Agenda

Foliar Feeding

Fundamentals and advantages

Proven Added Value

Results of five field trials results and practical conclusions

The Haifa Way

Advanced Foliar Feeding products by Haifa

Foliar Feeding – why and when

Complementary fertilization

Giving the crops a bonus with a significant added value. Not replacing soil fertilization.

Corrective nutrition

Intensive Care - when deficiencies are noticed

Growth boosting

During critical stages of plant development

For Special Jobs

  • Dormancy breaking (in vineyards and deciduous trees)
  • Flower induction (in mango)

Foliar Feeding

plant roots

Foliar feeding induces intensive activity of all plant parts,

thus enhancing also root uptake

Fertilizers suitable for Foliar Feeding

Water soluble N-P-K  in various ratios

Enriched with secondary or micro plant nutrients

Has good physical properties

For improved fertilizer adhesion to the leaf, and to release nutrients over a prolonged period of time.

Brazil: Increasing yields and plant health in Soybean

For 2 decades Haifa has conducted a range of field trials on foliar application of Haifa Bonus™ in Argentina and Brazil. These trials have shown:

Soybean positively responds to foliar fertilizer

More notable response under sub-optimal conditions

Healthier plants, more resistant to pests and diseases

Plants suffering less stress during drought periods

At least 5% more pods per plant

Average weight of the grains, up to 5% heavier Up to 15% higher yields

The experiment was carried out in cooperation between  Research

Foundation Rio Verde - Mato Grosso State and Haifa in 2013.

Foliar fertilization reduces splitting and creasing in citrus, Israel

‘Nova’ tangearine and ‘Washington’ navel orange in Israel suffer from peal splitting, causing fruit loss of up to 50,% and from creasing, disqualifying the fruit for fresh marketing.

The trial studied the effects of naphthaleneacetic acid (NAA 300mg/L), tank-mixed with Haifa Bonus™ at 5%

Foliar fertilization reduces splitting and creasing in citrus, Israel

NAA+ Haifa Bonus™ spray on large fruitlets (30 mm) reduced creasing by 30%

Common spray with GA (20 mg/L) in August reduced creasing by 20%

In both varieties NAA sprays produced larger with no effect on fruit number or yield

Foliar application of NAA + Haifa Bonus™ reduced creasing and splitting

Treatment had no significant effects on the % juice, total soluble solids and acid content
