Types of Fertilizer for Plants and Differences

Many artificial fertilizers contain acids, such as sulphuric and hydrochloric acid, which tend to increase the acidity of the soil, reduce the soil's beneficial organism population and interfere with plant growth. Continued use of chemical fertilizer may destroy nitrogen-fixing bacteria. Furthermore, chemical fertilizers may affect plant health.

organic fertilizer such as manure adds nutrients to soil, increases soil organic matter, improves soil structure, improves water holding capacity, reduces soil crusting problems, reduces erosion from wind and water.

Improves water holding capacity and improves buffering capacity ag ainst fluctuations in pH levels.
Therefore the use of organic fertilizer will be the best choice for any gardening project, as well as more environment friendly.

Where the use of chemical fertilizer, will be more detrimental to your soil and not at all environment friendly.

Organic matter improves all soils. If the soil has too much clay the organic matter increases the drainage of the soil, so that it drains better, allowing more oxygen, and preventing water logging. The water is absorbed into the soil, and does not run off, preventing soil erosion. If the soil is too sandy.
The organic matter retains water in the soil, and stops the soil drying out, keeping the roots moist, and cutting down on watering. So organic matter makes all soils better!
