Title:Effects of Chlordane and Water Amendments on Biomass and Total Nitrogen of Fluffgrass Plants on the Jornada LTER, 1986
Alternate Identifier:DOI PLACE HOLDER
Abstract:

This study hypothesized that changing densities of soil microarthropods would result in changes in nitrogen. In order to test this hypothesis, twenty 6 x 6 m plots were established with a 3 m buffer between plots. Five plots each 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). Dry weight biomass and total nitrogen were determined for flowers, green leaves and yellow and grey leaves of fluffgrass plants collected from plots. This study is complete.

Methods and protocols used in the collection of this data package
Description:

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 plants were collected from each plot. Plants were separated into flowers, green leaves and yellow/grey leaves. Shoot material was oven-dried for 96 hours at 50 C, weighed and ground in a Wiley Mill for chemical analysis. The ground plant was prepared for nitrogen analysis by a micro Kjeldahl digestion using an aluminum block. Nitrogen analyses were performed on the digest using automated procedures on a Scientific Instruments Continuous Flow Analyzer.
