Week 49 - Bed DD7
We finally cleared the old pea plants out of this bed and failed to find any nitrogen fixing nodules on the roots. It is possible that any nodules that formed had fallen off when the plants died, but we suspect that the specific bacteria that form these beneficial nodules are not in this soil. This field contains many clover plants which have the nodules, but it is a different but species which forms the symbiotic relationship with plants from the bean and pea family.
This absence would make sense, given that peas and beans probably have not been grown in this field for many decades. The lack of this extra source of nitrogen probably reduced the yield of the peas. We will have investigate how to inoculate the soil before the next sowing of peas and beans.

We cultivated this bed to remove the few struggling seedlings and weeds and sowed two long rows of:
- Aquadulce Claudia Broad Beans (two double staggered rows, 48 seeds) - an excellent autumn sowing variety which establishes itself very quickly and will produce a very early crop. It is white seeded with pods up to 23 cm long.
Week 49 - Bed DD1
We finally double dug this bed and cleared the section to the west (left side of photo) of grass which we added as fertility on top of the lower level that we loosened. We added a few buckets of well rotted horse manure, and this bed is not ready for planting, though we should add some more compost or other source of fertility in the spring.
Week 49 - Bed EX8
We finally cleared out the remains of the peas and broad beans, and as with elsewhere in the plots, there were not any nitrogen fixing nodules. It seems that the specific beneficial bacteria that form these symbiotic nodules on the roots of the peas and beans is not present in the soil of this field. This would make sense given that peas and beans have not been grown in this field for decades.
The poor yield peas and beans is probably due to this lack of additional nitrogen. We will have to find a way of introducing these bacteria to the soil before we plant any more peas.

Week 49 - Bed EX7
We finally pulled out the remains of the peas and broad beans at the far end of the bed and found that there were no nitrogen fixing nodules. This was the same with other plots and it seems that this does not have any of the bacteria species particular to the pea andbean family of plants. This absence would make sense, given that peas and beans probably have not been grown in this field for many decades. The lack of this extra source of nitrogen probably reduced the yield of the peas. We will have investigate how to inoculate the soil before the next sowing of peas and beans.
The ryegrass that we sowed as a cover crop is doing well, at least in the area that had been empty, but there is still no sign of clover or vetch.
