Yield and nitrogen use efficiency of wheat increased with root length and biomass due to nitrogen, phosphorus, and potassium interactions

Autor: Kelley Whisson, Jairo A. Palta, Mark B. Peoples, Elliott G. Duncan, Margaret M. Roper, Cathryn A. O’Sullivan

Publikováno v: Journal of Plant Nutrition and Soil Science. 181:364-373

Balanced applications of nitrogen (N), phosphorus (P), and potassium (K) are known to increase grain yield of wheat but the impact of the interactions among N, P, and K on root growth and nitrogen use efficiency (NUE) have not been proven. The aim of

Publikováno v: Plant and Soil. 413:275-287

A simple, rapid, colourimetric method for screening biological nitrification inhibitors in plants is presented. Our approach combines the use of the Griess assay to track the rate of nitrite (NO2 −) production by pure cultures of ammonia oxidising

Crop and microbial responses to the nitrification inhibitor 3,4-dimethylpyrazole phosphate (DMPP) in Mediterranean wheat-cropping systems

Autor: Margaret M. Roper, Elliott G. Duncan, Cathryn A. O’Sullivan, Mark B. Peoples, Kelley Whisson, Karen Treble

Nitrification inhibitors (NIs) such as 3,4,-dimethylpyrazole phosphate (DMPP), are used to suppress the abundance of ammonia-oxidising micro-organisms responsible for nitrification. In agriculture, NIs are used to retain soil mineral nitrogen (N) as

The nitrification inhibitor 3,4,-dimethylpyrazole phosphate strongly inhibits nitrification in coarse-grained soils containing a low abundance of nitrifying microbiota

Autor: Cathryn A. O’Sullivan, Anna K. Simonsen, Kelley Whisson, Mark B. Peoples, Elliott G. Duncan, Karen Treble, Margaret M. Roper

The effectiveness of the nitrification inhibitor 3,4,-dimethylpyrazole phosphate (DMPP) on sandy soils containing low nitrifying microbial abundance has not been established. Two coarse-grained soils, representative of Western Australia's agricultura

A composite guanyl thiourea (GTU), dicyandiamide (DCD) inhibitor improves the efficacy of nitrification inhibition in soil

Autor: Margaret M. Roper, Kelley Whisson, Elliott G. Duncan, Anna K. Simonsen, Cathryn A. O’Sullivan, Karen Treble

Publikováno v: Chemosphere. 163

This study investigated whether applying dicyandiamide (DCD) and guanyl thiourea (GTU) in conjunction with urea improves the efficacy of nitrification inhibition relative to traditional fertiliser application of urea or urea + DCD. Urea at a rate of

Biological nitrification inhibition by weeds: wild radish, brome grass, wild oats and annual ryegrass decrease nitrification rates in their rhizospheres

Autor: P. R. Ward, Cathryn A. O’ Sullivan, Kelley Whisson, S. F. Micin, Karen Treble, Margaret M. Roper

Publikováno v: Crop and Pasture Science. 68:798

This study investigated the ability of several plant species commonly occurring as weeds in Australian cropping systems to produce root exudates that inhibit nitrification via biological nitrification inhibition (BNI). Seedlings of wild radish (Rapha

The impact of wheat stubble on evaporation from a sandy soil

Autor: D. Zeelenberg, P. R. Ward, S. F. Micin, Kelley Whisson, Stephen P. Milroy

Publikováno v: Crop and Pasture Science. 60:730

In Mediterranean-type climates, dryland soil water storage and evaporation during the hot and dry summer are poorly understood, particularly for sandy-textured soils. Continued evaporation during summer, and any effects of crop stubble management, co

Water use by annual crops. 1. Role of dry matter production

Autor: Kelley Whisson, S.F. Micin, P. R. Ward, D. Tennant, D.J.M. Hall, T..M. Willis, Karen Treble

Publikováno v: Australian Journal of Agricultural Research. 58:1159

In southern Australia, expanding dryland salinity is the result of increased deep drainage associated with widespread replacement of native perennial vegetation by annual agricultural crops and pastures. Although perennial pastures have been shown to
