Effect of organic and conventional farming practices on soil microbial population

Soil microbial and nutrient dynamics influenced by irrigation-induced salinity and sewage sludge incorporation in sandy – loam textured soil

“…The SS and water suspension ratios were assumed to be 1:5 in the case of the determination of pH and EC and thereafter, the standard methods were adopted (Richard, 1954). Digestion (with the di-acid mixture) is the main step followed thereafter, standard methods were adopted for analysis purposes (Antil et al, 2002).…”

“…Moist soil samples (0-15 cm) were collected plot-wise at the time of sowing, 35 DAS, and at harvest time for pearl millet, for wheat, at sowing, 75 DAS, and at harvest time over the course of the experiment and placed in the fridge. A chemical analysis of the soil samples for texture, pH, EC, organic carbon, available N, P, and K was completed using standard methods as outlined by Antil et al (2002). Microbial biomass carbon was determined by using the fumigation method (0.5 M K 2 SO 4 ) as described by Vance et al (1987).…”

Incidence of Drug-Resistant Enterobacteriaceae Strains in Organic and Conventional Watermelons Grown in Tennessee

“…Members of the Enterobacteriaceae family responsible for foodborne diseases, such as Klebsiella spp., Proteus spp., E. coli , and Salmonella, are found not only in human and animal gut microbiota but also in the soil [ 1 , 7 ]. Agricultural soils under organic management systems have been reported to have a significantly higher microbial diversity and count [ 8 ] when compared to conventional agricultural soils. While a rich soil microbial diversity is an indicator of good soil health, it also poses food safety concerns, as agricultural soil, irrigation water, manure, or grazing animals may be sources of contamination for fresh produce.…”
