Worldwide in soils rich in nitrogen, especially on wasteland: Leaves and young shoots; edible raw or prepared as a green vegetable [39] Good-King-Henry: Chenopodium bonus-henricus: Most of Europe, West Asia and eastern North America: Young shoots (until early summer) and leaves (until August). The shoots can be cooked like asparagus, and the ...
For example, nitrogen compounds comprise 40% to 50% of the dry matter of protoplasm, and it is a constituent of amino acids, the building blocks of proteins. [9] It is also an essential constituent of chlorophyll. [10] In many agricultural settings, nitrogen is the limiting nutrient for rapid growth.
Nitrogen is therefore a necessary ingredient in the production of proteins. Hence, legumes are among the best sources of plant protein. [citation needed] When a legume plant dies in the field, for example following the harvest, all of its remaining nitrogen, incorporated into amino acids inside the remaining plant parts, is released back into ...

Plants that contribute to nitrogen fixation include the legume family – Fabaceae – with taxa such as clover, soybeans, alfalfa, lupins, peanuts, and rooibos.They contain symbiotic bacteria called Rhizobia within nodules in their root systems, producing nitrogen compounds that help the plant to grow and compete with other plants.
As with most legumes, snow peas host beneficial bacteria, rhizobia, in their root nodules, which fix nitrogen in the soil—this is called a mutualistic relationship—and are therefore a useful companion plant, especially useful to grow intercropped with green, leafy vegetables that benefit from high nitrogen content in their soil.
It is a rich source (20% or more of the Daily Value, DV) of vitamin A, vitamin C, manganese, and folate (31-52% DV), with an especially high content of vitamin K (403% DV) (table). Spinach is a moderate source (10–19% of DV) of the B vitamins , riboflavin and vitamin B 6 , vitamin E , potassium , iron , magnesium , and dietary fiber (table).
