Accumulation and efficiency of nutrient use in crop systems in second crop under no-tillage
(Empresa Brasil Pesq Agropec, 2021-01-01)
The objective of this work was to evaluate phytomass production, nutrient cycling, and efficiency of nutrient use by single and intercropped crop systems, in the second crop, under no-tillage. The experiment was carried ...
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 ...
Ciclagem de macronutrientes no cultivo de alface hidropônica
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Agricultura e Ambiente - PPGAA-ArCâmpus Araras, 2021-11-29)
The search for sustainability in agricultural production has been reflected in the management of hydroponic systems that use the Laminar Nutrient Flow Technique (NFT). The reuse of nutrient solutions becomes an alternative ...
Estimating nitrogen, phosphorus, potassium, and sulfur uptake and requirement in soybean
(Elsevier, 2021-07)
Estimation of crop nutrient demand, seed nutrient removal, and nutrient use efficiency (yield to nutrient uptake ratio) are crucial for pursuing both balanced nutrition and more sustainable farming systems. However, the ...

Litterfall mass and nutrient fluxes over an altitudinal gradient in the coastal Atlantic Forest, Brazil
(Cambridge University Press, 2017)
Litterfall is one of the most important pathways through which nutrients are recycled in the terrestrial biosphere. In tropical soils, which are generally low in essential nutrients such as phosphorus and cations, the flux ...
Growth and mineral nutrition of baru (Dipteryx alata Vogel) in nutrient solutionCrescimento e nutrição mineral do baru (Dipteryx alata Vogel) em solução nutritiva
(Departamento de Engenharia Agrícola - UFCG, 2018)
A sensor for monitoring the volume of nutrient in a solid substrate-based growth media by using electrochemical admittance spectroscopy
(Elsevier B.V., 2002-12-10)
A sensor was fashioned to monitor the volume of nutrient in a solid substrate-based growth media by using electrochemical admittance spectroscopy. Several experimental parameters were investigated (i.e. The use of two- or ...
