Multi-K™ potassium nitrate inside

Adequate potassium nutrition is essential for healthy growth, for the plant's strength and for excellent yield quality.
The potassium in Haifa Turbo-K™ is derived from Multi-K™ potassium nitrate, the best source of potassium for plants.

 

Combating soil salinity

High soil salinity impairs water uptake by the plant, thus disturbing critical physiological processes and consequently retarding growth and reducing yields. In addition, the main ions that produce salinity in the soil, sodium (Na+) and chloride (Cl-), have specific toxic effects on plants. 

Haifa Turbo-K™ is low in sodium and chloride, and possesses a low salt index. This makes it ideal for salt-sensitive crops and for use under hot, dry climates, where salinity problems are more severe.

 

 

Magnisal™ / Haifa MAG™ magnesium nitrate fertilizer provides plants with readily-available magnesium, which is essential for their healthy growth

 

The nitrate in Magnisal™ facilitates the uptake of magnesium by the plant, thus improving its efficiency. It also enriches plant nutrition with readily available, easily absorbed nitrogen.

Visit the product page for more information

 

Magnesium is essential for the plant

Magnesium is a vital nutrient for healthy plant growth. It is a key component of the chlorophyll molecule, hence essential for photosynthesis and formation of carbohydrates. Magnesium is involved in enzymatic reactions and assists in generation of energy. Magnesium deficiency retards plants development, resulting in decreased yields and poor quality.

 

Deficiency symptoms

Magnesium deficiency is manifested by yellow bands between leaf veins. The symptoms show first on older leaves, and move towards young leaves as deficiency worsens. In severe cases, necrosis may appear.

 

Magnesium deficiency in plants

 

 

The benefits of Magnisal™ - magnesium nitrate fertilizer

  • Prevents and cures magnesium deficiencies
  • Consists of 100% plants nutrients
  • Free of chloride, sodium and other detrimental elements
  • Dissolves quickly and completely in water
  • Ideal for efficient applications by fertigation and foliar spray

 

Magnisal™ is a superior source of magnesium

Magnesium nitrate is superior to magnesium sulfate fertilizers. It possesses higher nutritional value and better physical properties that make it more convenient for handling and application.

 

Plant nutritional value

Plants absorb the magnesium from Magnisal™ more readily, due to the interaction between the magnesium and the nitrate anion. Magnisal™ is up to three-fold more effective than magnesium sulfate in preventing and curing magnesium deficiencies, and therefor enables considerably lower
application rates.

Nutrigation™ with Magnisal™

Nutrigation™ (fertigation), delivery of pure plant nutrients through the irrigation system, is a highly efficient application method, enabling full control over rates, composition, timing and placement of plant nutrition.

Magnisal™ is ideal for Nutrigation™ of crops in both soil and soilless media. Pure and highly soluble, Magnisal™ is safe for use with all types of irrigation equipment. It is compatible with all water-soluble fertilizers, except concentrated phosphate solutions.

Magnisal™, unlike magnesium sulfate, can be used with water of poor quality, hence recommended when the irrigtion water contains high levels of sulfates or salts. In most irrigation practices, magnesium concentration in the water should range between 20-60 ppm.

The following table shows stock-solution levels and injection ratios needed to obtain specified magnesium concentrations in the irrigation water.

 

  Mg concentration in the irrigation water  
  20 ppm 40 ppm 60 ppm 80 ppm 100 ppm  
Stock solution Injection ratio  
25 kg / 1000 liter 8.3 16.7 25.0 33.3 41.7 Liter/m³

Note: data refer to magnesium (Mg) levels in the irrigation water, not to magnesium oxide (MgO).

 

Nutrigation™ of soil-grown crops

Determine Mg requirements according to soil and water analyses. If additional magnesium is required, apply 0.1-0.3 grams Magnisal™ per liter of irrigation water (1.3-4 Oz./100 gallon) per application.

 

Nutrigation™ in soilless media

For most crops, recommended magnesium concentration in the nutrient solution is 50-70 ppm MgO (30-40 ppm Mg). The magnesium level in the irrigation water should be taken into account. When the
Two-Tank method is employed, dissolve Magnisal™ in the tank that does not contain phosphorus (P).

The given recommendations should be regarded as a general guide only.

The exact fertilization program should be determined according to the specific crop needs, soil and water conditions, and the grower’s experience. For best results, follow the recommendation of a local crop consultant.

 

Magnisal™ for foliar applications

Foliar spray is an efficient tool to supplement and to enrich plant nutrition.
When absorption of nutrients from the soil is disturbed, foliar application of Magnisal™ provides the magnesium needed for normal development of crops.
When prompt correction of magnesium deficiency is required, foliar application is recommended, as uptake of magnesium by the leaves is very fast.

 

Preparation of tank-mix

Dissolve Magnisal™ in a small amount of water and add to the spray tank. When applying with cropprotecting agents, addition of wetting agent is not necessary. To ensure compatibility of tank-mix components, perform a small-scale test prior to actual application.

 

Foliar spray

To verify safety of suggested rates under local conditions and for specific varieties, it is recommended to spray on a few branches or plants. After 3-4 days check the tested plot for scorching symptoms.

When to use Multicote™ Agri
Multicote™ Agri is highly beneficial

  • On light soils, where conventional fertilizers are easily leached

  • In rainy areas, when rainfall accelerates nutrient leaching

  • Wherever nitrogen application is limited, e.g. by environmental regulations

  • For crops with a shallow root system

  • For crops with high nutritional requirements

  • In cases where mid-season application is not feasible (e.g. when the crop covers the soil surface, in mulched crops and in muddy fields)

Multicote™ Agri Junior – the best start for young orchards
 

Fertilization independent of irrigation
As Multicote™ Agri is applied directly to the soil, it depends neither on irrigation equipment nor water quantities. When excess irrigation is applied to prevent salinity build-up, soluble fertilizers given through the irrigation system are wasted. Multicote™ Agri prevents this scenario.
Multicote Agri™ also cancels the need for technical irrigation, given in rainy days just to provide nutrition. Thus, Multicote™ Agri saves bothers and water.

CoteN™ is Haifa's polymer coated Urea, set for 2 or 4 months longevity (@21C).
CoteN™ is perfect crops with special emphasis on N management in the soil, such arable crops.

 
CoteN™ is part of the Multicote range of Controlled Release Fertilizer (CRF), developed by Haifa Group. An accurate fertilizer release over time, governed only by soil temperature, make CoteN™ a precise and reliable N source for the crops.
 












 

The soil temperature factor

When the weather gets colder, the N release rate becomes slower. This meets the decrease in nutrients consumption by the plant. This CRF technology ensures both precise plant feeding, and efficient nutrition with s minimum loss of N to the soil. 

Once the weather gets wormer and plants demands for nutrients increase, and so the release rate of Urea from CoteN™.
 
Nitrogen is known to be illusive Nutrient. Urea, can Volatilize as Ammonia, or can be transform to Ammonium (NH4+) , then to Nitrite (NO2-) and Nitrate (NO3-). Ammonium (NH4+) can be uptake by the roots, and it can also be tied to the soil particles as they are negatively charged. Nitrate (NO3-), due to the negative charge cannot be tied to soil particles. It can be uptake by the roots, or it can be leached to groundwater. The speed of all these transitions is depends of the temperatures, water regime, soil type and the right bacterial groups present in the soil. CoteN™, Controlled release fertilizer is affected only by temperature. Similar to the effect that temperature has on plants.
 
 

The CoteN™ Advantages

Proven Cost effectiveness
  • A substantial reduced N level applied to the soil
  • Single application, no need to fertilize again during the season.
  • Save on labor and time
  • Lower fertilization costs per area
 
Precise plant nutrition feeding
  • Accurate N release following plant's nutrient uptake demand
  • Ensures constant N feed regardless of rainfall and irrigation rates
 
A sustainable  solution
  • Prevent nitrogen leaching to groundwater and keep a sustainable agricultural soil
     
 
 
NEW: CoteN™ Mix
Haifa also introduced the CoteN™Mix concept: a wide range of CoteN™ based blends, bringing the CoteN™ added values to mixes of uncoated fertilizers to complete the P & K needs.

Water soluble chelated micronutrients for Nutrigation™ and foliar application

  • Complement plant nutrition 
  • Facilitate growth and boost vigor
  • Correct deficiencies and cure mal functioning of the plant
  • Support flowering and fruiting
Intensive crop production calls for perfectly balanced nutrition that includes all plant essentials.
Special care is required when it comes to micronutrients, as their deficiency may impair plant growth. Even hidden deficiencies, with no visual symptoms, put yield levels and crop quality at risk. 
Haifa Micro™ products ensure adequate supply of micronutrients throughout the growth cycle. They are highly recommended for prompt correction of deficiencies when noted or detected.
 
Haifa Micro™ products dissolves fully and rapidly in water, which makes them ideal for Nutrigation™ and foliar application.



 
 



Micronutrient chelates improve stability and plant availability

For maximum stability and best availability for plant uptake, the micronutrients in Haifa Micro™ products are in the form of chelates.
A chelate is a complex of a micronutrient ion and an organic molecule (ligand) that "holds" it and protects it from interacting with other ions in the solution, which might make it unavailable for plant uptake.
As the micronutrient ions are consumed by the plant, more ions are released from the molecules that hold them and become available for plant uptake.
Due to their chelated form, the micronutrients in Haifa Micro™ are available for plant uptake in both alkaline and acidic soils.

The advantages of potassium nitrate
Haifa Bonus™ formulas are based on Haifa’s Multi-K™ potassium nitrate. Potassium nitrate contains 100% plant macronutrients: potassium (K) and nitrate-nitrogen (N-NO3). Plants absorb both the potassium and the nitrate rapidly, in a balanced manner. The similar uptake rates of these two ions improve the movement of both potassium and nitrogen in the plant, thus enhancing plant nutrition. Potassium nitrate is free of chloride, sodium and any other elements which are detrimental to plants.
