What is the difference between Greensand or Seaweed fertilizer Seaweed helps to improve the structure and stability of the soil, as the organic components of seaweed meal break down, they provide nutrients for plants and increase the nitrogen content of the soil, it also provides B vitamins like B1 and B12, as well as E, K, and folic acid, which are taken up by plants grown in such enhanced soils. Trace elements, especially iron and calcium, exist in seaweed extract in their chelated forms, which plants can absorb more readily than from plain dirt. Adding seaweed extract increases the amount of chlorophyll in the leaves of plants. Seaweed also contains plant hormones that encourage the growth of foliage. Plants treated with seaweed extract are more resistant to pests like spider mites and aphids. The extract provides some resistance to diseases like scab, mildew, and fungus as well. Enriching the soil with the seaweed strengthens the native bacteria and fungi that provide some of this protection.
Greensand is made from glauconite and is commonly used to treat chlorosis in plants and lawns, percentages will typically range from 5-7 which is a good alternative to Ironite as it will not harm the water supply due to runoff.
Sea Weed is for foliar feeding or for use as a soil drench to give plants the missing nutrients the desperately need. If you have any other questions please let me know.
