Start the farm record with its resources

Before selecting a service or technology, record the plot, water access, crop history and available equipment. This helps distinguish different causes of problems such as reduced yield.

For each operation, record the date, input quantity, time spent and observed result. Comparing periods is meaningful only when differences in weather, variety and methods are documented.

Define a limited objective, such as investigating water loss or recording harvesting costs. The desired result and its evaluation method should be clear from the start.
