The population abundance of free-living and plant-parasitic nematodes was investigated in a long-term rotation/tillage/stubble management experiment at Wagga Wagga Agricultural Institute, New South Wales (NSW), Australia. The treatments were a combin

A better understanding of tillage and stubble management effects on surface soil structure is vital for the development of effective soil conservation practices for the long-term. Relationships between aspects of soil structure and runoff/soil loss w

In Australia, stubble burning and tillage are two of the major processes responsible for the decline of soil organic carbon concentration in cropped soils, and the resulting soil degradation. However, the relative importance of these two practices in

Farm management practices have led to low soil organic carbon (SOC) and total nitrogen (TN) in Australia. Change in SOC and TN during 21 years of different rotation, tillage and stubble management systems were studied on a red earth, a Chromic Luviso

Farmers in south-eastern Australia have been advised, on one hand, to sow by direct drilling so as to conserve soil structure. On the other hand, farmers have been advised to thoroughly incorporate limestone into the soil so as to ameliorate acidity

Effect of 19 years of different tillage (direct drilled vs. conventional tillage) and stubble management (stubble retained vs. burnt) on soil carbon fractions were studied in a red earth, an Oxic Paleustalf at Wagga Wagga, NSW. The changes in carbon

A long-term field experiment commenced in 1979 at Wagga Wagga, NSW, Australia, to study the sustainability of a range of rotation, tillage and stubble management systems on a red earth. This paper presents results on lupin growth and grain yield in r

Significant differences in soil structure and soil physical properties were detected on a red earth (Oxic Paleustalf) which had grown four different winter crops in rotation with wheat in Wagga Wagga, N.S.W., Australia. At the end of the fourth seaso

Lupin, field pea, lentil, chickpea, canola, linseed, and barley were sown at different times (late April-early July) to study their effects on subsequent wheat production on a red earth at Wagga Wagga, New South Wales. The cultivars of field pea (Pis

The decline in topsoil (0–0.1 m) pH (CaCl2) over 11 years (1979–90) was measured in a rotation, tillage, stubble and nitrogen fertilizer experiment on a Chromic Luvisol at Wagga Wagga in S.E. Australia. The rotations consisted of annual wheat cro
