“…These are responsible for converting nutrients into forms available to plants. This is confirmed by previous studies on enzyme activity conducted by Furtak and Gajda [63] and Sheoran et al [64]. The CV analysis for the two soil-use systems ranked the enzymes as follows: for CF soils: AlP > AcP > CAT > DEH; and for OF soils: AlP > CAT > AcP > DEH, showing that alkaline phosphatase was the most sensitive to the cultivation treatments used.…”

The chemical properties and enzymatic activity of the surface soil horizon were compared between an organic farm (OF) (crop rotation with legume plants, fertilisation with manure) and a conventional farm (CF) (simplified crop rotation, mineral fertilisation, chemical crop protection products). In the years 2001-2017 on the OF (near the village of Juchowo, northern Poland), a reduced tillage system (ploughless) was used, while plough cultivation was used on a CF located in its immediate vicinity. The parameters used to assess the properties of soils were: particle size composition, pH, total organic carbon (TOC) and total nitrogen (TN), dissolved organic carbon (DOC) and dissolved organic nitrogen (DON). The activity of dehydrogenases (DEH), catalase (CAT), alkaline phosphatase (AlP) and acid phosphatase (AcP) and the content of easily extractable glomalin-related soil protein (EEGRSP) were also determined. Sixteen years of soil use in accordance with ecological principles significantly increased the average content of TOC, NT, DOC and DON. Soil samples rich in TOC and DOC showed significantly higher DEH and AcP activity, and EEGRSP content. Statistical analysis showed that the activity of DEH, AlP and CAT in the soil was significantly higher for the OF than for the conventional cultivation system. Limiting soil cultivation procedures on the OF improved the balance of soil organic matter (SOM) and pH value, and significantly increased the content of EEGRSP as compared to the cultivation system used on the CF.

“…In addition, it should be noted that certain fungi (Bipolaris, Acremonium, Mucor, Fusarium) were found only on organic fruit. Considering the above, along with the observations and results of other authors 22 it can be assumed that the cultivation system (organic or conventional) had a significant impact on fungi. The cultivation system significantly affected the number of yeasts and moulds as well as the taxonomic composition of fungi.…”

“…Both types of fruit may pose a threat to the consumer: fruits from conventional crops may have pesticide residues, and fruits from organic farms may contain mycotoxins 12,25 . A well-known thesis was confirmed that the use of pesticides and synthetic fertilizers (strong interference with natural plant growth) changes the plant microbiome 22,23 . The same cultivar of blueberries, cultivated on the same soil, but in a different way, differed in the composition of fungi.…”

The aim of this study was to compare the nutritional and use value of berries grown in organic and conventional systems. The polyphenol content, fruit colour and firmness, and yeast, mould, and mycotoxin contents were assessed in blueberry fruit freshly harvested and stored for 8 weeks in controlled conditions (CA: CO2-12%; O2-1.5%, temperature 1.5 °C). The Shannon–Wiener diversity index was comparable in both systems and was lower for mould in organic fruit than in conventional fruit. Mycotoxins (deoxynivalenol, zearalenone) were found only in organic fruits. The optimal mineral content and pH of the soil allowed the cultivation of blueberry in accordance with organic standards. The storage of highbush blueberry fruit in CA cold storage for 8 weeks resulted in a slight deterioration in fruit quality and polyphenol content. The lower nutritional value of these fruits is compensated by the lack of pesticides and artificial fertilizers residues. The use of fungicides in conventional cultivation reduces the population of sensitive fungi and therefore reduces the contamination of fruits with mycotoxins.

“…It also indicates that organic soils have higher rate of biological oxidation due to higher microbial activity [16]. The presence of larger quantities of organic substrates enhanced the microbial activity to produce enzymes [39] and also the increase in the release of root exudates by the crops stimulated the microbial growth [40].…”

Aims: Assessing various soil properties as influenced by organic farming in the selected certified organic and conventional farms of Kerala. Study Design: Ten pairs of certified organic farms and nearby conventional farms were identified from different agroecological zones of Kerala and were analysed for physical, chemical and biological properties. Place and Duration of Study: The research was conducted at College of Agriculture Vellayani, between December 2020 – June 2021. Methodology: Soil samples were collected from these farms and analyzed for soil physical, chemical and biological properties, organic carbon, total nitrogen, C: N ratio and organic matter fractions. Results: Organic farms exhibited lower bulk density (1.15 Mg m-3) and higher values in porosity (41.32%), water holding capacity (52.68%), mean weight diameter (1.87%), and water stable aggregates (73.59%) compared to conventional farms. Additionally, organic farms were found to be higher in electrical conductivity (0.09 dS m-1), cation exchange capacity (5.98 C mol(p+) kg-1), total organic carbon (7.59%), total nitrogen (0.46%), and C:N ratio (16.14) in comparison to conventional farms. The concentrations of fulvic acid, humic acid, and humin are also greater in organic farms, with mean values of 5.45%, 3.56%, and 0.47%, respectively. Conclusion: Organic farming has a significant role in improving the physical, chemical and biological properties of the soil and also total carbon, total nitrogen and the organic matter fractions.
