Foliar Nutrition- an extra Bonus for the rice grower

About 80 million ha of irrigated lowland rice is mainly cultivated as flooded fields.

The unique properties of flooded soils make rice nutrient management different from any other crop.

Foliar Nutrition- an extra Bonus for the rice grower

When the soil is flooded, major chemical changes occur.

These changes influence nutrients availability to plants.

  1. Chemical reduction of soil.
  1. Decrease in concentrations of water-soluble Zn and Cu.

How Foliar Nutrition can improve nutrient management in flooded soils?

Foliar feeding is an effective method for overcoming the flooded soil special condition:

 

Nutrients are

increases the rate of the

absorbed directly

photosynthesis in the leaves

where they are needed

 

stimulate nutrient absorption by plant roots

Foliar nutrition applied at critical times correct deficiencies immediately and help maximizing yields and quality.

What Foliar Fertilizer is good for rice ?

Available in various N-P-K ratios.

Enriched with secondary (Mg) or micro (Zn) plant nutrients.

Has good physical properties, to improve adhesion of the fertilizer to the leaf surface and to release nutrients over a prolonged period of time.

Free of chloride.
