Biochar and Nitrogen Fertilizer Promote Alfalfa Yield by Regulating Root Development, Osmoregulatory Substances and Improve Soil Physicochemical Properties

Agriculture, Journal Year: 2025, Volume and Issue: 15(3), P. 239 - 239

Published: Jan. 23, 2025

In artificial grassland systems, the extensive use of inorganic nitrogen (N) fertilizers has greatly enhanced yields but also caused significant environmental issues. The combined biochar and N fertilizer is recognized as an effective sustainable approach to reducing risks while boosting crop production. However, specific impacts on alfalfa yield, soil properties, root morphology remain unclear. This study examined effects three application rates (0, 10, 20 t hm−2) four levels 47, 94, 188 kg hm−2 yr−1) growth characteristics. Results revealed that notably promoted development increased osmoregulatory substance content. It biomass by improving nodule count, neck bud formation, diameter, reduced numbers. Biochar bulk density 0.8–10.5%, with further increasing available phosphorus potassium levels. Additionally, their significantly elevated nitrate ammonium concentrations. Overall, synergy enhances yield fostering better fertility.

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

Agronomy, Journal Year: 2023, Volume and Issue: 13(6), P. 1616 - 1616

Published: June 15, 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 and fertilizer on biological characteristics uptake pod peppers, well determine optimal ratio two-year field experiment was conducted southwest China. The results showed that, compared locally typical treatment (CF), combined application significantly increased yield both fresh dry pepper. Chemical reduction also ameliorated fruit quality, nutrient accumulation, improved utilization efficiency. What more, although employment made production costs higher, fertilizers increase economic efficiency, CF70B (70%CF + biochar). In conclusion, moderate amounts instead may be valid management strategy for pepper mountain areas, which beneficial maintaining stability, improving increasing net income.

Ameliorative Effects of Vermicompost Application on Yield, Fertilizer Utilization, and Economic Benefits of Continuous Cropping Pepper in Karst Areas of Southwest China

Agronomy, Journal Year: 2023, Volume and Issue: 13(6), P. 1591 - 1591

Published: June 13, 2023

In recent years, vermicompost (V) has been widely used as an amendment for improving crop productivity and soil quality. However, the ameliorative effect of on continuous cropping pepper remains unclear, particularly in karst areas southwestern China. A field experiment was conducted to study application yield, quality, nutrient accumulation, fertilizer utilization, economic benefits from 2021 2022. The included six treatments: CK (no fertilizer), FP (the fertilization practice local farmers), FPV (FP combined with 1500, 2250, 3000, 3750 kg·ha−1). results show that increased yield fresh pod by 28.34–51.36% (2021) 47.13–68.82% (2022), whereas dry 16.97–35.14% 34.48–62.61% respectively, compared treatment. reduced nitrate content vitamin C (VC) soluble sugar fruits, which is beneficial their Vermicompost not only uptake but also significantly improved agronomic efficiency (AE) recovery (RE). addition, although production costs, increase net incomes (16.02–31.83% 35.83–62.85% 2022), especially FPV4 conclusion, use had a positive pepper, may be effective management strategy mountain southwest
