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]
Nitrogen fertilizer can be converted by soil bacteria to nitrous oxide, a greenhouse gas. [129] Nitrous oxide emissions by humans, most of which are from fertilizer, between 2007 and 2016 have been estimated at 7 million tonnes per year, [130] which is incompatible with limiting global warming to below 2 °C.

Fertilizers with additional macronutrients (S, Ca, Mg) may add more numbers to the N-P-K ratio to indicate the amount. The additional numbers are similarly reported in the oxide mass fraction form. For example, a Polish fertilizer labeled "NPK (Ca,S) 4-12-12 (14-29)" has an equivalent of 14% soluble calcium oxide and 29% total sulfur trioxide. [6]

Cover crops are also grown to enrich soil as a green manure through nitrogen fixation from the atmosphere; [33] as well as phosphorus (through nutrient mobilization) [34] content of soils. Fertilizer trees aid organic farming by bringing nutrients from the depths of the soil, and by assisting in the regulation of water usage. [35]
