Sulfur Uptake and Transport According to its Status Either Organic or Inorganic Form

The objective of this study was to investigate the effects of different sources of sulfur fertilizer either organic as plant residue (composite tea), animal residue (chicken manure) or inorganic fertilizer (potassium sulfate) or industrial waste water on the ionic contents of potassium , sodium , calcium , magnesium, and iron in roots and shoots of broccoli plants (Brassica oleracea L. var. italic). As well as sulfur interactions: sulfur content, sulfur requirement, sulfur uptake, rate of transport sulfur from root to shoot and distribution of sulfur in broccoli plants. The obtained results showed that the potassium, sodium, calcium, magnesium, and iron contents in growing plants in different types of soil is closely linked to the stage of plant growth as well as the plant organ and the type of soil used and also on the type and concentration of various fertilizers. The sulfur interactions included changes: in the total sulfur content, sulfur requirements, sulfur uptake and rate of sulfur transport from root to shoot. As well as, the change in the distribution of the sulfur in different plant organs: roots and shoots. Above parameters relied mainly on the soil type and various treatments.
