The growing season is in full swing. In June, many crops enter a critical growth phase: potatoes begin tuber initiation, fruit trees are setting fruit, and vegetables are growing at full speed.
If you started using biostimulants this spring, June can be an important moment to keep supporting your crops. Right now, in the middle of the season, plants demand extra care, and you can amplify the effects of earlier applications.
June may not be the starting point of your biostimulant strategy, but it is an important checkpoint. It’s a phase where the crop is running at full capacity, and timely support can make a visible difference in yield, quality, and resilience. And even if you’re only starting now, you can still help your crops build resilience against heat and drought.
Biostimulants are not quick “boosters,” but building blocks in a broader crop management strategy. That said, a well-timed application right before a stress period can provide targeted extra support. They gradually strengthen plant and soil resilience, nutrient uptake, and vitality.
A repeat application of biostimulants in June helps to:
• Maintain the effect built up earlier in spring.
• Support the crop during a stress-sensitive growth stage.
• Improve nutrient use efficiency from fertilization.
• Increase the likelihood of higher yields and better quality.
For most crops, June is not the ideal time to begin. Biostimulants work best before or at the start of the growing season, when the plant is still in active development and root systems are expanding.
Starting late can come with drawbacks:
• Most of the crop’s resilience-building phase has already gone by.
• Soil biology is no longer activated to its full potential.
• The impact on nutrient uptake is smaller, as root development and uptake capacity have already matured.
Without this foundation, the effect of biostimulants is limited. They are intended to prevent problems (preventive), not to fix them after they arise (curative).
Still, a targeted application in June can add value: you can actively strengthen crop resilience and help mitigate the impact of stress from heat or drought.
Important to note: if you’re working with crops that are only now being planted or sown, June can in fact be an optimal starting point. Examples include:
In these cases, an early application in June is highly effective. Would you like tailored advice on the right timing and application per crop? Feel free to contact us.
A June application is not a silver bullet on its own, but it is an essential part of a well-structured program. For products like Siliforce, repeating in June is a standard part of the schedule. For others, such as AMX or Micromix, the exact timing depends on the crop, growth stage, and application method.
When growers start on time and repeat at key moments throughout the season, the benefits can be very clear. For example:
Siliforce in pear orchards 🍐 (CAF trial fields 2023):
• +9% more pears
• +4.5% higher yield
• €1,300 extra margin/ha (based on 40 t/ha at €0.80/kg)
Siliforce in potatoes 🥔 (WUR trial fields 2023, variety Fontane):
• Higher share of 40+ and 50+ tuber sizes
• Better storability
• €1,200 extra margin/ha
• Every €1 invested in Siliforce returned an average of €6.50 in profit
These results are the outcome of a complete approach: starting early, repeating at the right time, and applying correctly.
Applied strategically, biostimulants can boost performance in several ways, for example:
• Higher yields per hectare: through improved tuber distribution or better fruit set
• Better quality: firmer produce with longer storability
• More efficient nutrient use: thanks to improved uptake and more active soil biology
• Greater crop security: as crops are better able to withstand stress
In some crops, biostimulants also reduce storage losses and contribute to more stable crop development, which is key for both yield security and market quality. The precise added value varies by crop, soil type, and season. Feel free to request a tailored return-on-investment assessment! We’ll be happy to think along with you.
Already working with biostimulants? June is the time to build on what you’ve started. Starting a new crop? Set yourself up for success with the right applications from day one. For established crops, pay close attention to stress periods and apply biostimulants where targeted support is needed.
Always pay attention to the correct mixing order, method of application, and weather conditions – especially during dry spells or when using tank mixes.
