Short comment on: 'nitrogen mineralisation in relation to previous crops and pastures' *.
September 1, 2007... Angus et al. (2006) published a paper from 2 field experiments conducted in southern New South Wales, where they determined net nitrogen (N) mineralisation in relation to previous crops and pastures. The comprehensive study was very interesting...

Reply to short comment * on: 'nitrogen mineralisation in relation to previous crops and pastures'.
September 1, 2007... In a recent paper we reported rapid nitrogen mineralisation in soil where lucerne and a mixture of the perennial grasses Phalaris aquatica and Dactylis glomerata had been growing (Angus et al. 2006). We were surprised that pastures containing...

A study of the interactions between salinity, soil erosion, and pollutant transport on three Queensland soils.(Report)
September 1, 2007... Introduction Salinisation of land and water resources is a major landscape degradation issue worldwide, with serious salt-related problems occurring in at least 75 countries (Rhoades 1990). In Australia in particular, 5.7 Mha of land is...

Burning crop residues under no-till in semi-arid land, Northern Spain--effects on soil organic matter, aggregation, and earthworm populations.(Report)
September 1, 2007... Introduction Stubble burning has traditionally been used in semi-arid land for pest and weed control and to facilitate soil management. In the study area of Central Navarre, north-east Spain (as in other Mediterranean regions), it is, or...

Effects of microbiotic crusts on evaporation from the revegetated area in a Chinese desert.(Report)
September 1, 2007... Introduction Microbiotic crusts are the dominant biological surface feature of arid and semi-arid landscapes (Eldridge and Greene 1994), and are viewed as being beneficial in maintaining soil stability (West 1990), nitrogen fixation...

Relationships between field texture and particle-size distribution in Australia and their implications.(Report)
September 1, 2007... I enjoy doing the soil-texture feel test with my fingers or kneading a clay soil, which is a short step from ceramics or sculpture. Hans Jenny (1984) Introduction Particle-size distributions (PSD) are compositions of...

Categorisation of soils based on potassium reserves and production systems: implications in K management.(Report)
September 1, 2007... Introduction Potassium supply to crop plants is a complex phenomenon involving relationships among various K fractions in soil. The dynamic equilibrium among these fractions directs the release of K from the nonexchangeable fraction, the...

Predicting the response of wheat (Triticum aestivum L.) to liquid and granular phosphorus fertilisers in Australian soils.(Report)
September 1, 2007... Introduction Comparing the effectiveness of liquid and granular phosphorus (P) fertilisers for crop production first occurred in the USA in the early 1970s, and showed that both fertiliser types were equally effective for plant production...

Copper release characteristics in selected soils from southern and northern Iran.(Report)
September 1, 2007... Introduction Copper (Cu) availability is low in uncontaminated soils, and deficiencies of this element have been reported in some soils (Lehman and Hatter 1984). In most agricultural soils, Cu availability is controlled by...

Effect of arsenate on adsorption of Zn(II) by three variable charge soils.(Report)
September 1, 2007... Introduction In terrestrial ecosystems, sorption-desorption reactions on soil colloid surfaces control the concentration of heavy metal in soil solution, and hence may affect their bioavailability, leaching, and toxicity (Backes et al....

Medicago ciliaris growing in Tunisian soils is preferentially nodulated by Sinorhizobium medicae.(Report)
September 1, 2007... Introduction Many species of the legume genus Medicago are native to the Mediterranean basin (Lesins and Lesins 1979) and are important as agricultural crops (Irwin et al. 2001). Compared to M. sativa, the most important species for...
