Talc has many natural properties (i.e., Anti caking, Dust prevention,
Die lubricant, Dispersing agent, Flow agent, Inert carrier, UV protector
etc) which are ideal for improving processing, productivity and the final
quality of agricultural products.
Fertilizers :
Talc make excellent coating agents preventing caking and dust.
Complex and nitrogen / phosphate fertilizers have a natural tendency
to cake. Caking can occur during both storage (in bulk or in bags) and
transportation. Caked fertilizer cannot be sold and has to be returned
to the manufacturer, resulting in a waste of time, materials and money.
Talc are used in both powdered and granular fertilizers where they
make excellent coating agents which:

Agriculture Application

  • prevent fertilizer caking - Talc’s smooth, flat lamellae cover each fertilizer granule, thus helping them to flow freely
  • reduce water pick-up - Talc is naturally hydrophobic and forms a barrier around the fertilizer granules which limits water pick-up
  • prevent the formation of hydrate crystal bridges - allowing products to be stored longer
  • Flow agent - Talc is inert and platy. Its smooth and flat lamellae cover each particle helping it to flow freely during fertilizer or feed production. It improves handling and drying, speeding up the packaging process.
  • protect against dust -Talc is inert, protecting the fertilizer against physical and chemical reactions which deteriorate granules, generating dust during prolonged storage.
Animal Feed :
Talc is inert and hydrophobic in nature.
Fruit Protection :
Talc is also used for protecting fruit crops (like Pears, Apples, Grapes etc) from UV rays and Sunburn. It reduces surface
temperature and prevent moisture loss.
Seed Coatings :
Talc is ideal for seed coatings due to its natural properties. It reduce abrasiveness and improve seed flow rate. It also
reduces over seeding and premature germination of seeds thus increasing seed shelf life.
