“…One potential approach is to monitor nutrient concentrations in the field ponding water. Liu et al [19] found that concentrations of both total phosphorus and dissolved reactive phosphorus in surface runoff were significantly correlated with their concentrations in the field ponding water (r 2 = 0.83-0.88, p < 0.0001). In a follow-up study, Hua et al [27] monitored different forms of phosphorus concentrations in field ponding water of five paddy soils over 2 years.…”

“…Phosphorus and nitrogen applied to paddies with fertilizers and manures contribute to both short-term and long-term nutrient losses to the water environments. In a 3-year field study on the hydromorphic paddy soil, for example, Liu et al [19] found that annual total phosphorus loss in surface runoff ranged from 0.63 kg/ha in the unfertilized rice-wheat rotation to 0.96-2.86 kg/ha when rice and wheat were fertilized with 50-230 kg phosphorus per hectare. In the same study, they found relatively smaller total phosphorus losses from the Table 3.…”

“…Although the differences in magnitude of phosphorus losses in the two soils could result from different soil characteristics and rainfall patterns, both revealed increased phosphorus losses with greater phosphorus fertilizer application rates ( Table 3). Furthermore, Liu et al [19] found that the time interval between fertilizer application and the subsequent first large runoff event played a critical role in determining the annual phosphorus losses. Phosphorus losses greatly increased with decreasing time interval.…”

“…In China, the approach for monitoring water quality in paddy systems has become standardized over the past 2 decades [12,19,29]. In the field, research plots are separated with plastic films down to 0.9 m in the soil profile and with soil berms up to 0.2 m on the soil surface to prevent flow of surface and shallow subsurface water between the plots ( Figure 6).…”

Irrigated paddy rice (Oryza sativa L.) is a staple food for roughly half of the world'spopulation. Concerns over water quality have arisen in recent decades, particularly in China, which is the largest rice-producing country in the world and has the most intensive use of nutrients and water in rice production. On the one hand, the poor water quality has constrained the use of water for irrigation to paddy systems in many areas of the world. On the other hand, nutrient losses from paddy production systems contribute to contamination and eutrophication of freshwater bodies. Here, we review rice production, water requirement, water quality issues, and management options to minimize nutrient losses from paddy systems. We conclude that management of nutrient source, rate, timing, and placement should be combined with the management of irrigation and drainage water to reduce nitrogen and phosphorus losses from paddies. More research is needed to identify cost-effective monitoring approaches and mitigation options, and relevant extension and policy should be enforced to achieve water quality goals. The review is preliminarily based on China's scenario, but it would also provide valuable information for other rice-producing countries.

Fertilization as the most critical factor affecting yield response and agronomic efficiency of phosphorus in Chinese rice production: evidence from multi‐location field trials

et al. 2023

BACKGROUNDEfficient utilization of phosphorus (P) has been a major challenge for sustainable agriculture. However, the responses of fertilizer rate, region, soil properties, cropping systems and genotypes to P have not been investigated comprehensively and systematically.RESULTSA comprehensive analysis of 9863 fertilizer‐P experiments on rice cultivation in China showed that rice yield increased first and then fell down with the addition of P fertilizer, and the highest yield of 7963 kg ha−1 was observed under 100% P treatment. Under 100% P treatment, the yield response of applied P (YRP) and agronomic efficiency of applied P (AEP) were 12.8% and 30.1 kg ha−1, respectively. Lower soil pH (< 5.5) and organic matter (< 30.0 g kg−1) were associated with lower YRP and AEP. By contrast, soil available P < 25.0 mg kg−1 resulted in decreased YRP (15.3 to 11.4%) and AEP (32.3 kg kg−1 to 26.2 kg kg−1), whereas soil available P > 25.0 mg kg−1 maintained the relatively stable YRP and AEP. Also, the YRP and AEP were significantly higher for single‐cropping rice compared to other cropping systems. Moreover, the rice genotypes such as ‘Longdun’, ‘Kendao’ and ‘Jigeng’ had higher YRP and AEP than the average value. Overall, the fertilizer‐P rate was the primary factor affecting YRP and AEP, and the recommended P fertilizer rate can be reduced by 9–21 kg P ha−1 compared to existing expert recommendations.CONCLUSIONThe present study highlights the role of fertilizer‐P rate in maximizing the YRP and AEP, thereby providing a strong basis for future fertilizer management in rice cultivation systems. © 2023 Society of Chemical Industry.

IntroductionNitrogen use efficiency (NUE) is lower for South Asia than for most other regions of the world, and average crop NUE is on the decline in India. This inefficient use of nitrogen fertilizers has implications for agricultural productivity and environmental sustainability.Materials and MethodsUsing data from 14,669 farmers in India, this paper examined the determinants of synthetic fertilizer and manure adoption and intensity of use for rice (Oryza sativa L.) production. The latter was assessed through fertilizer expenditure rather than the traditional weight‐based method. A double hurdle model was estimated.ResultsThe study showed that farmers' decisions to adopt fertilizer or manure and the decision on use intensity were independent. Both synthetic fertilizers and manure adoption were influenced by common drivers such as access to financial resources through instruments like the Kisan Credit Card and loans, expenditure on irrigation and labour, and geographical location. In terms of barriers, the likelihood of adoption of both synthetic fertilizer and manure was lower among landowners and paddy area cultivated. The intensity of fertilizer and manure use was higher for older farmers and was positively influenced by expenditure on labour but negatively influenced by ownership of livestock. Also, synthetic fertilizers and manure use intensity were determined by regional temperature and geographical zones.ConclusionThe results of this study are useful for targeted interventions to promote sustainable fertilizer use with a focus on following recommendations in zones or among demographic groups that are currently more likely to have a high intensity of use. Similarly, the findings inform support towards increased adoption and sustainable use where fertilizer is underutilised.
