Viljelusmulla

Viljelusmulla, also known as cultivation soil or agricultural soil, refers to the top layer of earth that is used for growing plants, crops, and other vegetation. This type of soil is essential for agriculture and horticulture, providing the necessary nutrients, water, and physical support for plant growth. Viljelusmulla is typically found in the uppermost horizon of the soil profile, known as the A-horizon or topsoil, which is rich in organic matter and microorganisms.

The composition of viljelusmulla varies depending on factors such as climate, parent material, topography, and time. However, it generally consists of a mixture of mineral particles, organic matter, water, air, and living organisms. The mineral particles, which include sand, silt, and clay, provide the physical structure of the soil. Organic matter, derived from decomposed plant and animal material, contributes to the soil's fertility and water-holding capacity. Water and air fill the pores between the soil particles, facilitating root growth and nutrient uptake.

Viljelusmulla plays a crucial role in the global ecosystem by supporting plant life, which in turn supports animal life and human civilization. It is a finite resource that takes centuries to form, making its conservation and sustainable management vital. Practices such as crop rotation, cover cropping, and reduced tillage can help maintain and improve the health of viljelusmulla, ensuring its productivity for future generations. Additionally, the responsible use of fertilizers and pesticides is essential to prevent soil degradation and pollution.
