The primary nutrients plants need are nitrogen (N), phosphorous (P), and potassium (K)— that’s the N-P-K you see on most fertilizer bags (Here's how to understand fertilizer numbers and letters).
So, if you’re in doubt about fertilizing, it may be best to avoid using any fertilizer in winter unless your plants look like they’re struggling. You can start fertilizing again when your ...

Nitrogen and potassium are also needed in substantial amounts. For this reason these three elements are always identified on a commercial fertilizer analysis. For example, a 10-10-15 fertilizer has 10 percent nitrogen, 10 percent available phosphorus (P 2 O 5) and 15 percent water-soluble potassium (K 2 O). Sulfur is the fourth element that may ...
Fertilizer trees are used in agroforestry to improve the condition of soils used for farming. As woody legumes, they capture nitrogen from the air and put it in the soil through their roots and falling leaves. [1] They can also bring nutrients from deep in the soil up to the surface for crops with roots that cannot reach that depth. [2]
