It is important to take measurements in the crop, in order to see whether the product that was used has had any effect. This is also interesting because in 20% of the Dutch greenhouses, there is too little silicon available to the plant.
When executing a measurement, the concentration of absorbable silicon will not be the same everywhere. Not even when exactly the same amount is administered. This depends entirely on the growing medium (which type of soil or substrate), the pH value,
temperature and humidity of the soil.
The non-absorbable silicon forms that occur in the soil are easy to measure in the drain water. What should be kept in mind is, that this is where the non-absorbable silicon is measured. The silicon that is of no use to the plant.
The effect and presence of silicon can also be measured in another way. The possible effects become visible
by analyzing an untreated and a crop treated with Silicapower in a similar climate, at the same time.
When using SilicaPower, the effect and presence of silicon can also easily be measured in a different way. By doing a dry matter measurement before using SilicaPower and after using SilicaPower, you can see how much absorbable silicon is actually actively
built into the plant. Like this, the effect of the silicon on the crop can be assessed for each situation. On average, the concentration of silicon in the crop is between 0.1% and 10% of dry matter. Because this varies per crop, it is best to take a measurement
in order to gain insight into what kind of crop the effect is.
