Yo I got the agree strongly with Tremor about Organics use. Bridge products having both synthetic and organic nutrient work the best on almost all soils. I will not in any way discount the use of Humates, Humic acid, or fulvic acid. But I will try and stress the need for SOM (soil organic material). SOM both increase field capacity and drainage. In sandy soils it increases CEC. In all most all soils it increases microbes both beneficial and non beneficial. In Microbiology We say "Everything is everywhere, but the environment selects" Adding microbes to soil doesn't increase populations very long. Only if the environment is correct will microbe population increase. SOM helps the soil provide the right environment for increased microbe populations. In todays rising prices we need to look at the history of our science. Organic agriculture and horticulture has worked to some degree since man first farmed. We as applicators need to use the best of these methods. But Organic people must also realize this is the 21th century and synthetics add greatly to the organic.
