Ammonium molybdate is an inorganic compound consisting of ammonium and molybdic acid salts. This compound is also known as ammonium molybdate. It is obtained by beneficiating molybdenum-containing ores. These ores are then roasted and leached with an aqueous ammonia solution. In the next step, the compound is purified and recrystallized.
What is the composition and formulation of molybdenum fertilizer?
The product is available as ammonium and molybdic acid salts. This substance has the formula (NH4)2MoO4. In this form, the compound is easily absorbed by plants. The product is produced as a colorless crystalline powder that dissolves readily in water.
Ammonium molybdate is available in various packaging sizes—3 grams, 1 kilogram, or 25 kilograms. This allows you to purchase the right amount depending on your intended use. This formulation is suitable for vegetables, fruit crops, and indoor flowers. It is suitable for use in both garden plots and large farms.
Purpose
Ammonium molybdate is a water-soluble micronutrient fertilizer available as a concentrated substance. Its use helps achieve the following effects:
- increase resistance to weather factors – plants become less susceptible to high temperatures and drought;
- improve the formation and development of crops;
- prevent rapid fading;
- avoid anomalies in the foliage structure.
Plants tolerate both a molybdenum deficiency and an excess of it poorly. Excessive amounts of the substance in plant matter can be harmful to humans and animals. Therefore, when applying fertilizer, it is important to strictly follow the instructions.
Ammonium molybdate is acceptable for use on the following plants:
- vegetables;
- cereals;
- annual and perennial herbs;
- legumes that are grown in pastures and used for animal feed.
Terms of Use
If molybdenum is deficient in the soil, it can be applied in the spring or fall. The recommended dosage is 2-3 kilograms per hectare. If the product was applied to the soil, do not treat the seeds with it.
In other cases, seed treatment is acceptable. However, the following dosages must be followed:
- 30-50 grams per 1 centner of grains of vetch, soybeans, peas and other plants with large seeds;
- 500-800 grams per 1 centner of clover, alfalfa and other small-seeded plants;
- 60 grams per 1 hectare of vegetable plants with large seeds;
- 100 grams per 1 hectare of vegetable crops with small seeds.
When applying foliar fertilizer, a number of rules must also be followed. In this case, it's recommended to consider the plant type:
- Field crops. For aerial application, apply 100 liters of the product per hectare. For ground spraying, use 300-400 liters per hectare.
- Fruit trees, berry bushes, and vineyards. For these, a 0.01-0.05% solution is recommended. For this, use 10-50 grams of the solution per 100 liters. Apply the solution until the leaf surface is completely wet.
The use of ammonium molybdate helps increase yields by 20-30%. This treatment is highly effective and cost-effective. It can be used by both private farms and large agricultural enterprises.
Safety precautions
The compound belongs to hazard class 3. It is nonflammable and nonexplosive, and does not form harmful compounds with other elements. However, inhalation or ingestion of dust can negatively impact human health. The compound can accumulate in bone tissue, kidneys, and liver. It can irritate the skin, respiratory system, and mucous membranes of the eyes.
To prevent the substance from causing negative consequences, certain rules must be followed when using it:
- Wear protective clothing and personal protective equipment. This includes goggles, a mask, and a respirator.
- Avoid eating, drinking, and smoking while working. This is an important rule that will protect you from accidental ingestion.
- If the substance enters the respiratory system, move to fresh air and consult a doctor.
Ammonium molybdate can be transported using various modes of transport. It must be kept in sealed packaging. In most cases, tightly sealed polyethylene bags are used for this purpose.
Is compatibility possible?
Ammonium molybdate is compatible with most micronutrient fertilizers. It can also be combined with any pesticide. However, when preparing the working solution, it is important to first evaluate the compatibility of the selected products.
How and how long to store
The instructions state that the medication can be stored for 3 years. However, it's important to follow these guidelines:
- keep the composition in closed bags or containers that are appropriately labeled;
- store the substance in a dry place that is protected from ultraviolet radiation;
- Keep the drug away from food and feed.
It is recommended to store the product out of reach of children and pets. Also, do not allow unauthorized persons to enter the room containing the product.
What to replace it with
There are no exact analogues of this substance. However, molybdenum can be used in other forms that are absorbed by crops.
Ammonium molybdate is an effective product that can be used to improve plant growth and increase yields. This product only produces the desired results when the instructions are strictly followed. Therefore, it is crucial to adhere to the optimal dosage.
