ID: #659744
Description
Dolomitic lime is a type of agricultural lime that is primarily composed of calcium carbonate and magnesium carbonate. It is used to improve soil quality and pH levels in agricultural and gardening applications. Dolomitic lime can help plants grow by addressing several key soil-related issues: Adjusting Soil pH: One of the primary functions of dolomitic lime is to raise the pH of acidic soils. It does this by adding calcium and magnesium ions to the soil, which helps neutralize excess acidity. Most plants grow best in soils with a slightly acidic to neutral pH range (around 6.0 to 7.0), and dolomitic lime can help bring soil pH within this optimal range. When soil pH is too acidic, essential nutrients become less available to plants, leading to nutrient deficiencies and poor growth. Enhancing Nutrient Availability: Dolomitic lime not only raises the pH but also improves the availability of essential nutrients in the soil. Adequate calcium and magnesium levels are vital for plant growth and development. When these nutrients are deficient, plants can suffer from issues like blossom-end rot in tomatoes and poor root development. Reducing Toxicity: In soils with excessively high levels of acidity (low pH), certain toxic elements like aluminum and manganese can become more soluble and available to plants. Dolomitic lime helps reduce the toxicity of these elements by raising the pH and making them less accessible to plants. Improving Soil Structure: The calcium in dolomitic lime can help improve soil structure by flocculating clay particles. This means it helps bind small soil particles together into larger aggregates, which enhances soil aeration, drainage, and root penetration. Improved soil structure allows plant roots to access oxygen and nutrients more easily, promoting healthier growth. Promoting Beneficial Microorganisms: Proper soil pH and nutrient availability encourage the growth of beneficial soil microorganisms, such as mycorrhizal fungi and beneficial bacteria. These microorganisms can aid in nutrient uptake and overall plant health. Pelleted Dolomitic Limestone (57.7% CaCO 3 , 33% MgCO 3 ). Cal Carb Equivalent 96.9%.
