Aqua-Tech
FERTIGATE WITH CONFIDENCE®


Overview

Aqua-Tech® is a delivery technology designed for innovative producers seeking greater plant productivity and ease of use for nutrients applied through fertigation systems.  Aqua-Tech® is unsurpassed in preventing hard water tie-up which leads to scale formation and nutrient unavailability.  Aqua-Tech® delivers highly available low-salt nutrients safely and precisely in conjunction with a unique polyamine technology that works to eliminate phosphorus tie-up in most cases.


What is Aqua-Tech®?

NACHURS Aqua-Tech® technology contains a patent pending polyamine molecule with proprietary additives and compatibility agents which helps protect phosphorus against adverse interaction with metals (calcium, iron, aluminum, etc.) and bicarbonates which may be contained in irrigation water sources. Products selected for this line have unsurpassed nutrient solubility and plant availability. It is still recommended to follow traditional compatibility tests to determine potential for system plugging:

  1. Add drops of the liquid fertilizer to a sample of the irrigation water so that the concentration is equivalent to the diluted fertilizer that would be flowing in the lateral lines.
  2. Cover and place the mixture in a dark environment for 12 hours.
  3. Direct light beam at bottom of container to determine if precipitates have formed.



Water Quality

Emitter plugging can result from physical (grit), biological (bacteria and algae), or chemical (scale) causes. Frequently, plugging is caused by a combination of more than one of these factors.

Water sources currently used for flood or mechanized irrigation are generally suitable for drip irrigation and “nutrigation”. However, there are some special considerations that are required to ensure the longevity of your drip irrigation system. Water quality can change from season to season, or even in-season with increased well draw-down which may lead to changes in mineral content of the water source. Conditions such as high salts, iron or manganese can cause the need for in season maintenance or water treatment.

Precautions:
Special considerations for hard water (high calcium or magnesium salts) when using fertilizer through subsurface drip irrigation:

  • pH – Alkaline water conditions can create an environment that is more favorable for phosphorus to precipitate. Lowering the pH to less than 6.5 is advisable. Pumping high pH water into SDI systems without acidifying it can result in problems including: scale formation and related blockage of emitters from calcium carbonate, iron oxides or manganese oxides
  • Bicarbonate – Excessive amounts of bicarbonate can produce a white chalky deposit which can restrict or plug drip irrigation emitters or nozzles. This is caused by calcium or magnesium carbonates and is the most common cause of chemical clogging in drip irrigation systems. Adding acid can reduce the amount of bicarbonate build up in irrigation water. See recommendations from drip irrigation equipment provider for management. 
  • Timing – When applying fertilizer through the irrigation system, the fertilizer solution should be moved through the irrigation system quickly, but uniformly. Allow sufficient time for flushing with clear water before the irrigation cycle ends.
  • Combining fertilizers – Never combine fertilizers, especially calcium and phosphorus before running through SDI. Calcium and phosphorus can form calcium phosphate which is capable of plugging the system. 
  • Solubility – Many water soluble phosphate fertilizers can have precipitation problems when injected at high application rates into hard irrigation water. They include: monoammonium phosphate (12-61-0), diammonium phosphate (21-53-0), monobasic potassium phosphate (0-52-34), phosphoric acid, urea phosphate, liquid ammonium polyphosphate (10-34-0) and long-chain linear polyphosphates.



Bio-K®

Growers who choose NACHURS have the opportunity to use a new and unique potassium source called Bio-K®, which is a combination of an inorganic salt reacted with an organic acid to form a potassium acetate fertilizer.  What makes Bio-K® unique is in the origination of its organic-based carrier (anion), the acetate molecule.  Acetate is a natural plant metabolite that has many important functions within the plant (auxins, sterols, amino acids, flavonoids, phenolic acids, etc.) as well as in the promotion of symbiotic relationships between plant roots and soil microbes/mycorrhizal fungi.  Bio-K® helps build rather than degrade soil structure/chemistry and is not corrosive to irrigation equipment.  Bio-K® is more rapidly and readily taken up by plants, which in turn leads to increased potassium use efficiency and higher productivity.
