Synthesis and characterization of novel pH sensitive PAAM-PMAA-CMC hydrogels and their applications in the controlled release of fertilizer
(2012-09-01)
Recently, the applications of hydrogels as a carrier vehicle for the controlled release of fertilizers in the agricultural field have been extensively proposed due to the unique properties of these materials, such as their ...
Biopolymer-Based hydrogels for agriculture applications: Swelling behavior and slow release of agrochemicals
(Springer Nature, 2019)
Hydrogels are cross-linked polymers that can absorb and hold largeamounts of water and aqueous solutions due to the presence of hydrophilic functional groups in their 3D network. These materials also serve as vehicles of ...
Fertilizante de eficiência aprimorada em plantio de eucalipto: análise econômica sob condições de incertezas
(Universidade Estadual Paulista (Unesp), 2021-11-30)
Reduzir o uso de fertilizantes é uma prioridade na busca por sistemas florestais sustentáveis. A tecnologia empregada em fertilizantes de eficiência aprimorada traz diversos benefícios aos plantios comerciais de eucalipto, ...
Characterization of a κ-carrageenan hydrogel and its evaluation as a coating material for fertilizers
novel carrageenan-based hydrogel (CBH) was developed via cross-linking and ion interaction methods to obtain a coating
for NPK fertilizer grains. Attenuated total reflectance–Fourier transform infrared analysis (ATR–FTIR), ...
Sublethal Effect of Pyriproxyfen Released From a Fumigant Formulation on Fecundity, Fertility, and Ovicidal Action in Aedes aegypti (Diptera: Culicidae)
(Entomological Society of America, 2014-04)
Dengue and dengue hemorrhagic fever are mosquito-borne viral diseases that coincide with the distribution of Aedes aegypti (L.), the primary vector in the tropical and semitropical world. With no available vaccine, ...
Substrates and controlled-release fertilizations on the quality of eucalyptus cuttings
(Departamento de Engenharia Agrícola - UFCG, 2014-11-01)
To produce cuttings with quality, the most appropriate nutritional management strategies should be sought to reduce wastage of fertilizer, while accounting for the characteristics of each substrate. This study evaluated ...
Controlled release on sand bed columns and biodegradability in soil of chitosan: Hydroxypropyl methylcellulose films
(John Wiley & Sons Inc, 2019-05)
The main purpose of this work is to prepare and characterize films based on chitosan (Q) and hydroxypropyl methylcellulose (HPMC) blends to achieve adequate properties to be used as coating of conventional fertilizers to ...
