Organic Fertilizer Vs Chemical Fertilizers in Soil


Criteria for Comparision Chemical Fertilizers Organic Fertilizer
Macro nutrient Contents Mostly contain only one (N in urea) or at the most two (N & P in DAP) nutrients in any one type of cheical fertilizer. Contain all i.e. Nitrogen (N), Phosphorus(P) & Potassium (K) in sufficient quanities.
Secondary nutrient contents Not Available Calcium (Ca), Magnesium(Mg) and Sulphur (S) is available in required quantities
Micro nutrient Contents Not Available Zinc (Zn), Boron(B), Manganese(Mn), Iron(Fe), Copper(Cu), Molybdenum(Mo) and Chlorine(Cl) also present.
pH balancing Disturb Soil pH to create salinity and alkalinity Helps in the control of soil pH and checks the salinity and alkalinity in soil
EC correction Creates imbalance in soil EC affecting nutrients - assimilation Helps in blancing theED to improve plant nutrient absorption
Organic Carbon Not Available Very high organic carbon and humus contents improves soil characteristics
Moisture retention capacity Reduce Moisture retention capacity of the soil Increase moisture retention capacity of the soil
Soil Texture Damages soil texture to reduce aeration Improves moisture retention capacity of the soil
Beneficial Bacteria and Fungi Reduces biological activities and thus the fertility is impaired Very high biological life improves the soil fertility and productivity on substainable basis.
Plant growth harmones Not Available Sufficient quantity helps in better growth and production
