Increasing Your Growth Potential With Manvert Zn

The growth and success of young fruit and nut trees can be greatly influenced by one small element. One tiny detail that could take your new orchard from zero to hero. In 1926 zinc was found to be essential in green plants. In more recent years it’s been found to be especially beneficial in the healthy development of young trees. Zinc assists with healthy leaf development which in turn determines a tree’s growth rate. However, many soils across the world are either zinc deficient or not supportive of zinc uptake.

What does a zinc deficiency look like?

Zinc is an essential co-factor and precursor of essential amino acids in plants and is vital to healthy cell multiplication, growth and development.

A deficiency will often appear in new growth as:

  • Stunted growth.
  • A decrease in leave thickness.
  • Yellowing of leaves also known as chlorosis.
  • Twig die-back in trees.
  • Distorted leaves.
  • And in nut trees, the nuts can be poorly filled and dull.
  • Secondary damage such as plant disease and sun damage may occur as a result.

The problem with correcting zinc deficiencies

Zinc deficiencies only show up much later and then it is almost always too late to remedy. For this reason, it’s critical to be proactive about testing your soil before planting or then doing regular leaf analyses to determine the exact zinc requirement. Correcting zinc deficiencies require expertise as this element is not easily absorbed into the soil. As a result soil fertilizers formulated with zinc may not always be effective on young non-fruit carrying trees because they develop deep root systems that are unable to absorb the trace element.

Foliar sprays are then the next alternative, but this brings about its own problem. Zinc, as you might have deduced, is a bit of a lazy element and even when applied as a foliar spray it is not easily translocated in plants1. This then necessitates repeated spray applications (increased costs) and diminishes the ability of foliar sprays to alleviate Zn deficiency in all plant parts.

The DNA solution

Manvert Zn is a zinc deficiency corrector with a difference. Manvert Zn is formulated with the unique Lignovert Tech which is Manvert’s proprietary technology that allows for this treatment to be successfully applied as a foliar spray. The unique Lignovert Tech from Spain uses Lignosulphonic acid as a complexing agent to increase the availability of zinc to the tree as well as to enhance the uptake of the micronutrient. Due to the natural origins of this complexing agent (cellulose in wood), zinc is immediately released within the plant since the plant does not need to first break down the complexing agent, as is the case with most other complexing and/or chelating agents from chemical origin.

The sooner young orchards start receiving the correct dosage of Manvert Zn, the sooner they will begin to flourish. In the long-term this will result in healthier trees that deliver better quality fruit and nuts, and higher yields.
