Gypsum application may enhance the soil quality for plants in terms of chemical and physical properties. The objective this study was to evaluate effects gypsum on structural a no-tillage Red Latosol. experiment initiated September 2005 Guarapuava-PR, with applications 0; 4; 8; 12 Mg ha-1 surface. In November 2009, two blocks were sampled from 0-0.3 m layer visual evaluation structure (Sq) determine aggregate-tensile strength (ATS). Soil penetration resistance (PR) gravimetric moisture (H%)...
A compactação do solo é um problema comum nas lavouras e que influi tanto no crescimento na produtividade das culturas, como conservação da água. fim de estudar esse problema, cinco espécies plantas adubação verde inverno (ervilhaca, nabo forrageiro, tremoço branco, aveia preta branca) foram cultivadas em quatro perfis com crescentes níveis subsuperfície (Ds: 1,31, 1,43, 1,58 1,70 Mg m-3). O experimento foi realizado vaso sob condição casa vegetação FCA/UNESP, Botucatu (SP), 1998, utilizando...
Annual crop yield and nutrition have shown differentiated responses to modifications in soil chemical properties brought about by gypsum application. The aim of this study was evaluate the effect application rates on a Latossolo Bruno (Clayey Oxisol), as well maize-barley succession under no-till. experiment set up November 2009 Guarapuava, Parana, Brazil, applying 0.0, 1.5, 3.0, 4.5, 6.0 Mg ha-1 surface upon sowing maize, with barley. Gypsum decreased levels Al3+ Mg2+ 0.0-0.1 m layer...
Applications of phosphogypsum (PG) provide nutrients to the soil and reduce Al3+ activity, favoring fertility root growth, but allow Mg2+ mobilization through profile, resulting in variations PG rate required achieve optimum crop yield. This study evaluated effect application rates splitting on a Typic Hapludox, as well influence annual crops under no-tillage. Using (4 × 3) + 1 factorial structure, treatments consisted four (3, 6, 9, 12 Mg ha-1) three split applications (P1 = 100 % 2009; P2...
Biologically active peptides produced from fish wastes are gaining attention because their health benefits. Proteases by halophilic microorganisms considered as a source of enzymes in high salt systems like residues. Hence, the aim this study was bioprospection for production proteases to prove application peptide production. Halophilic were isolated saline soils Mexico and Bolivia. An enzymatic screening carried out detection lipases, esterases, pHB depolymerases, chitinases, proteases....
Abstract One of Brazil's efficient soil and water conservation practices is the no‐tillage system (NTS). Nonetheless, erosion during rainfall still causes losses in this system. Therefore, study aimed to assess surface runoff different cultivation systems sediment production events. In macro‐plot 1 (non‐terraced catchment [NTC]), we adopted NTS management with up‐ down‐slope farming without including mechanical control practices, which most regional producers use. 2 (best [BMPs]), optimized...
Chemical treatments to break bud dormancy are necessary in vineyards that experience mild winters. Cuttings with a single were sprayed 1.5 or 3.0% garlic extract 1.5% hydrogen cyanamide. The controls treated distilled water. Three lots of canes submitted 0, 168, 336, 508 chilling hr (≤6.0°C), respectively, before spraying. All improved and advanced sprouting over the control. most effective treatment for release was H<sub>2</sub>CN<sub>2</sub>, up 80% after 35 days, even unchilled cuttings....
This study evaluated soil chemical attributes, leaf nutrient concentrations and grain yield of corn (Zea mays), barley (Hordeum vulgare), common bean (Phaseolus vulgaris) wheat (Triticum aestivum) as affected by phosphogypsum (PG) rates split application to a Typic Hapludox under no-till from Southern Brazil. A Randomized complete block design was used, with factorial treatment structure (5 x 2) consisting increasing PG (0, 3, 6, 9 12 Mg ha−1) either in single or (half dose, two consecutive...
Na região do Cerrado, as atividades agrícolas têm provocado impactos negativos, principalmente, na qualidade solo e da água. Tanto em sistemas de exploração agrícola ou pecuária, com diferentes manejos, a degradação física é uma das consequências redução produtividade. O objetivo deste trabalho foi verificar infiltração água no sob influência manejo um Latossolo Vermelho distrófico dos Cerrados. Os tratamentos foram os seguintes manejo: a) vegetação nativa; b) implantação lavoura soja...
Host factors that influence Congenital Zika Syndrome (CZS) outcome remain elusive. Interferons have been reported as the main antiviral factor in and other flavivirus infections. Here, we accessed samples from 153 pregnant women (77 without 76 with CZS) 143 newborns 66 exposed to ZIKV conducted a case-control study verify whether interferon alfa receptor 1 (IFNAR1) lambda 2 4 (IFNL2/4) single nucleotide polymorphisms (SNPs) contribute CZS outcome, characterized placenta gene expression...
O objetivo deste trabalho foi avaliar: (i) a relação entre degradação de pastagens colonião manejadas com queima, e as modificações nas propriedades físicas morfológicas um Argissolo Vermelho-Amarelo da Amazônia; (ii) o crescimento radicular diferentes níveis degradação; (iii) potencial recuperação degradadas introdução andropógon.
