Avocados tell you very quickly when they see a salts problem.
The first picture below shows salt burned leaves, whereas the second picture shows that Injecting Worm Gold Solutions into the root zone produced new leaves with no burning in less than 30 days.
The next set of pictures below shows avocados the farmer was told were dead due to high salts soil and high salts water. Injecting Worm Gold Solution gave a very quick response of fresh new growth. The second photo was taken 3 weeks after the first injection.
