Here is all information about Organic Farming and Chemical Farming.
Organic Farming vs Chemical Farming

Organic Farming Cultivation and production (Nutrient, pest & disease management) of crops by biodegradable organic inputs Chemical Farming Against Nature In chemically managed soil, the plant nutrients are supplied only through inorganic source, without any organic carbon source to derive food. This ultimately deprives the soil-eco system of the growth medium Organic Farming Harmony with nature In an organic management, the focus is on food web relations and element cycling aiming to maximize the agro- ecosystem's stability, sustainability and homeostasis (balanced equilibrium) Chemical Farming Blocks The Microbial Activity Due to the absence of carbon source, microbial population trends to be less or sometimes NIL in soil Organic Farming Increases The Microbial Life Organics is the main source for nutrients. The soil microbes derive the food from the carbaneous source and multiply and make the soil lively, also decomposing the complex organic compounds present in the added organics Chemical Farming Soil structure is destroyed Non-availability of binding material of the soil particles result in disintegration and reduce the soil granulation. In the long run it may reduce the productive capacity of land to harbor the crops & become unfit for production Soil structure improves. Organic Farming Soil becomes dead While chemical farming satisfies only the crop nutrient requirements, it is not conducive for biological environment of the soil, finally resulting in a problematic soil loaded with inorganic salts Soils become fertile Chemical Farming Continuous use of inorganic chemicals leads to changes in the pH of the soil (either acidic or saline depending on the type of fertilizer used). Organic Farming It unbalances the nutrient availability status and in some cases creates toxicity to the plants Buffering of soils (Enables neutral pH) Chemical Farming In addition, the chemical fertilizers are easily water soluble and this may lead to various types of losses through leaching, evaporation, etc. Nutrients available for longer period. Organic 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. Chemical Farming Leads to erosion Absence of binding agents (organic substances) between soil particles makes the soil particles to be easily detached by water and wind. It leads to loss of top fertile soils ultimately making the land barren and unfit for farming/cultivation Prevents the soil erosion Organic Farming Soil management techniques such as organic fertilization, mulching and cover cropping increases aggregation (by organic acid), improves soil structure and therefore increase the soil's water infiltration and retention capacity, substantially reducing the risk of erosion THANKS
