Lime nitrogen is a toxic substance that expands when exposed to moisture and releases harmful gases. In high-temperature environments, it can cause fires or explosions, so strict safety measures must be followed during storage and handling.
It is important not to store food, seeds, feed, or tobacco in the same warehouse as chemical fertilizers, as this can lead to contamination, spoilage, or even poisoning. The storage area should remain dry, well-ventilated, and protected from direct sunlight. Fertilizers should not be placed directly against walls or the ground, and they should be stacked at a height of 2 to 3 feet to prevent moisture absorption and maintain their effectiveness.
During winter, many farmers store leftover fertilizers from the previous year or purchase new ones for the upcoming spring season. However, some individuals lack proper knowledge about the properties of chemical fertilizers and may store them improperly, leading to reduced efficiency and potential hazards. Different types of fertilizers have unique characteristics—some are acidic or alkaline, others are corrosive or toxic, while some are highly hygroscopic, volatile, or even flammable. Therefore, it's essential to understand these properties and apply appropriate storage methods to avoid degradation and loss of effectiveness.
Chemical fertilizers should be stored separately in labeled containers, clearly indicating their names and compositions. Mixing certain types can lead to dangerous reactions. For example, ammonium-based fertilizers like ammonium sulfate, ammonium nitrate, and ammonium chloride can lose nitrogen when mixed with alkaline substances such as lime or lime nitrogen. Similarly, nitrate-based fertilizers like ammonium nitrate and sodium nitrate may dissolve when combined with superphosphate, causing nitrogen to escape as gas and reducing their value.
Fertilizers should be kept in dry, sealed areas to prevent moisture damage. Most fertilizers are water-soluble, and exposure to humidity can cause them to clump or liquefy, significantly reducing their effectiveness. Products like ammonium nitrate and ammonium bicarbonate are especially prone to moisture absorption and deliquescence, while others like ammonium sulfate and urea can form hard blocks when wet, making them difficult to use. When storing, avoid damaging the packaging, do not leave them outdoors, and protect them from rain, snow, and direct sunlight. It is recommended to place them on wooden pallets at least 0.3 meters above the ground and avoid stacking them too high.
Fertilizers should also be stored in cool, dark places. Nitrogen-based fertilizers are sensitive to heat, and excessive temperatures can cause nitrogen to convert into ammonia and escape, reducing their effectiveness. Ammonium nitrate, in particular, is highly flammable and explosive, so it must never be stored with flammable materials such as gasoline, alcohol, or sulfur. Proper handling and storage are crucial to ensure both safety and optimal performance.
Proper fertilizer management is essential for maintaining quality, preventing waste, and ensuring the safety of both people and the environment. Always follow manufacturer guidelines and take necessary precautions to avoid accidents.
