Process of fixation, imobilization and mineralization of ammonium in soil using N-15

Abstracts

The organic and inorganic forms of soil nitrogen and how they participate in the process of fixation, immobilization and mineralization of ammonium in soils were evaluated, after different periods of incubaton, utilizing two soils, a Lithic Haplustoll and a Typic Eutrorthox. The results obtained permit to suggest that : 1) The method for determination of the ammonium fixing capacity based on the extraction with 2N KC1, is considered to be subject to interferences of other soil fractions capable of retaining ammonium. 2) The increase in exchangeable ammonium content is related to the decrease in amino acids and hydrolyzable ammonium. 3) The immobilization and mineralization processes are still held under mil microbial. The forms more affected by this condition are amino acids and hydrolyzable ammonium.

As formas analisadas através do conteúdo de nitrogênio e da relação isotópica 15N/14N foram: amônio trocável, amônio fixado, aminoácidos, hexosaminas, hidroxiaminoácidos, amônio do hidrolisado e nitrogênio total do hidrolisado. Verificou-se que: 1) o método que emprega a extração com KC1 2N para determinar a capacidade de fixação do amônio adicionado, está sujeito a erros provocados pela interferência de outras funções do solo, na fixação de amônio; 2) o aumento no conteúdo de amônio trocável está relacionado com a diminuição dos aminoácidos e do amônio do hidrolisado dos solos e 3) os processos de retenção e liberação do nitrogênio do solo continuam em condições de atividade microbiana nula, sendo as formas mais afetadas aminoácidos e amônio do hidrolisado.

SUMMARY

The organic and inorganic forms of soil nitrogen and how they participate in the process of fixation, immobilization and mineralization of ammonium in soils were evaluated, after different periods of incubaton, utilizing two soils, a Lithic Haplustoll and a Typic Eutrorthox.

The results obtained permit to suggest that:

1) The method for determination of the ammonium fixing capacity based on the extraction with 2N KC1, is considered to be subject to interferences of other soil fractions capable of retaining ammonium.

2) The increase in exchangeable ammonium content is related to the decrease in amino acids and Hydrolyzable ammonium.

3) The immobilization and mineralization processes are still held under mil microbial. The forms more affected by this condition are amino acids and Hydrolyzable ammonium.

RESUMO

As formas de nitrogênio do solo e a maneira em que as mesmas participam dos processos de fixação, imobilização e mineralização do amônio no solo foram avaliadas após diferentes períodos de incubação, utilizando dois solos, um Lithic Haplustoll e um Typic Eutrorthox.

As formas analisadas através do conteúdo de nitrogênio e da relação isotópica 15N/14N foram: amônio trocável, amônio fixado, aminoácidos, hexosaminas, hidroxiaminoácidos, amônio do hidrolisado e nitrogênio total do hidrolisado.

Verificou-se que: 1) o método que emprega a extração com KC1 2N para determinar a capacidade de fixação do amônio adicionado, está sujeito a erros provocados pela interferência de outras funções do solo, na fixação de amônio; 2) o aumento no conteúdo de amônio trocável está relacionado com a diminuição dos aminoácidos e do amônio do hidrolisado dos solos e 3) os processos de retenção e liberação do nitrogênio do solo continuam em condições de atividade microbiana nula, sendo as formas mais afetadas aminoácidos e amônio do hidrolisado.
