Discover the benefits of foliar fertilizer application:
A small investment that leads to big results
Complementary nutrition
Application of foliar fertilizers is a must when soil fertilization is sub-optimal or ineffective.
In many farming practices most of the fertilizers for the growth season are applied as base dressing. Such practice often results in a significant decrease of essential nutrients in the soil during the season. This may affect plant growth and lead to reduced yield. Mid-season foliar sprays of fertilizers will balance and complete plant nutrition and help to retain healthy and fruitful growth. A relatively small amounts of fertilizers will lead to a dramatic improvement and will get the crops to optimal growth curves. This is a real Bonus. In some cases, uptake of nutrients by the roots may be impaired due to low temperatures, water logging, high humidity, nematodes, or other reasons. Here also, foliar nutrition is a true bonus, offering a beneficial complementary nutrition
Corrective nutrition
Foliar fertilizers are fast acting and effective for treating nutrient deficiencies.
Foliar uptake of nutrients is much faster than root uptake. Therefore, foliar feeding is the method of choice when deficiency symptoms are noted, and prompt correction of deficiencies is required. Nutrients rapidly absorbed through the foliage, providing the plant with the missing nutrients, and strengthening it.
Growth boosting
Foliar fertilizer application at precise timing leads to better growth and yield improvement.
Certain phases of plant development are highly important in determining the final yield. Foliar nutrition precisely given during these specific phenology stages ensures optimal growth, and best possible yield. In relatively low concentrations at these critical stages, foliar nutrition boosts physiological processes of the plant, ensures optimal development, and contributes significantly to higher yields and better quality.
Specific induction
Foliar fertilizers activate particular plant mechanisms.
Foliar application of certain fertilizers is known to induce dormancy breaking in grapes and deciduous fruit trees. They are also efficient in stimulating flowering, mainly in mango.
See below tips for successful foliar sprays.
Tips for a successful foliar spray
• After spraying rinse thoroughly, the sprayer and all its parts with fresh water
• If you apply smaller (or larger) volume than recommended, increase (or decrease) the fertilizer concentration of the spray solution accordingly, to keep the total application rate per unit of area.
• Avoid concentrated sprays, as they might scorch leaves.
• Plants in areas of humid climate tend to have thinner leaf cuticles, which make them more susceptible to phytotoxicity.
For this reason, spray concentrations must be considered more cautiously in these areas.
Preparation of tank mix• When preparing tank mix that includes pesticides, it is advisable:
- To keep the pH of the spray solution at level of 5.5 -6.5, to avoid alkaline hydrolysis of the pesticides.
Note: In general, Haifa’s foliar products are slightly acidic, requiring lower rates of acid to set the pH of the spray solution.
- Perform a compatibility test of the spray-mix prior to large-scale treatment.
