Harvesting Complete

by Ed Tripp, University of Nottingham

All 514 seedlings have been harvested.

It took a good week or so to separate all the seedlings from the soil, dry them in an oven to remove the water, and then to weigh them.

It looks like the initial results are OK; there is some relationship between plant size and nitrogen deposition. However, there are still a great many factors that need to be included in the analysis which could explain the differences in plant size.


Soil sample month

by Ed Tripp, University of Nottingham

Two hundred and fifty-seven samples collected!

It took four weeks, and a good few thousand miles, but finally all the soil samples have been collected. These have now been placed in pots, and two heather seedlings are growing in each sample.

Currently the seedlings are less than 3mm high, but within the next six months they will grow slowly, to around 5cm!
