., 2008 ; Wang et al., 2020 ). Organic amendments applied to soil can increase the activity of soil microorganisms and soil nutrient content, which is also beneficial for promoting nutrient decomposition and release, as well as plant uptake and utilization of nutrient elements ( Srivastava et al., 2012 ; Kuppusamy et al., 2016 ; Phares and Akaba, 2022 ). In this study, the application of biochar and vermicompost alone or in combination not only significantly increased the accumulation of NPK ( Figure 3 ) but also significantly improved the fertilizer utilization efficiency ( Table 3 ).…”

Recently, biochar (B) and vermicompost (V) have been widely used as amendments to improve crop productivity and soil quality. However, the ameliorative effects of biochar and vermicompost on the continuous cropping of pepper under open-air conditions, particularly in the karst areas of southwestern China, remain unclear. A field experiment was conducted to study the effects of biochar and vermicompost application, alone or in combination, on the yield, quality, nutrient accumulation, fertilizer utilization, and economic benefits of continuous pepper cropping from 2021 to 2022. The experiment included six treatments: CK (no fertilizer), TF (traditional fertilization of local farmers), TFB (TF combined with biochar of 3000 kg·ha-1), TFV (TF combined with vermicompost of 3000 kg·ha-1), TFBV1 (TF combined with biochar of 1500 kg·ha-1 and vermicompost of 1500 kg·ha-1), and TFBV2 (TF combined with biochar of 3000 kg·ha-1 and vermicompost of 3000 kg·ha-1). Compared with the TF treatment, biochar and vermicompost application alone or in combination increased the yield of fresh pod pepper by 24.38–50.03% and 31.61–88.92% in 2021 and 2022, respectively, whereas the yield of dry pod pepper increased by 14.69–40.63% and 21.44–73.29% in 2021 and 2022, respectively. The application of biochar and vermicompost reduced the nitrate content and increased the vitamin C (VC) and soluble sugar content of the fruits, which is beneficial for improving their quality. Biochar and vermicompost application alone or in combination not only increased nutrient uptake but also significantly improved agronomic efficiency (AE) and recovery efficiency (RE). In addition, although the application of biochar or vermicompost increased production costs, the increase in yield improved net income (ranging from 0.77 to 22.34% in 2021 and 8.82 to 59.96% in 2022), particularly in the TFBV2 treatment. In conclusion, the use of biochar and vermicompost amendments had a positive effect on the productivity and economic benefits of continuous pepper cropping, and the co-application of biochar and vermicompost could be an effective nutrient management strategy for the continuous cropping of pepper in the karst mountain areas of southwest China.
