Fertilisers Have distributed the ecology upto a large extent .State two alternatives that may be practised to overcome this problem.

• Only those fertilizers that do not burn leaves must be sprayed.
• Use the correct dosage/concentration of the fertilizer and at correct time intervals.
• Using organic fertilisers or mixture of manure and fertilisers helps to conserve the soil fertility. 
• Take precautions to protect non-pest species from direct exposure to fertilizers and from contamination due to drift, runoff or residues.
• Before applying any fertiliser, take into account the stage of plant development, the soil type and condition, the temperature, moisture and wind.
• The person applying the fertiliser should take care of personal safety.  Follow label directions carefully. When applying these chemicals, use gloves that are suited for the chemical. You should use a ventilation mask, too especially for powdered fertilizers. After application, the spreader or the implement needs to be washed really well.
• Avoid splashing, spilling, leaks, spray drift and contamination of clothing. Never eat, smoke, drink or chew while using fertilizers.
