Answer 1

Answer:

a) Organic farming is an agricultural system which originated early in the 20th century in reaction to rapidly changing farming practices. Certified organic agriculture accounts for 70 million hectares globally, with over half of that total in Australia.

b) Biofertilizers consist of plant remains, organic matter and some special class of micro-organisms. Biofertilizers help to increase quality of the soil by providing nutrients and natural environment in the rhizosphere.

c) Chemical fertilizers are predictable and reliable. The Fertilizer can be used in poor soil to make it fertile immediately. They add a sufficient amount of nutrients needed by the plant. They contain the three essential nutrients (NPK) needed for plant growth.
