What are Acid-Loving Plants That Grow in Acidic Soil

Acidic soil refers to soil that has a pH level that is less than 7. That basically means that, soil that is below 7 on the pH level meter is acidic. When it comes to soil pH levels the lesser the pH level the greater the acidity level. Acidic soil is considered to be “sour”, whereas its opposite alkaline soil which has a pH level above 7 is considered to be “sweet”. You took a soil test and discovered that your soil is acidic, well that should not stop you from growing plants anymore. A number of vegetables, flowers and flowers actually prefer and grow well with acidic soil.

What causes the soil to become acidic?

Organic matter and minerals are basically acidic in nature. When the organic matter breaks down and the material starts to decompose that causes the soil pH level to acidify. Organic matter promotes microbial activity by microorganism that also causes the soil to acidify. Moreover, some plant growth produces organic acids into the soil that acidifies the soil.

The use of chemical fertilizer causes the soil to become acidic. Chemical fertilizers with high nitrogen synthetic are ammonia based, the continuous application of this fertilizer increases soil acidity.

Leaching because of irrigation, excessive rainfall or excessive watering causes the soil to become more acidic. Excessive water washes away all the important nutrients like magnesium, potassium and calcium. Lack of these nutrients causes the soil pH level to drop, which in turn causes the soil to become acidic. Additionally, rainfall is already slightly acidic in nature.
