Which type of chemical fertilizer is mostly used in Pakistan?
In Pakistan, farmers predominantly use Urea (46:0:0) and DAP (18:46:0). There is a general under application of Potash (K) fertilizers leading to crop yields far lower than the potential. The Nitrogen (N) in Urea and DAP is provided by ammonia, a raw material derived from natural gas.
What are the main types of chemical fertilizers?
Various examples of chemical fertilizers are sulphate, ammonium phosphate, potassium sulphate, etc. Nitrogenous fertilizers are a type of chemical fertilizer which provides the salt of nitrogen for the proper growth and development of plants. Phosphorous fertilizers contain phosphorus as the main constituent.
What are the three main types of chemical fertilizers?
Chemical Fertilizers Types: 3 Types of Chemical Fertilizers
- Nitrogenous Fertilizers:
- Phosphate Fertilizers:
- Potassic Fertilizers:
What are the four chemical fertilizers?
There are various nitrogenous chemical fertilizers like ammonium sulphate, calcium ammonium nitrate, basic calcium nitrate, calcium cyanamide (nitrolium), urea etc. Obviously these fertilizers supply nitrogen to the soil.
Which is better urea or DAP?
Urea phosphate showed its superiority over DAP for grain yield as well as P-fertilizer efficiency (PFE). Urea phosphate at 60ppm P2O5 produced higher grain yield (9.24g per pot) as compared to DAP (80ppm P2O5, 8.98g per pot).

What are chemical fertilizers?
The exact ingredients and the proportions of each of them vary between different types of fertilizer. The three main components all fertilizer mixture have, though, are nitrogen, phosphorus, and potassium.
Why are chemical fertilizers used?
Chemical fertilizers allow growers to maximize their crop yield on a specific piece of land — the more the plant grows, the better. Fertilizer works to ensure that each piece of land produces as efficiently as possible.
What are the most widely used chemical fertilizers?
1. Nitrogen Fertilisers: The primary deficiency of nitrogen in all temperate and tropical countries demands top priority for the manufacture of nitrogen fertilisers. Nitrogen fertilisers are the most widely produced and most commonly used.
What are the advantages of chemical fertilizers?
Advantages:
- Chemical fertilizers are predictable and reliable.
- The Fertilizer can be used in poor soil to make it fertile immediately.
- They add a sufficient amount of nutrients needed by the plant.
- They contain the three essential nutrients (NPK) needed for plant growth.
What are two chemical fertilizers?
Science > Biology > Management of Crop Production > Chemical Fertilizers
- Nitrate Fertilizers: e.g. Sodium nitrate.
- Ammonium Fertilizers: e.g. Ammonium sulphate.
- Nitrate and ammonium fertilizers: e.g. Ammonium sulphate.
- Amide fertilizers: e.g. Urea.
Is NPK a chemical fertilizer?
Chemical fertilizers and organic fertilizers show their nutrient content with three bold numbers on the package. These numbers represent three different compounds: Nitrogen, Phosphorous, and Potash (Potassium), which we can also describe with the letters N-P-K.
