Understanding the Hectare Furrow Slice: Definition, Dimensions, and Applications
The hectare furrow slice is a specific measurement used in agricultural and soil science. It represents the volume of soil that is typically plowed to a standard depth, which is crucial for understanding soil health, fertility, and management practices.
What is a Hectare Furrow Slice?
A hectare furrow slice is defined as the volume of soil that is plowed to a depth of 15 centimeters over one hectare of land. One hectare is equivalent to 10,000 square meters, which is effectively a 100 meters by 100 meters area. This volume measures the topsoil and subsoil, encompassing the tillable soil layer.
Dimensions and Calculations
The exact volume of a hectare furrow slice is calculated as follows:
Volume (in cubic meters): 100 meters x 100 meters x 0.15 meters 1500 cubic meters.
Given that 1 metric ton is equal to 1000 kilograms, and assuming the soil has a typical density of 1.1 to 1.5 g/cm3, the approximate weight of a hectare furrow slice is 2.2 to 2.7 metric tons for every square meter of land.
Considering one hectare as 2.47105 acres, the approximate weight of a hectare furrow slice is:
2200 metric tons (approx. 2.2 metric tons per square meter).
However, this weight is an approximation due to the variability in soil texture and density across different regions and types of soil. Factors such as clay, silt, and sand content, as well as moisture levels, can significantly affect the actual weight and volume.
Applications and Significance
The concept of the hectare furrow slice is essential for several reasons:
Soil Sampling and Analysis: Farmers, researchers, and agricultural experts use the hectare furrow slice to collect soil samples for analysis. Understanding the chemical and biological composition of the soil is crucial for making informed decisions about fertilization, pH correction, and other soil management practices.
Soil Health and Fertility: The hectare furrow slice helps in assessing the overall health and fertility of the soil. By examining the slice, professionals can identify any deficiencies or excesses in nutrients, organic matter, and other critical components.
Tillage and Soil Management: The furrow slice is often used as a standard for measuring the effects of different tillage techniques. It helps in determining how deep plowing affects soil structure, water retention, and crop growth.
Conclusion
The hectare furrow slice is a vital tool in the fields of agriculture and soil science. Understanding its definition, dimensions, and applications can provide valuable insights into soil management and the maintenance of soil health.

Frequently Asked Questions
What is the typical weight of a hectare furrow slice?
The typical weight of a hectare furrow slice is approximately 2200 metric tons, although this can vary based on soil type and density. The exact weight can range from 2,200 to 2,700 metric tons, depending on factors such as clay, silt, and sand content.
Why is a 15-centimeter depth chosen for the furrow slice?
A depth of 15 centimeters is chosen for the furrow slice because it corresponds to the typical plowing depth in many agricultural practices. This depth allows for a thorough assessment of the soil structure and composition without over-probing to deeper layers that may contain different properties.
How does the density of soil affect the weight of the furrow slice?
The density of soil can significantly affect the weight of the furrow slice. Sandy soils are generally less dense than clay soils. Therefore, the weight of the furrow slice can vary depending on the soil type, with clay-rich soils typically being heavier than sandy soils.
