Soil Compaction | Field Scout Soil Compaction Meter

Why measure soil compaction?

The soil is the plant's reservoir of water, nutrients and oxygen. Compacted soil has less pore space to store what the plant needs. Soil compaction prevents moisture penetration, reduces fertilizer and chemical uptake, creates conditions for anaerobic microbes to build up and hinders plant root growth. In some cases, yield losses can run as high as 30% due to compaction alone.

• Penetration resistance measured by internal load cell
• Compaction data is displayed in PSI or kPa (1 psi = 6.9 kPa)
• Connects to any GPS receiver that has a serial output option**
• Equipped with internal data logger and RS-232 port
• Records 772 measurements (579 with added GPS/DGPS option)
• Configure and download meter with FieldScout software (included)*

* Spectrum's PC cables connect to a 9-pin serial port. USB-Serial adapter (item 3661USB) required for
connection to computers with only USB ports.
** GPS interface requires two cables. The GPS/DGPS cable (item 2950CV5) is available from Spectrum.
A PC serial interface cable supplied by the manufacturer of the GPS receiver is also required.

Monitor overall soil compaction and quality, quick and effectively with this digital penetrometer.

The #1 source of yield loss in agriculture, soil compaction prevents moisture penetration, reduces fertilizer and chemical utilization and hinders plant root growth. In some cases, yield losses can run as high as 30% due to soil compaction. Don't let it go unnoticed.

Soil Compaction meters are used to determine the density of soil and other material. An operator pushes a rod with attached (ASAE standard) cone into the ground. The resistance of the cone as it is pushed in the ground is measured and recorded in the memory of the compaction meter. The depth of the cone below soil surface is also measured and recorded in memory.

Compaction data is recorded and displayed at one inch intervals, in PSI or kPa. Built-in datalogger eliminates the need to record data manually. Included software allows user to download data, change logger settings and configure the meter.

Measure, log, and review data with the SC-900 Soil Compaction Meter to make better soil management decisions based on data specific to your field. Identify and address specific problem areas on-site and in real time.
