Potassium stimulates the growth of strong stems and gives the plant some disease resistance by promoting thickness of the outer cell walls. Also, adequate potassium can reduce moisture loss from growing plants, thereby giving some drought resistance.
Potassium improves colour, flavour and storing quality of fruit and vegetables.
MOP is the most concentrated form of granular potassium and typically the most cost effective.
The even granule size of MOP allows for accurate spreading.
MOP is commonly blended with SSP to supply major nutrients for pasture based systems.
Muriate of Potash occurs as a natural salt and after processing to cleanse out unwanted salts (especially common salt), it is usually compacted into ‘chips’ and screened to meet size specifications.
MOP is used extensively for fertilising pastures, sugar cane, fruit trees, vegetables, and other field crops.
The product is packed in 25 kg and 50 kg laminated polypropylene bags with polyethylene liner and in 1000, 1200 and 1250 kg big-bags.
MOP stores well in bulk or in bags. It is not hygroscopic. MOP is particularly corrosive and so metal parts should be protected. After use, wash out equipment.
MOP is transported both packed (in bags, containers, transport packagings) and in bulk by all means of transportation, except by air, in accordance with cargo carriage regulations applicable to a particular transportation mode.
Guaranteed storage life: 6 months from the date of manufacture.
Restrictions:
MOP should not be used on salt sensitive crops, where soil salt levels are high or increasing, or where irrigation water has high salt levels.
Do not place MOP near seed unless the seed has been protected by lime-coating or inoculation.
Do not store in silos.
