FruitLook tutorials on YouTube

Let us help you to get the most out of your FruitLook data! 

We want to help you understand your data as well as possible, and we are more than willing to be in touch with you. But, do you just want a short and to-the-point tutorial, some explanation of how something works? We have another solution. We have an active YouTube channel with short videos on FruitLook - we have information on:

- What does Biomass Production tell you?
- How does Biomass production differ from Water Use Efficiency?
- What is NDVI and how to use it? 

- How can you use the Leaf Area Index data?
- And much MORE
 

We keep on making videos and will make them short so you have access to information whenever you may need it.
You can find our channel through

Seasonal analysis - a small dive into what FruitLook can support you with

There are various ways to use FruitLook data to help you answer questions like, “why are the yields in the one block so much higher? Did you irrigate optimally?” This is the first part of a two-part series about seasonal analysis in FruitLook.

Zonal block analysis
You can do a zonal analysis per block with the use of Field comparison under the MyField Analysis tab. Where are my areas that stress first? Are those areas the same from year to year? Does the variation even out after rain? The Biomass Production (BMProd) and Vegetation Index (NDVI) parameters clarify growth variation in a block. Identification of distinct zones can help you decide where to sample fruits or leaves or show where your blocks need additional attention. When looking at the last data set at the end of the season for the cumulative biomass production we can determine where are the truly vigorous growing areas are as well as the weaker ones. This can then be compared to the previous years to see if that pattern is the same or not.

Actual evapotranspiration (ActET) and Evapotranspiration deficit (ETDef) can be used to identify areas where stress occurs first or where water accumulates to promote vegetative growth. If the rain evens out your stress patterns it could be an indication that your irrigation is not fully optimized for all the soil types. This is very common and sometimes you can’t do anything about it, but it is important to be aware of these zones. 

Determining growth problems
With the graph comparison tool, you can compare the BMProd of the growth of different blocks with the same crop type to see if any of your blocks suffered some form of stress during the year which might have affected the yield. The same can be done with the Cumulative Biomass Production parameter.

Comparison of different year seasonal analysis
You can also compare all of the graphs to that of the previous season. Did a field produce less yield than the previous season? You might want to know why. Or do you want to evaluate a change that you introduced during the past season in your crop management? Did this change have the desired effect? 

Irrigation efficiency
By adding your ActET for the whole season you can compare that to your irrigation records. Remember your ActET is NOT just from your irrigation, but any source of water as well including rain and a water table. You can decide to what extent you want to include rain in your irrigation efficiency calculation; as long as you are doing it consistently from year to year.

Yield or income water use efficiency
By adding your ActET you can do a few variations of water use efficiencies. As biomass water use efficiency doesn’t equal yield you can work out your own by yield water use efficiency by using your tonnage per mm or cubic meter of ET. You can do the same with the income of the block. You can use either one to help you make more informed decisions when considering which crop and/or cultivar to plant.

Sensitive cultivars
By loading all your fields of the same crop on the My Graph Comparison we can quickly see which blocks or cultivars showed the highest peaks of stress. From the picture below we can see that Pink Lady B1 showed some of the highest peaks in ETDef during stress which means that that block is considerably more sensitive than some of the other blocks like Pink Lady A1 or Gala 10A.

Spatial vigor variation
Using the Field Comparison tool helps you find variations in the blocks that have only varied from year to year, but also as the season progresses. This can be a focus and something to look into when occurring out of the blue. 

Pivot tables
FruitLook has developed an Excel-based tool using macro’s and pivot tables to assist with same season analysis. This is not recommended for an Excel novice, but for someone familiar with the functionalities of Excel. This tool plots all the weekly data sets for all your fields which you can then further filter according to a category, crop, or even field name. As it makes use of pivot tables and graphs it also automatically calculated the sum of ActET, cumulative Biomass Production, etc. You can also adjust your season and only select the time period you want to see and not the whole 12 months.
