Assessment of the seed stock in a cultivated soil



Assessment of the seed stock in a cultivated soil



Comptes Rendus de la 13e Conference du COLUMA (Tome 1): 25-36



Weed seeds in 300 soil samples were identified, counted and their distribution assessed. Curves were calculated to determine the sampling error in relation to the number of soil samples, variance and av. seed numbers/sample. The strong relationship between the variance and av. seed populations enabled the sampling error to be determined as a function of the number of soil samples and the av. number of seeds/sample.
