“…Combined with the ecological indices BI, which is related to soil properties and decomposition pathways 24 , we found that higher CI value for the three straw mulching treatments appeared in the whole-plot coverage treatments ( all n ). Our results contrast with those of other studies, which found that bacterial-dominated decomposition pathways were the most common pathways 20 .…”

Agricultural management techniques such as mulching with crop straw can impact soil properties and may in turn change the structure and function of the soil food web. We investigated different straw mulching types and straw mulching coverage levels on soil nematodes community structure in walnut orchards. We set up a randomized experimental design with three straw mulch types, and three straw mulch distance treatments in a walnut plantation. The results indicated that the number of soil nematodes after straw mulching was lower than that found in the control (CK). However, the metabolic and structure footprints of the omnivore-predator nematodes showed higher values as compared to CK. The abundances of plant parasite and omnivore-predator nematodes were negatively correlated with ammonium nitrogen (NH4+–N) and dissolved organic nitrogen (DON), whereas soil moisture content (SM) had a negative correlation with the abundance of total nematodes. High structure index (SI), maturity index (MI) and low enrichment index (EI) values revealed a structured soil food web, medium soil enrichment, and fungal decomposition channel under the mix straw mulching treatments. Soil nematodes should be used as an indicator of soil functional changes resulting from straw mulching.

“…juveniles per 50 g of roots of susceptible sugarcane varieties (Dinardo-Miranda et al 1996;Novaretti 1997). However, sand soils under environmental stress from water deficits are more affected by plant-parasitic nematodes (Li et al 2014;Lu et al 2016;Vicente et al 2016), disrupting the soil's natural balance and food web (Sohlenius et al 2011;Cardoso et al 2016).…”

“…Ranking changes of recorded taxa at harvest, in contrast to renovation period, agree with Vicente et al (2016), who has also recorded an increase of population density of Pratylenchus, Trichodorus, and Xiphinema nine months after planting and at harvest, though these genera have been dominating the area during all sampling periods along with the family Criconematidae. The dominance of plant-parasitic nematodes is commonly observed in monoculture (Lu et al 2016).…”

Edaphic climatic conditions directly affect the population dynamics of nematode assemblages and management strategies. The objective of this study was to characterize spatiotemporal changes in nematode abundance and diversity in sugarcane fields of northeastern Brazil under different edaphic climatic conditions. Soil samples from seven geoenvironmental sites under continuous cultivation were taken at planting and 4, 9, and 14 months after planting. Nematode abundance and diversity varied with the soil's physical and chemical characteristics. Sites in the rainfed and irrigated coastal tables as well the floodplain had higher number of nematodes in contrast to the flat-land and hillside. The abundance of plant-parasitic nematodes increased concurrently with crop development, but the number of taxa decreased. Meloidogyne and Pratylenchus were the dominant plant-parasitic genera across locations, but bacterivores were dominant in southern sites at field replanting. Heat map delineated two distinct groups of nematode distribution within the geoenvironmental zones, rather than the sampling times. Pratylenchus density was high in both groups, but in contrast with Meloidogyne and Criconemella, the abundance of Pratylenchus and Helicotylenchus was higher in sites with lower soil bulk density and higher porosity, clay, organic matter, and water contents as those in the southern sites, reflecting edaphic climatic conditions.

“…Early research on farmland ecosystem service value mainly focused on the provisioning service, as well as the quality and yield of agricultural products, while it did not fully recognize the regulating service, supporting service and cultural service (Porter et al, 2009;van den Belt and Blake, 2014), or the impact of land use and farmland abandonment on the farmland ecosystem services value (Lin et al, 2018;Sil et al, 2019). Some practical techniques for the quantitative assessment of farmland ecosystem services have been developed to meet the requirements of different end users (Tzilivakis et al, 2019), and the loss of farmland ecosystem services value caused by the negative environmental impact of agricultural production activities needs to be strengthened (Lu et al, 2016). Because the farmland ecosystem is greatly affected by human activities, it is difficult to measure the value of farmland ecosystem services, especially its non-market value (Yang et al, 2005;Du et al, 2008).…”
