What are the bad effects of chemical fertilizers?

Answer 1

They harm the soil by making it acidic. The acidic material does not allow the plants to grow. the soil then has to be neutralised by adding basic material to it.

They can actually poison your plants not only the annoying bugs that eat them. Also if you have a pet and it gets into the plant that has been sprayed, it can be fatal. It also kills many good living creatures that we need.

A lot of the fertilizer is washed off and makes its way to contaminate waterways where it is not welcome.

Answer 2

Using too much fertiliser on a farm, could mean that the nitrogen in the fertiliser will run off into near by ponds and lakes. Then you will get a layer of algae forming on the waters surface. This layer is air and light tight, so all the aquatic and marine life in the water will use up all the oxygen, and die

Answer 3

In itself, spraying fertilizers is not bad. However, some fertilizers may have harmful additives or pesticides mixed in. Also, fertilizer run-off could upset the ecological balance, get into drinking water, and cause excessive algae growth in bodies of water.

Answer 4

When rain comes down, it spreads the fertilizer into the rivers, and makes the water animals die .

Answer 5

Some toxic fertilizers might poison food, or go into lakes and rivers and cause red algae which blocks sunlight from other plants.

Answer 6

There are bad side effects that come along with the overuse of artificial fertilizers. This can cause damage to crops and cause health problems in humans.
