Seaweed/Kelp meal is a natural fertilizer made from dried and powdered seaweed. It is abundant in a wide range of vital nutrients, including as potassium, phosphorus, nitrogen, and many different trace minerals. Seaweed meal is known for its capacity to massively increase soil health and fertility by supplying abundant minerals and stimulating the growth of beneficial microbes and fungi.

Kelp meal provides over 80 minerals, nutrients and natural growth hormones for your soil. This is 100% pure seaweed meal.

The organic matter and soil conditioning properties in Kelp Meal are important to the fertility and productivity of agricultural soils. Its association with soil microflora, bacteria, and fungi play an important role in soil fertility and plant nutrient uptake.  The minerals released and humus colloids formed during the decomposition of Kelp Meal, result in the aggregation of soil particles and the retention of nutrients that might otherwise be leached from the soil. 

Use 1/2 cup per 30L of soil or 1 cup per square meter
