Phosphorus and potassium balance in a corn-soybean rotation under no-till and chiseling
(2013-05-01)
Nutrient use efficiency has become an important issue in agriculture, and crop rotations with deep vigorous rooted cover crops under no till may be an important tool in increasing nutrient conservation in agricultural ...
Herbivory and eutrophication mediate grassland plant nutrient responses across a global climatic gradient
(Ecological Society of America, 2018-03-31)
Plant stoichiometry, the relative concentration of elements, is a key regulator of ecosystem functioning and is also being altered by human activities. In this paper we sought to understand the global drivers of plant ...
Effects of Climate and Atmospheric Nitrogen Deposition on Early to Mid-Term Stage Litter Decomposition Across Biomes
(Frontiers Editorial, 2021-07-14)
Litter decomposition is a key process for carbon and nutrient cycling in terrestrial ecosystems and is mainly controlled by environmental conditions, substrate quantity and quality as well as microbial community abundance ...
Growth and body nutrient deposition of two broiler commercial genetic lines
(Fundação APINCO de Ciência e Tecnologia Avícolas, 2008-06-01)
The objective of this work was to study growth and body nutrient deposition profiles of male and female Cobb and Ross broilers using Gompertz equations. A total number of 1,920 one- to 56-day-old broilers were used. A ...

Crescimento e deposição dos nutrientes da rã-touro na engorda: ajuste de modelos não lineares
(Universidade Estadual Paulista (Unesp), 2013-08-16)
O objetivo foi descrever o crescimento em peso vivo, do fígado, do corpo adiposo, a deposição dos nutrientes corporais e das coxas, do consumo da dieta, e avaliar a eficiência proteica da dieta para rãs-touro na fase de ...

Retorno de nutrientes ao solo via deposição de serapilheira de quatro espécies leguminosas arbóreas na região de Botucatu - São Paulo, Brasil
(2004-06-01)
The annual litter fall production and the concentrations of macronutrients of four leguminous tree species were evaluated. The experiment was installed in a distrophic red yellow latosol (Oxisol), derivative of the Bauru ...
