Almond Production Spreadsheet
The following spreadsheet is a tool to aid in the explanation, budgeting and tracking of almond irrigation, fertiliser and foliar applications.
Water Use & Irrigation
There are several options available for budgeting water use, either by:
- Daily, site specific evaporation data and crop factor % (0-100%) based on the CT trial data. Any profile establishment water has not been taken into account and will be additional to this irrigation program.
- Preselecting a water use figure (ML/Ha) and split according to the monthly %’s of the CT trial data. This can either be calculated with or with out profile establishment water.
- A known water use figure (ML/Ha) with the ability to change the monthly %’s of the CT trial data. This can either be calculated with or with out profile establishment water.
There are four options available for fertiliser application, either:
- Treatment 1 = 240:50:400 (N:P:K) per hectare.
- Treatment 2 = 320:50:600 (N:P:K) per hectare.
- Treatment 3 = 320:50:400 (N:P:K) per hectare. (not a CT Trial treatment, but based on “best bet” nutrient removal calculated from CT Trial)
- User Defined (N:P:K) per hectare.
The suggested program is a minimum requirement with regard to the number of sprays and the listed ingredients. If mixing with fungicides or adding other nutrient products check the associated labels for compatibility and rates. Ensure the spray tank mixes are not too concentrated with ingredients and spraying conditions (e.g. Delta T, temperature,wind, etc ) are appropriate.
Listed values are the average levels obtained for the leaf samples in October,November, December and January for fertiliser Treatment 1 (i.e.240:50:400)
Nutrient Removal Analysis
Whole fruit can be sampled at harvest in a similar method to leaf sampling. The fruit is to be hand cracked into the husk, shell and kernel and and sent to the laboratory for full analysis including the wet weights and dry weights of the samples. Provides a starting point for the generation of a nutrient balance between inputs (fertilisers) and outputs (harvested crop).
