The investigations on new manure substances and substances which improve the pH and the structure of the soils are very important for improving of the agro-ecological condition of the soils, vegetable yield increasing, economization of raw materials and no to a least point for utilization of some types of wastes like a secondary raw materials in the agriculture. The presented in the current article data are continuation of done investigation over the efficiency of new mixtures for soil conditioners, which are produced on the base of wood ash and additional substances and wastes. Here are generalized the results from done pot-tests, which show the advisability of using of these soil conditioners at cultivation of sweet pepper (Capsicum annum L.) variety Sofiiska kapia. Based on the results it is proved that in the practice the agrochemical efficiency of the used soil conditioners and the optimal norms of manure are established.

Key words: agrochemical effectiveness; soil-conditioners; sweet pepper (Capsicum annum L.); wood ash; pot-tests
