不对吧? 看这个:
http://www.amazon.com/Jobes-6005-18-Pack-Outdoor-Fertilizer/dp/
含量是 8-24-8
P要大于N/K的总和.

: 12-12-12比例对番茄不是最好,番茄的肥料需求是K>N>>P. 另外追求有机的可以上sul
: po mag(K)和bone meal(P)。

the first part is true... however how to use fertilizer to grow organically,
I beg to differ.

: All organic materials will have to be broken down into inorganic materials
: before they are used by plants. I may expand on this topic to dispel a lot

There are a lot of advantages to using organic fertilizers. Two of the most
obvious are improvement of soil texture and addition of essential minerals.
Good soil texture and micronutrients are every important to any plant.
Chemical fertilizers only provide those elements on the label. For example,
12-12-12 only has N, P and K, but nothing else. However, micronutrients are
needed by plants in very small amount and these elements are in the soils
already. Therefore, chemical fertilizers can achieve the same goal of higher
yield with much less fuss, if one can be a little patient by not applying
too much at a time.
I am only talking about vegetables like tomato, cucumbers and leafy
vegetables. it is a very case with some crops like watermelon. Watermelon
grown with organic fertilizers are sweeter.
