? for Al T. Gritty Mix Preparation
Hello Al -
Happy Easter! Hope all is going well.
I believe I have all the components and am ready to try to make a batch. I would like to make sure I have the process correct.
1. I believe you make a gallon at a time - so you would mix 1/3 Gallon Grit, 1/3 gallon turface and 1/3 gallon pine bark fines.
2. To the above mix add: 1 tablespoon gypsum and 1/4 teaspoon epsom salt
3. Once the mix is prepared to step 2 then mix all ingredients with a small amount of water - just enough to moisten the mix and then I need to let it sit for a while before using correct?
?: I had thought due to the acidity of the bark I needed to add lime?
2nd ?: The gypsum and lime I have is fairly powdery. Should I look for larger sized material since the powdery size may cause problems with too much water retention?
Side ?: If one were to (hypothetically) consider the decrease in the genetic growing potential of a plant in a peat based material is it possible to estimate the percentage decrease coming from problems with the PWT and compaction of the soil medium? I am just curious if for example all other things being equal does the PWT decrease the genetic growing potential by 50% and the compaction of the soil by 50% or is either of the factors much more important than the other i.e. 90% decrease due to PWT problem and 10% due to hard,compacted soils?
I could imagine that both are very important - with significant PWT - you get root rot and plant dies but with hard soil roots can't move and seek out nutrients. But if nutrients are being supplied by chemical fertilizer maybe compacted soils is less important - Since with root pruning you could keep the growth of smaller feeder roots in an active phase - and since nutrients are being provided the roots don't have to move through the soil seeking nutrients out?
Thanks again in advance for your help.
