9 Improved grading out of furrow (wings) Paired rows - 50% more seeding row High press wheel pressure - firming Good seed/fertiliser separation Knife points Winged & paired rows

10 Knife points Stilletto boots

11 Lure H2O trials on non- wetting soils of the West Midlands region NAMI funding partners: Purpose: To investigate the influence of rate, application timing and soil type of the activity of Lure H20 as a pre- sow soil wetting agent in the cropping phase Product rate/ha: 10 L 20L 40L Timings: 16 th March 14 th April

12 Soils Yellow deep sandShallow sandy gravel Shallow loamy gravel

13 Loamy gravel results Soil moisture 40L March- 15% average soil moisture content Control- 13% average soil moisture content

14 Loamy gravel results Crop emergence Plants per meter row March 20L, March 40L and April 40L were significantly different to untreated control.

15 Loamy gravel results Biomass Green leaf/ biomass assessment NDVI March 20L, March 40L and April 40L were significantly different to untreated control. Untreated controlMarch 20LMarch 40L
