Does seaweed raise pH?

Kelp and other seaweeds are ecosystem engineers that shape their physical and chemical surroundings. They soak up CO2 during the day through photosynthesis and thereby temporarily increase the pH level of seawater.

What is the NPK of liquid seaweed?

Kelp Meal Nutrients
Its NPK ratio is 1-0-4 and is more immediately released. Kelp meal nutrients can also be found in liquid kelp, which a cold processed liquid with higher levels of growth hormones, but again its NPK is negligible. Liquid kelp is useful for combating plant stress.

What is considered high nitrogen fertilizer?

Some of these fertilizers also contain phosphorus and potassium.

Can I put seaweed straight on the garden?
