    Evaluation of soil tests for predicting pasture response on acid soils to phosphate supplied in water soluble and sparingly soluble forms

    A range of soil tests, (moderately alkaline extractions of Olsen and Colwell, acid extractions of Truog and Bray and an anion exchange resin, with and without a cation exchange resin) were assessed for their a...

    Liming effect of reactive phosphate rocks: A laboratory evaluation

    A laboratory incubation study evaluated the liming properties of North Carolina (NC) and Arad phosphate rocks (PRs). Application of these two reactive phosphate rocks (RPRs) to topsoil samples of a Typic Albaq...

    Elevated CO2 effects on carbon and nitrogen cycling in grass/clover turves of a Psammaquent soil

    Effects of elevated CO2 (525 and 700 μL L−1), and a control (350 μL L−1 CO2), on biochemical properties of a Mollic Psammaquent soil in a well-established pasture of C3 and C4 grasses and clover were investigated...

    Partitioning and translocation of photosynthetically fixed 14C in grazed hill pastures

    Information on carbon (C) flows and transformations in the rhizosphere is vital for understanding soil organic matter dynamics and modelling its turnover. We followed the translocation of photosynthetically f...

    Carbon and phosphorus transformations during decomposition of pine forest floor with different phosphorus status

    Information on the mineralization of inorganic phosphate (Pi) from organically bound P (Po) during decomposition of forest floor and soil organic matter is vital for understanding P supply in forest ecosystems. ...

    Changes in soil microbial biomass, metabolic quotient, and organic matter turnover under Hieracium (H. pilosella L.)

     In New Zealand Hieracium is an opportunistic plant that invades high country sites more or less depleted of indigenous vegetation. To understand the invasive nature of this weed we assessed the changes in soil C...

    Soil organic matter transformations induced by Hieracium pilosella L. in tussock grassland of New Zealand

     To study the effect of Hieracium pilosella L. invasion on the transformations of soil organic matter of New Zealand tussock grassland soils (Ustochrepts), plant material and soils underneath Hieracium, the surro...

    Influence of soil phosphorus status and nitrogen addition on carbon mineralization from 14C-labelled glucose in pasture soils

     This study examines the effect of soil P status and N addition on the decomposition of 14C-labelled glucose to assess the consequences of reduced fertilizer inputs on the functioning of pastoral systems. A contr...

    Estimating seasonal and annual carbon inputs, and root decomposition rates in a temperate pasture following field 14C pulse-labelling

    Using a 14C pulse-labelling technique, we studied the seasonal changes in assimilation and partitioning of photoassimilated C in the plant–root–soil components of a temperate pasture. Pasture and soil samples wer...
