Bio fertilizer

Hello fellow gardening enthsiasts!

We, as students of the Fontys University of Applied Sciences in Venlo, the Netherlands are highly interested in your opinion regarding the future of fertilizer.


The survey we have prepared will help us conduct research on this topic and will not be shared with external sources.


Our group would be very thankful for each reply we can get. Thanks for your time and for helping us making the world a more sustainable place!

    I use Liquid (Tomorite and Seaweed Extract), Powder (phostrogen) and Granular (Miracle Gro)
    I can only select one of these options on your survey

    I think you seriously need to look at the options you're giving. It's illegal to grow cannabis here, so it would be better to remove anything referring to that.
    I also agree re the point about only being able to select one choice in questions. Very few people will only use one type of fertiliser, regardless of what they grow.

    Survey no good for me.
    ’do you use fertiliser’
    next question,  ‘which one’ 
    So can’t submit that.

  • Maybe start with a survey on how to design a survey?

    I think there is a translation problem. They probably mean wild flowers, not weed/cannabis.

    I've never heard of any of those fertilisers.

    I sometimes use Bio-Bizz Fish Mix liquid fertiliser. That’s actually an excellent Dutch product, but not on the list.

    The problem with simple tick-box surveys like these is that it’s difficult to select a response in any accurate or meaningful way. Most people use from nothing at all to a whole variety of different products, possibly a mix of both artificial and ‘bio’, at different times of the year and at different frequencies for different plants and purposes, depending on their specific soil and growing conditions.

    It would have been helpful to define ‘bio’ too. In my book that means any natural/organic fertilisers derived from rocks, animals and plants rather than an artificial chemical fertiliser synthesised in a lab. So that would encompass alfalfa pellets, homemade compost, leaf mould, animal manures, seaweed extract, rock minerals, sand, grit, pumice, FBB, comercial compost, peat, woody mulches etc.

    The environmental impact of something labelled ‘bio’ is not necessarily low, quite the opposite in some cases. I could slather my beds in peat and smugly tick the bio box!

    I have filled in the survey, but it is by no means the full story. The survey doesn't allow you to pick different answers for different kinds of fertiliser for different kinds of plants at different times, for example I might expect to see the effect of a liquid feed on my pot-grown tomatoes in summer in a shorter timescale than for bone meal used when planting a bare-root shrub in the winter.
    I guess it's legal to grow your own cannabis in the Netherlands.
