Chlorine is not just for the pool

This entry is part 1 of 12 in the series 13 Key Nutrients For Plants

Chlorine is present in our environment today often at levels considered a contaminant. However, it is essential for plant to open and close its stomates, or pores, and for electrical activity within cells. It is quite important to setting fruit and overall plant growth.

Deficiency can be suspected if you see yellow leaves that subsequently die and fall off, accompnied by a complete lack of fruit set and overall stunted growth. It is supplied naturally by the atmosphere, which moves it from the oceans to water around the world as rain and snow. Because the concentration of chlorine in the rain and snow is variable there is a remote possibility to have a deficient soil.

To correct a deficiency
  • add Bromine to the soil, which can support plant use of Chlorine

Chlorine can build up in the soil like any salt. Too much can show as burned leaf margins and tips, bronzed leaves that turn yellow and fall off.

To offset an excess
  • by leaching with salt free water
  • increasing the sand content of soil to facilitate the movement of water
  • planting plants that use high amounts of chlorine, such as tomatoes

Soil testing is an important activity for a successful garden. Soil stewardship is an ongoing process, where you test and amend, grow some stuff, then test, amend and grow some stuff….and so on. Focus on building soil tilth so it can really hold and make available to the plants all the important nutrients. You do this in part by adding compost, manure, rock dust, bone meal, kelp & fish emulsions. Read this article series to learn more about each of the 13 key nutrients for your garden.
