Question

how are biofertilizers more beneficial as compared to chemical fertilizers

Answer 1

In general, chemical fertilizers provide three major plant nutrients; nitrogen, phosphorus and potassium or NPK. However, the ever increasing cost of commercial fertilizer products driven, in part, by the inevitable depletion of global phosphorus, is forcing producers to look for alternative sources like bio-fertilizers and other organically-based solutions.

The primary advantages of using biosolids as a fertilizer alternative are cost efficiencies and the presence of nutrients and organic matter. Returning these valuable materials back to the soils is a critical element in long-term sustainability.  Typically, Class B biosolids contain the nitrogen, phosphorus and organic matter required to promote plant growth and healthy soil conditions, but they are low in potassium. In other words, they have the N & P, but lack the K required to be achieve optimal performance. The Class A (EQ) LysteGro™ biofertilizer product has predictable NP & K values and it is rich in organic matter, making it ideal for agriculture and many other beneficial uses.

Answer 2

$<b>Answer :</b>$

Biofertilizer- Biofertilizer is also known as manure. Organic manure is plant and animal wastes that are used by farmers as a source of nutrients for the plants.

Chemical fertilizers- Inorganic chemicals/materials of synthetic origin that is applied to soil as a source of nutrients for the plants.

Biofertilizers are more beneficial as compared to chemical fertilizers because :-

1. eco-friendly so it does not cause any harms to soil and nature.

2. It also helps in increasing the soil fertility. It adds humus to the soil.

3. manure is cheap compared to the fertilizers.

4. It Slows down global warming.

5. Species richness - organic farms are rich in species like an earthworm, birds, butterfly, beetles, spiders, soil microbes etc.

6. Enhance water holding capacity of the soil.

Whereas

Chemical fertilizers help in increasing the crop productivity but make the soil infertile. They change the Ph of the soil. They kill the various microbes, plant species which effect the entire ecosystem.

Long-term use of chemicals can also cause greenhouse effect. It contaminates the groundwater as chemical fertilizers are water soluble.
