Evaluation of soil water and plant nitrogen Status by nuclear techniques

  • 1. International Atomic Energy Agency, Vienna (Austria)

Description

Methodologies used to estimate soil water and nitrogen status of crops in field experiments are studied. Sampling procedures in a pasture experiment, consisting of three soil transects of 1.8 x 96m, one bare, one cropped to rye grass and one to alfafa, are discussed. Data are analysed with respect to soil water contents measured through the use of neutron probes, N fertilizer uptake using 15N labelled fertilizer and N2 fixation, also using isotopic methodology.

Abstract (Portuguese)

Estudam-se metodos usados na estimativa da agua do solo e do conteudo de nitrogenio da colheita em experimentos de campo. Discutem-se procedimentos de amostragem em pastagens constituidas de tres seccoes de solo de 1,8 x 96m, sendo uma sem plantacao, uma com alfafa e outra com azevem. Avalia-se o conteudo da agua do solo atraves de metodologia isotopica. (M.A.C.)
