One of the primary factors that controls plant growth is light; and in general, the more light the better. Better growth and higher yields are the result. Recent research has shown that white on black reflective mulch increases tomato yields over 30% when the mulch is laid between rows and when the tomatoes are planted at high density (compared to bare soil between rows). With the white reflective mulch, light levels in the plant canopy are three times higher than with bare soil. SRM White has dual properties: light reflectio and weed control since a layer of white is co-extruded over the black. Yet this embossed, high density mulch is only 0.7 mil thick. It is even tough enough to hold up under foot traffic during the harvest season.
In Northern states where the season is short, SRM-White is a vital link in improving yields by increasing the amount of light available to the plants. In more southerly states where a summer crop is planted, SRM-White deflects heat and keeps soils cooler.
Advantages of SRM-WHITE:
- A very durable film that is easy to lay and take up
- Good reflectivity throughout the whole season -- will not fade
- Photosynthesis increases with more reflected light
- Provides a very clean and pleasing environment between rows
- More than 30% increase in tomato yield
Product Description: White on black embossed 4' x 6000', 0.7 mil high density polyethylene, 86 lbs/roll.
Installation Tips for between-row use
- Keep rows the same distance apart.
- After laying in-row plastic mulch, flatten out the area between rows. Do this before the soil gets hard -- to reduce clods.
- Remove large stones, if possible.
- Roll out plastic taut between rows and pin down the sides every 6 to 8 feet.
- Keep the plastic as clean as possible to maintain maximum reflectivity.
Crops that are suited for SRM-White
- Tomatoes are very responsive to this mulch. Other crops that might do well would be pepper, egg plant, and cucurbits. More trials are needed with other crops.
