Balancing the nitrogen (N) budgets of agricultural systems is essential for sustaining yields
at lower environmental costs. However, it is still rare to find reports on the total N budgets of …

Abstract Ammonium (NH 4+) has been reported as the preferred mineral N source (a
preference for NH 4+ uptake over NO 3-) for rice (Oryza sativa L.), the predominant supply of …

Nitrogen loss from cultivated soils threatens the economic and environmental sustainability
of agriculture. Nitrate (NO3−) derived from nitrification of nitrogen fertilizer and ammonified …

Nitrogen (N) fertilizer use efficiency (NUE) in flooded paddy fields is relatively low. Many N
fertilizer management options have been proposed to enhance NUE and minimize …

Elevated greenhouse gas (GHG) emissions, particularly of methane (CH 4) from flooded rice
production systems contribute to global warming. Different crop management strategies …

Purpose Although green manure rotation is often used to promote soil fertility and crop yield,
the effects of this management practice on the nitrogen or phosphorus balance and the …

Nitrification in the rhizosphere is a crucial process in controlling nitrogen‐use efficiency
(NUE) in flooded paddy soils. To understand the relationship between the nitrification ability …

Nitrate isotopes (δ 15 N-NO 3− and δ 18 O-NO 3−) are a potentially powerful tool for tracking
the biological removal of reactive nitrogen (N) as it is transported from land to sea. However …

Flooded paddy soil ecosystems in the tropics support the cultivation of the majority of the
world's leading crop, rice, and nitrogen (N) availability in the paddy-soil rooting zone limits …

Organic amendments not only improve soil conditions but also affect belowground biological
processes. This study used a split plot design to investigate the effects of cotton straw …
