Micronutrients

The Borrechel® product line utilizes lignosulphonate as a polymeric complexing agent. The non-phytotoxic nature of these complexing agents makes them the perfect choice for soil and/or foliar application of copper, iron, magnesium, manganese and zinc.

With Borregaard LignoTech’s extensive line of micronutrient products, a specialty fertiliser supplier is able to provide formulations that are suitable for a variety of applications in agriculture. Our products are relatively gentle compared to otherwise complexed and chelated formulations, helping to minimise leaf burning in foliar spray applications. They can also help to provide suitable micro-nutrition for citrus, grapes, and other fruits and vegetables when used in the appropriate manner.

Products offered in this line are

• Borrechel FE 853: 11.6% complexed iron in spray dried powder form.
• Borrechel CU 850: 12.6% complexed copper in spray dried powder form.
• Borrechel MN 852: 12.6% complexed manganese in spray dried powder form.
• Borrechel ZN 851: 12.6% complexed zinc in spray dried powder form.
• Borrechel COMP 854: 4.2% complexed iron, 1.1% complexed copper, 2.6% complexed manganese and 2.6% complexed zinc in spray dried powder form.
• Marasperse® AG:  Lignosulphonate-based complexing agent for use in formulating micronutrients from their sulphate salts.

Compatibility

Borregaard LignoTech’s micronutrients are usually compatible with urea and/or ammonium nitrate based liquid fertilisers. In such cases, they can be applied with the fertiliser in a single application.

It is recommended that our micronutrients not be used in high phosphate fertilisers without first testing compatibility in such systems.

TSCA Listing

Borrechel micronutrients and Marasperse AG® are listed in the Toxic Substances Control Act inventory.

Application Guidelines

Borrechel CU 850 - Copper is needed for chlorophyll formation in plants. Organic soils and alkaline soils are most likely to be copper deficient.

• As foliar spray for oranges - 0.57 kg metal/hectare (½ pound metal/acre)
• For sugar beets - 1.14 kg metal/hectare (1 pound metal/acre)
• Fruits in general - 1.14 kg metal/hectare (1 pound metal/acre)
• Tomatoes - 0.57 kg metal/hectare (½ pound metal/acre)

Borrechel FE 853 - Iron is a catalyst for chlorophyll formation in plants. It also acts as an oxygen carrier. In alkaline soils, Borrechel Fe 853 should be applied as a foliar spray.

• As foliar spray for oranges - 0.57 kg metal/hectare (½ pound metal/acre)
• For sugar beets - 1.14 kg metal/hectare (1 pound metal/acre)
• Fruits in general - 1.14 kg metal/hectare (1 pound metal/acre)
• Tomatoes - 0.57 kg metal/hectare (½ pound metal/acre)

Borrechel MG 845 - Magnesium is a constituent of chlorophyll formation and is actively involved in photosynthesis.

• As foliar spray for oranges - 2.27 kg metal/hectare (2 pounds metal/acre)
• For sugar beets - 5.68 kg metal/hectare (5 pounds metal/acre)
• Fruits in general - 5.68 kg metal/hectare (5 pounds metal/acre)
• Tomatoes - 1.14 kg metal/hectare (1 pound metal/acre)

Borrechel MN 852 - Manganese functions primarily as part of plant enzyme systems.

• As foliar spray for oranges - 3.40 kg metal/hectare (3 pounds metal/acre)
• For sugar beets - 6.82 kg metal/hectare (6 pounds metal/acre)
• Fruits in general - 6.82 kg metal/hectare (6 pounds metal/acre)
• Tomatoes - 1.70 kg metal/hectare (1.5 pounds metal/acre)

Borrechel ZN 851 - Zinc aids synthesis of plant growth substances and enzyme systems.

• As foliar spray for oranges - 3.40 kg metal/hectare (3 pounds metal/acre)
• For sugar beets - 6.82 kg metal/hectare (6 pounds metal/acre)
• Fruits in general - 6.82 kg metal/hectare (6 pounds metal/acre)
• Tomatoes - 1.70 kg metal/hectare (1.5 pounds metal/acre)

The above dosages are suggested guidelines only. Actual usage rates should be based on reliable soil tests and plant analyses and on the advice of your field representative.
