• What is a dry matter measurement?
• What is a dry matter percentage?
• The dry matter content formula

Dry matter measurement measures the percentage of dry matter in a particular product. A dry matter meter removes moisture from the product by means of heat. The meter calculates the percentage of dry matter in the product before and after the measurement. With a dry matter measurement, the dry matter meter removes the moisture from the product through heat. The moment there is no more moisture in the product, the meter shows the dry matter percentage and how long the measurement lasted.  

The dry matter content indicates how much dry matter is present in a product. A product with a high liquid content will have a low dry matter percentage. If the percentage of moisture is higher in a healthy plant or fruit, then the plant is a lot more resilient. If you compare two plants, where one plant has had an additional product (such as bio stimulants) and it has a higher dry matter, this is likely to be positive. The elements that remain in the dry matter are the elements you look at with a dry matter measurement.  

Dry matter content expresses itself in percent by mass, or mass of dry matter divided by the total mass of the substance. 

The formula for dry matter content is Mges = mw + mt. 

• Mges = the total amount of material;
• mw = the amount of water;
• mt = dry matter content.

Using the dry matter content from a dry matter measurement, in which contents are found in the plants you make an assessment about food, biofuels and agricultural crops.

A crop check gives you an insight into the elements/minerals that have been absorbed by a plant. This insight makes it easier to detect a shortage. This way you can intervene in time and prevent problems. The result of a crop check can look like the table below. Before you start with a crop check you must first take a dry matter measurement. See below for an example of a crop check.

Establish a nutrional feeding schedule
For optimal crop results, it is important to use a feeding schedule that is tailored to the needs of the crop. A basic schedule is available for each crop type. From this basis, our crop care specialists can, if necessary, calculate with you an adapted feeding schedule that meets your specific needs.

Why is fertilizing with nitrogen important?
In greenhouse horticulture, nitrogen is often talked about as an element the plant needs, in addition to other main and trace elements. But what exactly does nitrogen do? Why is nitrogen important? And in what forms can you apply nitrogen to plants? In this article, our specialists explain.

Increase the CO2 concentration in the greenhouse
Along with water, CO2 is the nutrient element a plant needs most. The additional dosing of CO2 in the greenhouse is then the only option. You can do this in several ways. In this article, our specialist lists the possibilities.
