What the sky and soil are doing, in plain language
Erosion on bare sloping ground
Zones 1 and 2 have the steepest slopes. Heavy storms on uncovered soil can remove topsoil quickly.
Rain and water supply: falling
Rain has been tapering off over the last weeks, with most of it falling in two heavy events.
Soil moisture: falling
The top few centimetres are drying out steadily. Deeper soil usually stays wetter than this.
Heat and sunlight: rising
Days are warming gradually as the rains ease. Sunlight is strong and steady.
Crop greenness: falling
Greenness peaked and is now easing, which is normal as maize approaches maturity.

What to do: Plan for drier weeks ahead. Mulch to hold the moisture you still have.

What to do: Check soil with your hand at 30 cm before deciding to irrigate or delay planting.

Days are warming gradually as the rains ease. Sunlight is strong and steady.
What to do: Plant short-cycle varieties earlier in the next season window to avoid late heat.

Fortnightly greenness, oldest to newest
Greenness peaked and is now easing, which is normal as maize approaches maturity.
What to do: Compare this curve between rotation options to see which keeps cover longest.

Recent passes, oldest to newest
Plants are running warmer than the air, an early sign they may be short of water.
What to do: Prioritise zones with the highest stress for scouting and mulching.
Source: NASA ECOSTRESS (planned source)
High confidence.Passes are irregular and depend on the orbit. Few observations means wider uncertainty.

Slope across the five schematic zones
Moderate slopes mean heavy storms can wash topsoil downhill, especially on bare ground.
What to do: Keep soil covered on the steepest zones. See the erosion view for the risk breakdown.
