What effect does improper storage of chemical fertilizer have on crops?

Improper storage of chemical fertilizers will have a series of adverse effects on crops, including:

1. Nutritional imbalance: If the fertilizer is wet or stored improperly, it may lead to the loss or change of nutrient elements, so that the fertilizer applied to the soil can not provide balanced nutrition for crops and affect the normal growth of crops.

2. Burn crops: Some fertilizers, especially chemical fertilizers, may cause concentration changes if stored improperly, and may burn the roots or leaves of crops when used.

3. Soil salt accumulation: improper storage may lead to changes in fertilizer composition, which may cause soil salt accumulation after use, affecting soil fertility and crop growth.

4. Environmental pollution: If some components in fertilizer are lost to water due to improper storage, it may cause eutrophication of water and environmental pollution.

5. Reduce fertilizer efficiency: Improper storage conditions, such as humidity and high temperature, may lead to changes in the physical and chemical properties of fertilizers, thus reducing their fertilizer efficiency.

6. Causing pests and diseases: Improper storage of fertilizer may become a breeding ground for pests and diseases, and the use of this fertilizer may bring pests and diseases to fields and harm crops.

In order to ensure the quality and effect of fertilizer, it should be stored and used correctly according to the instructions of fertilizer manufacturers. At the same time, rational use of chemical fertilizer and organic fertilizer and popularization of soil testing formula fertilization can not only improve the yield and quality of crops, but also reduce the impact on the environment, which meets the requirements of sustainable development.

The correct storage of fertilizer is the key to ensure the quality and effect of fertilizer. Here are some suggestions on how to store fertilizers correctly:

1. storage environment:

Drying: Fertilizers should be stored in a dry environment to prevent moisture absorption and caking or changes in chemical composition.

Ventilation: Good ventilation can prevent fertilizer from getting wet and prevent the accumulation of harmful gases such as ammonia.

Shade: Avoid direct exposure of fertilizer to sunlight. High temperature may destroy the stability of fertilizer.

2. Classified storage: Different types of fertilizers should be stored separately to prevent cross-contamination. For example, nitrogen fertilizer, phosphorus fertilizer and potassium fertilizer should not be put together.

3. Stacking method:

Off the ground: pile the fertilizer on the wooden board about 10 cm off the ground to facilitate ventilation and prevent the ground from getting wet.

Covering: Cover the fertilizer with tarpaulin or plastic film to prevent rain and moisture from invading.

4. Good packaging: keep the original packaging of fertilizer intact. If the package is damaged, it should be resealed immediately or transferred to a new container.

5. Avoid contact: fertilizers should avoid direct contact with seeds, food, feed, etc. Prevent pollution.

6. Anticorrosion: Some fertilizers (such as ammonium nitrogen fertilizer) may corrode storage facilities, so appropriate containers or storage facilities should be used.

7. Safe distance: Fertilizer should be kept away from children and pets to ensure safety.

8. Instructions for use: According to the instructions for use and storage on the fertilizer package, different types of fertilizers may have different special requirements.

Following these storage guidelines will help to maintain the quality of fertilizers and ensure that they can exert the best effect when applied.

Different types of fertilizers do have some special storage requirements because of their different chemical properties. The following are special storage requirements for some common fertilizer types:

1. Nitrogen fertilizer:

Avoid mixing with alkali and lime to prevent ammonia volatilization and nitrogen loss.

Ammonium nitrogen fertilizer (such as ammonium sulfate and ammonium bicarbonate) should be stored in a dry, cool and ventilated place to avoid mixing with seeds and food.

Amide nitrogen fertilizer (such as urea) should be stored in a sealed way to avoid wet environment, because urea will release ammonia gas in wet environment.

2. Phosphate fertilizer:

Phosphate fertilizer is usually relatively stable, non-volatile and non-decomposed, but it should avoid humid environment and prevent moisture absorption and caking.

The storage temperature of phosphate fertilizer should not be too high, so as not to affect its solubility and effectiveness.

3. Potash fertilizer:

Potassium fertilizer should also be stored in a dry environment to avoid moisture absorption.

Potash fertilizer is similar to nitrogen fertilizer and phosphate fertilizer, so contact with alkaline substances should be avoided.

4. Compound fertilizer:

Compound fertilizer contains a variety of nutrients, and its storage requirements are usually a combination of various single fertilizer requirements.

Pay attention to prevent fertilizer from absorbing moisture and caking, and keep the packaging intact.

5. Organic fertilizer:

Organic fertilizer should be stored in a dry and ventilated environment to prevent mildew and fermentation.

Organic fertilizer may produce odor during storage, so it needs good ventilation.

Rain soaking should be avoided to prevent nutrient loss.

6. Liquid fertilizer:

Liquid fertilizer should be stored in a sealed container to prevent evaporation and overflow.

Direct sunlight should be avoided to prevent the pressure of the container from rising due to temperature rise.

Storage containers should be placed on a stable ground or shelf to prevent dumping.

7. Microbial fertilizer:

Microbial fertilizer should be stored in a cool, dry and ventilated environment to avoid high temperature and humidity, so as to prevent the number of living bacteria from decreasing.

Avoid mixing with fungicides or fertilizers for use and storage.

When storing any type of fertilizer, we should abide by local environmental protection laws and safety standards to ensure the quality of fertilizer and protect the environment and human health.
