Which of the following is nitrogenous fertilizers

Options

A. Bone meal
B. Thomas meal
C. Nitro phosphate
D. Ammonium sulphate

Explanation

To determine which of the given options is a nitrogenous fertilizer, we can follow these steps:

### Step 1: Understand Nitrogenous Fertilizers
Nitrogenous fertilizers are those that contain nitrogen in a form that can be utilized by plants. The most common nitrogenous fertilizers include urea, ammonium sulfate, ammonium nitrate, and calcium nitrate.

### Step 2: Identify Common Nitrogenous Fertilizers
- **Urea (CO(NH2)2)**: A widely used nitrogenous fertilizer.
- **Ammonium Nitrate (NH4NO3)**: Contains both ammonium and nitrate forms of nitrogen.
- **Ammonium Sulfate ((NH4)2SO4)**: Contains ammonium ions and is also a source of sulfur.
- **Calcium Nitrate (Ca(NO3)2)**: Contains both calcium and nitrate forms of nitrogen.

### Step 3: Analyze the Given Options
From the video transcript, we can identify the following:
- **Ammonia (NH3)**: While it is a raw material for fertilizers, it is not directly used as a fertilizer itself.
- **Urea**: Clearly mentioned as a nitrogenous fertilizer.
- **Sodium Nitrate (NaNO3)**: Contains nitrate but is not a nitrogenous fertilizer in the traditional sense as it does not provide nitrogen in a form that is primarily utilized by plants.
- **Ammonium Nitrate**: This is a nitrogenous fertilizer.
- **Ammonium Sulfate**: This is also a nitrogenous fertilizer.
- **Nitro Phosphate**: Typically contains phosphorus and is not classified as a nitrogenous fertilizer.

### Step 4: Conclusion
Based on the information analyzed, the nitrogenous fertilizers from the options provided include:
- **Urea**
- **Ammonium Nitrate**
- **Ammonium Sulfate**

### Final Answer
The nitrogenous fertilizers mentioned in the options are **Urea, Ammonium Nitrate, and Ammonium Sulfate**.
