The present study aimed to monitor the germination percentage of radishes and spinach in compost mass in pure form and with additives. Six variants and one control (V0) were prepared: V1 - lavender extract, V2 - thyme extract, V3 - basil extract, V4 - mix, V5 - microbial fertilizer, V6 - mineral fertilizer, V7 - Min. + microbial fertilizer for each of the studied crops - a total of 14 samples. An initial reading of the microbial community was carried out after the introduction of the additives and immediately before planting the seeds and then at day 5, day 10 and day 15. The temperature, humidity and pH of the samples were measured. The two considered crops give different germination percentages of the different variants. Spinach seeds generally had difficulty germinating and produced fewer sprouts than radishes. The best results for germination and survival of the sprouts were obtained for the spinach in the control and in the variant with mineral fertilizer and the variant with basil. For the radishes, the best germination was shown by the control and by the variants with microbial fertilizer, the variant with microbial and mineral fertilizer.
