Effect of increasing rates of organic fertilizers on the soil microflora (pot experiment with maize)
Dimka Ivanova, Jonita Perfanova, Zdravka Petkova
Abstract: The present study was carried out with Leached Vertisol at a pot experiment, to assess the impact of increasing fertilization rates of organic fertilizers on the growth and spreading of major groups of soil microorganisms in the rhizosphere zone of maize (Zea mays L.). The obtained results showed that Humipromoter and Biopromoter have a positive еffect on the numbers of the soil microflora, which is observed to a varying extent depending on the applied fertilization rates.
