A manual colorimetric procedure for measuring ammonium nitrogen in soil and plant Kjeldahl digests
TL;DR: In this article, the authors modified an automated colorimetric analysis procedure for determining NH4+N in soil and plant digests for manual use, and compared the proposed technique with the standard distillation-titration technique.

TL;DR: In this paper, the authors dealt with sensitivities, adaptive capacity and vulnerability of agriculture to climate change, including the direct and indirect effects of changes in climate and atmospheric constituents on crop yield, soils, agricultural pests, and livestock.
Journal ArticleDOI
Actionable climate knowledge: from analysis to synthesis
TL;DR: In this article, the authors explore three case studies focused on dryland cropping in Australia, India and Brazil, and conclude that climate risk management requires holistic solutions derived from cross-disciplinary and participatory, user-oriented research.
Journal ArticleDOI
A 20-year study of NDVI variability over the Northeast Region of Brazil
TL;DR: In this paper, the authors examined the spatial heterogeneity and temporal dynamics of the Northeast Region of Brazil (NEB) using a 20-year time series of Normalized Difference Vegetation Index (NDVI) observations, derived from the National Oceanographic and Atmospheric Administration (NOAA)-Advanced Very High Resolution Radiometer (AVHRR) instrument.
