TERRAPURE / SERVICES
Turn soil analyses into fertility maps.
Different parts of a farm may require different decisions. Terrapure combines georeferenced sampling, laboratory analyses and agronomic interpretation to organize soil variability into management units.
Understand nutrient capacity.
Cation exchange capacity, or CEC, is assessed alongside acidity, nutrients and organic matter. Texture, moisture and other selected attributes provide context, rather than reducing soil diagnosis to a single indicator.
The plan defines sampling depths and management units or a sampling grid suited to the area and technical question. Crop, fertilizer, irrigation and yield records help select locations and interpret differences between results.
Map differences to support decisions.
Thematic maps show sampled locations, depth, method and interpretation. Interpolation limits are made explicit: estimated values between sampling points are not measurements taken across the entire surface.
Deliverables include fertility maps, a georeferenced dataset and priorities for each management area. Combining these with information on water, compaction, pesticide residues and soil biota supports discussions about amendments, fertilization and input use with the farm’s agronomy team. Follow-up observations provide a basis for reviewing those priorities.
Common questions.
Does a fertility map determine fertilizer rates on its own?
No. Decisions should combine laboratory findings, crop requirements, production objectives and management conditions with the responsible agronomy team.
How many soil samples are needed?
The number depends on field size, variability, history and the required resolution. Locations and depths are agreed before collection, together with the limits of interpretation for the proposed sampling design.
