摘要

充足施肥是作物可持续生产的首要前提。纳米肥料被认为是新型肥料,这些肥料的开发和测试一直是令人兴奋的研究领域。在此,我们通过化学方法开发了基于纳米生物炭的氮肥和钾肥,并在花生(Arachis hypogaea L.)上对制备的肥料进行了测试,以评估其生物功效。采用适当的技术对基于纳米生物炭的氮肥(NB-N)和钾肥(NB-K)进行了表征,包括动态光散射粒度分析(NB-N(20.3 nm);NB-K(18 nm))和 zeta 电位测量(NB-N(33.2 mV);NB-K(-33.4 mV))、傅立叶变换红外光谱(FT-IR)、X 射线衍射(XRD)和扫描电子显微镜(SEM)。与推荐的肥料剂量(分别为 23.70 克/株和 27.30 克/株)相比,50% N+50% NB-N+100% P+100% K 的土壤施肥与商业肥料配合使用,花生的豆荚产量(25.38%)和茎秆产量(34.42%)显著提高。此外,与建议施肥量相比,NB-N 和 NB-K 肥料能显著提高株高(17%)、根瘤(41%)、叶绿素含量(19%)和干物质产量(34%)。与建议施肥量(分别为 2.20%、0.63% 和 1.45%)相比,相同处理的氮磷钾含量更高(分别为 14.39%、49.21% 和 33.33%)。总之,这项研究表明,纳米生物炭肥料具有提高作物产量和土壤肥力的潜力,同时也证明了在土壤中施用纳米生物炭肥料可促进可持续农业实践。

Effects of Soil Application of Nanobiochar-Based Nitrogen and Potassium Fertilizers on the Growth and Yield of Groundnut (Arachis Hypogaea L.)

Effects of Soil Application of Nanobiochar-Based Nitrogen and Potassium Fertilizers on the Growth and Yield of Groundnut (Arachis Hypogaea L.)

Adequate fertilization is the primary pre-requisite for sustainable crop production. Nanofertilizers are considered as new class of fertilizers and development and testing of these fertilizers are been an exciting research areas. Herein, we developed nanobiochar based nitrogen and potassium fertilizers through chemical methods and as prepared fertilizers were tested on groundnut (Arachis hypogaea L.) to evaluate their bio-efficacy. The nanobiochar-based nitrogen (NB-N) and potassium (NB-K) fertilizers were characterized by employing appropriate techniques, including dynamic light scattering for particle size analysis (NB-N (20.3 nm); NB-K (18 nm)) and zeta potential measurements (NB-N (33.2 mV); NB-K (-33.4 mV)), Fourier Transform Infrared (FT-IR) spectroscopy, X-Ray Diffraction (XRD) and Scanning electron microscopy (SEM). Upon soil application in conjunction with the commercial fertilizers, the treatment 50% N + 50% NB-N + 100% P + 100% K recorded significantly higher pod yield (25.38%) and haulm yield (34.42%) compared to recommended dose of fertilizers(23.70 and 27.30 g/plant respectively) in groundnut. Further, NB-N and NB-K fertilizers significantly improved plant height (17%), root nodules (41%), chlorophyll content (19%) and dry matter production (34%) when compared to the recommended dose of fertilizers application. Higher nitrogen, phosphorus and potassium contents (14.39%, 49.21% and 33.33% respectively) were recorded with the same treatment compared to recommended dose of fertilizers (2.20, 0.63 and 1.45% respectively). Overall, the study shows that nanobiochar-based fertilizers have the potential to enhance crop productivity and soil fertility and also demonstrated the soil application of nanobiochar based fertilizers for sustainable agricultural practices.

期刊介绍: The Journal of Soil Science and Plant Nutrition is an international, peer reviewed journal devoted to publishing original research findings in the areas of soil science, plant nutrition, agriculture and environmental science. Soil sciences submissions may cover physics, chemistry, biology, microbiology, mineralogy, ecology, pedology, soil classification and amelioration. Plant nutrition and agriculture submissions may include plant production, physiology and metabolism of plants, plant ecology, diversity and sustainability of agricultural systems, organic and inorganic fertilization in relation to their impact on yields, quality of plants and ecological systems, and agroecosystems studies. Submissions covering soil degradation, environmental pollution, nature conservation, and environmental protection are also welcome. The journal considers for publication original research articles, technical notes, short communication, and reviews (both voluntary and by invitation), and letters to the editor.
