Influence of root exudates on soil microbial diversity and activity
(Lincoln University, 2009)
Interactions between plant roots and soil microorganisms in the rhizosphere are critical for plant growth. However, understanding of precisely how root exudates influence the diversity and activity of rhizosphere microorganisms ...
Noninvasive recovery and detection of possum Trichosurus vulpecula DNA from bitten bait interference devices (WaxTags)
The brushtail possum is a major agricultural and ecological pest in New Zealand. A novel noninvasive DNA sampling tool for detecting its presence (WaxTags, or WT) was tested. DNA was recovered from saliva left on WT, and ...
Critical evaluation of methods for determining total organic phosphorus in tropical soils
(Soil Science Society of America, 1990)
The determination of total organic phosphorus (TOP) in soils presents several methodological problems, particularly on strongly weathered and tropical soils. We reviewed the application of several methods for TOP determination ...
Phosphorus levels in topsoils under conifer plantations in Canterbury high country grasslands
(Lincoln University. Centre for Computing and Biometrics., 1996-09)
Topsoils under planted conifer forests in the Canterbury high country have high levels of 0.5 M H₂S0₄-P (inorganic P) compared to published records from topsoils of grasslands on soils of the same high country soil groups. ...
