SR21089Long-term dairy manure application in a no-tillage system: crop yield and soil fertility

Gabriel Barth, Lenir Fátima Gotz 0000-0001-6145-4717, Nerilde Favaretto and Volnei Pauletti
pp. 1-10

In rotation system with annual crops, maize and black oat showed greater response to annual manure application, in addition to mineral fertilisation, with maximum yield for a dose of 150 m3 ha−1 year−1. Although it was applied to the soil surface, the manure provided chemical improvements in deep layers. The increase in yield with manure application was attributed to improved soil acidity attributes and the effect on nutrient availability.

SR20237Yield-scaled greenhouse gas emissions from the use of common urea and controlled-release nitrogen fertiliser in a subtropical paddy rice field

Thais Antolini Veçozzi 0000-0001-5100-2290, Rogério Oliveira de Sousa 0000-0001-9857-5766, Walkyria Bueno Scivittaro, Cimelio Bayer 0000-0001-8553-7330, Anderson Dias Silveira and Thaís Murias Jardim
pp. 11-21

Fertiliser use contributes to climate change, but is essential to agriculture. We evaluated an alternative nitrogen (N) fertiliser to make paddy rice more sustainable. N fertiliser applied at time of rice sowing had no effect on N2O emissions, but increased CH4 emissions except when controlled-released N fertiliser was applied. Rice yields were not affected by N sources.

SR21013Storage of soil samples leads to over-representation of the contribution of nitrate to plant-available nitrogen

Taleta Bailey 0000-0001-8389-0827, Nicole Robinson, Mark Farrell 0000-0003-4562-2738, Ben Macdonald 0000-0001-8105-0779, Tim Weaver, Diogenes L. Antille, Aidan Chin and Richard Brackin 0000-0002-6899-5935
pp. 22-32

Soil sampling and storage conditions influence measurements of plant-available nitrogen (N) pools, including nitrate, ammonium and dissolved organic N. This study compares a non-disruptive soil sampling technique (microdialysis) to traditional soil extracts, and shows that delaying soil sample processing can greatly over-estimate soil nitrate levels, even when preservation techniques like refrigeration are used. This has implications for interpreting both agronomic soil tests for fertiliser recommendations and soil N analyses for research.

SR21021Crop yields in no-tillage are severely limited by low availability of P and high acidity of the soil in depth

Roque Junior Sartori Bellinaso, Tales Tiecher, Jocelina Paranhos Rosa de Vargas 0000-0003-0477-5834 and Danilo Santos Rheinheimer
pp. 33-49

The demand for food increases every year, so increasing crop yields is an important issue. The aim of this study was to evaluate the changes in soil chemical properties and response of crop yields to different application methods of lime and phosphate fertiliser. The results show that with the correction of soil acidity and the availability of phosphorus in depth was possible to increase soybean productivity by more than 40%. Studies like these are important for better productivity worldwide.


Organic matter is an important soil component, and the organic debris aboveground is the main organic matter source in forest soils. However, how debris decomposition rates influence transfers by leaching of organic matter into the soil is not fully understood, and our results indicate that there is no linear relationship between higher or lower decomposition rates and greater or lesser transfers by water. We found a comparatively intermediate decomposition releasing more organic matter into the soil.

SR21020Carbon and nitrogen in particle-size fractions of organic matter of soils fertilised with surface and injected applications of pig slurry

Cremildo António Luís Francisco, Arcângelo Loss 0000-0002-3005-6158, Gustavo Brunetto, Rogério Gonzatto, Sandro José Giacomini, Celso Aita, Marisa de Cássia Piccolo, José Luiz Rodrigues Torres 0000-0003-4211-4340, Carina Marchezan, Gustavo Scopel and Ricardo Fagan Vidal
pp. 65-72

Injection of pig slurry in conservationist management systems, such as no-tillage, can increase soil organic matter. Use of injected application of pig slurry to soil results in lower carbon and nitrogen losses by volatilisation and emissions to the atmosphere than surface applications of pig slurry. Application of pig slurry to soils under a crop rotation with maize, oat, and wheat under no-tillage, using injection of pig slurry in soil, promotes higher increases in contents of soil organic matter.

SR20305Structural and hydraulic responses of humid tropical soils to lime and organic residue amendments

Ronen Francis 0000-0002-6422-3225, De Shorn E. Bramble 0000-0002-1212-4575, Mark N. Wuddivira and Gregory A. Gouveia
pp. 73-85

The management of humid tropical soils utilising organic residues and lime is critical for food security in the Caribbean. Our investigations uncovered the positive effects of lime additions on water movement through soils as well as its short-term negative effects on stability and soil water repellency at different soil moisture levels. This research highlights the importance of understanding the combinational effects of amending humid tropical soils with lime and organic residues of different qualities.

SR20264Soil moisture impacts nitrification from nitrogen fertilisers treated with 3,4-dimethylpyrazole phosphate in acidic soils

Brooke Kaveney 0000-0001-8132-8961, Jason Condon 0000-0001-8300-0927, Gregory Doran, Francesca Galea and Jessica Rigg
pp. 86-101

Rotational farming is common in Australian broad acre farming regions and can induce changes in soil properties that effects microbial nitrifying populations. This study investigated the effects of soil properties on the efficacy of the nitrification inhibitor 3,4-dimethylpyrazole phosphate (DMPP) and found that inhibition was more effective in neutral soils, with decreasing efficacy as soil acidity increased. Application of nitrogen fertilisers in conjunction with moisture onto dry soils enhanced nitrification rates.
