i asume you did a layer test first! that be were i would start,i have bulk yards near me and i buy the enriched compost from them,black as coal but sand silt and clay are all even across the board,from there you can build mountains hahah,but ya this test above first i seen like this,that magnese count is pretty high ,calcium and magnesium are to low in my opinion,but can also be feed right into the soil ,hell im probally wrong but how many acres you talking about,or hectare if over seas,i screwed up and got 3 yrds of a garden soil from same folks both same price,45 a yrd,did a layer test on the garden soil and even though it was OMRI certified the garden soil barley had organic matter at all in it,mainly peat and sawdust,might work for some folk but here ,you have 3 weeks of winter,1 month of fall which is all the leaves falling from the trees in mid summer and rest year summer,every day watering aint happening if you dig,also compact quick
