Relationships Between Soil Nitrogen Availability Indices, Yield, and Nitrogen Accumulation of Wheat

Soil Science Society of America Journal, 2002
The success of variable rate N fertilizer application rests on our ability to predict the contribution of soil N to growing crops. We assessed relationships between soil N availability indices (SNAIs), yield, and total N accumulation of wheat ( Triticum aestivum L.) grown in a typical glacial

Influence of nitrogen fertilization on broccoli yield, nitrogen accumulation and apparent fertilizer-nitrogen recovery

Canadian Journal of Plant Science, 1995
An understanding the relationships between N-fertilization rate, crop-N recovery, residual inorganic N in soil and crop yield can assist in making N fertilizer recommendations which balance crop value and environmental risk. Nitrogen was applied to three plantings of broccoli at 0, 125, 250, 375, 500 and 625 kg N ha−1 as a broadcast application of ...

Nitrogen accumulation, partition, and nitrogen-use efficiency in canola under different nitrogen availabilities

Communications in Soil Science and Plant Analysis, 2002
Nitrogen (N) accumulation and its partition in a canola (Brassica napus L. ssp. oleifera var. annua) crop growing under different N availabilities were evaluated. Spring canola (cultivar Printol) plants were grown with 0, 30, 60, 90, 120, or 150 kg N ha− 1 applied at sowing.

Nitrogen deficiency-induced molybdenum accumulation in wheat

Journal of Plant Nutrition, 2022
In the present study, we conducted experiments using wheat to elucidate whether the increased accumulation of molybdenum in leaves under nitrogen deficiency is due to the plant’s own metabolic response, and further to estimate the role of molybdenum in the nitrogen deficiency response.

Nitrogen addition promotes soil carbon accumulation globally

Science China Life Sciences
Soil is the largest carbon (C) reservoir in terrestrial ecosystems and plays a crucial role in regulating the global C cycle and climate change. Increasing nitrogen (N) deposition has been widely considered as a critical factor affecting soil organic carbon (SOC) storage, but its effect on SOC components with different stability remains unclear.

Nitrogen Accumulation and Residual Effects of Nitrogen Catch Crops

Acta Agriculturae Scandinavica, 1991
The nitrogen accumulation in Italian ryegrass (Lolium multiflorum Lam.), perennial ryegrass (Lolium perenne L.), white mustard (Sinapis alba L.) and tansy phacelia (Phacelia tanacetifolia L.), unde...

Plant Nitrogen Accumulation Dynamics in Rice in Response to Nitrogen Management

Communications in Soil Science and Plant Analysis, 2010
This study investigates the effect of rice nitrogen (N) management on the dynamics of plant nitrogen accumulation (PNA) during internodal elongation (IE) in relation to grain yield. Four field experiments were conducted in two soils with six preflood N treatments. The PNA was monitored for 3 weeks, starting at the beginning of IE (BIE).

Nitrogen Accumulation in Successions

1974
Nitrogen in ecosystems has been determined as a function of time of plant succession in the entire ecosystem, in its biomass, and in its soil alone.

Nitrogen accumulation in kaolin mining wastes in Cornwall III. Nitrogenous fertilisers

Plant and Soil, 1979
In the establishment of a grass cover on china clay waste it is necessary, as in most land restoration, to supply fertiliser nitrogen in substantial amounts. However the objective of nitrogen accumulation is restricted in south west England by severe leaching.

Early season nitrogen accumulation in winter wheat

Journal of Plant Nutrition, 2000
Abstract Cereal rye (Secale cereale L.) is widely used as a winter cover crop to conserve soil residual nitrogen (N) in the mid‐Atlantic region of the United States. Cereal rye, however, has agronomic drawbacks that may make other winter small grain crops more desirable alternatives.
