Greenhouses

Soilless greenhouses represent the edge of horticulture technology.

At Haifa we know the challenges farmers are facing while growing  at soilless greenhouses: Small volume of growth medium and water with low capacity to retain plant nutrients require.

perfect match of plant nutrition to the crop growth needs.

Haifa has developed a pioneering range of soluble fertilizers that provide soilless crops with precise nutrition, maximizing yields and profitability.

Haifa's nutritional solutions precisely meet your crop's needs at any growth stage. Haifa specialty products are composed pure plant nutrients, and they are free of chloride or sodium. Thanks to Haifa’s innovative products, the water pipes and drippers will remain 100% clean and efficient. Decades of research and worldwide activity, have made Haifa a genuine expert in plant nutrition,  from development to supply and application. Haifa Group - Advanced Nutritional Solutions  for Soilless Crops

 

 

Modern fertilizers facilitate greenhouse maintenance

Modern greenhouse growers are facing the challenge of providing efficient plant nutrition while recycling drain water and keeping the watering pipes clean. With the right fertilizers, these goals can be fully achieved.

 

                                                         ♦ Keeping sodium out of the system

Plant nutrition used in soilless and hydroponic greenhouses must be efficient, precise, and contain only essential nutrients. Non-beneficialelements may accumulated in recycled drain water systems, change factors as pH and EC levels, and put the crops in risk.
Following an EU legislation which forces growers to recycle 100% of the waste water, Haifa has developed Multi-K™ Reci, a near-zero potassium nitrate that ensure low sodium levels in recycled drain water. Most plants won’t take up sodium. Therefore sodium concentration in the feeding solution will increase in time, and may harm the crops. 
With a maximum value of 300 ppm sodium, Haifa Multi-K™ Reci contains up to 90% less sodium than any other potassium nitrate fertilizers in the market. It prevents the increase of sodium levels in the feeding solution, and by that ensure healthier crops.

 

                                                     

               

               ♦ Highly efficient Phosphorus source

Phosphate in traditional fertilizers (MKP, MAP) is in the form of orthophosphate, and can easily form a compound with calcium, magnesium and iron, causing precipitation in the system. It is then no longer available for the plant and can even cause clogging. An increase of phosphate won’t improve the availability for the plant as this precipitation reaction increases.

Haifa VitaPhos-K™, a special polyphosphate based fertilizer, enables a true improvement in the growing results. Haifa VitaPhos-K™ improves
Phosphorus uptake and also boosts plants vegetative growth. The phosphate in VitaPhos-K™ remains stable in the feeding solution at high
pH and does not lead to any precipitation with other elements at high concentrations. The polyphosphate even ensures that precipitated elements will be re-dissolved, thus achieving improved efficiency of the elements provided.

 

 

 

             

                                                         ♦ Keeping irrigation system clean

After the introduction of polyphosphate, many growers have noticed that while higher dosage of polyphosphate give extra vegetative growth to the plants, polyphosphate in low dosage, keeps the irrigation system clean from participant. However, the relatively high pH of the product creates a need of adding acid into the fertilizer tank. Haifa’s new GrowClean™ eliminates this need. Haifa GrowClean™ contains 50% polyphosphate but the
pH of the product is neutral, so there is no need to add acid. Haifa GrowClean™ is also sodium-free
making it a good product for keeping the irrigation system clean, and at the same time 100% safe
for plants. With no mineral deposits, all mineral elements are available for the crops.

 

 

 

 

                                                          ♦ Stable pH levels with low-ammonium calcium nitrate made possible

In soilless growth media and hydroponics, nutritional solution’s pH must be carefully balanced. Any uncontrolled addition of ammonium to the solution will lower the pH in the root zone to an adverse level. In addition accelerated uptake of ammonium by the plant may result in toxic effects.
With near zero ammonium level Haifa Cal™ Prime is virtually free of ammonium, thus ideal for soilless crops. Haifa Cal™ Prime assures safe supply of essential calcium with no harmful side-effects and is more concentrated than other calcium nitrate products; therefore application volumes can be significantly reduced while the plants enjoys optimal calcium nitrate levels and the grower benefits from direct saving on
energy and labor.

Hydroponic Lettuce Handbook

Abstract: This hydroponic greenhouse production system was designed for small operations to provide local production of head lettuce as well as employment to the proprieters. Our research group has experimented with many forms of hydroponics but have found this floating system to be the most robust and forgiving of the available systems.
