. Tolerant plants can grow in desert land which is
to ae deflcJe-flt Zn most 0f the 0,j0n,nutrieflt.5.
Therefore, economical plants should be classified accord— ig to its tolerance to micronutrients.
The study should be specific to every raioronutrients as
plant could be tolerant to one elenient wbereas it is sensitive to another. Plants should be grouped and classified
a table which show the sensitive — the semi—tolerant and the t,lerant plants to defeciency of one rnioronutrients.
As some desert plants grow normally under defecient 1:onditions and sometimes with high calcium carbonate; the, ‘iuthor collect a large number of deserts and arid regions of ypt where the soils are sandy or sandy calooreous.
In the present study, 35 herbaceous and shrubby species ere included. These are representatives of 18 families. The .ist included the iniportant azedicn plants.
The chemical and physic’si cnrachteristics of the soil ere carried out to assess its propertieo of micronutrients nd correlate v.ith the plent content of these nutrienta. coording to this, the studies or desert plants were classified to three catogeries.
