“…Furthermore, bacterial diversity is an important part of soil biodiversity; when bacterial diversity increases, soil biodiversity increases as well. In general, soil biodiversity has a positive correlation with the productivity and sustainability of a system (Hunt & Wall, 2002), and it is sensitive to changes in land management practices, such as cropping systems, tillage, and fertilization (Roy et al, 2018). As a traditional soil management practice under the long-term monocropping of lily in this region, constant organic fertilizer inputs play an important role in preventing soil degradation by preventing bacterial diversity loss during its perennial cropping.…”

“…Maintaining high agricultural production on a sustainable basis requires conservation of natural resources, including maintenance of soil quality. Recently, global interest in improving soil quality and adoption of sustainable land management systems, including farming systems, has been growing (Roy, Roy, Jaiswal, & Baitha, 2018). Crop replanting refers to the practice of cultivating the same crop in soils that had previously supported the same or similar plant species year after year.…”

Bacterial communities as indicators of soil health under a continuous cropping system

With growing global interest in the improvement of soil quality and the adoption of sustainable land management systems, there is an urgent need to find early indicators to monitor and manage sustainable soil health. Meta‐analyses provide useful information on microbial communities and community‐level molecular characteristics, which can be exploited as ‘biomarker’ indicators of ecosystem processes for soil health evaluation. Lanzhou lily (Lilium davidii var. unicolor) is the only type of sweet edible lily in China, as well as an endemic species with a narrow distribution. Due to its uses as food and in gardening, this lily has an economic value in the Country, particularly in Gansu Province located in the Loess Plateau. This lily is usually cultivated in long‐term continuous monoculture (replanting), resulting in the so‐called consecutive replanting problem (CRP), which is associated with severe soil degradation and significant yield and quality losses. This study was conducted to investigate the bacterial community structure and specific bacterial members related to the lily's CRPs and soil health degradation indicators via next‐generation sequence (NGS) analysis. The bacterial diversity of rhizosphere soil was analyzed by high‐throughput DNA sequencing (Miseq) of samples collected in fields at 0, 3, 6, and 9 replanting years (L0, L3, L6, and L9, respectively). Results showed that long‐term replanting significantly increased soil bacterial abundance and insignificantly changed soil bacterial diversity. However, replanting altered the soil microbial communities where 3–6 years of replanting was a transmission period for change, resulting in a new community structure after 9 years of replanting. Some specific bacterial members were found to be correlated with lily's plant growth, both positively and negatively. Long‐term replanting accumulation of the harbored highly abundant pathogenic bacterial genus Streptomyces and the species Bacillus simplex and depletion of the plant‐beneficial bacteria genera Sphingomonas and Hyphomicrobium are the causes of the lily's CRP under a 0–9 year replanting system. In addition, changes in the soil physiochemical properties contributed to the new structure of bacterial communities, and the phylum Proteobacteria and the genus Sphingomonas could be regarded as potential indicators of sustainable soil management.

“…In nature, soil biodiversity has a positive correlation with the productivity and sustainability of a system (Hunt and Wall, 2002), and loss and simplification of soil community composition impair multiple ecosystem functions, including plant diversity, decomposition, nutrient retention, and nutrient cycling (Wagg et al, 2014). Soil biodiversity is sensitive to changes in land management practices, such as cropping systems, tillage and fertilization (Roy et al, 2018).…”

Soil Fungal Diversity Loss and Appearance of Specific Fungal Pathogenic Communities Associated With the Consecutive Replant Problem (CRP) in Lily

et al. 2020

Edible lily (Lilium davidii var. unicolor) has economic value in China, particularly in Gansu Province, due to its uses as food and in gardening. Edible lily is usually cultivated in a long-term continuous monoculture resulting in the so-called consecutive replant problem (CRP), which is associated with severe soil degradation and significant yield and quality losses. This study was conducted to investigate the fungal community structure and specific fungal members related to lily's CRPs using metabarcoding analysis. Fungal diversity of rhizosphere soil was analyzed by high-throughput DNA sequencing (Miseq) of samples collected in fields at 0, 3, 6, and 9 replant years (L0, L3, L6, and L9, respectively). The results show that long-term replanting significantly decreased both soil fungal diversity and abundance at the OTUs levels. Furthermore, replanting altered the soil microbial communities, where 4 to 5 years of replanting is a key transition period for substantial change of fungal community structure, resulting in new fungal community structures in L6 and L9 compared to in L0 and L3. The fungal diversity loss and fungal community structure simplification contributes to the negative effect of replanting in lily, and after 6 years of replanting, accumulation of highly abundant pathogenic fungal genera and depletion of the putative plant-beneficial fungal genera exacerbate the lily CRP. In addition, changes in the soil physiochemical properties strongly contributes to the new structure of fungal communities, and the genera Cryptococcus and Guehomyces could be regarded as potential indicators to monitor and manage sustainable soil health in the lily cropping system.

“…By contrast, the organisms associated with the soil use systems with natural vegetation (preserved cerrado and disturbed cerrado) are correlated with the organisms (Thysanura, Araneae and Isoptera), which are related to different plant and soil strata. The Isoptera group is comprised of organisms which are fundamentally important for nutrient cycling and soil aeration (ROY et al, 2018).…”

Diversity of Edaphic Fauna in Different Soil Occupation Systems

et al. 2019

Soil is the habitat for a number of living organisms that perform essential functions within the ecosystem; their functions and interactions are modified according to different ways of land occupation. Thus, the objective of this study was to evaluate the diversity of edaphic fauna in different soil occupation systems. The study was carried out in different soil occupation systems: millet, maize, soybean, eucalyptus, preserved cerrado, disturbed cerrado, and pasture, with 130 pitfall traps installed per treatment. Soil fauna organisms were identified at the level of large groups (orders and family), and then examined under the following biological diversity indices: Shannon index, Pielou index, average and total richness, and abundance. The highest abundance was found under millet growing conditions (9,974 individuals), and the lowest abundance values were found in soybean soil (222 individuals) and maize (824 individuals). Uniform distribution of groups in the area with soybean crops, due to the homogeneous management of the area, provided the highest biological index (H'=2.69). Principal component analysis (PCA) explained 50.9% of the data along the main axis and 34.6% of the data along the secondary axis. The different systems of soil occupation showed different abundance and diversity, demonstrating how soil occupation interferes with the dynamics of the invertebrate soil fauna.
