Earth Overshoot Day: Three tips on how the horticultural sector can move the date

Did you know our sector can make a significant change in the world? International Earth Overshoot Day marks the date when our demand for ecological resources and services exceeds what the Earth can regenerate in that year. This year’s Earth Overshoot Day lands on August 22. The remainder of the year corresponds to a global overshoot. In the Netherlands, Earth Overshoot Day even took place already on the 3rd of May. We do not have a second planet, nor a third, so at Grodan we believe it is time to #movethedate!

Half of the Earth’s biocapacity is used to feed us. One of the major global issues now is resource inefficiency in food production. That is where horticulture can step in and play an exemplary role. How will we move the date with our sector? Let’s have a look at three initiatives in horticulture that have its impact:

 

  1. Recycle your resources
    One solution to save organic resources, is by reusing them. Marc van Buijtene, Area Manager at Renewi in the Netherlands:

There’ll soon be a huge shortage of raw materials. Oils and minerals are running out; our planet is not inexhaustible. And, of course, most residual products were once raw materials themselves. So, we simply turn them back into raw materials.” Marc explains how it works in our Food Forward about circular horticulture.

  1. Switch to geothermal energy
    We’re aware that we can’t continually deplete the Earth’s resources”, says Kees Vahl, a cucumber grower. Together with his brother he has heated their greenhouses with renewable geothermal energy since 2012. “If it’s too big an investment at present, then my advice to other growers is to start off with other energy-saving measures. Many growers are involved in ‘New Cultivation’, testing things like double screens, lower temperatures and LED lighting.

  1. Minimize water usage with stone wool growing media
    Piet van Adrichem from Pijnacker discovered a way to drastically reduce water usage in cultivation. In 1969, he found that stone wool could help to save water, thanks to precise drip irrigation. And that’s how Grodan was born.

"If you plant a cucumber in soil, the plant has to use energy to obtain water and nutrition. But on stone wool, the cucumber needs a lot less energy. The plant will then put the stored energy into its fruit.”

Pay close attention to irrigation, nutrient content and cold feet

The sharp rise in energy prices is forcing many growers to reduce their lighting, to turn down the thermostat a little and provide screening for longer. If irrigation and nutrient levels are not adjusted accordingly, this can have major consequences for the crop and the roots, warns cultivation advisor Jos Beerens from Grodan.

Innovations in horticulture to look out for in 2022 and beyond part 2

Part II: Pyrgeometers and glass film technologies: innovations to support the transition to green energy in the greenhouse For the past years, two main challenges have been top of mind for greenhouse operators: labor (shortages and increasing costs) and the ever increasing costs of energy. Andrew Lee, Global Technical Knowledge Manager at Grodan and veteran in the horticultural business, sees these challenges not as limitations, but as important drivers for technological innovation in the sector. In the first part of this series, Lee dives into the latest tech solutions for challenge #2: the transition towards green energy in the greenhouse.
