[Organic Farming] Nutrients available for longer period Microbes decompose the complex organic compounds to mineral components and CO2. Further the mineral elements are converted in to available plant nutrients through mineralization process. These ions are held by organic matter and soil colloids and are slowly released as nutrients over a longer period. [Chemical Farming] 
Nutrients are available only for shorter period Certain fertilizers in the absence of microbes permanently fix on to the soil particles and may not be available for plant root absorption. In addition, the chemical fertilizers are easily water soluble and this may lead to various types of losses through leaching, evaporation, etc.
