Influence of Organomineral Fertiliser from Sewage Sludge on Soil Microbiome and Physiological Parameters of Maize (Zea mays L.)

The use of a soil fertiliser results in high, good quality yields. most widely used fertilisers are mineral or organic, but there is increasing attention on organomineral produced from sewage sludge. These contain beneficial components which may improve fertility and thus plant productivity, some concerns associated with their application due to composition. Using short-term pot experiment the effect such conditioner called FS, sludge after stabilisation lime, qualitative−quantitative composition activity microorganisms selected physiological parameters maize was analysed. study carried out completely randomised design, including control (soil + lime NPK). FS had positive pH, equivalent lime.
