Ammonium bicarbonate should not be applied deeper than 6 cm, and the soil must be covered immediately after application to prevent nutrient loss. Additionally, it is not recommended for use in greenhouses because ammonium bicarbonate is often referred to as "gas fertilizer." In enclosed environments, it tends to decompose quickly into ammonia gas, leading to significant volatilization and reduced effectiveness.
Ammonium sulfate is a physiologically acidic fertilizer, and long-term use on the same plot of land can increase soil acidity, which may harm soil structure and reduce its fertility over time. In alkaline soils, ammonium ions are absorbed by plants, while the sulfate ions remain in the soil. These acid-forming ions can react with calcium, causing soil compaction and making the soil harder and less workable.
When chlorinated fertilizers such as ammonium chloride or potassium chloride are applied to saline-alkali soils, the chloride ions tend to accumulate in the soil over time. This accumulation can lead to increased soil salinity and worsen salt damage, ultimately affecting plant growth and yield. Therefore, it's important to manage the use of these fertilizers carefully, especially in sensitive soil conditions.
It’s always advisable to conduct regular soil tests and follow proper fertilization guidelines to maintain soil health and ensure sustainable agricultural practices. Understanding the characteristics of different fertilizers helps farmers make informed decisions that benefit both the environment and crop productivity.
