Why can't A & B fertiliser be mixed together without water?

A & B fertilisers are designed to be used as a two-part system, with the A and B components being mixed together in a specific ratio to provide the plant with a balanced supply of essential nutrients. However, it is generally not recommended to mix A and B fertilisers together without water because the two components may react with each other and form insoluble precipitates or salts, which can be difficult for the plant to absorb.

When A and B fertilisers are mixed together, the combination of different salts and minerals can create an environment where the nutrients become less available to the plant, leading to reduced nutrient uptake and potential nutrient deficiencies. Additionally, some of the micronutrients in the B component may react with the macronutrients in the A component, which can further decrease the availability of the nutrients.

Therefore, it's important to mix A and B fertilisers together with water to ensure that the nutrients are properly dissolved and evenly distributed throughout the solution. This will help to ensure that the plant is able to absorb the nutrients it needs for healthy growth and development. It's also important to follow the manufacturer's instructions for mixing and application rates to avoid overfertilisation, which can damage the plant or lead to environmental problems.
