<em>Repeated use of chemical fertilizers has several adverse impacts.
</em>
<u>Explanation:</u>
<em>Chemical fertilizers are used to increase crop yield and raise agricultural productivity.</em> But a land loses its fertility over the years due to repeated fertilizer use.
<em>Excess use of fertiliser makes the soil acidicby reducing the organic content of the soil. </em>
When the amount of chemical fertilizers containing nitrogen is applied is beyond the amount that can be absorbed by the plants, it results in the release of greenhouse gases into the atmosphere.
<em>When the fertilizers are washed into water bodies their nutrient content increases heavily and this depletes the oxygen in water.
</em>
