You can choose between different mulch films with dialed in lifespans. There are many biodegradable mulch films on the market. Only a few are certified compostable-biodegradable. With FilmOrganic, you can select the mulch film that has the desired lifespan, measured in months. For a short length crop, like lettuce or Summer squash, you can choose a mulch film with a 2 or 3 month lifespan. If you grow over-Winter strawberries, you can choose a mulch film with a 12 to 18 month lifespan.

No, we don’t. We only make certified compostable-biodegradable mulch films. These have proven to be more economical when considering the total cost-of-use. And they let you improve your productivity rather than pay to get rid of plastic.

Biodegradable means that microorganisms commonly found in the environment will transform a material into compost, over time. How much time? Your guess is as good as mine. Even oil is biodegradable if you wait long enough.

Compostable refers to ASTM D-6400, European standard EN13432, or the Japanese or ISO equivalent standard. It is a pass or fail test. To pass the test, the material must biodegrade like cellulose, when subjected to a temperature of 140F. The material must fragment into pieces smaller than 1/16th inch after 3 months. After 6 months, it has to be converted into CO2. A machine called a respirometer is used to measure the conversion rate into CO2.

ASTM D6400 is a pass-fail test. Either you meet the 90-day fragmentation requirement or your don’t. Either you meet the 180-day CO2 conversion requirement or your don’t.

Soil biodegradable is also an ASTM test. But it is not a pass-fail test. You merely report back the % biodegradable. It is essentially the same test as ASTM D6400, but the temperature is 80F instead of 160F.

Seedling certified means that the germination rate of future crops is unaffected. In other words, seedlings grown in a 1:1 mixture of soil : FilmOrganic compost grow just as well as seedlings grown in soil.

Certified means an independent 3rd party, like TÜV, the Austrian organization, has tested the material and stands behind the certification. Why is FilmOrganic compostable-biodegradable instead of soil- biodegradable?

Soil-biodegradable means the film will break down too fast. Think of this. To be soil-biodegradable, the film has to fragment into pieces smaller than 1/16th of an inch after 90 days. That is much too fast. The portion of the film anchored in the soil will be totally gone after 3 months. So even after 1 month, with a strong wind, the edges will start lifting up and the film will blow away. That’s a disaster waiting to happen...

The soil-biodegradable test sounds good. It’s got a catchy title. But it is not well adapted to North American growing techniques.

The composting test requires a slower break-down time. That is why it is a better suited test for North American growers. Growers need a biodegradable film with a lifespan. It has to last for a few months, then be gone within a few months after disking.

FilmOrganic is there when you need it, gone when you want it.

Yes. Keep the press wheels straight and 1’’ away from the bed. Apply a bit of tension lengthwise so the roll doesn’t free ride. Make sure your bed is nice and full. If you’re working in clumpy ground, check the trench opener. Soil can stick to metal surfaces and accumulate. The bottom roller needs to turn freely when you drive.

FilmOrganic is adapted to all the common types of mulch layers. Be careful with the Mechanical model 90. It lays the color inside out. If the film is white on the outside and black on the inside, it will lay the white side in and the black side up. All other mulch layers that are commonly found on the market do not have this issue.
