Despite several studies, role of eco-restoration strategies involving trees and grasses on soil organic carbon pools and fractions, response of soil enzymes in degraded land of tropical climate has remain largely overlooked. Four native fast growing fodder trees, namely, Ficus infectoria, Morus alba, Acacia nilotica and Leucaena leucocephala with combination of grasses viz., Cenchrus ciliaris, Chrysopogon fulvus and Panicum maximum were used as eco-restoration tool in Bundelkhand region. Total organic carbon (TOC), microbial biomass C (MBC), and activities of important soil enzymes were measured. After 9 years, land under Ficus, Morus, Acacia and Leucaena had ~63, 105, 87 and 81% greater TOC than fallow land in surface layer and Cenchrus, Panicum, and Chrysopogon increased TOC by 84, 91 and 77% at surface layers, respectively, over fallow land. MBC increased by 2–2.5 folds in both soil layers. All C fractions responded positively to eco-restoration. Ficus, Morus, Acacia and Leucaena boosted up carbon management index (CMI) by 51, 84, 71 and 65% at surface layers, respectively over fallow land. Similarly, grasses also improved CMI by >60%. Soil organic carbon accumulation under Ficus, Morus, Acacia and Leucaena were ~ 55, 91, 77 and 71% higher than fallow land at surface layers, and 71, 85, 95 and 69% higher than fallow land at subsurface soil layers. We developed an index for comparing ecorestoration efficiency (ERE). We found Morus + Panicum, Acaia + Panicum to be effective restoration strategies for eco-restoration under degraded lands of tropical climates. Our study indicated that implementation of these ecological restoration strategies could be a quantitatively important component of national climate change mitigation strategies in India and thus should be continually paid a great attention.

尽管进行了数项研究，但涉及树木和草类的生态修复策略在土壤有机碳库和馏分中的作用，热带气候退化土地上土壤酶的响应仍被很大程度上忽略。四个本地快速增长的饲料树，即榕infectoria，桑白皮，金合欢和银合欢用草组合即，水牛草，金须茅属茅和黍中被用作生态修复工具德尔肯德地区。测量了总有机碳（TOC），微生物生物量碳（MBC）和重要土壤酶的活性。9年后，与休耕地相比，榕树，桑属，相思树和白桦树的TOC分别高出耕地约63％，105％，87％和81％，而休耕地的Cenchrus，Panicum和Chrysopogon的TOC分别增加84％，91％和77％ 。在两个土壤层中，MBC均增加了2-2.5倍。所有碳组分均对生态修复反应良好。无花果，桑，相思和银合欢升压了碳管理指数（CMI）由51，84，71和65％在表面层，分别在休耕地。同样，草还使CMI提高了60％以上。干旱条件下土壤有机碳积累榕树，桑属，相思树和白桦树在表层分别比休耕地高约55、91、77和71％，在地下表层分别比休耕地高71、85、95和69％。我们开发了一个指数，用于比较生态修复效率（ERE）。我们发现桑属 +  Panicum，Acaia  +  Panicum是热带气候退化土地下生态恢复的有效恢复策略。我们的研究表明，实施这些生态恢复策略可能是印度国家减缓气候变化战略的数量上重要的组成部分，因此应继续予以高度重视。
