Kalkitusta

Kalkitusta is a Finnish term referring to the process of applying lime to soil. This agricultural practice is primarily aimed at correcting soil acidity, a common issue in many regions that can hinder crop growth and nutrient availability. By raising the soil's pH level, kalkitusta makes essential nutrients like phosphorus and potassium more accessible to plants, promoting healthier root development and overall plant vigor.

The application of lime can also improve soil structure. It helps to aggregate soil particles, leading to better aeration and drainage, which are crucial for healthy root systems. This improved structure can also enhance the soil's ability to retain moisture, making it more resilient during dry periods. Furthermore, lime can reduce the solubility of toxic elements like aluminum, which can be present in acidic soils and inhibit plant growth.

The type of lime used and the amount applied depend on the specific soil type, its current pH, and the intended crop. Common forms of lime include calcium carbonate and dolomitic lime, the latter also providing magnesium, another essential plant nutrient. Kalkitusta is typically performed during the off-season, such as autumn or spring, to allow the lime to react with the soil before planting. Regular soil testing is recommended to determine the necessity and optimal timing for kalkitusta.
