Chemical fertilizer disadvantage

1. Repeatedly application of chemical fertilizers reduces soil friability.
2. Crop grow better but so weed for this reason need to apply herbicide spray in plant.
3. Repeatedly use of chemical fertilizers increases salt amount in soil. Due to excessive salt in the soil force to plant expand more engergy to draw water from soil. For this reason soil dried out.
4. Inorganic fertilizers release large amount of nitrogen (N) . This excessive nitrogen(N) mixed with phosphate(P) create a plant disease mosaic infection.
5. Nitrogen fertilizers find in way into rivers, lake and the ocean where it cause eutrophication that hamper aquatic life.
6. Improper way use of chemical fertilizers and herbicide can damage farmer health.

Land degradation occurs when the economic and biological productivity of land is lost, primarily through human activities. Land Degradation Major Causes: 1. Deforestation : Deforestation cause due to increasing demands of fuel and forest products which results into degradation of land resources. 2. Agricultural Practices : The modern agricultural system uses excessive fertilizers and pesticides has adversely degraded the natural quality and fertility of the cultivation land. 3. Industrialization: Rapid growth industries of the country leads to excessive deforestation and utilization of land in such as way that it has lost its natural up gradation quality. 4. Urbanization: One of the main reason land degradation is increasing growth of population demand for more residential areas...
