The substance can be absorbed into the body by inhalation of the aerosol and by ingestion.


A nuisance concentration of airborne particulates can be reached quickly upon dispersal.


Short-term effects

May cause mechanical irritation. The substance can cause effects on the blood when ingested, leading to the formation of methemoglobin. Effects may not appear immediately. Medical surveillance is recommended.

Environmental protection measures

During the handling of the product, do not pollute the air, soil, rivers, lagoons, streams, dams, channels or water reservoirs by not washing or pouring residues of plant nutrients or empty containers. Handle the empty container and its waste as established by the general law for the prevention and comprehensive management of waste.

The amount of Mg Nitrate to apply in the sowing field depends on the type of crop, type of terrain, climate and yield goal. Mg Nitrate can be dissolved and used in foliar applications. It is also used as a supplement in animal feed. Its application to the ground can be manual or mechanical. The nitrogen makes plants more succulent and dark green; promotes vegetative development and promotes the formation of good quality foliage, facilitating the formation of carbohydrates. Chemical analysis of the soil is recommended to assess fertility.

Cautions and Warnings

Avoid direct contact. Wear appropriate protective equipment to safely carry out product handling, preparation and application operations. Long-sleeved shirt and polyester and / or cotton pants, fabric gloves with PVC dots, disposable dust mask and industrial-use shoe with a rubber sole that covers the ankle. In case of contamination, change your clothing and throw away the contaminated clothing. Do not smoke, do not eat and do not drink during handling and application.

First aid

In case of contact with the eyes and / or skin, wash with running water for 15 minutes. If irritation persists seek medical attention. In case of inhalation move immediately to fresh air. In case of ingestion drink water or milk. In case of poisoning take the patient to the doctor and show him the label.

Storage and Transportation Conditions

If transported in bulk, do so in large capacity hoppers. If transported packed, do so in trailers or trucks with clean boxes. Store in covered and moisture-free places. Do not store more than 6 meters. Tall.
