Soil Analysis Equipment

Understanding soil before every planting decision

Soil analysis equipment measures the chemical and physical properties that decide crop performance: nitrogen, phosphorus and potassium, pH, salinity and organic matter, heavy metals, moisture, water potential, bulk density, aggregate structure and compaction. Soil testing laboratories, agriculture ministries, extension services, universities, land reclamation projects and commercial farms use these instruments to recommend fertiliser rates, monitor salinity, screen land for contamination and study soil health. The range covers samplers and grinders for preparation, benchtop and portable nutrient analysers, and sensors for continuous field monitoring. ASFAN supplies, installs and supports soil equipment and helps specify complete soil laboratories.

ASFAN supplies and supports soil analysis equipment for universities, ministries, laboratories and farms across Saudi Arabia.

Balanced fertiliser programmes

Measuring available nitrogen, phosphorus, potassium and organic matter allows fertiliser rates to be matched to crop needs, lowering input costs and reducing nutrient losses to groundwater.

Salinity and pH management

Regular pH and salinity readings help farms in arid regions detect salt build-up early, adjust irrigation and leaching, and select crops that tolerate local soil conditions.

Contamination screening

Portable heavy metal analysers screen agricultural and reclaimed land for lead, cadmium, arsenic and other elements before planting, supporting food safety and land-use decisions.

Water and structure studies

Moisture probes, tensiometers, water potential meters and penetrometers reveal how water moves and roots grow, guiding irrigation scheduling, tillage and soil conservation research.

Frequently Asked Questions

Is a portable soil analyser accurate enough for recommendations?

Portable analysers are well suited to screening, extension work and on-farm decisions. For certification, research or disputed results, samples should be confirmed with benchtop analysers or standard laboratory methods under controlled conditions.

How should soil samples be taken?

Take several cores across a uniform field zone at a consistent depth with a soil auger, mix them into one composite sample, then air-dry, grind and sieve it before laboratory analysis.

Can soil moisture be monitored continuously?

Yes. Data-logging soil meters and wireless moisture recorders store readings at set intervals, so changes in moisture and temperature can be followed through the irrigation cycle without repeated site visits.
