Solufeed Superior Vigil

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 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 dissolved in 10 litres of water) which is further diluted 1:100 giving a final dilution of 1 gram of Solufeed Superior Vigil 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 (at normal rate of use) were compared.

For Soft Water Areas

Soft water contains very low levels of calcium or magnesium ions. It may be necessary to add calcium (usually as calcium nitrate) to provide plants with the optimum level in the feed. However calcium is normally incompatible with other soluble fertiliser components, and so growers invest in separate tanks and diluters especially for calcium.

Solufeed Superior Vigil can be mixed with calcium nitrate in concentrated solution up to an equal basis. Ie. 1 kg of Solufeed Superior Vigil + 1 kg calcium nitrate in 10 litres of water, then further diluted 1:100.

This mix will provide 190 ppm of calcium in the final feed which is more than sufficient for most crops.
