The input to soils made by pollen and its subsequent mineralization has rarely been investigated from a soil microbiological point of view even though the small but significant quantities of C and N in pollen may make an important contribution to nut

Different earthworm species have different tolerances of acid soil conditions, and the application of lime to upland grassland to improve the grazing quality may therefore alter the size and diversity of the earthworm community. Altering soil propert

The leaf litter is the major source of soil organic matter in natural and many plantation crop ecosystems. Quantity and quality of organic matter in a soil ecosystem is of utmost importance in regulating the soil health. Hence assessment of quality o

The decomposition in soil of pieces of stem and different fractions of stems from uniformly-grown tobacco plants with genetic modifications to lignin biosynthesis was investigated by measuring CO2 production over 74 d. The fractions used were intact

Magnetic resonance imaging (MRI) provides a means of monitoring the change in position and the eventual breakdown of oil within sediments. The multidimensional technique allows the position of nuclei (most commonly protons) to be located within a kno

The biological health of soil is an important aspect of soil quality because of the many critical functions performed by organisms in soil. Various indicators of soil quality have been proposed, but measurements of microbial biomass are most commonly

A range of nuclear magnetic resonance (NMR) techniques, 1H liquid spectroscopy and T1 and T2 relaxation measurements, and microimaging, have been used to observe changes taking place within the bodies of live samples of Coccinella septempunctata, und

We investigated the effect of lime addition to an upland organic soil on the decomposition of Lolium perenne leaves and isolated fractions of L. perenne leaves in a laboratory experiment lasting 75 d. The L. perenne plants were grown in a 13 CO 2 -en
