Plant light interception efficiency is a key determinant of carbon uptake by plants; plant productivity over seasonal time-scales is approximately proportional to intercepted light. Canopy architecture, leaf area, leaf angle distribution, and leaf dispersion are determinants in the light distribution and interception within the canopy. In horticultural crops pruning strategies can optimise tree structure and…
IoT connected dendrometers from ICT International provide measurement logging and connectivity making them ideal for measurement of tree or plant growth, either through diameter (point dendrometer) or circumference (band dendrometer). The range of IoT connected devices are detailed below, including node options for each dendrometer type.
Frost damage to plants can have large impacts on crop yield and quality. Protection of crops during frost events is dependent on the accuracy of plant temperature predictions. Quite often, air temperature is not a reliable predictor of timing, duration and severity of frost events because plant canopy temperatures can be significantly different than air…
An infrared thermometer measures radiant energy. This radiation is simply “light” that is slightly outside the human eye’s sensitive range. All objects radiate infrared energy. The intensity of infrared radiation is proportional to the absolute temperature (°K Kelvin) of the object. Infrared thermometers produce no “intrusion error.” A hot object “target” is radiating its infrared…
Leaf wetness refers to the presence of free water on the canopy, and is caused by intercepted rainfall, dew, or guttation. The duration of the time period during which the leaves are wet is generally referred to as leaf wetness duration (LWD). Leaf wetness is a concern for the development of disease and the dispersal…
NDVI (Normalised Difference Vegetation Index) is calculated from measurements of electromagnetic radiation reflected from plant canopy surfaces. NDVI is a standardised index use to measure the state of plant health. Leaf chlorophyll absorbs red light (approximately 680mm), and the cellular structure of the leaves strongly reflect near-infrared light, approximately 730mm. When the plant is water…
The PWS-100 Precision Scale continuously measures applied irrigation quantities or rates of transpiration in small to medium size potted plants. Plants are placed on the scale and the weight is transmitted continuously at user defined intervals. The amount of weight over time is a direct measure of water applied to, or loss from the plant.
The SFM1x Sap Flow Meter is an IoT sap flow sensor for the measurement of tree and plant water use. IoT connection via LoRaWAN or NB-IoT.
