Pick the plot first Open a new chat and tap Plots (All) under the question box. Choose the plot you want advice for. ORTH then works from that plot’s crop, variety, soil and documents, and from the farm weather. For blueberry Pick one plot of one variety. We picked Arándanos: Ventura southern highbush blueberry on 1.82 ha under macrotunnel, about 6,000 plants planted in January 2023, sandy soil and drip. Every number below is for that plot. - 2
Start from the Irrigation button Pick the plot and tap Irrigation. ORTH offers questions such as this week’s schedule, a water-quality check, or turning the water requirement into runtime for your system. Tap one to ask it. For blueberry Under a macrotunnel, the cover decides how much rain reaches the root zone. Tell ORTH if it does, and it adjusts the schedule. - 3
This week’s water, before the rain We tapped Build this week’s irrigation schedule for this plot. ORTH treated Ventura as post-harvest with low uptake and proposed two maintenance irrigations before the rain: 2.3 mm on Thursday and 2.2 mm on Saturday, 4.5 mm in all, 81.9 m³ for the plot or 13.64 litres per plant. From Sunday it holds, unless the cover keeps the rain from the drip zone. It asked for the emitter flow before giving minutes, and rated it three stars. - 4
From litres to minutes We told ORTH each plant has two 1.6 L/h drippers. At 3.2 L/h per plant it gave 131 minutes on 5 November and 125 minutes on 7 November, 256 minutes for the week, with a check on 8 November to hold if the root zone is wet. The formula: litres per plant divided by 3.2, times 60. - 5
Save the proposal as actions When ORTH proposes a plan, tap Review to see every action with its date, category and instructions. Change or add actions if you need to, then tap Create. The actions land in the plot’s plans, ready to assign to someone on your team. For blueberry On Arándanos this saved the weekly irrigation plan with three actions, from 5 to 8 November. - 6
What changes in coir pots We asked what would change in 40 L coir pots. ORTH turned two long irrigations into two or three short pulses a day, from morning to early afternoon, aiming for 10 to 15% drainage over the whole day. With the same water, that is about 292 minutes for the week instead of 256. Measure what goes in and what drains from a few pots after the first day.
