FieldKelp
Liquid Kelp Extract for US Growers
100% Natural.
Available in most US States.
Your crops face real pressure.
FieldKelp is built for that.
Rising input costs, tighter margins, and increasingly unpredictable weather make every acre harder to manage.
Drought stress, salinity, and temperature extremes hit yields when you can least afford it. And adding a new product to your program only makes sense if it delivers a clear return.
FieldKelp is a liquid kelp extract designed to work within your existing fertility and crop protection program.
Applied at low rates, it is designed to improve how efficiently your crops use the inputs you're already putting down, strengthening their ability to handle stress, and FieldKelp has been shown in independent trials to increase yields across a range of crops.
What is FieldKelp?
FieldKelp is a 100% natural liquid kelp extract derived from cultivated Saccharina latissima and/or Macrocystis tenuifolia — two species of kelp grown on marine farms off the West Coast of Canada and Alaska.
The kelp is harvested at peak nutritional value and processed at Cascadia Seaweed's advanced processing facility, which preserves key bioactive compounds.
FieldKelp can be applied by foliar spray, transplant root dip, tuber dip or soil drench and is designed to aid plant growth and crop yields.
Available in select US States.
