Lipid microspheres containing urea for slow release of non-protein N in ruminant diets
(2022-01-01)
Context: Urea is widely used in ruminant diets as a source of non-protein nitrogen (NPN), partially substituting for true protein in feed, but high levels of urea in the diet may cause toxicity. Aims: This study investigated ...
Torrefied banana tree fiber pellets having embedded urea for agricultural use
(2018-01-01)
Banana tree fibers (BF) torrefied in the absence of air and residence time of 60 min at temperatures between 180 and 600 ∘C were evaluated for its agglutination power when converted to pellets. The agglutination power was ...
Carnauba wax as a wall material for urea microencapsulation
(Wiley-Blackwell, 2019-02-01)
BACKGROUND The high ureolytic activity of rumen microbiota is a concern when urea is used in ruminant feed, because it leads to fast urea conversion, resulting in possible intoxication and lower nitrogen utilization. This ...

Análisis comparativo entre la urea agroindustrial y un aditivo acelerante de fragua (Chema) en el concreto hidráulico
(Universidad Privada del NortePE, 2023-08-20)
Los aditivos para concreto son sustancias químicas que son insumos que actúan químicamente al contacto del cemento en la modificación de algunas propiedades del cemento, tales como la resistencia a compresión a corto plazo, ...
Production of granular urea as nitrogen fertilizer
(Nova Science Publishers, 2014)
The demand for urea is continuously growing and entwined with the need for fertilizers and animal feed additives. Industrially, urea is initially produced in liquid form as a concentrated solution. Then, it can be converted ...
THE EFFECT OF 2-CHLORO-4,6 BIS (ETHYLAMINO)-S-TRIAZINE AND 3-(3,4-DICHLOROPHENYL)-1, 1-DIMETHYL UREA ON MOSAIC-INFECTED B.37161 SUGARCANETHE EFFECT OF 2-CHLORO-4,6 BIS (ETHYLAMINO)-S-TRIAZINE AND 3-(3,4-DICHLOROPHENYL)-1, 1-DIMETHYL UREA ON MOSAIC-INFECTED B.37161 SUGARCANE

Starch films for agronomic applications: comparative study of urea and glycerol as plasticizers
(Infogain Publication, 2018)
This work aims to study the effects of urea, glycerol and their mixture as plasticizers for cassava starch films, regarding their impact on the material structure, water susceptibility, barrier and mechanical properties. ...
Eco-compatible cassava starch films for fertilizer controlled-release
(Elsevier Science, 2019-08)
As an attempt to tackle the environmental issues derived from the use of non-degradable plastic and fertilizers overuse, such as irreversible soil pollution, this work focuses on the development of a fertilizer controlled-release, ...
Use of polyhydroxybutyrate and ethyl cellulose for coating of urea granules
(2013)
Fertilizers contain essential nutrients for agricultural growth and development. However, most nitrogen fertilizers are substances with high solubility of ions and are very susceptible to leaching and volatilization. To ...
