“…Our previous study has found that the comprehensive assessment indices based on fourteen soil physical and chemical properties of rubber plantations were significantly lower than those of tropical rainforests on Hainan Island (Sun et al, 2021). Similarly, as in Xishuangbanna (southwest China) the soil quality index value based on 23 soil physical and chemical properties of the rubber plantation decreased by 15.50%, compared to the primary rainforest (Zou et al, 2021). The previous studies also found that chemical properties contributed more to the soil quality index than the physical properties (Sun et al, 2021;Zou et al, 2021), with the biological properties were rarely considered.…”

“…Particularly, land-use changes can influence soil degradation (Vityakon, 2007;Nabiollahi et al, 2018;Nosrati and Collins, 2019), soil physical and chemical quality (Deng et al, 2016;Liu et al, 2018;Wang et al, 2019;Sun et al, 2021), soil biological quality (Berkelmann et al, 2018;Cai et al, 2018) Sun et al, 2021), soil nutrients and fertility (Chiti et al, 2014;De Blécourt et al, 2014;Guillaume et al, 2015;Allen et al, 2015;Hassler et al, 2017;Maranguit et al, 2017), soil respiration (Goldberg et al, 2017;Zhao et al, 2018), and soil microbial communities (Krashevska et al, 2015;Kerfahi et al, 2016;Wang et al, 2017;Berkelmann et al, 2018;Lan et al, 2017a;. A soil quality index was also established based on soil's physical and chemical properties to comprehensively assess the effects of rubber plantations on the soil after being converted from tropical rainforest (Sun et al, 2021;Zou et al, 2021).

“…CC BY 4.0 License.Comparing various SQI between studies is complex and partly impossible because of the diverse soil properties and weighting factors(Kuzyakov et al, 2020).Hence, a radar diagram was applied to show each of the soil properties and soil function changes. It was found that most of the soil properties and functions decreased by the conversion of tropical rainforests to rubber plantations on Hainan Island.Taking into account that the soil quality would significantly decrease from high to low plant diversity on rubber plantations(Hemati et al, 2020), interplanting (Liu et al, 2018a Chen et al, 2019; Sun et al, 2021;Zou et al, 2021) and natural management(Lan et al, 2017a) were considered as alternative mechanisms to improve soil quality on monoculture rubber plantations.…”

Abstract. Land-use changes can alter soil properties and thus affect soil quality. Our understanding of how forest conversion (from tropical rainforest to rubber plantations) affects soil properties and soil quality is limited. An ideal testing ground for analyzing such land-use change and its impacts is Hainan Island, the largest tropical island in China. Based on 21 soil physicochemical and biological properties, a soil quality index (SQI) employed principal component analysis to assess soil quality changes from the conversion of tropical rainforests to rubber plantations. The results showed that (i) soil available potassium, available phosphorus, microbial biomass carbon, cellulose decomposition, acid phosphatase, and urease were vital soil properties for soil quality assessment on Hainan Island. (ii) The SQI of rubber plantations decreased by 26.48 % compared to tropical rainforests, while four investigated soil properties (soil pH, total phosphorus, cellulose decomposition, and actinomyces) increased. (iii) The SQI of both the tropical rainforests and rubber plantations showed significant spatial differences, which, under tropical rainforests, was more sensitive to seasonal changes than those under rubber plantations. (iv) Structural equation modeling suggested that forest conversion directly impacted soil quality and, indirectly impacted soil qualities' spatial variation by their interaction with soil types and geographical positions. Overall, though the conversion of tropical rainforest to rubber plantation did not decrease all soil properties, the tropical rainforest with its high soil quality should be protected.

Tectona grandis L.f. mediated restoration of marginal lands in Eastern Uttar Pradesh, North India

Tectona grandis L.f. has considerable potential to restore marginal and degraded lands as it offers multiple co-benefits during the restoration venture. It provides good quality wood for multipurpose use, including biomass for bioenergy and noninvasive traits. For this, aboveground biomass (AGB) was assessed along with testing the critical soil properties (soil physicochemical and biological properties) across different plantation sites during a 4-year study period (2015)(2016)(2017)(2018). The study suggested that the soil properties like bulk density, moisture content, pH, organic carbon, available nitrogen, phosphorus, and potassium have shown significant mean improvement in all planted sites collectively. These were improved by À0.21 g cm À3 , 0.68%, À0.68, 0.27%, 13.69 mg kg À1 , 11.77 mg kg À1 , 95.20 mg kg À1 , respectively, in an arid area (Mirzapur, i.e., M1, M2, M3, M4, M5, and M6 sites, representing a warm and tropical dry climate) from the unplanted control (CM1) during 2015-2018. Moreover, the microbial biomass carbon and dehydrogenase activity were significantly improved by 56.71 mg kg À1 and 6.92 μg TPF g À1 hr À1 , respectively, from CM1. Similar results were also observed in the semiarid areas of Varanasi, representing a humid subtropical climatic pattern (i.e., V4 and V5 sites) compared to the unplanted control in the (CV1). Furthermore, the AGB was found between 12.56 and 229.13 kg tree À1 , representing 5 and 30 years of plantation, respectively, in 2018. Reference sites (V1, V2,

Soil quality is a critically important component of soil within ecosystems, and our understanding of soil quality variation and its driving factors in tropical forests is limited. This study collected soil samples at 0-20 cm depths from two typical tropical forests (tropical rainforest and rubber plantation) on Hainan Island, China's largest tropical island, during dry and rainy seasons. A soil quality index (SQI) using principal component analysis was applied to measure soil quality based on 21 soil properties.The soil properties' spatial and seasonal changes and their driving factors were simultaneously collected for a holistic analysis of the ecosystems. The results were summarized as follows: (i) The SQI of the rubber plantation decreased by 26.48% compared to the tropical rainforest on the island, while four soil properties investigated (soil pH, total phosphorus, cellulose decomposition, and actinomycetes) increased. (ii) The SQI of different soil types in the two tropical forests displayed an apparent discrepancy. Within the same soil type, the SQI of tropical rainforests showed no obvious differences, while there was a notable spatial discrepancy among rubber plantations in dispersed geographical positions belonging to varied climatic zones. (iii) The SQI of the tropical rainforest was significantly higher in the wet season than in the dry season. In contrast, there were no significant differences between the two seasons for rubber plantations, indicating that soil quality in the tropical rainforest was more sensitive to seasonal changes than soil quality in rubber plantations.Overall, we concluded that except for land use and soil type, spatial variability and seasonal pattern also played essential roles in soil quality on the tropical island. The results from the SQI are expected to provide novel information regarding the sustainable use of tropical forests on Hainan Island.
