Extreme climatic conditions and isolation from the rest of the world make it extremely challenging and difficult to obtain green vegetables in Kargil during the winters. Application of biochar enhances the productivity of vegetables during the short agricultural season so that the dry vegetable available throughout the winter. This research evaluates the potential use of biochar made from local apricot (Prunus armeniaca) seed shells (ASSBC) as a viable soil enhancer in the agriculturally difficult terrains of Kargil. Four vegetables that are relevant to the area selected for the investigations: spinach, lettuce, root beet, and mustard. Local veggie food security depends on these vegetables, especially around the winter when fresh green vegetables are unavailable. The shells of apricots, which were once considered trash, were collected, rinsed with distilled water, dried, crushed into uniform fragments, and then subjected to pyrolysis in nitrogen-laden conditions to form biochar. The obtained biochar was added to the soil kept in color coded experimental jars at a rate of 8%. The findings indicated that the number and size of leaves for spinach, lettuce, and mustard had significantly increased, while the length of the leaves for root beet has shown changes only in terms of the length of the leaves. Spinach, responde the most increasing leaf number from 07 to 45 without and with biochar respectively .Further evidence of the positive effects of biochar as a soil enhancer came from increases in soil pH, conductivity, and specific surface area following biochar addition. This research demonstrates how waste-to-best management may enhance soil quality, increase the production of vegetables grown nearby, and guarantee dried vegetable supply throughout the winter. The results show that using apricot shell biochar reduce adverse environmental impacts and improve yields from agriculture even in harsh conditions.
极端的气候条件以及与世界其他地区隔绝，使得在冬季的卡吉尔获取绿色蔬菜极具挑战性且困难重重。生物炭的应用提高了短农季蔬菜的产量，从而使冬季能有干菜供应。本研究评估了用当地杏（Prunus armeniaca）种壳制成的生物炭（ASSBC）作为卡吉尔农业困难地区可行的土壤改良剂的潜在用途。选取了与该地区相关的四种蔬菜进行调查：菠菜、生菜、根甜菜和芥菜。当地的蔬菜食品安全依赖于这些蔬菜，尤其是在冬季新鲜绿色蔬菜匮乏的时候。曾经被视为垃圾的杏壳被收集起来，用蒸馏水冲洗，干燥，粉碎成均匀的碎片，然后在充氮条件下进行热解以形成生物炭。将获得的生物炭以8%的比例添加到标有颜色编码的实验罐中的土壤中。研究结果表明，菠菜、生菜和芥菜的叶片数量和大小显著增加，而根甜菜叶片的长度仅在叶片长度方面有变化。菠菜在不添加和添加生物炭的情况下，叶片数量分别从7片增加到45片，增加最为显著。生物炭作为土壤改良剂的积极作用的进一步证据来自于添加生物炭后土壤pH值、电导率和比表面积的增加。这项研究表明了变废为宝的管理方式如何能够提高土壤质量、增加附近种植蔬菜的产量，并确保整个冬季的干菜供应。结果表明，即使在恶劣条件下，使用杏壳生物炭也能减少对环境的不利影响并提高农业产量。
