The document discusses the effects of applying a biological fertilizer called BIO P 2000 Z to acidic and pyritic soils over a period of 10 weeks. Within 3-5 weeks, the soils developed complex associations of microorganisms and the pH increased to 5.5. By 10 weeks, plants were able to grow in the soil which now had a pH of 5.5-6. Soil properties including organic carbon, total nitrogen, C/N ratio, and various mineral contents improved after applying the biological fertilizer during the composting process.
