Sorrel is a slender herbaceous perennial plant about 60 centimetres (24 in) high, with roots that run deep into the ground, as well as juicy stems and edible, arrow-shaped (sagittate) leaves. The leaves, when consumed raw, taste like a sour green apple candy.ommon sorrel or garden sorrel (Rumex acetosa), often simply called sorrel, is a perennial herb in the family Polygonaceae.
Of all the essential nutrients, nitrogen is required by plants in the largest quantity and is most frequently the limiting factor in crop productivity. 1  In plant tissue, the nitrogen content ranges from 1 and 6%.
In the same way, adding nutrients to water fertilizes water-dwelling plants. Typically, plants in water will continue to grow until something they need (sunlight, carbon dioxide, oxygen, or nutrients) runs out. In most streams and lakes, phosphorus or nitrogen limits plant growth.Adding more of the limiting nutrient, in fact, can stimulate too much plant growth, which starts a chain of events that may eventually deplete oxygen from the water and kill fish and other aquatic animals.n most streams and lakes, phosphorus or nitrogen limits plant growth.
