Irrometer Tensiometer are excellent indicators for irrigation scheduling. With four different depths to choose from, they tell you how hard plant roots are working to draw water from the soil. Use model “R” for general use with field and tree crops or model “LT” for coarse soils or greenhouse media. Service kit (one required) includes handheld vacuum pump, fluid concentrate, 25 chart forms and reference book. Available in 6", 12", 18", 24", 36", or 48“ lengths. Irrometer models are also available with Remote Sensing Unit (RSU) 4-20 ma transducers for use with electronic data logging equipment, including our Watermark Monitor.
Place a Watermark Sensor in the root zone of your crop or turf and use the handheld digital meter to get an instant reading of moisture tension from 0 (saturated) to 200 (dry) centibar. Use in conjunction with evapotranspiration estimates to fine-tune irrigation scheduling. One digital meter reads all your sensors. Each sensor includes a 5ft/1.5m extendable cable. With the Watermark Adaptor, you can also use a Watermark sensor with our Watch Dog systems.
The IPM Scope combines a digital camera, precision optics, and LED lighting into a powerful handheld microscope and imaging software package. Zoom in with its versatile 40 or 140X magnification on fine details of plant disease symptoms, insects, or anything else too small to see with the naked eye. Instead of straining to look into a tiny eyepiece, place the IPM Scope over the leaf and view the magnified image right on your computer screen. Capture still images, easily add descriptive labels, make measurements, or even draw right on the image.
The SPAD 502 Chlorophyll Meter instantly measures chlorophyll content or “greenness” of your plants to reduce the risk of yield-limiting deficiencies or costly over fertilizing. The SPAD 502 quantifies subtle changes or trends in plant health long before they’re visible to the human eye. Non-invasive measurement; simply clamp the meter over leafy tissue, and receive an indexed chlorophyll content reading (0-99.9) in less than 2 seconds. Assess nitrogen needs by comparing in-field SPAD readings to university guidelines or adequately fertilized check or reference strips. Research shows a strong correlation between SPAD measurements and leaf N content.
The Guelph Permeameter is used to obtain accurate measurements of hydraulic conductivity, soil sorbtivity and soil matrix flux potential. These three factors govern how liquid move through an unsaturated soil profile. The Guelph Permeameter is a complete kit consisting of the permeameter, field tripod, well auger, well preparation and cleanup tools, collapsible water container, and vacuum test hand pump, all packaged in a durable carrying case.
The wet sieving apparatus is used to determine the aggregate stability. The standard set includes a shaking machine for wet sieving method (incl. 100-240 VAc adapter), suitable for 8 sieves, aluminium cans Ø 62.5x44 mm, sieve cans Ø 39x39 mm with sieve opening 0.250 mm and sieve surface of 10.2 cm2. The wet aggregate stability is determined on the principle that unstable aggregates will break down more easily than stable aggregates when immerged into water.
The equipment is suitable for determination of pF-curves in the range pF 2.0 - 4.2 (0.1 - 15 bar of suction). Furthermore the sets are suitable for the calibration of soil moisture blocks or soil moisture measurement equipment. The standard set contains amongst others: two extractors with ceramic plates (0.1 MPa, 0.3 MPa and 1.5 MPa, resp. 1, 3 and 15 bar) and accessories, soil sample rings, a pressure control panel and a compressor. Several ceramic plates with soil samples can be placed in the extractor at the same time. The pressure control panel is standard equiped with two manometers 0 - 2 MPa and 0- 0.4 MPa (resp. 0 - 20 bar and 0 - 4 bar). The included compressor (220V - 50 Hz) is specifically designed for this purpose: maximum pressure 2.0 MPa (20 bar), built-in safety precautions, completely guarded and quiet.
To obtain an accurate determination of the particle size distribution of the smallest fractions it is possible to apply the hydrometer method. Hydrometer readings are taken after regular intervals. Sedimentation time and hydrometer readings are used to determine the grain sizes according to the Stoke’s Law. The hydrometer kit, among other items, contains: a number of hydrometers, sedimentation cylinders, a thermometer, a glass container, a heating element with thermostat and stirrer, a soil stirrer and various accessories.
Test your own sand with a complete set of brass sand sieves! Excellent for new construction, testing topdressing sand and bunker sands as well as helpful in testing existing soil profiles. This set will give you a full USGA particle breakdown including 2.0 MM, 1.0 MM, 0.5 MM, .25 MM, .15 MM and .05 MM sizes. Top and bottom pans are also included. Set is 8 inches in diameter, solid brass with bronze screens.
Portable TDR 300 accurately measures soil moisture across the full range of soil moisture conditions. Select from the 12cm or 20cm (4.8in or 8 in) probe rods to suit your measurement depth. Install PVC access tubes and take moisture deeper in the soil profile. The LCD interface provides two modes: volumetric water content and relative water content (irrigation management) mode. • Eliminates guesswork before irrigation • Perfect for all types of soil • Unit: % of the volumetric water content • Resolution: 1.0%; accuracy: ±3% • Data logger • Power: 4 AAA cells • Supplied with 12 or 20 cm probe • Can be connected to a GPS/DGPS system.
The Watermark Monitor is a Data-Logger which automatically takes soil moisture readings. This reading history provides you with a vivid picture of the soil moisture profile your irrigation practices have created. This data can be evaluated to determine ways to improve the irrigation scheduling for optimum result.
• Automatically Reads Sensors • 8 Sensor Capacity • Programmable Reading Frequency • Water graph Software included
• In-Field display of current reading • Download history to a computer • 9 Volt battery included.
Soil Compaction is the number one cause of yield loss and impacts turf quality. Different equipments and tools are accessible with varying features.Data logger based Soil Compaction Meter with Geo referenced mapping facility is also available.
