Potential hydrogen, more often known as pH, is the measure of the acid levels of a solution and is represented by a number from one to fourteen. If a substance's pH is six or lower, it is considered an acid, but if a substance is measured at eight or higher, it is considered basic, meaning it has a lesser acidic value. (Willi Evans) Hydrogen is the element that triggers the formation of acids in the soil. Therefore, the higher the potential hydrogen level, the more acidic the soil. (Rachel Lovejoy)As indicated by the digital pH scale, typical soil pH is between 6.0 and 6.8. However, each plant requires a different soil pH to grow properly. Additionally, plants grown at pH extremes could potentially exhibit characteristics such as: gaps in nutrient availability, poor balance, poor development, and the presence of highly concentrated minerals that are harmful to plants. (Rachel Lovejoy)Based on the common effects of high acid solutions, plant growth is expected to increase and decrease due to the pH level of the soil in which they are grown. Most common garden plants will grow well in neutral to neutral environments. slightly acidic soil. (Organic gardening) Radishes will be the experimental plant for this test. Radishes prefer well-drained, loose soil, rich in organic matter, free of stones and a pH of 5.8 to 6.8 (Cornell University). According to this, the radishes in this experiment should have increased growth in soils with lower pH. In addition to affecting how nutrients are distributed in growing plants, pH levels also influence the activity of microorganisms that add to the decomposition of organic matter. Too high or too low a pH can also interfere with the effectiveness of the paper composition. (NCBI) The form of phosphorus and its availability are too dependent on pH. Potassium tends to be locked in certain areas under layers of clay. Surprisingly, an increase in pH does not reduce available potassium levels. Sulfur is too little affected by soil pH. Micronutrients, namely manganese, iron, copper, zinc and boron, tend to decrease with higher soil pH. (Koranski)Soil is one of the most important elements for the proper growth of a plant. Even the most minor changes in acidity can drastically alter the way it grows. There are plants that are suitable and others that are not. Some household cleaning products can also be toxic to plants, even though they are used in fertilizers. The soil is extremely fine and very specific to different types of plants. A small change can determine whether the plant will grow or not..
