Effects of Nitrogen Nutrition on Accumulation and Speciation of Sulfur Compounds in Garlic Under Field Conditions

Binh T. Nguyen, J. Bernhard Wehr, Peter M. Kopittke, Timothy J. O’Hare et autres

Nitrogen (N) supply can influence the accumulation of sulfur (S)-containing metabolites that contribute to garlic (Allium sativum L.) flavour and quality, yet evidence of these responses under field conditions remains limited. Nine N application rates (0–360 kg ha−1) were evaluated under field …

A comparative study of methods to quantify wheat yield penalty attributable to soil sodicity across north-eastern Australia

Yunru Lai, M. Pringle, Peter M. Kopittke, Neal W. Menzies et autres

Soil sodicity is a major limitation to wheat production in Australia, yet estimating its yield impact remains challenging due to interactions with climate, management, co-occurring soil constraints, and heterogeneous data support. This study compares three approaches for quantifying and mapping yield penalties …

On-farm soil organic carbon dynamics under conservation agriculture in different cropping systems of eastern Gangetic alluvial soils

S. Rakesh, Abhas Kumar Sinha, Mahesh K. Gathala, Neal W. Menzies et autres

and no-till practices sequester soil carbon (C) and improve soil texture. Little detailed information is available quantifying the effects of these practices in rice-based cropping systems on the alluvial soils which are widely found across key rice-cultivating regions of South and Southeast …

Effects of Nitrogen Application Rate on Bulb Yield, Nitrogen Use Efficiency, and Normalised Difference Red Edge-Based Nitrogen Diagnostics in Garlic Varieties

Binh T. Nguyen, J. Bernhard Wehr, T.J. O’Hare, Neal W. Menzies et autres

Optimising nitrogen (N) management is crucial for improving garlic (Allium sativum L.) productivity and nitrogen use efficiency (NUE). This study evaluated the effects of N application rate on bulb yield, NUE, and the links between N status, Normalised Difference Eed Edge (NDRE), …

Rubber plantation management affects soil nitrogen availability and tree growth in smallholder farms: Evidence from a survey in Agusan del Sur, southern Philippines

Oscar Jurado, Johnvie Goloran, Adeflor Garcia, Xiangyu Liu et autres

Natural rubber (NR) is a critical industrial commodity, and its production in Southeast Asia is dominated by smallholder farmers. In the Philippines, rubber farming is a major source of income for rural communities. However, the link between field management, soil properties and …

Comparison of plant response and phosphorus uptake by ion exchange desorption and chemical extraction for soils under different land uses

Yaqi Zhang, Dingjiang Chen, Lizhong Zhu, Wenxiang Zhou et autres

Abstract Aims We quantified the relative significance of phosphorus (P) availability quantity and rate of P desorbed to plant growth using ion exchange membranes on three soils (0–10 cm), initially under native vegetation and converted to either cropping, pasture, or plantation for …

Soil is a major contributor to global greenhouse gas emissions and climate change

Peter M. Kopittke, Ram C. Dalal, Brigid A. McKenna, Pete Smith et autres

It is unequivocal that human activities have increased emissions of greenhouse gases, that this is causing warming, and that these changes will be irreversible for centuries to millennia. Whilst previous studies have broadly examined the contribution of agriculture or land use change …

Irrigation of rangeland soils with coal seam water - A lysimeter study on soil physico-chemical properties

J. Bernhard Wehr, Scott A. Dalzell, David C. Macfarlane, Neal W. Menzies et autres

Groundwater extracted from coal seams may be a resource for irrigation of land in areas with low rainfall, but the effect of this water on soil properties needs to be established. A lysimeter study was conducted using intact soil cores (0.75 m …
