1、Which Fertilizer Should Not Be Mixed Together When Applied?

Nitrate fertilizers, such as calcium nitrate, can react with sulfur-based fertilizers, such as elemental sulfur, to form nitrogen oxides. These gases can contribute to air pollution and may be harmful to plants.

2、Nitrogen Fertilizer

Nonetheless, as the application of nitrogen fertilizers increased, more and more varieties adapted to high fertilizer were selected by breeders, resulting in modern varieties showing nitrogen tolerance as well as a reduced effect of nitrogen on yield improvement.

3、Hazards of nitrogen fertilizers and ways to reduce nitrate accumulation

In modern agriculture, farm produce accumulates a lot of nitrates that can reach toxic levels owing to the unfair use of nitrogen fertilizers, cultural methods, farming policies in multiple areas of the world, thereby increasing concerns about the availability of hygienic food supply and environmental hazards.

4、Nitrogen Fertilizers: Types, Benefits, And Application Tips

Without this natural gas, we cannot make nitrogen-based fertilizers; our only option is to use its limited resources for farming. Nitrogen fertilizers typically come in one of these forms: nitrate (NO3), ammonia (NH3), ammonium (NH4), or urea (CH4N2O).

5、Fertilizer Compatibility & Mixing Law: Which Fertilizers Can Be Mixed?

Let’s evaluate the compatibility of the most crucial agricultural fertilizers with each other. Nitrogen fertilizers, known for their high mixing ability, exhibit excellent compatibility.

Nitrogen Fertilizer Types, Uses, and Benefits Explained

When to apply: Nitrogen fertilizers should typically be applied during the growing process, rather than pre-applied, based on the plants' health. Also, never apply nitrogen fertilizers during heavy rain or when heavy rain is expected; it'll wash away before reaching the roots.

Why nitrate nitrogen fertilizer should not be applied in paddy

Since nitrate is a negatively charged anion and cannot be adsorbed by negatively charged soil colloidal particles, nitrate nitrogen fertilizer can only exist in the soil solution after being applied to the soil and move with the movement of soil water.

What fertilizers should not be mixed?

(5) Fertilizer should not be mixed with bacterial fertilizer such as rhizobia fertilizer.Because the chemical fertilizer has strong corrosive, volatile and water absorption, if applied together with bacterial fertilizer, it will kill or inhibit the living bacteria, making the fertilizer ineffective.

Fertilizer Quick Guide

Slow-release fertilizers need not be applied as frequently as other fertilizers, and higher amounts can be applied without danger of burning plants. Plants generally use the nitrogen in slow-release fertilizers more efficiently than nitrogen in other forms, since it is released over a longer period of time and in smaller quantities.

When and How to Apply Nitrogen Fertilizer

In this article, we will explore when and how to apply nitrogen fertilizer for various crops, considering soil conditions, climate, crop type, and best management practices. Nitrogen (N) is a primary macronutrient that plants need in large quantities.

Nitrogen fertilizers are essential nutrients for plant growth, but not all nitrogen fertilizers are suitable for all types of plants. Below are some situations where specific nitrogen fertilizers should be avoided:

1. High-Nitrogen, Low-Phosphorus, and Low-Potassium Fertilizers: While these fertilizers provide abundant nitrogen, they lack other critical nutrients like phosphorus and potassium. This can lead to slow plant growth and reduced disease resistance. avoid using such fertilizers for crops requiring high phosphorus and potassium, such as peanuts and potatoes.

2. Excessive Nitrogen Application: Overuse of nitrogen fertilizers can disrupt a plant’s normal development due to excessive nitrogen accumulation. Additionally, it may cause soil acidification and groundwater pollution. Follow the principle of "applying in small amounts and multiple times" to avoid heavy, one-time applications.

3. Avoid Ammonium Nitrogen Fertilizers in Acidic Soils: Ammonium-based fertilizers decompose rapidly in acidic soils, releasing ammonia gas and worsening soil acidity. In such cases, opt for alternative nitrogen sources like urea.

4. Avoid Nitrate Nitrogen Fertilizers in Alkaline Soils: Nitrate-based fertilizers may react with iron ions in alkaline soils, forming nitrites and reducing fertilizer effectiveness. Instead, use alternatives like ammonium sulfate.

5. Do Not Directly Apply Uncomposted Organic Fertilizers: Uncomposted organic matter and microorganisms in raw organic fertilizers can disrupt soil structure and harm plant growth. Compost or ferment organic materials thoroughly before application.

6. Avoid Heavy Metal-Containing Fertilizers: Some chemical fertilizers contain heavy metals, which can accumulate in soils over time. Choose eco-friendly, national standard-compliant products to minimize environmental risks.

7. Limit Chloride-Containing Fertilizers: Chloride ions in these fertilizers can bind with soil calcium, reducing water retention and damaging plant roots. Use chloride-containing fertilizers sparingly.

8. Avoid Fluoride-Containing Fertilizers: Excessive fluoride from certain fertilizers can interfere with plants’ ability to absorb fluorine and hinder growth. Exercise caution when applying fluoride-containing products.

9. Do Not Use Arsenic-Containing Fertilizers: Arsenic is toxic to plants. Avoid excessive application of arsenic-containing fertilizers to prevent growth damage.

select nitrogen fertilizers based on plant requirements and soil conditions. Avoid blind or excessive application to prevent harm to plants and soil. Prioritize environmentally friendly, national standard-compliant products to promote sustainable agriculture while protecting ecosystems.
