Delineation of management zones with soil apparent electrical conductivity to improve nutrient management
(Elsevier, 2013-11)
Site-specific management demands the identification of subfield regions with homogeneous characteristics (management zones). However, determining subfield areas is difficult because of complex correlations and the spatial ...
Diagnosis of nutrient composition in fruit crops: Major developments
(2019-11-27)
Early methods of tissue diagnosis opposed the concept of critical nutrient concentrations supported by the laws of the minimum and the optimum to the more complex one of nutrient balances. But this proved to be a futile ...
Nitrogen and sulfur interaction on nutrient use efficiencies and diagnostic tools in maize
(Elsevier, 2020-05)
Nitrogen (N) and sulfur (S) critical dilution curves and the N:S stoichiometry are useful tools for evaluating nutrient status in maize (Zea mays L.). Nutrient supply for both N and S impact plant nutrient uptake, consequently ...
Plant and soil analyses. Efficient use of energy in agriculture through improved vegetable fertilization.
(Separata de: New York'S FOOD AND LIFE SCIENCES. 11(3):4-7, 1978., s.f.)
Protease na alimentação de frangos de corte
(Universidade Federal de Minas GeraisUFMG, 2012-02-16)
This experiment aimed to evaluate the effects of protease (produced by Bacillus licheniformis strain PWD-1) upon metabolization coefficient of nutrients, performance and slaughter yield from male Cobb® broilers, fed diets ...
Qualidade da forragem de pastagem nativa sob distintas alternativas de manejo.
(Pesquisa Agropecuária Brasileira, Brasília, v.37, nº 3, p.399-406, mar. 2002., 2011)
Potential for increasing soil nutrient availability via soil organic matter Improvement using pseudo panel data
(Scientific Research Publishing, 2014-07)
Fixed and random effect models were applied to a pseudo-panel data built of soil analysis reports from tobacco farms to analyze relationships between soil characteristics like soil organic matter (SOM) and soil nitrogen ...
