Pencwm Project update November 2024
What has been done to date?
Visual examination of soil structure (VESS) was carried out with the below scores: -
- 0-10cm. Score 4 = poor. Little structure and very porous, this will hinder rooting, likely to be from cattle traffic.
- 10-15cm. Score 2. Good = well-structured soil with many pores and large round aggregates.
- 15-30cm. Score 1. Very good = Excellent structure, highly porous, good rooting conditions.
Yields (Table 1) for the different mixes were calculated using the cut and weigh methodology. This involved measuring an area of 1m x 1m, cut/pulled then weighed.
Table 1. Yield results.
| Yield (t/ha) | Yield (t/ac) | |
| Kale | 14.5 | 5.87 |
| Mix 1 | 9.5 | 3.85 |
| Mix 2 | 20.5 | 8.3 |
As seen in table 1, mix 2 (80% Forage Rye, 14% Winter Vetch, 2% Stubble Turnip, 2% Plantain and 2% Tillage Radish) was the highest yielding out of the three plots. Mix 1 (60% Tetraploid Italian ryegrass, 16% Spitfire Hybrid Brassica, 16% Crimson Clover and 8% Plantain) was the lowest yielding crop, producing shy of half the tonnage compared to mix 2.
Next steps:
- Cattle were introduced to graze the crops in October, their intakes will continue to be monitored.
- Electric fences are moved daily to help utilise crops and reduce wastage.
- Cleanliness of cattle and clearance of crops will be observed during the grazing period.
