Results have to be checked for statistical significance with a p value of 0.05
The "bio"char results are expected to show improved growth.
So therefore; null hypothesis is there is no difference.
The difference has to be checked for each soil type first
eg; sandy and sandy bio
And then overall; bio, non bio
LSA and DM are to be measured independently.
I am assuming this will be less than an hours work for someone experienced.
Please contact me for any clarification. I am online now.
