Nutrient accumulation curves in fruits and nutrient export by seeds and hulls harvesting of physic nut (Jatropha curcas L.)
(Univ Estadual Londrina, 2014)
There is little information on the nutritional management of physic nut (Jatropha curcas L.). This study aimed to measure the nutrients accumulation during the growth of fruits in physic nut and the nutrients export from ...
Estimation of nutrient export in eucalypts genotypes under different harvest intensities in Southern BrazilEstimación de la exportación de nutrientes en genotipos de eucalipto bajo diferentes intensidades de cosecha en el sur de Brasil
(2020-03-01)
The study of the nutrients removed with forest harvesting is presented as an essential fator favoring the sustainable use of forest stands. The research was carried out in an experimental area in Horto Florestal Terra Dura ...
Modifying harvesting time as a tool to reduce nutrient export by timber extraction: a case study in planted teak (Tectona grandis L.f.) forests in Costa Rica
(2016)
Despite its low nutrient concentration, the high amount of biomass accumulated in the tree stem makes it an important nutrient sink. Hence, nutrient loss through timber removal at harvesting is a major cause of nutrient ...
Application of thermal sums concept to estimate the time to harvest new banana hybrids for export
(ELSEVIER SCIENCE BV, 2011)
Application of the thermal sum concept was developed to determine the optimal harvesting stage of new banana hybrids to be grown for export. It was tested on two triploid hybrid bananas, FlhorBan 916 (F916) and FlhorBan ...
Dynamics of Harvest Subcontracting
(Wiley, 2012-11-28)
A historical perspective of three export agro-industries in Argentina (lemons, sweet citrus and tobacco) illustrates the range of factors that may foster subcontracting and the choice of subcontracting modalities. The case ...
Sustainable use of eucalypt biomass grown on short rotation coppice for bioenergy
(Elsevier B.V., 2016-07-01)
Bioenergy is one of the alternatives to reduce the dependence of global energy on fossil fuels. The short rotation coppice (SRC) of eucalypt species appears as an interesting option for forest biomass production in a short ...
Biomass production and nutrient content in different Eucalyptus genotypes in Pampa Gaucho, Brazil
(Univ Federal Rural Pernambuco, 2019-01-01)
The objective of this study was to estimate the biomass, nutrient stocks, and simulate the export of nutrients, in different genotypes of Eucalyptus. The experiment was conducted in Sao Gabriel, RS, Brazil, in 43-month-old ...
Exportação de nutrientes minerais por frutos de aceroleira colhidos em diferentes épocas do ano
(Sociedade Brasileira de Fruticultura, 2008-09-01)
A aceroleira produz, no Nordeste brasileiro, de quatro a seis safras por ano e é de se esperar que as exportações de elementos minerais variem em função das diferentes épocas de colheita e das progênies, entre outros ...
Nutrição e produtividade do crambe em razão da adubação de semeadura na safrinha
(2013-05-01)
The interest in crambe (Crambe abyssinica) cultivation in Brazil is on the rise, whereas information on the nutrient requirements for this crop is scarce. The objective of this work was to evaluate the effect of ...
