Objetivou-se avaliar a eficiência de um fertilizante organomineral (FOM) granulado a partir da mistura de turfa e cloreto de potássio na produção de gramíneas, em comparação ao cloreto de potássio comercial. O experimento foi conduzido em vasos em casa de vegetação. A planta indica...
The objective of this work was to evaluate the efficiency of granulated fertilizers based on potassium chloride with humic acids in the production of dry matter and the accumulation of macronutrients in corn plants. The experiment was carried out in a greenhouse, using soil sa...
The exploitation of natural resources has grown mainly due to the high rate of population growth that changed over time around the planet. Water is one of the most needed resources essential for survival. Despite all the efforts made to improve water security, an environmental...
This study quantify the total organic carbon content, light fraction organic matter (LFOM), and soil organic matter fractions (from chemical and physical fractionations) in four different cultivation areas: 1 and 2) rubber tree clonal plantations (FX 3864 and IAN 873); 3) a pasture;...
As atividades agroindustriais geram grandes quantidades de resíduos sólidos orgânicos. Por essa razão, são responsáveis por estabelecer metas e estratégias de gerenciamento de seus resíduos, visando, sempre que possível, à reutilização, à reciclagem e ao tratamento. Realizou-se um estudo de caso&...
O Sistema Plantio Direto (SPD) aplica técnicas agrícolas conservacionistas para preservação do solo, controlando processos de erosão. Para isso, é necessário conhecer as características do relevo que afetam a dinâmica e o poder erosivo da água na microbacia hidrográfica (MBH) em que o&#...
Agriculture, forestry and other land uses are currently the second highest source of anthropogenic greenhouse gases (GHGs) emissions. in soil, these gases derive from microbial activity, during carbon (c) and nitrogen (n) cycling. to investigate how Eucalyptus land use and growth period ...
Chemical soil analysis data can be expressed by weight (i.e., gravimetric basis) or volume (i.e., volumetric basis) of the fine earth (sieved >=2 mm), resulting in different units, cmolc kg-1 and cmolc dm-3, respectively. The research problem is that the difference between methods&#x...
A teaching experiment on supervised pattern recognition in chemometrics was proposed in this tutorial to introduce partial least squares discriminant analysis (PLS-DA). A new approach of the experiment published in the first tutorial of this series was revisited and employed to the clas...
