Why plants grow poorly on very acid soils: are ecologists missing the obvious?

Factors related to soil acidity are considered limiting factors for plants in many parts of the world. This study was done to study the impact of hydrogen (H +) toxicity which the ecologist seems not to explain as an explanation of the reduction in plant growth observed in highly acidic soil. Plant growth is racial according to the increase in acidity of grass Holcus lanatus L. (Yorkshire fog) and tree Betula pendula Roth (Silver Birch). Soils and seeds are collected from four Scottish places covering various acids (organic matter and minerals) to more alkaline-rich soils. The location and its pH (1: 2.5 fresh soil: 0.01 M CaCl 2) are as follows: Flanders moss (FM), pH 2 ± 0.03; Kippenrait Glen (KP), pH 8 ± 0.05; Kinloch Rannoch (KR) pH 1 ± 0.16; and Sherihumia (SMM), pH 3 ± 0.11. Two groups of H. Ranatas, FM and KP and three B. Proliferation rates of pendulas (SMM, KP and KR) were measured in nutrient solution cultures with pH 0 (H. Ranatas only). The result of 0,0 indicates that the population of acidic organic soil (FM) is resistant to H + and the acidic mineral soil (SMM) species is resistant to Al 3+, but not necessarily resistant to H + There is no indication. These results support that individual populations are adapted to H + or Al 3 + toxicity, depending on the soil characteristics of the collection sites. The fact that plants acclimate to H + toxicity supports the notion that this is an important element in highly acidic soil.

Is the soil alkaline, neutral or acidic? Most plants grow best in neutral pH soils, but some plants like slightly acidic and other slightly alkaline soils. What is the pH of the soil in your garden? What is the pH of the water in contact with the soil? You will learn about this scientific project. When soil and water meet, their acidity interacts and affects both. After all, water is discharged and the acid content of the soil is slightly different. Soil acidity is very important as soil acidity determines which plants can grow there and how to easily extract the necessary nutrients for the roots to survive. For water and soil, acidity is measured on the pH scale, which is a negative logarithmic scale, and each value increases or decreases by 10 times. The ratio is 7 in the center and the pH is neutral (pure water etc.)

The results indicate that the type of acidic organic soil (FM) is H + resistant while the type of acidic inorganic soil (SMM) is resistant to Al 3+, but not necessarily H + resistant.
