FieldScale - Gravimetric phenotyping and precision irrigation for plant transpiration measurements in the greenhouse or the field

FieldScale Assess plant transpiration rates

Our FieldScales record the loss of weight of every pot with high precision and computes transpiration dynamics and water use efficiency for every single plant. Irrigation activities can be automated with high accuracy and reliability – even during the weekends!

  • Assess transpiration rates of plants fully automatically and in high-throughput
  • Assess water use efficiency fully automatically
  • Design and automate all irrigation activities (optional) in high Precision and reliability

FieldScale is designed to accommodate bigger and unlimited number of pots up to 300 kg. The scales can be used in climate chambers, labs, greenhouses and even under field conditions.

Spot genotypes with improved tolerances towards drought

Providing genotypes with improved tolerances towards drought has become a major focus in science and breeding programs around the world. Assessing water status has become a basic research method, which is increasingly performed by gravimetric measurements. The power of gravimetric measurements lies in its simplicity and the ability to gain integrated and resilient data over the day. We developed FieldScale as a robust and affordable solution for assessing the transpiration rates of hundreds of plants.

Software

Design, control and track your experiments anywhere in the world. All data is stored locally on the system and processed on a server that comes with the gravimetric systems.

Example dataset

In one of his recent papers in the Journal of Experimental Botany Vincent Vadez et all. have shown various of examples of how FieldScale can accelerate your drought screening routines. More information about their research can be found at their website .

Phenotyping for water saving traits

Using the high measuring frequency of FieldScale enables you to measure absolute differences in transpiration and its dynamics over the course of the day. In this study Vadez et al. 2015 assessed transpiration rates of two different Pearl Millet genotypes with Phenospex FieldSales. (VPD at noon noted in the graph). One genotype (PRLT) shows significantly less transpiration at high VPD. This “water saving trait” is of a benefit in a drought scenario and leads to higher yield. Please note that leaf area in this experiment was assessed with Phenospex PlantEye laser scanner.

Combine sensors data:

It is possible to combine FieldScale data with PlantEye measurements and with environmental data from our weather station.

PlantEye - Spectral 3D plant sensor

PlantEye automates phenotyping in 3 steps:

  1. PlantEye Scans plants and creates 3D files
  2. 17+ plant parameters are calculated
  3. Plant data is Visualized and Analyzed

PlantEye delivers 17+ parameters ready to be analyzed! Read more about the parameters and our automation process.
