Foliar Feeding
Foliar Feeding provides fast, on-the-spot supplementary nutrition to ensure high, top quality yields and is an ideal feeding method under certain growth conditions in which absorption of nutrients from the soil is inefficient, or for use on short–term crops. Precision-timed foliar sprays are also a fast-acting and effective method for treating nutrient deficiencies. Foliar application of the correct nutrients in relatively low concentrations at critical stages in crop development contributes significantly to higher yields and improved quality. Haifa offers a selection of premium fertilizers for foliar application. Haifa offers a selection of fertilizers for foliar application:
Haifa Bonus™ High-K foliar formulas enriched with special adjuvants for better absorption and prolonged action.
Poly-Feed™ Foliar NPK formulas enriched with micronutrients specially designed to enhance the crop performance during specific growth stages.
Magnisal™, Haifa MAP™, Haifa MKP™, Haifa Cal™ and Haifa Micro™ are also suitable for foliar application.
Controlled Release Nutrition
Multicote™, Haifa's range of Controlled Release Fertilizers includes products for agriculture, horticulture, ornamentals and turf. Multicote™ products provide plants with balanced nutrition according to their growth needs throughout the growth cycle. Multicote™ products enhance plant growth, improve nutrients use efficiency, save on labor and minimize environmental impact.
Single, pre-plant application controlled-release fertilizer can take care of the crop’s nutritional requirements throughout the growth season. Controlled release fertilizers are designed to feed plants continuously, with maximal efficiency of nutrients uptake. Controlled release fertilizers save labor and application costs. Their application is independent of the irrigation system, and does not require sophisticated equipment.
Taking advantage of MulticoTech™ polymer coating technology, Haifa produces Multicote™ line of controlled release fertilizers.
Multicote™ Products
Multicote™ for nurseries and ornamentals; NPK formulae with release longevities of 4, 6, 8, 12 and 16 months.
Multicote™ Agri / Multigro™ for agriculture and horticulture
CoteN™ controlled-release urea for arable crops
Multicote™ Turf / Multigreen™ for golf courses, sports fields, municipals and domestic lawns.
