Answer:The by-products of the fertiliser industries are oxides of nitrogen and sulphur i.e., SO2, CO, NOX, CO2, H2S, other solid, liquid chemicals and some solid waste material. These substances usually released in air or dump in river bodies or sea which causes water pollution.

When natural fertilizers are used, the nutrients remain in the soil for a longer period than when Turf Builder is used. Fertilizers are divided into categories of synthetic and natural. When comparing natural and synthetic fertilizers, the former one improves the quality of the soil.

While the use of nitrogen as a fertilizer has brought enormous benefits, the loss of fertilizer nitrogen to the environment also has many side effects, including reduced biodiversity and the formation of marine algal blooms.

When ammonia is used as the nitrogen source in a fertilizer, one method of synthetic production requires the use of natural gas and air. The phosphorus component is made using sulfur, coal, and phosphate rock. The potassium source comes from potassium chloride, a primary component of potash.

NPK fertilizers are fertilizers that contain the elements nitrogen (N), phosphorus (P), and potassium (K). ... Nitrogen is good at making the leaves grow. Phosphorus improves fruit and/or flower production as well as root growth. Potassium is great for overall plant health.

How is ammonia used? About 80% of the ammonia produced by industry is used in agriculture as fertilizer. Ammonia is also used as a refrigerant gas, for purification of water supplies, and in the manufacture of plastics, explosives, textiles, pesticides, dyes and other chemicals.

Farmyard manure is a fertilizer composed of waste products, typically dung and urine, produced by farm animals, most commonly cows. The waste products contain a wealth of nutrients, including the extremely important element that plants need—nitrogen. There isn't an involved process to prepare farmyard manure.

In biodiesel, the most significant residues and by-products are glycerol, biodiesel washing wastewaters, methanol, and solid residues (Varanda et al. 2011). Glycerol is the by-product that generates the largest interest, because it can involve the largest revenue for the biodiesel industry.

Typically, fertilizers are composed of nitrogen, phosphorus, and potassium compounds. They also contain trace elements that improve the growth of plants. The primary components in fertilizers are nutrients which are vital for plant growth. Plants use nitrogen in the synthesis of proteins, nucleic acids, and hormones.

Manure provides soil structure and nutrients whereas fertilizers only provide nutrients and even that is mainly nitrogen, potassium and phosphorous. Manure can also be used in excess and wont ruin or destroy anything whereas fertilizers used in excess will cause water pollution or ruin the soil fertility.

The biggest disadvantage of using an organic fertilizer is that it may not contain primary nutrients like nitrogen, phosphorous or potassium, also known as NPK. Manure-based fertilizers contain these nutrients and are still considered organic. However, many others don't contain significant quantities of NPK.

Fish makes a very good natural fertilizer for nitrogen and trace minerals. In fact, it works so well that many Native American horticulturalists buried a fish at the base of each crop plant.
