How does soil pH affect plant griwth?

Answer 1

Yes it does. Different species of plants ar adapted to different levels of soil acidity.

Answer 2

Acids in the soil increase the rate at which elemental ions are released. Many molecular ions are more soluble in low pH solutions. Protons can help release cations that are bound to soil particles (cation exchange). Soil pH affects the availability of plan nutrients. Acidic soils (low pH) tend to be found in regions where the decomposition of organic matter results in production of Carbonic acid, Phosphoric acid, or nitric acid. Alkaline soils (with high pH) are common in regions with large amounts of limestone. Most plants live in soil with pH between 6 and 7. Some (ex. tomatoes) grow better in acidic soils, while others need alkaline soils (pH 8).

Answer 3

Plants grow best in a pH range that is specific for each individual plant. If the pH is not in that range they can not absorb the nutrients necessary for survival. For example: Rhododendrens need acid soil (low pH), they will have trouble growing in basic (high pH) soils. Rhododendrens can not compete with other plants that grow well in a high pH range and rhododendrens will not be found there.ffFmkdcnhfv bvfhgf gfhfhfhfhfhfhfchfgghddhjshfgdjsjsgdgfgfhdhjsjh udhddhdhdhdhhdfhfhfhfh

Answer 4

Some plants grow in sand, some in clay, some in very fertile soil, some in almost any type of soil. Different plants require different pH levels of soil, and some require certain water conditions. All these determine what plants will grow in a given soil.

Answer 5

The soil has to have lots of nutrients. It has to have neutral pH.

I had this question for my science homework one night and that is what I got as an answer. I do not know if it is correct, so I'm warning you now so you don't blame me for the wrong answer (if it is wrong).

Answer 6

The pH is the measure of acidity or alkalinity of the soil (or any other substance for that matter). pH is measured on a scale of 1 (extremely acidic) to 14 (extremely alkaline).

In general most plants grow best within a narrow pH band (normally 5.8 to 6.8) although the actual figure varies slightly depending on the crop. Certain plants such as Camellia and Azaleas prefer slightly acidic soil.

When the pH of the soil moves beyond these parameters chemical reactions in the soil (those that are driven by pH) can cause micro and certain macro elements to "lockup" in chemical compounds that are either non-soluable or are in forms that cannot be readily absorbed by the plant.

What happens then is the plant starts to exhibit signs of nutrient deficiency and can ultimately die.

Extremes in pH can also kill or damage the delicate root hairs on the roots, further compounding the problem of water and nutrient absorption.

Answer 7

It refers to the acidity or alkalinity of the soil.

Answer 8

The pH of an ordinary plant cell is around 6, so soil having more than 8 and less than 5 pH affects plant growth due to alkaline and acedic soils respectively.
