Draft Experimental Design
Sensitivity of Southern Magnolias to Soil Salinity
The research paper tests the sensitivity and tolerance of Southern Magnolias to high
soil salinity and how soil salinity affects the growth and health of Southern Magnolias. The
research hypothesis is that Southern Magnolias, including salt sprays, are sensitive to high
salt content in the soil and air. The Southern magnolia tree grows best in moist, well-drained,
and acid soils and is adaptable to various soils, including clay, loam, and sandy soils (Miley,
2013). Despite high moisture tolerance, Southern Magnolia does poorly in wet or poorly
drained soils. The experimental design will test the tolerance and sensitivity of southern
magnolia in soils with high salt levels. In most cases, southern magnolia is affected and are
more sensitive to salt in the air than salt in the soil. The experimental design will take place
over two weeks and in an area adjacent to a beachfront to determine the tolerance and
sensitivity of southern magnolia to salt salinity. Soil salinity is a soil condition where soluble
salts impede the plant's growth and lead to stunted growth (Velez, 2023). High salt levels in
the soil raise the osmotic potential of the soil solution and prevent crop uptake of water
(Velez, 2023). Southern magnolias do well in wet and well-drained soils, and having high salt
levels will affect the germination and emergence of magnolia, leading to stunted growth and
poor spreading of leaves.
Hypothesis and Predicted results
We hypothesize that Southern Magnolias is sensitive to high soil salinity and that its growth
and development in soils with high salt level will lead to stunted growth.
For our study, two controlled groups will be observed for which different soil
conditions will be applied. The experiment will take place over two weeks to observe the
effect of soil salinity on the germination and emergence of southern magnolias. One group
will observe the sensitivity of southern magnolia in soil with high salt levels adjacent to a
