“…In addition to stand age, we implemented four treatments involving the use of organic residues (compost, mulching, and a combination of both), testing how these residues alter soil chemical properties and soil quality in two orchards with different ages and characteristics. Stand age, based on habitat provision, exhibited specific influences on the abundance of soil biota and functional groups, while organic residue management demonstrated specific impacts on biodiversity indices, soil chemical properties, and soil quality in an Acrisol under field conditions (Rodriguez‐Ramos et al., 2022; Santolamazza‐Carbone et al., 2023). We anticipated a strong correlation between soil quality and the following characteristics: (i) the 9‐year‐old stand, characterized by its dynamics and inherent traits, such as higher biomass production and yield compared with the 16‐year‐old stand (da Silva, Souza, Laurindo, Nascimento, et al., 2022); (ii) high root activity in a young stand (Nascimento et al., 2021); (iii) a perennial life cycle with a high rate of nutrient cycling (da Silva, Souza, Laurindo, Freitas, et al., 2022); and (iv) a low soil organic matter decay rate in soils with high inputs of organic residues, such as compost and compost + mulching (Gondim et al., 2023; Melo et al., 2019).…”

Pyrus pyrifolia is a common temperate fruit crop cultivated in Southern Brazil for fruit production. Although this plant species is found in several Brazilian states (Paraná, Santa Catarina, São Paulo, Rio Grande do Sul), it is predominantly concentrated in the smallholder farming system in Santa Catarina, Brazil. Our aim was to compare the soil biota community composition, soil chemical properties, and soil quality in two adjacent stands with different ages. Within each stand, we analysed the influence of four organic residue management practices. Our results indicated that both studied stands, influenced by different organic residue management practices, exhibited differences in soil biota community composition, soil chemical properties, and soil quality. Acaridae, Araneidae, Blattidae, Halictophagidae, and Opiliones were the main contributors, explaining 78.08% of the variance in the data. The 16‐year‐old stand, with compost utilization, displayed a high biodiversity of soil organisms, average soil chemical properties, and the highest values of soil quality, creating a habitat for predators and providing energy for litter transformers and ecosystem engineers in subtropical Acrisol. These findings contribute to a deeper understanding of the influence of old stands on soil biota community composition, soil chemical properties, ecosystem homeostasis, herbivory pressure, and prey‐predation relationships. This, in turn, may enhance interest in establishing new management plans for Pyrus pyrifolia stands in commercial orchards.

The main objective of this study was to determine the possible interaction of two important abiotic factors (soil and climate) on the mycelial concentration and frequency of the ectomycorrhizal fungi Boletus edulis and B. reticulatus, using traditional statistics and artificial neural network tools. The frequency and concentration of Boletus mycelium were determined over three months (September, October, and November), and two years (2018 and 2020), in three hybrid chestnuts (Castanea × coudercii) orchards of 40-, 10-, and 3- years-old, using real-time qPCR. Statistical analysis revealed a significant effect of the year on B. edulis mycelium concentration and of the sampling plot (different tree ages) on B. reticulatus frequency. The combination of artificial intelligence networks (ANN) with fuzzy logic, named neurofuzzy logic (NF), allowed the construction of two robust models. In the first, using year, month, and sampling plot as inputs, NF identified hidden interactions between year and month on B. edulis mycelium concentration and between sampling plot and sampling month on B. reticulatus mycelium frequency, thus improving the information obtained from the statistical analysis. In the second model, those three factors were disaggregated into 44 inputs, including 20 soil properties and 24 climatic factors, being NF able to select only 8 as critical factors to explain the variability found in both ectomycorrhizal Boletus species regarding mycelial frequency and concentration. Specifically, NF selected two chemical soil properties (cation exchange capacity and total carbon) and three physical properties (macroaggregates, total porosity, and soil moisture at field capacity), as well as their interactions with three climatic elements (cumulative difference between precipitation and potential evapotranspiration (P-PET-1-2) and water deficit (WD-1-2) in the previous two months and excess water (WE-1) in the month prior to sampling. These results provide a much deeper understanding and new insights into the ecology and the role of abiotic factors which explain the different mycelial development patterns of ectomycorrhizal fungi such as B. edulis and B. reticulatus in chestnut agroecosystems.
