Because of the increasing risk of contamination of our material, by various diseases and pests, we have taken some strict hygiene measures. We take the delivery of healthy plant material very seriously. For this reason we have built a 15,000m² insect free glasshouse for the multiplication of SE-certified plants. The greenhouse has a glass deck, so the risk of infection by bacterial diseases (moisture condensation, irrigation) and root diseases are minimized.

We take producing healthy, high quality of plants very seriously. For this reason we have built an insect free glasshouse for the propagation of all our SE1 and SE2 plants in 2007. This glasshouse is equipped with a glass deck, which means less risk of infection by bacterial diseases and root diseases by less moisture condition and excessive rainfall. Plants are grown on a substrate soil, reducing the risk of infection from the soil to significantly low levels.
Soil balance analysis (SBA)
A soil balance analysis reveals the ratios of the various minerals and trace elements in our soil. These ratios tell us whether our soil is in balance. On the basis of an SBA, we can calculate the precise amounts of calcium, magnesium, potassium, etc. needed to restore our soil’s balance.

Soil structure
We think a good soil structure is one of the most essential part of good cultivation. Along with plant nutrients, a soil must have a continuous supply of both air and moisture. Soils with poor structure may become saturated from water logging during wet seasons, thus they lack the air gaps required for optimum root growth. To have more focus on the soil and its growing potential, we are convinced that we can produce stronger, healthier strawberry plants.

Crop rotation
We use Crop rotation as a method of organic pest-control which reduces the build-up of soil borne diseases. By rotating crops between sites the pests tend to decline in the period when their host plants are absent which helps reduce build-up of damaging populations of spores, eggs and pests.

To have more focus on the soil and it’s growing plants, we are convinced we produce stronger and more heathy strawberry plants.

Plant and Leaf Analysis
We use leaf analysis to monitor our plant nutrient levels. While our soil tests reveal the quantity of certain nutrients in the soil, leaf analysis shows us exactly what the plant has succeeded in taking up. To us, leaf analysis is helpful for detecting nutrient deficiencies before they can have a detrimental effect on plant health or yield.

To prevent infections by and dispersal of pest and diseases we have intensified a number of strict hygiene measures over the past few years.

Grading and storage
Grading and storage of the plants is the last but certainly not the least of these important processes, before delivery of the plants. All the different plant types are graded with great attention to detail in our various categories. After grading the plants are packed and stored in our well-developed cold stores.

We have got a number of modern and reliable cold stores for the cooling and storage of the plants. The cold stores are equipped with a fog system to prevent our fresh plants and fresh tips from dehydration. A precise temperature control system continuously measures the temperature in the cold store, as well as inside the boxes and gives us an alarm if it deviates too much.

We have developed modern buildings for a fast and accurate preparation of the strawberry plants. We also have a number of modern and reliable cold stors for the cooling and storage of the plants. The cold stores are equipped with a fog system to prevent the plants from dehydration. This is controlled by a precise temperature control system with alarm.
