Fluffgrass rhizosphere N mineralization potential

Nitrogen mineralization potential of soil rhizosphere of Erioneuron
pulchellum from Silva\'s dissertation research plots. Twenty 6 x 6 m
plots were established with a 3 m buffer between plots. Five plots were
randomly assigned to one of four treatments: (1) chlordane amendment
100ml AI (active ingredients) per 10,000 ml) to exclude microarthropods,
(2) sprinkler irrigation (6 mm per week), (3) sprinkler irrigation (6
mm/week) plus chlordate amendment (as above), (4) control (no treatment).
Three randomly located subsamples were taken from each plot
consisting of a fluff grass plant and a soil core 10 cm in diameter
and 15 cm deep centered on each plant. [taken from page 11 of
