For the experimental aspect of the research report, four sets of two plants are to be studied. They must either be checked according to size for the same height, or started from seed to ensure equality. Two identical sets of roses are to be cultivated, as well as two sets of corn plants. The flora must all be given the same amount of water and sunlight each day. The only variable to be changed is pH. One of each set will be planted in the acidic soil, and one set will be rooted in a basic soil.

After the research is conducted, pH will be presumably have a strong effect on the growth of both plants. It is believed that the rose's growth will be more pH dependant than the corn plants.

The pH level of the surrounding soil can have extreme results on the growth rate and overall health of a plant. The pH is technically defined as the negative base ten logarithm of the effective hydrogen ion concentration in gram equivalents per liter. It is measured on a scale of 1-14, with each reading being shown as an acid, base, or a neutral solution. If the measurement is less than 7, it is considered an acid. Such acids are vinegar, orange juice, and battery fluid. If the measurement is o

Two plants that may have adverse reactions to different pH levels are corn and roses. Corn is a much simpler plant, with a very little list of requirements to grow and thrive. It grows fast, with only light and small amounts of water. It has an erect, solid stem unlike most other grasses. It can vary widely in height, with some dwarf varieties only reaching a maximum height of two feet. The rose is a flower grown mostly as a gift and for its sweet-smelling fragrance. Today, it is most popularly cultivated as a garden flower. The genus contains 100 species, with most being native to the North Temperate Zone. With selected breeding, many hybrids and new varieties have arisen. Several hundred new species of rose are bred each year. In the U.S. 20 million plants are commercially sold for cut flowers, with another 40 million being sold for landscape and ornamental use.

Soil pH has several effects on the plant that lives in it. First, the chemical reaction between plant roots and nutrients can be harmful and/or fatal. Second, the availability of nutrients is raised with the proper soil pH. The soil pH can also influence plant growth by its effect on activity of beneficial microorganisms. Bacteria does not easily decompose in strongly acidic soils. This keeps organic matter from breaking down, thus resulting in an accumulation of organic matter and binding the nutrients that are held in the organic matter. Soil pH can be influenced by a variety of factors, such as

1) Rainwater leaching away basic ions.

1) calcic limestone, also known as ground limestone.

Corn needs to be planted about an inch deep in order to make certain that the seeds do not rot. To start a crop, it is suggested that the grower wrap an ounce of seeds in a moist paper towel and place it in a plastic bag. When small white roots are visible, they must be moved to a pot so their growth remains constant. Then the grower should run a piece of plastic cellophane over the pot removing it when the plant emerges from the soil.

To measure the pH of the two solutions, many methods have been invented. Some of the most popular ways include drops, pills or powders. Each of these kits uses certain color indicators and dyes such as litmus paper. They come with a color chart to match with the pH level and are sold at most garden stores. This method is simple but less accurate. An estimate may be made by allowing the sample to become saturated with the dye for a few minutes. Also, electronic digital battery operated meters are available. These usually cost more, are temperature and battery dependent, but have the advantage of being read easily and quickly.

The first variable to be considered for the rose's needs is water. These beautiful flowers love water and should be given plenty of it. They should be showered with at least 2 and 1/2 centimeters of water per week during the summer growing season. This equates to roughly one gallon of water so they need a good supply each week. They should not be in standing water, however. Only moderately moist loam is best for roses. The soil is kept consistently wet since allowing it to dry out between watering can adversely affect the growth rate of the roses.

The amount of lime to be added is affected by a number of factors including soil pH, texture, structure, and amount of organic matter. In addition, the crops or plants to be grow
