There is no difference in uptake from these forms. Both require irrigation or rainfall to distribute nutrients in the soil water solution so they are available for uptake. Learn to read the fertilizer analysis. Use soluble fertilizers for a quick response. Use slow-release fertilizers for regular maintenance.
Many organic materials provide excellent sources of nutrients.
Composted sewage sludge, poultry manure, cow manure, composted leaves and other vegetation, peat moss, sea weed, and fish emulsion are all organic sources of nutrients. The problem with using organic materials as sources of nutrients is that the content of available nitrogen and other nutrients is often unknown. The level of nutrients in unprocessed organic materials, bulk sources, or organic material produced at home is anyone's guess. You may not apply enough fertilizer to get the desired result, or you may over-fertilize, causing nitrate leaching, salt toxicities, or excessive vegetative growth to occur. Organic materials can be excellent sources of nutrients.
