Title:	Effects of Chlordane and Water Amendments on Fluffgrass Plant Nutrient Content on the Jornada Basin LTER, 1986-1987
Alternate Identifier:	DOI PLACE HOLDER
Abstract:	Recent studies suggest that rhizosphere soil microarthropods may have a major role in determining soil nitrogen availability. Desert soil microarthropods are consumers of soil bacteria, fungi, and nematodes, thus they accelerate mineralization processes by causing turnover in immobilized nitrogen.. 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 soil subsamples were taken from each plot. For each sample a plant was measured (two diameters and one height) then clipped at ground level, collected in a paper bag and transported the lab. After a plant was collected, a rhizosphere soil sample was taken using a soil core (10 cm diameter, 15 cm depth). The soil sample was placed in a plastic bag, stored in a cooler and immediately transported to the lab (see package 210385001). This dataset contains plant diameters, mites soil weight, root weight, nematode soil weight, root total nitrogen, and nematode number. See methods for detailed information. For additional data from this larger study, refer to other JRN packages: 210385004, 210385003, 210385008, 210385005, 210385006, 210385001. Sampling occurred in 1987. This study is complete.

Description:

For each sample a plant was measured (two diameters and one height) then clipped at ground level, collected in a paper bag and transported the lab. After a plant was collected, a rhizosphere soil sample was taken using a soil core (10 cm diameter, 15 cm depth). The soil sample was placed in a plastic bag, stored in a cooler and immediately transported to the lab (see package 210385001). Roots were separated from the soil using a 2 mm sieve, picked up from debris with forceps and cleaned up by hand. Roots were stored in envelopes, oven-dried for 96 hours at 50 C, weighed and ground in a Wiley Mill for total nitrogen analysis. The ground roots were prepared for N analysis by a micro Kjeldahl digestion using an aluminum block digestor (Keeney and Nelson 1982). Nitrogen analyses were performed on the digest using automated procedures on a Scientific Instruments Continuous Flow Analyzer. For each soil sample, subsamples were taken for extraction of microarthropods and nematodes. Microarthropods were extracted in modified Tullgren funnels into water (Santos et al. 1978), then counted and identified to species (Krantz 1978). After microarthropod extraction the soil was sieved through a 2-mm screen mesh and roots were collected. On subsamples for nematode extraction, roots were carefully separated by hand, then nematodes were extracted by a modified sugar flotation technique (Freckman et al. 1977). Remaining soil was sieved through 2-mm screen mesh, then roots were collected and added to roots collected from other subsamples.
