See the table at the bottom of this page for the interactions that excesses cause: cartage.org.lb/en/themes/Sciences/BotanicalSciences/… | |

| Jun 8, 2011 at 19:53 | comment | added | bstpierre | No problem. They all have to be in forms that the plants can use directly. For example, there's tons of nitrogen in the air, but it's useless to plants. They need specific nitrogen-containing compounds to be present in the soil. The chemistry gets complex fast... I only know enough to be dangerous :) | |

| Jun 8, 2011 at 19:41 | comment | added | bstpierre | "macro" = big, need larger amounts. "micro" = small, need smaller amounts? I've edited the quote to make it clearer that the "secondary" refers to macronutrients that are usually present in sufficient quantities. | |

clarify naming

| Jun 8, 2011 at 19:32 | comment | added | mfg | Just wondering: is there a reasoning behind the naming convention of macro-/secondary/micro-nutrient? | |
