Old Reviews Seaweed compost for the soil

[moutros]

Hello everyone, i started making my own soil and i found this very interesting compost
which according to directions should be used 50-50 with the soil

Specifications
Bulk density ~0.55 - 0.60 kg /lt
Moisture content 25% - 30% m/m
Dry matter 47%- 55% m/m
Organic matter 20%- 35% of the dry matter
Carbon:Nitrogen ratio 18- 25
pH 7 - 7.5
Electrical conductivity 0.50 - 2.50 mS/cm

Nutrients & Macrominerals

(N): 0.80 - 1%
(P2O5): 0.32 - 0.50%
(K2O): 0.90 - 1%
(CaO): 28 - 33%
(MgO): 2 - 3%
Copper (Cu) > 15 ppm
Manganese (Mn) > 450 ppm
Iron (Fe) > 3500 ppm
Zinc (Zn) > 70 ppm
Boron (B) > 650 ppm

Composition

• Sea plant (Posidonia oceanica)
  
  
• Grape skin
  
  
• Olive leaves & olivecore

Benefits of Biological compost Posidonia
A natural soil improver that offers the following benefits:

• Improved structure & texture
  
  
• Increased moisture retention
  
  
• Improved aeration
  
  
• Increased nutrient value
  
  
• Improved fertility in tired or un-worked soils
  
  
• Loosens clay soils
  
  
• Stimulates healthy root development

So all that sounds really good except for the ph which is a bit on the high side,

So i used some cheap soil, added the same amount of this compost , some perlite for aeration and a little bit of composted chicken manure

So what do you guys think? Is there anything missing? and what do you think about the compost?

I know nothing about soil composition, so can't help there - but 7-7.5 PH seems a bit high for our purposes. Perhaps with some lime mixed in it could be lowered?

the ph of the soil 7.0-7.5 is to high for mj , it dont think it will help your plants in that alkaline range , around 6.0 be ideal range if you can alter it in some way.
one option, could get some sodium alginate & dissolve in water an ph to a ideal range and then infuze the soil with it , instead of buying seaweed fertiliser with other waste components added to bulk it up.
