kalkitusmäärien

Kalkitusmäärät refers to the quantities of lime applied in agricultural or forestry practices. Lime, typically calcium carbonate or calcium oxide, is used to increase the pH of acidic soils. Soil acidification can occur naturally over time or due to the use of certain fertilizers and atmospheric deposition.

The optimal kalkitusmäärä is determined by several factors, including the current soil pH, the soil's buffer capacity (which depends on soil texture and organic matter content), and the target pH for the specific crop or vegetation. Soil testing is essential to accurately assess these parameters and calculate the appropriate lime application rate.

Applying too little lime may not effectively raise the soil pH, resulting in continued limitations for nutrient availability and plant growth. Conversely, excessive liming can lead to an overly alkaline soil, which can cause nutrient deficiencies, particularly of micronutrients like iron, manganese, and zinc. It can also negatively affect soil microbial activity.

Kalkitusmäärät are often expressed in units of mass per area, such as kilograms per hectare (kg/ha) or tonnes per hectare (t/ha). The method of lime application, whether broadcast spreading or incorporation into the soil, can also influence the effectiveness and the required quantity. Regular monitoring of soil pH is recommended to adjust future kalkitusmäärät as needed.
