Advantage and disadvantage of chemical fertilizer in farming
Answers
•By using chemical fertilizers , we can replenish the soil more faster.
•There can be separate chemical fertilizers for replenishing particular type of nutrients.
•Chemical fertilizers are easily soluble in water and are easily absorbed by the plants.
•No need to wait for natural replenishment , thereby being more productive.
•By using chemical fertilizers we can ensure good yield.
DISADVANTAGES
•Continuous use of chemical fertilizers degrade the natural fertility of soil.
•These chemicals enter the food chain through the plants and as a result of bio magnification, these chemicals pose a threat to living creatures that consume them directly or indirectly.
•The soil is polluted and it's natural quality is degraded.
•These chemicals also enter the water table by seeping through the soil and thereby causing water pollution.

Answer:
Disadvantages of Chemical Fertilizers
Chemical fertilizers are substances that are either applied to soils or directly applied to plants; they provide optimal nutrients for their growth and development. These fertilizers are composed of raw chemicals that are manufactured at a factory either in liquid or solid form, these chemicals target plants specific nutritional needs. Chemical fertilizers are devised to mime natural plant nutrients. The nutrients that are contained in these fertilizers are nitrogen, phosphorus, and potassium and also other nutrients in smaller amounts. These nutrients are supplied to plants in form which can be easily absorbed and metabolized by plants.
Chemical fertilizers are inorganic material which are completely or partially synthetic and are added to the plant for their growth. Inorganic fertilizers are easily dissolved in the soil. These synthetic fertilizers are applied at a rate dependent in the fertility of the soil.
