Just a thought.......
In reviewing NPK a simplified overview would be that:
Nitrogen provides growing power and makes plant leaves and stems green.
Phosphorus stimulates budding and blooming.
Potassium (or K) promotes strong vigorous roots and resistance to disease.
We have discussed "spring sickness" and foliage problems. If we are
experiencing problems we should have a soil test completed. The University
and County Agriculture tests are very detailed and based on averages from
samples from various parts of the garden. I use the kits sold for the
person who wants to do their own testing as a backup to the professionally
done tests. This allows for testing individual sections of the property.
It seems to follow that if our K or potassium was low we could have disease
problems. I used to put my plants to bed for the winter with a mild 0-5-6
fertilizer. It has become difficult to find a reasonably priced fertilizer
with 0 nitrogen. Experienced gardeners taught me that a 1/2 inch of wood
ashes would provide an adequate amount of K in a garden that was low in
potassium. Now my hunt is for some product that provides the phosphorus.
Note, that phosphorus is an element you do not want too much of in the soil,
so do your testing.
Back to the books/Webb. I am trying to learn more about Tricontanol.
Take care,
Jack
