In Owari Agro you record each plot's number of trees and planting spacing; with that, the system calculates the area in hectares and, with the kilos harvested during the year, shows on the Home screen the kilos per tree and the kilos per hectare of each plot.
What a plot record includes
In Plots > Create plot, the «General information» section asks for:
- «Plot name» and «Plot variety».
- «Planting date» and «Crop type».
- «Number of trees».
- «Planting spacing», in meters: for example, 2 x 1.
- If you've already stumped: «Number of stumpings», «Stumping type» and «Last stumping date».
How it's calculated
- Area (ha): the two planting spacing measurements multiplied by each other and by the number of trees, divided by 10000. For example, 5000 trees planted at 2 x 1 meters take up 1 hectare.
- Kilos harvested: the total kilos from the Harvest task on that plot during the current year.
- Yield per tree: kilos harvested divided by the number of trees.
- Yield per hectare: kilos harvested divided by the area.
Units are fixed: meters for spacing, hectares for area and kilos for the harvest. If a plot has no planting spacing, you see its kilos and yield per tree, and yield per hectare shows «no area recorded» until you fill it in.
Where to see it
In Home > «Indicators»:
- Plot yield: pick a plot and see its kilos accumulated in this year's harvest, the yield per tree (and over how many planted trees) and the yield per hectare (and over how many planted hectares).
- Comparison by plot: all plots in one table with the kilos harvested, trees, yield per tree, area, kg/ha and plot age, plus the date of the next fertilization when there is a plan.
- Tree inventory: how many plots have their trees and spacing recorded, their total area in hectares and how the trees are split by variety.
Plot age is counted from the most recent of these dates: planting, the last stumping, or the Stump or Renew tasks. Only plots with a number of trees are included. If the farm has several crops, the «Crop:» selector shows the indicators for each one.
From yield to cost
Drawing the plot on the map doesn't change this calculation: the area comes from the trees and the spacing, as explained in mapping your plots. To put yield side by side with what each plot costs, continue with profitability and costs by plot.
