Non-nutrient heavy metals in tomato plants cultivated in soil amended with biosolid and sugar-cane bagasse compost
(2004-12-01)
In this study, non-nutrient heavy metal concentrations (Cd, Cr, Ni and Pb) were measured in composts during the composting process, in compost/Red-yellow Latosol mixtures, and in tomato plants. Composts were produced using ...
Heavy metal nutrients in tomato plants cultivated in soil amended with biosolid composts
(2003-11-01)
The use of biosolids in horticulture could contribute to recycle residues produced by men. This study analyzed concentrations of Cu, Mn and Zn in the compost during fermentation, in the soil amended with the composts and ...
Mechanisms of solute transport and dispersion in open channels with surface storage zones
(2013)
Surface storage zones are lateral recirculation areas, which play a significant role on many physical and biogeochemical
processes in rivers. They have lower velocities and shear stresses, favoring the biodiversity of ...
Hydrodynamic Characterization of a Surface Storage Zone in a Natural Stream
(2015)
Flow developed in surface storage zones in rivers is very important for many physical and
biogeochemical processes. These regions are characterized by low velocities compared to the flow
in the main channel and long ...
Soil compaction and soybean root growth
(Springer, 1998-01-01)
Soil compaction has a negative effect and Ca was shown to enhance root growth. The effects of soil subsurface compaction and liming on root growth and nutrient uptake by soybean were studied at the Department of Agriculture ...
Extra̧ão de Macro e Micronutrientes Pela Parte Aérea de Erva-Doce EM Fuņão de Calagem e Aduba̧ão com Esterco de Cama de Frango
(2002-02-27)
A greenhouse experiment was conducted in the Soil Science Department of the Botucatu College of Agricultural Sciences (UNESP), Brazil, using a Dark Red Latosol in 25 L pots. The soil was limed to 50 and 70% of base saturation; ...
