So for the last year and a half I've been studying to gain might be BCMA. I've read a lot of books on fertilization and typical PHC stuff. The more I read about fertilization the more I see how other companies might be miss using it. It really seems like it can be a two edged sword. So many companies with PHC programs try to sell fertilization for every single tree, and from what I have studyed, it seems very few trees actually need fertilization. Many articles and books pointed to the fact that mildly stressed tree sometimes are even more disease and pest resistant due to increased secondary metabolites, sap flow or cuticle thicknesses. Also where I live storm damage is always a concern due to High winds, from what I've read, constantly fertilizing increases growth rate, but the quick growth generally is weaker then slower growth which can increase possibility of storm damage later in the future. One company I know fertilizes every tree on a property, and I know some of the trees had scale and he told the customer fertilization will help keep the tree healthy and ward off the scale. I think few people know that many insects benefit from higher nitrogen content in trees. I read a book on Scale insects, and trees with higher nitrogen content increased there reproduction cycle, extended their life expectancy, and hardened and their shells which could make it more difficult for other predators to attack them. I believe there's definitely a reason to fertilize certain trees but only after a proper soil and foliage analysis has been done. It makes sense to the Home owner to fertilize every tree, just like you do a garden, you fertilize it to get better crops. I think it's a really easy sell to people who are wanting it, but many times it sold for the wrong reasons. What are your guys thoughts? Am I way off base?
