Question

The organic manure is better than fertilizers. Give reason.

Answer 1

Manures r partially decomposed organic material of biological origin added to the soil to Increase fertility of soil . they cause no harm to soil .


fertilizers r commercially produced synthetic chemical substances added to soil to overcome the deficiency of mineral nutrient to maintain fertility of soil. chemical fertizers enhance the crop yield on one hand and cause environmental hazard . and they destroy fertility of soil..


☆ Fertilizers give short term benefits where as manures give long term benefits therefore we must consider the use of manure for long term benefit.

Answer 2
