“…The amount and equitability of carbon sources metabolized as indices of microbial richness and evenness, respectively, were used to calculate carbon source utilization profiles (CSUP), or functional diversity, of soil microbial assemblages (Wang et al, 2007;Habig and Swanepoel, 2015;Mofokeng et al, 2020).…”

The diversity of microbes in the soil of plants is important for sustainable agriculture as these microbes are important in carrying out different functional processes to improve the soil and invariably plant growth. Inversely the presence of the crop also affects the types of microbial communities in the soil. In this study, bambara groundnut was grown during the planting season in South Africa, from November to March 2014/2015 and 2015/2016 and soil samples were taken after every 4 weeks after planting. Soil samples were taken 15 cm deep from 2 different landraces named VBR and VL. Microbial diversity was determined by soil microbial Carbon Source Utilization Profiles (CSUP) using BIOLOG™ GN2 plates. The abundance and richness of the soil microbes was also determined using the Shannon-Weaver and Evenness diversity indices. The diversity of the soil microbial population changed over the stages of plant growth, according to cluster analysis. Bacterial abundance and diversity were higher at 4 and 8 weeks after planting (WAP). The microbial abundance (richness index) in this study ranged from 0.64 to 0.94 with cultivar VL2 at 8 WAP being the highest while bulk soil (control), R2 was the lowest. The Shannon-Weaver index varied between 2.19 and 4.00 with the lowest corresponding to control while the highest was VL2 at 8 WAP. Carbon sources utilized by bacterial communities spread across the 96 carbon sources. The highest utilization of carboxylic acids, ester, amino acids and polymers and carbohydrates was found in the bacterial communities of the different landraces across growth stages. The highest utilization of alcohols, amides, amines, aromatic chemicals, brominated chemicals and phosphorylated chemicals was found in the control landraces. This indicates that the soil samples between 4 WAP and 12 WAP were richer in diversity of microbial species and their abundance. This soil diversity and richness is an indicator of the quality of the soil in order to increase crop yields and agricultural production.

“…However, improved soil fertility and increased food production was achieved through the application of bioslurry on cultivated loamy soils (Zuma, 2015). Mofokeng et al (2020) also reported that bioslurry could be used as organic amendment to sandy soils, due to its positive effects on health and fertility. Although chemical fertilizers have readily available and large quantities of plant nutrients compared to organic fertilizers, the fact that organic fertilizers have growth-promoting agents makes them important for the enhancement of soil fertility and productivity (Sanwal et al, 2007;Adeleye et al, 2010).…”

Swiss chard is amongst the widely cultivated green leafy vegetables that play a significant role in alleviation of food insecurity and malnutrition in South Africa. Greenhouse experiments were conducted to evaluate the effect of Bioslurry effluent on growth, biological yield and nutrient content of Swiss chard. Two cultivars of Swiss chard (Fordhook giant and Star 1801) were planted in 10 plots of 4.5 m² using sand incorporated with different rates of Bioslurry (Bio), namely, control (no fertiliser incorporation), 50% Bio, 100% Bio, 200% Bio and the recommended rate of 2:3:4 (30) NPK fertilizer as a growing medium. One seedling was planted per hill at an intra and inter row spacing of 0.25 m x 0.5 m. At 20-day intervals, five randomly selected plants were sampled to measure growth and yield parameters until 60 days after transplanting. The results showed that fertiliser treatment and cultivar significantly (p<0.05) influenced growth and yield parameters of Swiss chard. Fordhook giant showed significantly (p<0.05) higher growth and yields in all sampling intervals in summer compared to Star 1801. Inconsistencies were observed on leaf nutrient elements; however, NPK showed relatively higher nutrient elements for macro-elements.
