Plant Nutrition

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

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.

Multicote™ Agri Controlled Release Fertilizers are designed to feed agricultural crops continuously throughout the growth season – for optimal growth and yield production

Based on Haifa’s polymer coating technology, Multicote™ Agri release nutrients to the soil in a gradual manner, according to plant’s requirements. This prevents leaching of nutrients, thus improving nutrient use efficiency and allowing for reduced application rates.
 
Multicote™ Agri products are 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)

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.

The most reliable and effective way to make the availability of nutrients coincide with plant requirements is by controlling their release into the soil solution, using controlled release fertilizers. This is accomplished by encapsulating fertilizer granules in a polymeric coating, employing Haifa’s Multicote technology.

A single pre-planting application of Multicote™ controlled release fertilizer (CRF) can fill a crop’s nutritional requirements throughout its growth season. Multicote™ products are designed to feed plants continuously, at maximum nutrient uptake efficiency. Multicote™ controlled release fertilizers save labor and application costs, enable application independent of the irrigation system, and require no sophisticated equipment.

the controlled release fertilizers granules are applied to the soil, the coating acts as a semi-permeable barrier that allows continuous release of nutrients to the root zone.

The benefits of controlled release nutrition
Haifa Multicote controlled release fertilizer
  • Optimal plant development - provide plants with balanced nutrition, according to their needs, throughout the growth cycle. This ensures optimal development and maximum high quality yields.
     
  • Less fertilizers are needed - products release available nutrients at a rate that matches plant uptake. This minimizes fertilizer losses, and enables considerable reduction of application rates – up to 30%, as compared to conventional granular or liquid fertilizers.
     
  • Saves labor and time - A single application covers a crop’s nutritional requirements throughout its growth cycle. This saves labor and costs associated with fertilizer application. It also eliminates fertilization from the growers’ routine tasks, freeing them to concentrate on other growth requirements.
     
  • Simple application - fertilizers are applied directly to the soil, requiring no sophisticated injection or dosing system.  
     
  • Environmentally friendly - minimizes losses through leaching, volatilization or fixation, thus preventing environmental contamination.

The benefits of Haifa Micro™ - micronutrients fertilizer
  • All micronutrients are in a chelated form, to maximize stability and efficiency
  • Compatibility with a wide range of agrochemicals enables tank-mixing, thus reducing the cost of spray operations by minimizing the number of application needed
  • Haifa Micro™ chelates are absorbed by the plant rapidly and efficiently
  • Haifa Micro™ chelates are fully soluble in water
 
The mechanism of chelates
Chelate is a complex of a micronutrient ion and an organic molecule that "holds" it, called ligand. As long as the ion is attached to the ligand, it is protected from interacting with other ions in the solution, which might turn it unavailable for plant uptake.
 
As the micronutrient ions are consumed by the plant, more ions are released from the holding ligands, thus becoming available for plant uptake.
 
This mechanism maximizes the efficiency of the micro nutrients applied. When Haifa Micro™ is applied by Nutrigation™, the chelates ensure availability of micronutrients in both alkaline and acidic soils.
 
 
Iron (Fe) plays an important role in chlorophyll formation. It is involved in cell division that supports plant growth, and in other vital reactions in the plant.
