Agriculture Land Area Calculation: Explained in Detail

Table of Contents

Agriculture land area calculation is essential for optimising farm management and valuation. Let’s discuss the reliable techniques to achieve precise measurements and enhance land use efficiency.

How to Measure Agricultural Land?

Time needed: 2 minutes

Measuring agricultural land is essential for many tasks, like planning crop areas or setting up land sales. Here are some simple methods to do it right.

Tape or Rope Measurement:
This straightforward technique uses a tape measure or rope. Measure the land’s length and width and multiply these to get the area.
Pacing:
A surveyor walks the land’s edges, counting steps. They convert these steps to distance using a known step length.
Surveying Equipment:
Tools like theodolites, total stations, and GPS devices offer precise land measurements. These tools help make detailed land maps.
Remote Sensing and GIS:
New technology in remote sensing and Geographic Information Systems (GIS) changes how we measure land. Satellites and drones gather detailed land data for accurate mapping.

Essential Tools and Methods for Measuring Agricultural Land

Measuring land accurately needs the right tools and methods. Here’s a look at the best tools for this job.

Total Stations are great for detailed land surveys. They mix electronic distance checks with transit features. You can send data straight to computers.
GPS Devices use satellites for exact area measurements. They work well for big land surveys.
Geographic Information Systems (GIS) gather and organise data for planning and mapping land.
Drones take high-quality aerial photos. They help make maps and 3D models of land.
Laser Rangefinders offer fast and precise measurements, helpful during field surveys.
Methods like triangulation, exploring, photogrammetry, and remote sensing improve measurement accuracy. They break down areas into triangles, create maps from photos, and use satellite data for detailed checks.

Regional Differences in Agricultural Land Measurements

In India, the units used for land measurement can vary significantly from one region to another. Here is a closer look at how these units differ across various parts of the country:

North India

Punjab and Haryana:
- Bigha: Approximately 0.25 hectares.
- Kanal: Roughly 5445 square feet.
- Marla: Typically measures 272.25 square feet.
Uttar Pradesh:
- Bigha: Ranges from 0.25 to 0.33 hectares.
- Biswansi: A smaller unit often used alongside bigha and biswa for detailed measurements.

West India

Rajasthan:
- Bigha: Generally around 0.25 hectares.
- Biswansi: Commonly used with bigha and biswa.
Gujarat:
- Vigha: Usually about 0.16 hectares.

East India

West Bengal:
- Katha: Approximately 720 square feet.
- Bigha: Comprised of 20 kathas, roughly 0.1338 hectares.
Bihar:
- Katha: Generally 1361.25 square feet.
- Bigha: Consists of 20 kathas, about 0.1338 hectares.

South India

Challenges Faced While Measuring Agricultural Land Accurately

Measuring land accurately can be tricky. Here’s a look at some common problems people face.

Different Units: In various places, units like bigha, katha, and penny are used. These differences make it hard to standardise measurements.
Costly Tools: Advanced tools like GPS and GIS offer great accuracy but can be expensive. This makes it tough for small landowners to use them.
Human Error: Mistakes by surveyors can lead to wrong measurements. Ensuring accuracy is crucial.
Outdated Records: Old and scattered land records create legal and administrative issues.
Natural Obstacles: Things like dense vegetation or seasonal changes affect measurements. Special equipment is often needed to deal with these.

Conclusion

To ensure accurate agriculture land area calculation, it’s essential to choose the right tools and understand local measurement units. This knowledge simplifies the process and enhances precision in your calculations.

Frequently Asked Questions

1. How is the area of agricultural land determined?

To find the area, multiply the land’s length by its width in feet to get square feet. Then divide by 43,560, the number of square feet in an acre, to convert to acres.

2. What is the formula for calculating the area of land?

To find the area of a rectangular or square plot, multiply the length by the width. For irregular shapes, divide the plot into regular shapes, calculate each area, and add them together.

3. What determines the value of agricultural land?

To determine agricultural land value, consider factors such as location, market conditions, farm income, comparable sales, soil quality, cropping history, and the size and use of the land.

4. What defines agricultural land?

Agricultural land includes areas used for growing temporary crops like cereals, permanent crops, and land for grazing. It also covers market gardens and fields resting temporarily.

5.How can you determine the number of acres in a land parcel?

To find out how many acres you have, multiply the length by the width of your land in feet to get square feet. Divide that number by 43,560 to convert to acres.

6. How do you measure different land shapes accurately?

To calculate the area of land: multiply length by breadth for rectangles, side length squared for squares, and for trapeziums, use 0.5 times the sum of parallel sides times the height. Uneven shapes require more complex methods.
