It&#39;s that time again, four years have passed since last soil analysis. At least 25 samples into a clean bucket from a &#39;W&#39; shaped path across plot, from top 15cm, surface soil scraped away first, mixed well and a kilo bagged to send to lab.  @graciebarrett01 #allotment #soil<br>http://pic.twitter.com/Q64ZiAJ3CU
