“…When samples from 10 -20 cm depth were used, variation accounted by the regression was smaller (R 2 ¼ 0.47). Findings from Bronson et al (2001) also showed a strong positive relationship (R 2 ¼ 0.77) between soil total N content and the mineralizable-N determined by the anaerobic incubation of Waring and Bremner (1964) for rice and wheat soils. Several workers have found that many biological processes affecting soil N availability are closely related to total soil N content, which is also related to organic matter content (Keeney and Nelson, 1982) and substrate availability (Black et al, 1998;Purnomo et al, 2000aPurnomo et al, , 2000b.…”

Excess vigour is a problem in cool climate vineyards in Australia due to high soil Nfertility. High and low vigour blocks in three cool climate vineyards in Victoria, Australia, was surveyed. The relationship between soil N-fertility and grapevine vigour was tested. Vine vigour was reflected in measured internode length and leaf petiole N content. The average daily Nmineralization rate from soil organic matter (SOM) varied among the sites. Laboratory incubations revealed a positive relationship between soil total N content and average daily mineralizable-N in most sites. However, there are other factors involved in promoting excess vigour those to be taken into account.

“…Nitrogen mineralization in aerated soils is noticeably different from submerged soils. In flooded and anaerobic conditions, a higher concentration of total organic nitrogen results in higher N mineralization ( Bronson et al, 2001 ; Bhardwaj et al, 2020 ). However, under aerobic conditions, soil water fluctuations, as in wheat cropping season, usually result in a greater production of NO 3 – -N ( Nunan et al, 2000 ).…”

PurposeOne of the serious constraints for the integration of organics in soil fertility plans is the release and availability of nitrogen (N) to match the critical growth stages of a crop. The interplay between organic amendment characteristics and soil moisture conditions can significantly affect the nutrient release and availability, especially for dryland crops like wheat. In this study, the effects of integrated nutrient management strategies using diverse qualities of organic amendments on daily N mineralization and its availability to plants during the full growing season of the wheat crop were analyzed in a 10-year experiment.MethodsThe management included (1) F, inorganic fertilizers at 100% rate, compared to a reduced rate of inorganic fertilizers (55% N) supplemented with organic inputs via (2) GM, green manuring, (3) LE, legume cropping and its biomass recycling, (4) WS, wheat stubble retention, (5) RS, rice stubble retention, and (6) FYM, farmyard manure application, during the preceding rice season. Ion exchange resin (IER) membrane strips were used as plant root simulators to determine daily NH4+-N and NO3–-N availability in soil solution during the full wheat growing period.ResultsTotal available N for the full season was in the following order: GM (962 μg cm–2) > F (878 μg cm–2) > LE (872 μg cm–2) > FYM (865 μg cm–2) > RS (687 μg cm–2) > WS (649 μg cm–2). No significant differences were observed in NH4+-N availability throughout the cropping period as compared to NO3–-N which showed significant differences among management at critical crop growth stages.ConclusionLegume biomass incorporation (GM, LE) and farmyard manure (FYM) based management provided the most consistent supply equivalent to or even exceeding 100% inorganic fertilizers at several critical stages of growth, especially at tillering and stem elongation. Integration of organics in management increased nitrogen use efficiency 1.3–2.0 times, with cereal crop residue-based management having the highest efficiency followed by legume biomass incorporation.
