💥 Macam Jenis Pupuk Yang Tidak Boleh Di Tabur‼️Beda Pupuk Nitrat dan Pupuk Amonium‼️Bisa Bahaya 💥

Summary

In this informative video, the speaker discusses the proper application of nitrogen-based fertilizers, specifically ammonium fertilizers, and the risks associated with improper methods. He highlights that while broadcasting fertilizers (tabur) is commonly recommended, it can lead to significant losses if the fertilizers are not covered after application. Ammonium-based fertilizers, such as urea and ammonium nitrate, can easily evaporate, wasting valuable resources. The speaker advises farmers to bury fertilizers after spreading them to prevent evaporation and ensure their effectiveness, emphasizing the importance of understanding fertilizer types and application methods to avoid financial losses.

Takeaways

• 😀 The video warns against using certain fertilizers in a 'scatter' application method, suggesting it could lead to financial losses.
• 😀 The script highlights that fertilizers come with different application methods: scattering, watering, and spraying, each with unique benefits and risks.
• 😀 Scattering fertilizers directly onto the soil without covering them can cause significant nutrient loss, particularly with ammonium-based fertilizers.
• 😀 Ammonium in fertilizers is volatile and can evaporate when exposed to heat or sunlight, causing nutrients to be lost to the air.
• 😀 Fertilizers containing ammonium (such as urea and ammonium nitrate) should be buried or covered after scattering to prevent evaporation of nutrients.
• 😀 Nitrogen in fertilizers exists in various forms, such as ammonium and nitrate, each with different properties regarding volatility and plant absorption.
• 😀 The video emphasizes the need to check the type of nitrogen in fertilizers to ensure correct application methods and avoid wasting resources.
• 😀 It explains the difference between ammonium-based fertilizers, which are prone to evaporation, and nitrate-based fertilizers, which are more stable in soil.
• 😀 Fertilizers with ammonium should not be left uncovered, as this can lead to significant nutrient loss, especially for plants in the vegetative phase.
• 😀 The script stresses that proper application of fertilizers is crucial, especially given the high costs and potential scarcity of fertilizers in the current market.
• 😀 Finally, the video hints at upcoming content explaining why ammonium fertilizers behave differently in flooded rice paddies compared to other crops, offering more insight into agricultural practices.

Q & A

Why does the speaker warn against scattering fertilizers like ammonium-based ones without covering them?

The speaker warns that ammonium-based fertilizers, such as urea and ammonium nitrate, are prone to evaporation, especially when exposed to sunlight or heat. If these fertilizers are scattered on the surface without being covered, the nitrogen they contain will evaporate, leading to significant nutrient loss and wasted resources.

What is the primary danger of applying ammonium fertilizers improperly?

The primary danger is that ammonium in fertilizers is a gas that can evaporate easily. When not covered or buried, it escapes into the air, reducing the amount of nitrogen available to plants, which affects their vegetative growth and can lead to financial loss due to inefficient fertilizer use.

How does the speaker suggest correctly applying ammonium-based fertilizers?

The speaker recommends that after scattering the ammonium-based fertilizer (tabur), it should be covered or buried to reduce the risk of evaporation. This helps retain the nitrogen in the soil, making it available to the plants for proper growth.

What is the difference between ammonium and nitrate nitrogen in fertilizers?

Ammonium nitrogen is a gas that is more volatile and prone to evaporation, whereas nitrate nitrogen is more stable and difficult to evaporate. Nitrate is the final form of nitrogen after ammonium has been broken down, and it does not easily revert back to gas.

Why is ammonium nitrogen especially important for plants during the vegetative phase?

Ammonium nitrogen is crucial for the formation of amino acids, which are essential for plant growth, especially during the vegetative phase. It helps in building the plant's structure and promoting early growth. Without it, plants may struggle to develop properly.

Can fertilizers containing ammonium nitrogen be left uncovered in all agricultural settings?

No, fertilizers containing ammonium nitrogen should not be left uncovered in most agricultural settings because they will evaporate and be wasted. However, in flooded rice fields, the water helps to retain the nitrogen, preventing it from evaporating, making the practice of scattering and leaving it less problematic.

What are the three main methods of applying fertilizers, according to the speaker?

The three main methods of applying fertilizers are: 1) 'tabur' (scattering), 2) 'kocor' (watering), and 3) 'sprayer' (spraying). Each method has its own advantages, but the speaker specifically emphasizes the correct approach for scattering, which involves covering the fertilizer afterward.

Why is it important to properly manage fertilizer application, especially in times of rising fertilizer prices?

With rising fertilizer prices and potential shortages, improper application can lead to wasted resources, resulting in financial losses. Properly managing fertilizer use ensures that the nutrients are efficiently absorbed by the plants, helping farmers maximize their investment and improve crop yields.

What types of fertilizers commonly contain ammonium nitrogen?

Common fertilizers containing ammonium nitrogen include urea, ammonium nitrate (found in some NPK fertilizers), ammonium sulfate, ammonium phosphate (SS Amofos), and others. These fertilizers should be applied carefully to avoid nitrogen loss through evaporation.

How does the application of fertilizers differ between dry land farming and flooded rice fields?

In flooded rice fields, fertilizers containing ammonium nitrogen are less likely to evaporate because the water helps retain the nitrogen. In contrast, on dry land, ammonium nitrogen is more prone to evaporation if left uncovered, which is why it needs to be buried or covered after scattering.
