Bio-based composite were used in NPK biodegradable fertilizers. The composition of fertilizers contains 0%, 5%, 10%, 15%, 20% starch from wood flour and the form of them were sticks. For the plant test there were used Petunia hybrid and Dyanthus caryophyllus in 8 cm diameter pots filled with 1:1 peat and garden soil. At every pot was used 0.5 g fertilizer stick. The biodegradable process of sticks determines the slow release of fertilizers in the pot. During vegetation period there were made some biometrical determinations (length, number of shoots) and agrochemical analysis at substrates and plants. Comparison between petunia and carnation development show that petunia answer better at fertilization process. From the point of view of experimental variants the best results were at variants with with 15% and 20% wood flour.
