Резюме	The soil moisture curve (or soil water retention curve, SWRC) describes the relationship between soil water content and soil matric potential (water tension). It characterizes how tightly water is bound in pores of different sizes: large pores drain at low tensions (wet soils), while smaller pores retain water at high tensions (dry soils). Quantifying this relationship is essential for water balance modeling, unsaturated flow prediction, and assessing plant-available water.	Soil respiration measurement quantifies the rate at which CO2 is released from the soil surface to the atmosphere, integrating contributions from root respiration and microbial decomposition of organic matter. It is a fundamental technique in agronomy, ecology, and climate science, providing insight into belowground carbon cycling, soil biological activity, and ecosystem carbon balance. Measurements are typically made using static or dynamic chambers placed on the soil surface.
