murate of potas 3 marks

Answer 1

Features and benefits

Potassium stimulates the growth of strong stems and gives the plant some disease resistance by promoting thickness of the outer cell walls.

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

2. Manufacture

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.

3. Uses

MOP is used extensively for fertilising pastures, sugar cane, fruit trees, vegetables, and other field crops
