using the rapitest soil test kit?
so um where to begin. a few weeks ago I noticed some of my tomato plants becoming very ill and I started to wonder what could be going on.
at first I thought perhaps that I had bought bad plants ( which is possible if the seeds are of poor quality) . however, I started to observe the conditions to which my tomato plants were taking. as time passed on I noticed the the leaves kept yellowing and repeating the same conditions. so I pruned them and apply ed an pesticide to all of my plants. the reason for this is because I had some white flys/green flys. so I figured that could be the cause of it but that didnt stop the problem or anything. infact after the insects were dead the plants them selves kept showing the same signs. so I thought " hmmmmmm, must be a fungus or diseases. so I sprayed some fungicide on the plants thinking it would help but it didnt as well. so then I said " well I havnt planted in this soil for 3-4 years. let me check out whats going on". so I ordered a lust leaf rapitest kit and followed the instructions on the package to get an idea of whats going on.so wheres what I had gotten from it, im not sure how accurate they are or not but here goes.
the ph in my soil is roughly 6.8 ( I took 3 tests from the area where the affected tomato plants are)
Nitrogen is depleted or deficient in all 3 tests.
phosphorus is heavy in the soil supposedly. it shows in all three tests that there is a surplus of it or an sufficient amount.
potassium however is deficient or adequate
now whats bothering me about this all is the fact that im not sure how trusting these tests are but all of them are showing the same results. so im assuming that the test them selves are working correctly? can I count on them for a general idea on whats wrong? also, if they are right.... how do I lower the phosphorus levels in my soil and increase the other nutrients needed for my plants? I had read that phosphorus can use the levels to seem as if they are burning and yellowing because of the high amounts but im not sure if thats true or not in my case.
anyways, I need help regarding my issue or at least figuring out whats going on related to the soil and to the plants them selves. so if anyone could help me with this ti would be great. one other thing, I havnt seen any earth worms in my garden as well, im wondering if the soil conditions are in poor shape that not even those little critters wanted to come live in there.
one last thing I want to mention. the root system on the tomato's doesn't seem like its fully developed as it had years ago when I was gardening. I just started again after 3-4 years.
