(Universidade Federal de Santa MariaBRRecursos Florestais e Engenharia FlorestalUFSMPrograma de Pós-Graduação em Engenharia Florestal, 2012-02-23)
Understanding of the involved issues in nutritional dynamics process in eucalyptus stands is the base to sustainable management. Objective this study was to determine the nutritional dynamic in Eucalyptus urophylla x ...
Environmental performance of biological nutrient removal processes from a life cycle perspective
The goal of the present study is to assess different alternatives for a wastewater treatment plant module with capacity to remove nutrients biologically, taking into account present Argentine regulations for effluent ...
Phosphorus effects on biomass accumulation and nutrient uptake and removal in two potato cultivars
Information on the effect of P fertilization on nutrient uptake and removal by potato (Solanum tuberosum L.) cultivars is required for proper soil nutrient management. This study was performed to evaluate how dry matter ...
Nutrient Uptake and Removal by Potato Cultivars as Affected by Phosphate Fertilization of Soils with Different Levels of Phosphorus Availability
(Soc Brasileira De Ciencia Do Solo, 2017-01-01)
Studies in the past decades have focused on how tuber yield of potato grown on different types of soil is affected by phosphate fertilizer rates. However, little is known about the effects of phosphorus availability in the ...
REMOCION DE NUTRIENTES EN UN HUMEDAL ARTIFICIAL UTILIZANDO PLANTULAS DE DOS ESPECIES DE MANGLE (Rhizophora mangle y Laguncularia racemosa)
ABSTRACT During two cycles of shrimp farming we assessed the ability of nutrient removal in two species of mangrove (Laguncularia racemosa and Rhizophora mangle) in a constructed wetland in three experimental ponds of 10 ...
Nutrient removal using two species of mangrove (Rhizophora mangle and Laguncularia racemosa) in experimental shrimp (Litopenaeus vannamei) culture ponds
(Ciencias Marinas, 2012)
The nutrient removal capacity of two species of mangrove (Rhizophora mangle and Laguncularia racemosa) was assessed in shrimp (Litopenaeus vannamei) culture ponds. One pond contained R. mangle seedlings and another L. ...
