AgriWebb's Stocking Rate vs Carrying Capacity Report (SR:CC) enables you to look back historically, using cumulative stocking rate (in stock days or DSE days per ha and rainfall records).
Compare against your own farm benchmark or long-term sustainable carrying capacity to see when you have been overstocked or understocked to plan ahead accordingly.
Setting Up & Navigating the Report
To access the Stocking Rate vs Carrying Capacity report, you'll need to be subscribed to Performance on either Mob or Individual Animal Management (IAM) plans. Visit the Web App and navigate to Grazing > Stocking Rate vs Carrying Capacity to get started.
You’ll need 3 things to get started:
Stocking rate data (this you will already have, but if you have just started using AgriWebb you may not have full historical data yet)
Rainfall data
Benchmark carrying capacity
1. Stocking rate data
This will populate automatically based on your livestock stocking rate.
2. Rainfall
Firstly, select your preferred rain gauge to use for your rolling rainfall in the top right. Don’t have a rain gauge? Here is how you can add them.
3. Benchmark
At the top of the report you'll see your key stats.
Average Stocking Rate = avg. for the date range selected (we default to rolling 12 months)
Average Capacity Gap = this is the average stocking load you were under or overstocked during the period selected. This value will populate once a benchmark value has been added.
Benchmark carrying capacity = add this to use as a comparison and tracking when you are overstocked.
To do this select +Add and choose the relevant date. If you need to update a historical benchmark, add a new benchmark with the same date and it will replace the existing benchmark.
Not sure what your benchmark/long-term sustainable carrying capacity is?
Think about how many DSE or LSU you usually run and your avg rainfall.
For example Long term we run 1 LSU per 4 ha and average rainfall of 600mm for 365 days
I.e. 1 LSU x 365 days per 4 ha per 600mm
Stock days = 1 x 365 days = 365 stock days per 4ha per 600mm
SDH = 365/4 = 91.25 per 600mm
SDH/100mm = 91.25/600mm /100mm = 15.2 SDH/100mm

Stocking Rate vs Benchmark Carrying Capacity Graph
The graph will be populated based on the monthly data seen in the table below the graph. On the left axis you'll see the Cumulative stocking rate (rolling 12 months) and on the right axis rainfall.
Green line = Benchmark carrying capacity. You can add new benchmarks over time and these changes in benchmark will be reflected on the chart..
Black line = The stocking rate (in SDH/100mm or DDH/100mm) will show as the black line when on target or understocked against the benchmark.
Red line and area = Indicates when stocking rate is overstocked against the benchmark.
Blue line = The rolling rainfall
Monthly Data (Table)
Below the graph you'll see a breakdown of monthly data. This can help you identify any gaps in your AgriWebb data and better understand the calculations.
How to Interpret the Report
Overstocked
When you're overstocked the average capacity gap will present as red and as a positive number, this is also reflected on the graph with the area between the benchmark and stocking rate. This means that for that period of time you've got more stock than the land can carry (based on your benchmark). This may help you decide to de-stock/sell stock based on the difference (the stock days capacity gap) to meet the carrying capacity of your land.
In example above, the farm was overstocked mid Jul til early Oct.
Understocked
When you're understocked the average capacity gap will show as a black negative number. It will also say 'Understocked'. In the graph this will present as a black line. This means that for that period of time you've got less stock than what the land can comfortably carry (based on your allocated benchmark). This may help you decide to buy/agist stock based on the difference (the stock days capacity gap) to efficiently meet the carrying capacity of your land.
In example above, the farm was understocked or on target with the benchmark for most of year, with the exception of the period of time between mid Jul til early Oct.
Key Calculations
Stock Days: The number of DSE, LSU, AU or AE days grazed across the property. e.g. 100 DSE grazing for 10 days is 1000 DSE days.
Stock Days / ha / 100mm or inch of rainfall: The report shows cumulative stock days/ha/100mm using 12 month rolling data. e.g. the monthly value for April is:
12 month rolling stock days (May-April)
/ grazeable area on farm
/ 12 month rolling rainfall (May-April)
/ 100 (if using mm for rainfall, other just per inch)
Capacity Gap: The avg. animal units (stocking load) you were over or under the benchmark for the reporting period. This gives you an understanding of how many animal units (DSE/LSU etc.) you were over or under by.
Actual (Stock Days / ha / 100mm) vs benchmark: The % difference between your actual stocking rate vs the benchmark carrying capacity of your farm for the month or reporting period.
FAQs
Question | Answer |
Which plans have access to this report? | All Performance plans globally. |
What info do I need to use the SR:CC report? | Rainfall, stocking (movement) records and a benchmark for your property. |
Can I use this SR:CC report if I run multiple blocks? | Yes, but it will be at a property (AgriWebb farm) level. We do not currently breakdown by block. |
Can I view this on the App? | This report tool is only available on the web in the grazing tab. |
I manage my grazing on a kg DM/ha basis, how does the report work for my property? | This is a stocking rate focused report so we will use the units you have on farm (SDH/DDH or kg DM/ha) x days grazed / grazeable area. The carrying capacity is currently a benchmark for the average stocking rate you can carry on farm, standardised with the rolling rainfall to account for seasonal variability. |
