When I started this grow I sent samples or both my soil and of the tea that I would be using on the plants to the state Dept of Agriculture for testing. The first results showed that the soil was at a ph of 6.8 with N=3.0, P=1.3, K=1.44 and the tea was N=3.2, P=1.1, K=1.5 with PH at 6.77.
Today I got back the results that I sent them a couple of weeks ago. Soil was; Ph=6.83 with N=3.0, P=1.1, K=1.55, salts(I asked for testing)=.007/cubic yard(which they state was average for soil watered with ground water/well). Tea was N=3.0, P=1.22, K=1.7.
The reason I am posting this is that I have been wondering if I should do a flush due to salt buildup. This test sort of relieved the worries I was having because in the past I have had the plants go into shock after flushing and one of the things I wanted to eliminate was that shock and told them that when I sent in the samples for testing. Who ever did the test states on the comment section that "Your use of red worms in the soil and their castings have helped in maintaining a rich soil with balanced nutrient load, oxygen suppliment, microbe enrichment. Any salts build up have been decreased by normal watering with good draining in association with the interaction of the red worms maintaining a loose soil without compaction. Your nutrient suppliment is within the
guidelines set by the U.S. Dept. of Agriculture for use of food plants and comply with the guide lines for labeling as "Organicly Grown"." There ya go! Uncle Sam loves me!!!!
My planting soil is as follows;
40% FF Ocean Forest
50% my own compost (made of fall leaves, mostly oak, maple, birch with a small part of cypress leaves. I use cypress to get a tannic, or high Nitrogen mix, Grass clippings(I do not use fertilizers and stuff on my yard!) food waste, and dryed hydrilla( I get the hydrilla from the lake and dry it on the grass before putting it in the compost.
5% Vermiculite
5% Perllite
to this I add a handful of red wiggler worms in a 4-5 gallon bucket. Have to toss in some banana peel and coffee and tea grounds every couple of weeks to keep the worms happy.
My tea is as follows;
in a 5 gallon bucket I put approximately 1/4 of the bucket of my compost. a handful of worm castings and fill the rest with water. I use a bubbler from a 100 gallon fish tank with a aquarium pump and let it roll over night. When good and dark I ladle off the top half of the tea and use that.
I usually get approximately 1.5 gallons of tea which I use for 3 waterings, using the tea every other watering.
I have also added FF Big Bloom every once in a while when I see that the plants need a boost(leaves curling). My Mom in law added Liptons Tea to Mini's and Ozzies watering and had some surprising results.
