What kind of soil is acidic soil
An introduction to what kind of soil is considered acidic will be discussed. Next, the editor will provide an explanation.
Acidic soil has a high humus content, appearing dark brown, with a thick layer, loose texture, good water permeability and breathability. It feels soft when held in the hand, does not easily clump when wet, does not fizz when watered on the surface, the water is turbid, and it can quickly penetrate into the soil. It is also easy to dig.
How to deal with acidic soil
Acidic soil refers to soil that lacks alkali metals and alkaline earth metals, with a high absorption of H+ ions and a pH value greater than 7. The following are the causes of acidic soil.
Rainwater containing carbonic acid can form acidic soil; the metabolic products of microbes and plant roots can also form acidic soil. The decomposition of organic matter produces organic acids that can form acidic soil, and the oxidation of ferrous sulfide to sulfate can also form acidic soil. The decomposition of chemical fertilizers can also result in acidic soil.
If the soil becomes acidic, the alkaline metal ions and H+ ions adsorbed on the clay and humus are replaced, causing a deficiency of metal ions in the soil, which makes the soil acidic.
What plants are suitable for acidic soil
Acidic soil refers to soil with a pH value below 7, which mainly includes yellow soil, red soil, lateritic soil, ash soil, and red soil, etc. Acidic soil has abundant precipitation and strong leaching action.
Its base saturation is relatively low, and its acidity is very high. The use of acidic soil is widespread in the world, mainly applied in agricultural growth and occupies a very important position.
1. Acidic soil is suitable for planting flowering plants such as gardenia, ferns, hydrangea, colorful leaves, azalea, orchids, purple dayflower, etc.
2. Flowering plants suitable for weakly acidic soil include jasmine, five-needle pine, palm trees, begonias, primroses, cyclamen, camellias, red Riding Hood, Michelia, camellias, lilies, gladiolus, tuberous begonia, white magnolia, etc.
3. Flowering plants suitable for slightly neutral to slightly acidic soil include chrysanthemum, hyacinth, perpetual primrose, asparagus, fuchsia, purple magnolia, kaffir lily, raffia, osmanthus, taro, crabapple, etc.
4. Vegetables and plants suitable for planting in acidic soil include watermelon, berry plants, strawberries, potatoes, sweet potatoes, turnips, marigolds, lilies, azaleas, oaks, cedars, heather, oaks, hemp, etc.
【Summary】
Soil with a pH value less than 7 is considered acidic. pH value refers to the acid-base level. Generally, leaf mold soil and peat soil are acidic, which are considered acidic soil. Pine needle soil and bog soil are strongly acidic and are also considered acidic soil.
If you want to adjust the pH of the soil to make it more acidic, you can mix sulfur powder or ferrous sulfate into the soil during soil preparation to lower the pH value. Normally, you can also water the soil with fruit peel water to make it more acidic.
