Solufeed Superior Vigil v.2

An acidifying and balanced starter water soluble fertilizer which helps overcome the difficulties associated with high pH water with high bicarbonate levels. Buy Online

Superior water soluble NPK fertilizers ONLY available from Solufeed.  Suitable for hard and soft water.

Uses

Solufeed Superior Vigil v.2 fertilizer is used in the same way as other soluble fertilizers. The normal method is to make up a 10% stock solution (1 kg of Solufeed Superior Vigil v.2 dissolved in 10 litres of water) which is further diluted 1:100 giving a final dilution of 1 gram of Solufeed Superior Vigil v.2 per litre of irrigation water. Hard water usually contains high levels of calcium and/or magnesium ions together with bicarbonate (HCO3) ions; the pH is usually high.

For Hard Water Areas

The calcium in hard water is beneficial for growing plants but the associated alkalinity means that most plants do not respond well to fertilizer and can be prone to trace element deficiencies. Some commercial growers invest in equipment to treat hard water with concentrated mineral acids that will reduce the bicarbonates and reduce pH to improve growing performance.

Using acidic Solufeed Superior Vigil fertilizer will neutralize some of the bicarbonates in the water and will reduce pH thereby improving conditions for plant growth. This is demonstrated by the results of a trial conducted in North Yorkshire, UK. Here the pH and bicarbonate levels in raw water and the same water plus Solufeed Superior Vigil v.2 (at normal rate of use) were compared.

For Soft Water Areas

Soft water is unlikely to be alkaline and normally contains low levels of bicarbonates (HCO3). Do not use acidic Vigil v.2 or Fleury v.2 in water with bicarbonate levels of less than 150 ppm because the fertilizer may over-acidify the water.
