Weather Monitoring - Environmental Meters - Light Meters
As the driving force for photosynthesis, light is fundamentally important to crop production. Plant growth and development is significantly influenced by both the quantity and the quality of light. Light energy is relevant to other factors too. The ET calculation (evapotranspiration) for irrigation scheduling uses solar radiation as a key variable. Leaf wetness periods or high humidity, which affect disease pressure, can be mitigated with sunny days versus cloudy days. It is essential that growers understand this important variable in order to efficiently produce quality plants.

Nutrient Management - Chlorophyll Meters - NDVI
Essential tools for managing your nitrogen program! One indicator of plant stress is light absorption and reflectance. Since chlorophyll absorbs red light, low reflectance in this band indicates a healthy plant. Conversely, the cellular structure of healthy plants reflects light in the near infrared band. When plants are under stress, red band reflectance increases and near infrared band reflectance decreases. The Normalized Difference Vegetation Index (NDVI) is a unit of measure designed to factor both red and near infrared reflectance. NDVI measurements can range from -1 to 1, with higher values indicating greater plant health.

FieldScout - Model TCM 500 NDVI - Turf Color Meter
Measures reflected light from approximately a 3 inch (7.6 cm) diameter section of turfgrass. Turfgrass quality is visually evaluated by human assessors based on a scale of 1 (dead grass) to 9 (perfect grass) in the current assessment method. This evaluation practice has several disadvantages and therefore, there is the need for a better evaluation technique. Individual biases are inevitable and lead to some level of inconsistency, even among the most ...

Soil Moisture - FieldScout TDR Meters
Why measure soil moisture? Soil moisture plays a key role in the life of the plant. Nutrients in the soil solution provide the plant with the food it needs to grow. Water is also essential for regulating plant temperature through the process of transpiration. Plant root systems are better developed when growing in moist soil. Excessive levels of soil moisture, however, can lead to anaerobic conditions that can promote the growth of plant and soil pathogens.

Soil Moisture - Tensiometers
Understanding Soil Moisture: Tension Soil moisture tension is the measurement of how strongly water is held in the soil. Water is held in the soil by capillary forces as well as the attraction of the water molecule to itself and to electrically charged clay particles. Soil moisture tension is measured in units of pressure (centibars or kilopascals). The tension at which irrigation is recommended depends on the soil and crop, but typically falls somewhere between 30 and 50 centibars*. * 1 centibar = 1 kPa.

Soil Moisture - Soil Compaction - FieldScout SC 900 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.

Soil Moisture Sensors - Irrometer Tensiometers
The IRROMETER Tensiometer is the standard in accurate soil moisture measurement, offering growers an inexpensive and reliable means of measuring soil moisture for irrigation scheduling. An IRROMETER will measure the actual soil water tension, which indicates the effort required by root systems to extract water from the soil. Because the IRROMETER is a true measurement of soil water potential, the instrument is not affected by salinity and does not require site calibration. The IRROMETER is available in several models, with standard lengths of 6", 12", 18", 24", 36", or 48" dependent on the rooting depth of the specific crop. Longer lengths are available by request.
-
Irrometer - Model SR Series - Tensiometer
Measuring soil moisture allows a grower to make informed irrigation scheduling decisions that will improve yields and quality while reducing water, fertilizer, labor, and energy costs. The IRROMETER SR measures soil moisture by interacting with the soil through a porous ceramic tip. As soil dries, it tries to pull water out of the instrument, creating vacuum measured by the gauge. This is a direct, physical measurement of the same tension plant roots ...
