ADVERTISEMENTS:
This article will help you to differentiate between organic and inorganic manure.
Difference # Organic Manure:
A. Organic manures are poor in plant food. They supply almost all the ingredients of plant food.
B. Physical Properties:
ADVERTISEMENTS:
(i) Soil structure – Organic manure improves the soil structure (granular).
(ii) Water-holding capacity – They improve water-holding capacity.
(iii) Permeability – By the use of organic manure, the soil become more permeable.
(iv) Drainage – It improves drainage in the soil.
ADVERTISEMENTS:
(v) Soil erosion – It checks the soil erosion.
(vi) Evaporation – It decreases evaporation loss from soil.
C. Chemical Properties:
(i) Nutrients slowly become available.
ADVERTISEMENTS:
(ii) It decreases leaching of nutrients from soil
(iii) It increases buffering capacity in the soil.
(iv) It supplies some micronutrients.
(v) Organic matter does not produce acidity or alkalinity in the soil.
ADVERTISEMENTS:
(vi) Organic manure upon decomposition produces organic acids which help to dissolve minerals such as potassium and make them more available to growing plants.
D. Biological Properties:
(i) It increases the growth of microorganism.
(ii) Microorganisms like earthworm gets their food from organic manure.
ADVERTISEMENTS:
E. Use:
(i) Organic manures are applied 15 to 30 days before the crop is sown.
(ii) It may not be used on standing crop.
(iii) Not used in liquid form.
(iv) Used in huge quantity.
(v) Organic manures are incorporated in soil.
Difference # Inorganic Manure:
A. They are rich in plant food and supply individually one or two elements of plant food only.
(i) No such effect on structure.
(ii) There is no effect on water-holding capacity.
(iii) No effect of fertilizer on permeability.
(iv) No effect.
(v) No effect on erosion.
(vi) No effect.
C. Chemical Properties:
(i) Quickly available, specially nitrogen-fertilizer.
(ii) No such effect.
(iii) Fertilizer has no such effect on soil.
(iv) Not supply micronutrients.
(v) Some fertilizers like sodium nitrage produces salinity and alkalinity in the soil.
(vi) No such effect.
D. Biological Properties:
(i) It slightly increases the growth of microorganism.
(ii) Microorganism do not utilize fertilizer for food.
E. Use:
(i) Nitrogen fertilizer is applied immediately before sowing. Phosphatic fertilizers are applied some days before sowing.
(ii) Used on standing crop.
(iii) Used in liquid form as foliar application.
(iv) Used in small quantity.
(v) It is also incorporated in the soil but may be used as top dressing.
