1、Impact of the addition of a compound fertilizer on the dissolution of carbonate rock tablets: A column experiment

In this study, two columns (a control column and a fertilizer column) with carbonate rock tablets in the bottom of each were established to explore the impact of the addition of a compound fertilizer on the dissolution of carbonate rock tablets.

2、Elemental source attribution signatures for calcium ammonium nitrate (CAN) fertilizers used in homemade explosives

Calcium ammonium nitrate (CAN) is a widely available fertilizer composed of ammonium nitrate (AN) mixed with some form of calcium carbonate such as limestone or dolomite. CAN is also frequently used to make homemade explosives.

3、Nitrogen loss from ammonium bicarbonate and urea fertilizers applied to flooded rice

Denitrification losses, calculated as the difference between total nitrogen loss and ammonia loss, were 42.2% and 39.3%, respectively, for ammonium bicarbonate and urea, and thus were more important than ammonia losses from both types of fertilizer.

4、Mixing Manure with Chemical Fertilizers, Why?and What is After?

Using chemical fertilizers or organic manure alone as amendments may bring negative effects to the quality of crops. Neither of these alone can sustain productivity. Hence, judicious uses of organic manure with chemical fertilizers are essential to augment productivity of crops.

Ammonium bicarbonate used as a nitrogen fertilizer in China

This article reports a modified process for the production of synthetic ammonia, in which CO 2 in the converted water gas is removed by the synthesized ammonia itself, and the precipitated NH 4 HCO 3 serves as the final product of the factory.

Synthesis and characterization of nano

The synthesized nano-micronutrient fertilizers were analyzed by X-ray diffraction (XRD) and transmission electron microscopy (TEM). The results showed that 40 mg/L of NFs was the most effective ...

Impact of fertilization with irrigation on carbonate weathering in an agricultural soil in Northern China: A column experiment

In this study, four soil columns with different treatments (control (CK), fresh cow manure (FM) urea (NF) and diammonium phosphate (PF)), were established to explore the influence of fertilization and irrigation on carbonate weathering in an agricultural area in Northern China.

Interactions between nitrate and ammonium in their uptake, allocation, assimilation, and signaling in plants

Mixtures of nitrate and ammonium are beneficial in terms of plant growth, as compared to nitrate or ammonium alone, and therefore synergistic responses to both N sources are predicted at different steps ranging from acquisition to assimilation.

From ammonium bicarbonate fertilizer production process to power plant CO2 capture

Industrial ammonium bicarbonate fertilizer production processes are proven technology and have been optimized both technologically and economically for decades. This technology is also based on the chemistry and physics of the NH 3 –CO 2 –H 2 O system.

Ammonium carbonate, commonly known as carbon amine, is a widely used fertilizer primarily designed to supply essential macronutrients such as nitrogen (N), phosphorus (P), and potassium (K). the application of macro-element fertilizers (e.g., nitrogen, phosphorus, and potassium fertilizers) remains critically important in agricultural production. So, can ammonium carbonate be mixed with macro-element fertilizers? Why or why not? Below is a detailed analysis:

1. Functional Differences: Ammonium carbonate mainly provides N, P, and K, while macro-element fertilizers focus on delivering N, P, K, calcium (Ca), magnesium (Mg), sulfur (S), and other key nutrients. The distinct functions of these fertilizers could lead to competition for nutrients, adversely affecting crop growth.

2. Nitrogen Imbalance: Ammonium carbonate has a high nitrogen content but lower levels of phosphorus and potassium. In contrast, macro-element fertilizers contain balanced proportions of N, P, and K. Mixing them may cause excessive nitrogen supply, inhibiting the absorption of other nutrients and disrupting normal crop development.

3. Phosphorus Overload: Since ammonium carbonate contains little phosphorus, while macro-element fertilizers are rich in phosphorus, combining them could result in phosphorus oversupply, which might restrict the uptake of other nutrients and harm crops.

4. Potassium Imbalance: Ammonium carbonate has low potassium content, whereas macro-element fertilizers are potassium-rich. Mixing them could lead to excess potassium, interfering with the balance of other nutrients and impairing crop health.

5. Microelement Disruption: Ammonium carbonate lacks microelements like Ca, Mg, and S, which are abundant in macro-element fertilizers. Combining them might overwhelm crops with microelements, disrupting their absorption and utilization.

6. Nutrient Ratio Imbalance: The proportional composition of N, P, and K in ammonium carbonate often differs from that in macro-element fertilizers. Mixing them could create imbalanced nutrient ratios, negatively impacting crop growth.

7. Soil Environmental Risks: The primary nutrients in ammonium carbonate may negatively affect soil conditions. Combined use with macro-element fertilizers could exacerbate soil deterioration, harming crop productivity.

8. Soil Microbial Activity: The nutrients in ammonium carbonate might reduce soil microbial activity. Mixing with macro-element fertilizers could further suppress microbial function, diminishing soil fertility and crop performance.

9. Soil pH Fluctuations: Ammonium carbonate may alter soil pH. When mixed with macro-element fertilizers, this could cause unstable pH levels, stressing crops and hindering growth.

10. Chemical Interactions: The nutrients in ammonium carbonate might interact with other fertilizers, pesticides, or chemicals, leading to unpredictable effects on crop health.

Mixing ammonium carbonate with macro-element fertilizers risks nutrient competition, imbalanced ratios, soil degradation, and other issues detrimental to crops. in agricultural practice, it is advisable to avoid combining these two types of fertilizers.
