Which Crops Are Suitable for Ammonium Chloride? Usage Guide, Advantages and Restrictions

Ammonium chloride is a physiologically acidic quick-acting nitrogen fertilizer widely applied in agriculture. Featuring stable nitrogen content and high cost performance, it is extensively used for grain crops and fiber cash crops. Nevertheless, due to containing chloride ions and its property of acidifying soil, it has strict restrictions on applicable crops, soil types and application methods. Many growers encounter soil compaction, poor crop quality and low fertilizer efficiency because they fail to distinguish applicable scenarios and ignore fertilizer application taboos. This article comprehensively introduces the chemical characteristics, applicable crops, application features and prohibitions of ammonium chloride, guiding growers to apply fertilizer scientifically, avoid risks and increase yields.

Basic Physical and Chemical Properties of Ammonium Chloride

Ammonium chloride is synthetic ammonium nitrogen fertilizer with stable quality and pure nutrients, which serves as a cost-effective option for nitrogen supplementation in modern farming.

It appears as white crystals or crystalline powder, dissolves rapidly in water and forms weakly acidic aqueous solution. It has poor heat resistance. When the temperature rises above 100℃, ammonium chloride will decompose into ammonia and hydrogen chloride. Therefore, keep it away from high temperature and direct sunlight during storage and application.

Agricultural ammonium chloride contains 24%–26% nitrogen, classified as fast-acting nitrogen fertilizer that can be absorbed quickly by plants. As a physiologically acidic fertilizer, continuous long-term single application will lower soil pH value, cause soil acidification and compaction, which requires attention in daily planting management.

Suitable Crops and Application Scenarios of Ammonium Chloride

According to crops’ tolerance to chloride ions, ammonium chloride has clear matching crop varieties and shows stable fertilizer effects on suitable plants.

1.Grain Crops

It is especially ideal for paddy grain crops including rice, wheat, corn and sorghum. In paddy fields, chloride ions can inhibit soil nitrification, reduce nitrogen loss via leaching, maintain lasting fertilizer efficiency. It is regarded as one of the preferred nitrogen fertilizers for rice cultivation.

2.Fiber Cash Crops

It works well for cotton, hemp and other fiber crops. Moderate chloride ions facilitate fiber synthesis, strengthen plant toughness and improve lodging resistance, which helps enhance yield and quality of cash crops.

3.Common Vegetables

Most ordinary vegetables can receive ammonium chloride appropriately to satisfy nutrient demands in seedling and growing periods and support robust plant growth.

Application Characteristics and Advantages of Ammonium Chloride

Compared with conventional nitrogen fertilizers such as ammonium sulfate, ammonium chloride has prominent advantages in cost and practical application, especially for large-scale farm planting.

First of all, ammonium chloride boasts higher nitrogen content and lower unit fertilizer cost, cutting planting investment, suitable for base fertilizer and topdressing on large farmland.

In addition, it performs excellently in paddy field application. It will not produce toxic hydrogen sulfide, preventing root rot caused by toxic substances. Meanwhile, it extends fertilizer duration and improves nutrient utilization rate, making it a high-efficiency and economical nitrogen fertilizer for rice fields.

As a quick-acting nitrogen fertilizer, it can effectively relieve chlorosis, weak growth and developmental stagnation caused by nitrogen deficiency. It is available for emergency nutrient supplement during crop growth cycles.

Strict Prohibitions and Restrictions for Using Ammonium Chloride

Ammonium chloride cannot be used universally. Certain crops and soil conditions are not applicable. Improper application will severely damage crop yield and soil health.

Crops Sensitive to Chloride Are Forbidden:

Never apply ammonium chloride on chloride-sensitive crops. Accumulated chloride ions will cause fertilizer damage. Restricted crops include tobacco, potato, grape, citrus, tea tree and sugar beet. Application will lead to worse product taste, decreased output and weaker disease resistance.

Unsuitable Soil Conditions:

Long-term or heavy application is banned on saline-alkali soil and acidic soil. Application on acidic soil will aggravate acidification and compaction; usage on saline-alkali land will accelerate salt accumulation and destroy soil structure.

Application Limitations:

Ammonium chloride cannot be used as seed fertilizer or seedling bed fertilizer, as it may burn seeds and young roots, resulting in uneven germination and seedling death.

It is not recommended for arid regions with low rainfall. Insufficient soil water cannot dilute chloride ions, easily triggering salt accumulation and root injury.

For lands using ammonium chloride for years, organic fertilizer or alkaline materials such as lime must be applied together to neutralize soil acidity, improve soil texture and avoid compaction.
