Harvest Zinc Project

ADOB company has joined The Harvest Zinc Fertilizer Project, which is an international initiative developed under Harvest Plus Program.
Micronutrient malnutrition affects billions of people. It is caused by lack of micronutrients in daily diet. An average diet consists mostly of a few inexpensive staple foods, which have few micronutrients. The consequences of malnutrition are devastating and can result in blindness, stunting, disease, and even death.
HarvestPlus seeks to reduce malnutrition and provides micronutrients to billions of people directly through the staple foods which they eat. It uses a novel process called biofortification to breed crops with higher levels of micronutrients wich can enrich daily diet.
HarvestPlus focuses on three critical micronutrients that are recognized by the World Health Organization (WHO) as the most limited in diet: iron, zinc, and vitamin A. HarvestPlus forsees that in fifteen years, millions of people suffering from micronutrient malnutrition will be eating new biofortified crop varieties.
HarvestPlus Challenge Program was officially launched in 2004 when it financial support for biofortification research by Bill and Melinda Gates Foundation. Over the past years has also received funding from many other generous entities.

“Two billion people in the developing world suffer from diets lacking essential vitamins and minerals.”

HarvestZinc Fertilizer Project was developed under HarvestPlus Program and was launched in April 2008. This project seeks to explore and test fertilizer use in order to improve Zn concentration in various staple food crops, particularly in wheat and rice.

Biofortification of cereal grains, by the use of Zn fertilizers, enables to increase Zn concentration in staple food crops. It is essential for keeping sufficient amount of available Zn in soil and maintaining adequate Zn transport to the seeds during reproductive growth stage.
In many crop plants, hidden zinc deficiency has been well documented as the one responsible for reduction of yield up to 20 % without appearance of distinct leaf symptoms.
It is therefore important that commonly applied fertilizers would contain available zinc in order to prevent plants from Zn deficiency stress. Dietary Zn deficiency is believed to cause human Zn deficiency which is closely linked with soil Zn deficiency .

The activity of Harvest Zinc Project is based on three main objectives:

  • to test the role of Zn-containing N-P-K fertilizers for increasing root Zn uptake and improving grain Zn concentration
  • to identify the most effective foliar Zn application time and method for promoting leaf Zn uptake and maximizing Zn accumulation in grain
  • to collect information on the role of Zn-containing fertilizers in improving grain yield and
  • to increase capacity building through close cooperation and dissemination activities among scientists, agronomists, extension staff and local farmers in the selected target countries.

Under Harvest Zinc Project there are numerous field trials deployed in seven countries:
Brasil, China, India, Pakistan, Thailand, Turkey, Zambia.
ADOB delivered Zn fertilizers for the purpose of trials : Zn HBED and ADOB® Zn IDHA.

Harvest Zinc Project is also a successful global partnership which seeks a short-term solution to well-known zinc deficiency problem in human nutrition and also in crop production.

Therefore many entities agreed to take part in this project and support it – among them ADOB.
