I have been tried sugar beets 4-5 years ago but it was quite high input crop. It needs a lot of fertilizer and herbicides to grow. USA has solved second problem by sugar beet Roundup Ready hybrid varieties. Last year over 90% of sugar beet crop game from Roundup Ready varieties in USA. Sugar beet also needs constant field rotation and you can plant it on the same field every 4-5 th year.
Sockerbetor är kanske intressanta att odla på mark som har blivit för salt för andra växtor eftersom de tåll mycket mera salt. Då borde behovet av ogräsbekämpningsmedel också minska eftersom ogräset inte tåll saltet lika bra?

Although sugar beet is grown only in the temperate and Mediterranean regions the crop itself is also capable to stand heat and can yield well in tropical environments (Chatin et al 2004). It has a long tap root that penetrates the soil and is able to extract water and nutrients from considerable soil depth. Another characteristic of sugar beet is that it tolerates salinity to a greater extend that do other crops. This makes it possible to grow on saline soils. Response to climate change: In view of climate change, sugar beet is a very adaptable crop which can tolerate drought, saline soils and heat.
