An investigation of the duration of phosphorous fertilization effects on phosphorous and nitrogen cycling patterns of Pinus elliottii plantations in the southern Cape

, 1992
Includes bibliographical references.The effects of phosphorus fertilization and its duration of impact on nutrient cycling patterns in Pinus elliottii plantations were investigated by examining soil phosphorus and nitrogen turnover and litterfall in a 8,

Nitrogen fertilization affects silicon concentration, cell wall composition and biofuel potential of wheat straw

, 2014
Nitrogen is an essential input factor required for plant growth and biomass production. However, very limited information is available on how nitrogen fertilization affects the quality of crop residues to be used as lignocellulosic feedstock.

Nitrogen fertilization plot level data - a Finnish case study

The data is based on the fertilization study where we evaluated the spatial evenness of nitrogen (N) fertilization (measured fertilization dose on circular plots with radius of 7,98 m) in fertilized treatments and effects of fertilization treatments ...

Response of total (DNA) and metabolically active (RNA) microbial communities in Miscanthus × giganteus cultivated soil to different nitrogen fertilization rates

, 2021
Miscanthus x giganteus is a promising high-yielding perennial plant to meet growing bioenergy demands but the degree to which the soil microbiome affects its nitrogen cycling and subsequently, biomass yield remains unclear.

Concepts and Rationale for Regional Nitrogen Rate Guidelines for Corn, April 2006

, 2006
Nitrogen (N) is typically one of the largest corn fertilization expenses. Nitrogen application is critical because it signifi cantly improves corn yield in many crop rotations.

Agronomic and qualitative traits of common bean as a function of the straw and nitrogen fertilization

Pesquisa Agropecuária Tropical, 2017
The no-tillage system can change the nitrogen dynamics in the soil, being necessary to adjust the nitrogen fertilization in order to provide this nutrient during critical phases of the common bean growth.

Nitrogen in Feed and Fertilizer

Journal of AOAC INTERNATIONAL, 1973
Abstract Low values by Raney powder method 2.056 have been obtained on a few samples from one manufacturer. The values ranged from 0.2 to 5.0% nitrogen low. In relation to pollution, further work is reported in investigating digestion conditions and use of copper as a catalyst in Kjeldahl digestions.

Growth and yield response of maize (Zea mays var. saccharata) to different nitrogen fertilization sources and rates [PDF]

Journal of Central European Agriculture
Nitrogen is an essential plant nutrient and a major yield-determining factor, required for normal vegetative growth and grain development of maize. Applying nitrogen requires appropriate fertilization management to achieve efficient nutrient utilization.
