Evaluating Nitrogen Release Rates of Commercial Slow-Release Urea Products Using Brix Value Analysis: A Validation Study Comparing Two Methods
The stability of three slow-release urea products (SRU) and a non-protected granulated urea (U) product was assessed based on their Brix value and total Nitrogen (N) Kjeldahl concentration in water. Each SRU and U products (10 g) was mixed with 50 ml of distilled water at 23.5 °C for various duratio...

Each SRU and U products (10 g) was mixed with 50 ml of distilled water at 23.5 °C for various durations: 1, 3, 6, 12, and 24 h. After each period of time, Brix values and total N concentrationswere measured in the aliquots. The N concentrations in all products exhibited time-dependent changes. A positive and linear correlation was observed between the total N in water and Brix values. The R2 between both methods was 0.97. Thus, the Brix value serves as a convenient and effective method to evaluate the relative rate of N release for different SRU products. La estabilidad de tres productos de urea de liberación lenta (ULL) y un producto de urea (U) granulada no protegida se evaluó en función de su valor Brix y la concentración total de nitrógeno (N) Kjeldahl en agua. Cada producto ULL y U(10 g) se mezcló con 50 ml de agua destilada a 23,5 °C durante varios períodos: 1, 3, 6, 12 y 24 h. Después de cada período de tiempo, se midieron los valores Brix y las concentraciones de N total en las alícuotas. Las concentraciones de N en todos los productos mostraron cambios dependientes del tiempo. Se observó una correlación positiva y lineal entre el N total en agua y los valores Brix. El R2 entre ambos métodos fue de 0,97. Por lo tanto, el valor Brix surge como un método conveniente y eficaz para evaluar la tasa relativa de liberaciónde N de diferentes productos de ULL.
