Micrel K 0-0-25
Growth Products’ 0-0-25 Liquid Potassium Solution is a crystal clear concentrate solution containing a very safe and reliable source of potassium from potassium carbonate. It has an extremely low phytotoxicity level, does not contain chlorides, and has the lowest salt index of any potassium source. 0-0-25 will adjust both water and soil pH levels. Since its clear solution does not settle out, 0-0-25 can be directly siphoned from the original container with a high ratio proportioner.0-0-25 is alkaline (pH =11), and will raise the pH levels of your stock tank and growing media.
A large majority of nutritional problems happen in greenhouse crops when the pH of the growing media is outside the optimum range for a particular species.
For instance, low pH levels will cause excessive availability of iron and manganese, which in turn leads to toxicity for plants. Conversely, high pH levels translate into deficiencies of P, Fe, Mn, B, Cu, and Zn. In either case, plants are adversely affected with visible problems like stunted growth and poor appearance.
Of course, different species of plants have different nutritional requirements. Generally, greenhouse ornamentals may be divided into three groups based upon their efficiency at micronutrient uptake:
One way to address the drop in pH that occurs with the geranium group is the use of 0-0-25. This liquid potassium solution is excellent for raising pH levels rapidly. 0-0-25 has an extremely low level of phytotoxicity, no salts, and no chlorides. Repeat applications may be necessary to maintain optimum pH once it is reached.
