Date: 6. June 2025

Observation and photos of area before melioration (subsoiling):
• Sunny and dry, but some rain the previous night.
• Lots of wet spots /surface water after rainfall.

Date: 24. June 2025

Melioration (subsoiling) of 80% of the field:
• Machine: NHS NewAge T4 with compact roller
• Tractor: Case Puma 240
• Spear test before start: approx. 10cm
• Full improvement in longitudinal direction
• Standard working depth (approx. 55cm)
• Speed hampered by the size of the area – estimated approx. 4-6 km/h
• Test hindered by partly surrounding rapeseed and partly pile of gravel in the area.
• On the eastern long side, rubble and stones appear. Signs of filling.
• All spring bolts are intact after the work.
• Spear test after improvement: 30-50cm

Date: 29. June 2025

Observation:
• Only little rainfall since melioration – estimated 5-10mm
• The area is dry – all surface water is gone

Date: 15. July 2025

Observation:
• Regular cloudburst with 37 mm of water in 30 min.
• Observation 30 min. after cessation.
• The ground is soft without being swampy.
• The field is completely free of surface water

Date: 19. July 2025

Action:
• Rainwater meter installed on the test field
• EBH continuously monitors the field and reads precipitation.

Date: 25. July 2025

• We contact the landowner for an agreement on full melioration (tilling) of the field from end to end in an approx. 20 meter wide belt with test field 1 in the middle.
• The goal is to be able to demonstrate a difference – not just in a problem field, but also to show the difference in the crops when meliorated (tilled) area is compared to a non-tilled area.
• In practice, the difference will be an increased (deeper) cultivation layer in the meliorated field soil.
• In short, the plant's root system must be able to develop better and thus reach deeper into the cultivation layer
• Long-term difference must be read in the length of the plant roots, which will show the individual plant's ability to grow in dry periods.
• In short, the plant must develop better – reach further – set a better yield.
• The landowner gives full permission and also informs that the field must be sown with wheat immediately after harvest.
• Tests must be carried out after harvest / before sowing wheat

Date: 30. July 2025

Observation:
• After a day of thunderstorms and 10mm of rain, the field looks dry and well-balanced.

Date: 7. August 2025

Observation:
• 12 mm of water has fallen since the last measurement.
• The area looks healthy and satisfactory. Firm, but not dried out.
• Harvest is in progress around the area

Date: 11. August 2025

Observation:
• No water since last measurement (7. August)
• The area is clearly lush. Plenty of growth from previous sowings that have been revived. Among many other things, sunflowers are clearly visible.
