serious soil degradation

, nitrogen leaching, soil compaction, reduction in soil organic matter, and loss of soil carbon. In addition, the efficacy of chemical fertilizers on crop yield has been decreasing over time [29, 31–32].

What are the harmful effects of using excessive fertilizers?

  • result in stunted growth and withering or death to the plants commonly known as leaf scorch;
  • decrease the organic matter in the soil leading to soil acidification;

How can we prevent negative effects of fertilizers?

The efficiency of fertilizer nitrogen can be increased and losses reduced, by matching supply with

crop demand

, optimizing split application schemes, changing the form to suit the conditions, and use of slow-release fertilizers and inhibitors.

What are advantages and disadvantages of fertilizers?

Manure adds nutrients to the soil without affecting its fertility. It does not damage the crops and produces healthy plants. Fertilizers are

chemicals which lower the fertility of the soil if used regularly

. They also damage the crops and make them unhealthy for consumption.

applying excessive amounts of fertilizer leads to the release of harmful greenhouse gases into the atmosphere

and the eutrophication of our waterways.

What are the effects of fertilizers and pesticides?

Following are the advantages of levelling: Levelling

helps to prevent soil erosion caused by wind or air

. It helps in sowing the seeds uniformly, and thus helps the plants to grow uniformly too. It helps in proper irrigation by allowing the water to get distributed uniformly throughout the soil.

What are the two harmful effects of chemical fertilizers?

Though chemical fertilizers increase crop production; their

overuse has hardened the soil, decreased fertility, strengthened pesticides, polluted air and water

, and released greenhouse gases, thereby bringing hazards to human health and environment as well.

Can fertilizer cause diseases?

poison people and pets

if they are inhaled or accidentally ingested. Touching the fertilizer may cause skin irritation, and ingesting it may be poisonous. Nitrates are the ingredients that cause the poisoning.

What is the effect of potassic fertilizers?

The results, though statistically insignificant at 5% level, showed

yield improvements with the application of

potassium fertilizers. Different levels of potassium treatment caused quality improvements such as higher specific weight, and more total soluble solids (TSS).
