A series of experiments was done to see the effects of various minerals on the quality of plant growth. More importantly, these experiments can show the effects of a soil that is lacking (deficient) in any essential mineral.| (expt.) MINERALS added to the soil | EFFECTS of the mineral on plant growth |
| (1) nitrate, phosphate, potassium, trace metals (Cu, Fe, Mg, Mn, Zn) | healthy roots, strong stem, healthy green leaves, well developed flowers |
| (2) nitrate, phosphate, trace metals (Cu, Fe, Mg, Mn, Zn) | healthy roots, strong stem, older green leaves yellow with black spots, poorly developed flowers |
| (3) nitrate, potassium, trace metals (Cu, Fe, Mg, Mn, Zn) | poorly developed roots, strong stem, leaves turn very dark green then purple, poor quality flower blooms |
| (4) nitrate, phosphate, potassium | healthy roots, strong stem, yellowish leaves, well developed flowers |
| (5) phosphate, potassium, trace metals (Cu, Fe, Mg, Mn, Zn) | healthy roots, thin weak stem, smaller yellow leaves, well developed flowers |
From the experiment data, which mineral deficiency causes poor root growth? [9d-27]
