Technological, agronomical and economic efficiency of new organic and organo-mineral soil amendments

The intensification of crop production coupled with current declining soil fertility needs proper plant nutrition management and improved effectiveness fertilizer use. Sustainable practices providing new amendments could be a useful tool to improve productivity causing economic benefits. technology processing local raw materials (leonardite, bentonite, molasses) was developed produce optimal physical chemical properties meet the particular in nutrients. best ratio components proved model experiment an estimation full cost final organic organo-mineral amendments. In field experiment, effect on available nutrients Chernozem Podzolic corn yield studied. Two doses methods application (banding broadcasting) were compared taking into account its efficiency. Development technologies fertilizing materials, compliance recommended doses, inputs increase efficiency emerging environmental
