FIELD: production of fertilizers. SUBSTANCE: source substrate is treated with an ammonia reagent and subjected to energy action at conditions ensuring complexing of active substrate groups, which is monitored by IR-spectrometry method. The resultant product may be used for cultivation and/or recultivation of lands not suitable for agriculture. The product may be also used as an organic fertilizer of prolonged activity for all soil and climatic regions and for all agricultural crops. EFFECT: improved production method. 2 cl, 2 dwg
