“…Our results showed, as the previously mentioned studies suggested, that CSBS had a different impact on the soil microbiome than the SS treatment ( Figure 4 ). CSBS elevated the abundance of Firmicutes, similar to the trend that was shown in other recent studies ( Achmon et al., 2020 ; Shea et al., 2022 ) ( Figure 4A ). This might suggest that the soil conditions developing in SBS are more anaerobic than those in SS treatment, a finding that was also previously reported ( Achmon et al., 2018 ).…”

“…Additionally, more emphasis was given in recent studies to the impact that SBS has on the soil microbial population (e.g. soil microbiome) ( Fernández-Bayo et al., 2019 ; Achmon et al., 2020 ; Shea et al., 2022 ). In these studies it was observed that SBS can alter the soil microbiome, mainly due to the combination of elevated quantity of organic matter, higher temperature and anaerobic conditions that serve as natural selective forces for an adaptive microbial community ( Achmon et al., 2020 ).…”

Soil biosolarization (SBS) is an alternative technique for soil pest control to standard techniques such as soil fumigation and soil solarization (SS). By using both solar heating and fermentation of organic amendments, faster and more effective control of soilborne pathogens can be achieved. A circular economy may be created by using the residues of a given crop as organic amendments to biosolarize fields that produce that crop, which is termed circular soil biosolarization (CSBS). In this study, CSBS was employed by biosolarizing soil with amended tomato pomace (TP) residues and examining its impact on tomato cropping under conditions of abiotic stresses, specifically high salinity and nitrogen deficiency. The results showed that in the absence of abiotic stress, CSBS can benefit plant physiological performance, growth and yield relative to SS. Moreover, CSBS significantly mitigated the impacts of abiotic stress conditions. The results also showed that CSBS impacted the soil microbiome and plant metabolome. Mycoplana and Kaistobacter genera were found to be positively correlated with benefits to tomato plants health under abiotic stress conditions. Conversely, the relative abundance of the orders RB41, MND1, and the family Ellin6075 and were negatively correlated with tomato plants health. Moreover, several metabolites were significantly affected in plants grown in SS- and CSBS-treated soils under abiotic stress conditions. The metabolite xylonic acid isomer was found to be significantly negatively correlated with tomato plants health performance across all treatments. These findings improve understanding of the interactions between CSBS, soil ecology, and crop physiology under abiotic stress conditions.

“…Moreover, the use of organic additives helps improve soil fertility and reduce chemical inputs [ 14 ], which is consistent with the ecological concepts of circular agriculture and sustainable development. This method is often used in greenhouse vegetable production, in combination with solar heating and soil flooding to enhance the control effect [ 26 ]. It is considered a practical, nonchemical approach to nematode disease management [ 27 ].…”

“…The type of organic amendment can boots certain microbial populations and lignocellulose degrading microorganisms induce antagonistic effects which exert pressure on the pathogen population, including Meloidogyne spp. (Simmons et al, 2016;Fernández-Bayo et al, 2019;Shea et al, 2022).…”

“…Most are free-living species with different feeding habits that occupy key positions in the soil food web (Bongers, 1990;Bongers and Ferris, 1999). Therefore, the study of the soil nematode community structure might be an indicator of changes in the microbial structure (Bongers and Ferris, 1999;Cesarz et al, 2015) and can be implemented in the evaluation of biodisinfestation treatments (Ney et al, 2019;Gandariasbeitia et al, 2021;Shea et al, 2022). Biodisinfestations suppose a transitional disturbance in the whole soil microbial community and change the soil physicochemical properties.…”

One of the major challenges in biodisinfestation treatments against soilborne pathogens is the selection of the proper organic amendments and mixture features. The use of agro-industrial by-products is a sustainable alternative with proven efficacy, but the availability has to be considered in terms of location and quantity. Sunflower seed is one of the five major oil crops widely cultivated and the husk constitutes a significant part that is discarded. This by-product brings together the features to be considered an interesting organic amendment in agricultural soils because of its lignocellulose content, but no references have been found in this field. In this study, sunflower seed husk was used with fresh cow manure in biodisinfestation treatments, alone or combined with other by-products (rapeseed cake, beer bagasse and wheat bran). The assay was performed in summer in a commercial greenhouse with significant yield losses in lettuce crops caused by the root-knot nematode Meloidogyne incognita. Four different amendment mixtures were applied which included 3kg/m2 cow manure, as common waste, and 1 kg/m2 of by-products (dry weight), considering 6mgC/g soil in all treatments but different C/N ratio (23, 29, 31, 34) and by-products. Data was collected in three moments: (i) before and (ii) after biodisinfestation treatments and (iii) after harvesting the first crop after biodisinfestations. Crop damage was assessed through root galling index and the number of eggs in roots. The effects on the pathogen population and the whole soil nematode community were assessed along with some physicochemical and soil microbiological variables (respiration rate, microbial organic C, water-soluble organic C and physiological profile of heterotrophic bacteria through Biolog Ecoplates™). All treatments reported effectiveness in disease control without significant differences among them, but among times. However, soil temperatures during biodisinfestations were higher at higher C/N ratios and fertility variables also increased in these cases, mainly in the treatment with husk as the only by-product. Sunflower seed husk proved to be an interesting source of organic C to improve both biodisinfestation treatments and soil fertility in humid temperate climate zones.
