AgSector Salt Sales
• Pacific Brand (Industrial)
– Bulk Salt, 1000/1200Kg bulk bags, 25kg sacks
– To fertilizer companies, mineral suppliers, stock
food manufacturers, concentrate/premix
suppliers
– Mainly truck and trailer unit deliveries.
• Summit Brand (Retail)
– Salt blocks, loose salt licks, salt in 25kg sacks
– Only sold through rural retailers
– Single pallet distribution
Bag Configuration / Grade Types
• 1.0 /1.2T bulk bags
25kg bags (1.2T/pallet)
• Solar salt varies little
chemically, although
have a wide range of
crystal sizes available
• Pallets are returnable
on a charge/credit basis
Salt in Agriculture
• Sodium (Na) is vital for animals but is not
necessary for plant mineral nutrition
• Low sodium in the diet is production limiting
• The soil in many regions of NZ is naturally low in
sodium
• Salt supplementation in low sodium
environments pays:
– In a dairy trial at Waikete Valley in 2000, $1 of salt
returned $33 of additional milk, in 2013 - $1:$70
(AgResearch - Ruakura Research Centre)
– For sheep and beef on lucerne (1973/4), $1 of salt
would return $10 of extra production in 2013 (Ag
Research Wairaki)
Salt is critical to a nutritionally
balanced diet:
• Sodium is required for absorption of glucose
and most amino acids, and low Na can lead to
reduced phosphorus and magnesium
absorption
• Chloride is required for hydrochloric acid
production
• Supplementing livestock rations with salt will
encourage optimum weight gain, milk
production and performance
