Rech Chemical Co. Ltd specializes in the production of ferrous sulphate monohydrate and ferrous sulfate heptahydrate. Ferrous sulphateis a byproduct of rare metal with sulfuric acid method, which appears gray or light green.

In Agriculture:
1.Adjust soil PH and effectively improve soil.
2.Supply ferrous element for the plants. Ferrous is a catalyst of making chlorophyll, which could prevent yellowing disease.
3.A pesticide to control plant lesions, as for wheat and fruit trees.
4. In gardening, ferrous sulfate is used to kill moss and lichen.

Water treatment:
1.Mainly used in water purification and industrial wastewater treatment. Add proper amount to adjust the PH value of alkaline water. Combined with ferrous sulfate, suspended solids in water could be accelerated precipitation.
2.Antiseptic effect.

Industry:
1.Ferrous sulphate is used in the manufacturing of salt, ink, iron oxide red and indigo, etc.
2.Used as mordant, tanning agents, disinfectants and detergents, wood preservatives, etc.

 Eggplant is one of common vegetable in our life. In its planting, right amount of manganese sulfate and other micronutrient fertilizer can improve the quality and yield. However, incorrect fertilizer application would cause pollutions on vegetables, even some affect to eaters.

Eggplant is a plant that needs more fertilizers and has strong fertilizing resistance. Basal fertilizers should be strengthened before ploughing, and at the same time, trace elements as zinc sulfate 1 kg and manganese sulfate 2 kg are suitable for each acre. As to ferrous sulphate, its amount can’t exceed 3.25 kg per mu. The amount of manganese sulfate, manganese chloride can't exceed 2.05 kg per month.

Vegetables usually demand very little for trace elements, and excessive application micronutrient fertilizer is not only wasteful, but also easy to produce harm to crops and pollution to the environment. So, every gardener in the practical use of micronutrient fertilizer, remember to fertilize according to the method of manganese sulfate and other micronutrient fertilizer fertilization

 In egg poultry cultivation, all sorts of symptoms without knowing causes may appear that lead to the symptoms such as egg production decrease, slow growth. In this case,zinc sulfate also should be added.

The nutrients: a. tocopherol, special effects add egg factor etc; b. trace element: manganese sulfate1~ 4g, zinc sulfate 1~ 4g, ferrous sulfate1~4g, copper sulfate300 ~ 500mg, sodium iodide 40~ 60 mg, selenium 10-30mg, calcium chloride70~ 90 mg, potassium dihydrogen phosphate 60~ 80 mg, salt 120 ~ 180 mg, niacin 2500~ 3500 mg, biotin 5~ 15 mg, choline 80 ~ 150 mg, linolenic acid 5 ~ 15mg, linoleic acid 2 ~ 8 mg, methionine 60 ~ 120 mg, selenium methionine 40~ 80 mg, lysine 10 ~ 50 mg, pantothenic acid 500 ~ 1000 mg, betaine 5 ~ 10 mg, phytase mgfyt 25000 ~ 35000FYT, compound enzymes 100 ~ 160 mg, antioxidants 20 ~ 30 mg; Water from 1000 to 3000 mg

Usage and dosage: mix with materials or water, stay for 20 ~ 30 minutes.

More micro minerals such as amino acid, zinc sulfate compound feeds can make the generation and enrichment of organic trace elements in poultry bodies and eggs, and indirectly improve the quality of people's diet and health.
