Manganese sulfate: instructions for use of sulfate fertilizer with the formula MnSO4 and color

Manganese is one of the elements necessary for the life of plants. Its deficiency leads to violations of the processes of growth and development. Consider the physical and chemical basic properties of manganese sulfate, the advantages and disadvantages of fertilizer, how to use it in agriculture. What methods of application exist, safety measures that must be observed when working with the drug.

Physical properties

Manganese sulfate has another name - manganese sulfate. This fertilizer contains manganese and sulfur. Crystalline uncolored substance. The content percentage of the active element is 19.9%.

It dissolves well in water, at 25 °C 64.8 g of powder dissolves in 100 g of water. This is a toxic compound that causes dangerous poisoning if ingested, dermatitis and eczema if it comes into contact with the skin.

Chemical properties

Manganese sulfate belongs to the group of s alts, it is a compound of manganese and sulfuric acid. Denoted by the formula MnSO_{4. Reacts with ammonia hydrate and alkalis.}

Pros and cons

Benefits of using manganese sulfate as a fertilizer:

• used to restore manganese levels in the earth;
• can be used on all crops and all soil types;
• combines with fertilizers containing essential nutrients;
• 15% increase in yield in the 1st season of use;
• increases the sugar content of vegetables and fruits, in the grain - the content of starch;
• 10-15% longer shelf life;
• stimulates the growth of generative shoots.

Disadvantages: if overdosed, a large amount of manganese can worsen the condition of plants.

Agricultural applications

Manganese sulfate is used as top dressing throughout the season, for all crops. It is combined with fertilizers containing nitrogen, phosphorus, potassium, and is applied in greenhouses as the main one. In combination with fertilizers, it is applied in the fall to the ground before sowing cereals, in which case it shows high efficiency.

The main purpose of the drug is to regulate the content of manganese in the soil and provide plants with this element. The lack of an element is observed in almost all regions and soil types, and what is present is often in hard-to-reach forms.

Weakened growth of roots, chlorosis due to slowing down of photosynthetic processes and disruption of chlorophyll formation, weak flowering, burns, development of spots can indicate an element deficiency.

Fertilizer is applied under plants that are at all stages of development. Due to the crystalline structure, it spreads rapidly in the ground. It acts gradually, the effect is stretched for a long time. Fertilizer is used economically.

After applying manganese sulfate on sugar beets, the volume of harvested root crops increases, they become sweeter. Growth of fodder grasses amplifies, the volume of mowing increases. An increase in yield is also noted on vegetables.

When applying fertilizer to grapes growing on alkaline carbonate soils, yields also increase, and the quality of berries improves. When used on fruit and berry crops, the fertilizer has a positive effect on the condition of plants, increases productivity, makes fruits and berries sweeter, and the content of vitamin C increases in them.Cereals, cotton and corn for silage also respond to fertilization by increasing yields, sugars, vitamins, protein, gluten and fats in grains and leaves.

Manganese sulfate can be applied on all types of soils, in all climatic conditions. Chernozem and sod-podzolic soils are especially in need of this element. They contain the element in the form of poorly soluble compounds. On forest soils, chestnut and alkaline, slightly alkaline chernozems, sulfate is applied for cereals, root crops for food, potatoes, sugar beet, alfalfa and corn, vegetables, citrus fruits, berry bushes and trees.

Feeding methods

Manganese sulfate can be used alone to quickly restore the content of the element in the soil. In most cases, it is used together with other fertilizers. Used for watering under the root and spraying on the leaf on crops growing in open beds and in greenhouses.

The dosage of the fertilizer may be different, depending on the crop and the condition of the soil, that is, on the initial content of manganese in it. Average dosage: 5-10 g per 10 liters.

The working solution must be prepared according to the scheme: water is added to the required volume of the preparation, everything is stirred. It is necessary to water or spray the plants with a fresh solution, choose calm and dry weather for processing, work during the day or in the evening. Spray the plants until the foliage is completely wet.

Safety precautions

The toxicity of manganese sulfate makes it a dangerous compound. If the substance gets inside, it can cause severe poisoning, there is a toxic effect on the digestive and nervous systems, the brain. The skin can also be damaged if a powder or concentrated solution comes into contact with it. At the site of contact, dermatitis can form, which is difficult to treat.

When starting to work with the drug, you need to wear long sleeves, gloves, goggles and a respirator. Prepare the solution in a ventilated area or outdoors. Store mineral fertilizer in sealed packaging. The powder should not be exposed to moisture, light, too low or high temperature.

Manganese sulfate is used as a fertilizer when it is necessary to quickly solve the problem of manganese deficiency in the soil. It can also be applied in combination with basic fertilizers for all crops, as top dressing throughout the season. Requires accurate dosing and application at recommended application rates.
