🌍 7:30 AGRIC INFO: LAND SURVEYING IN AGRICULTURE—THE EYES OF THE FARMER BEFORE THE HOE TOUCHES THE GROUND
Before the first seed is planted, before the foundation of a poultry house is laid, and before a fishpond is dug, there’s one silent but powerful activity that determines success or failure; land surveying.
Many farmers rush into cultivation without understanding their land. Yet, in modern agriculture, knowing your land is as vital as knowing your crops. Land surveying is the science and art of measuring, mapping, and understanding the shape, slope, boundaries, and elevation of a piece of land. In short, it tells you what the land looks like beneath your feet before you invest in it.
Meaning and Importance
Land surveying in agriculture means using tools and techniques to determine the boundaries, slope, water flow direction, soil elevation, and land suitability for farming activities. It helps farmers plan farm layout, drainage, irrigation systems, roads, and building sites accurately. Without it, we often end up wasting resources constructing structures on wrong spots, misjudging slopes, or losing fertile soil to erosion.
In fact, agricultural surveys are now key to precision farming, where every centimeter of land is mapped and managed intelligently.
Techniques Used in Agricultural Land Surveying
Surveying can be done manually or digitally depending on available resources:
Traditional Techniques: Use of compasses, chains, and leveling instruments to measure distances and elevations manually. It’s affordable but time-consuming.
GPS and Mobile Apps: Smartphones equipped with apps like SW Maps, GPS Fields Area Measure, or QField can now measure plots, determine slopes, and even export farm maps. Many young Cameroonian farmers already use these to plan their one-hectare farms.
Drone Surveying: Advanced farmers and agribusinesses use drones to capture aerial images and generate topographic maps. This helps detect drainage issues, crop stress, and land irregularities.
GIS (Geographic Information Systems): This combines map data and soil information to analyze land use potential and monitor changes over time.
Uses in Agriculture
Farm Planning: Dividing land into plots, locating irrigation lines, roads, and drainage channels.
Erosion Control: Identifying slopes and designing contour farming systems to prevent soil loss.
Water Management: Mapping natural water flow for efficient irrigation and pond construction.
Boundary Security: Avoiding land disputes by knowing exact limits of farmland.
Soil and Crop Management: Combining survey data with soil maps helps determine the best crops for specific zones of a farm.
In Simpler Terms
Surveying tells a farmer, “This part of your land is high, don’t build your pond here.”
It says, “Water flows this way, so plant your vegetables there.”
It helps us farm smartly instead of farming blindly.
A Way Forward for Our Young Technicians
With free mobile tools and training, every young technician can now become a local land surveyor—helping communities plan farms, reduce waste, and design better rural infrastructure.
As we move toward digital and precision agriculture, land surveying should no longer be a luxury it’s a foundation of sustainable farming.
So, before you touch your hoe or plant your maize, first take your phone or measuring tape and “survey your farm because smart farming begins with knowing your land.”
