As illustrated at Figure 2, PCA showed that water conditions at sites 2 and 3 were similar, positioning most of the samples from these sites to the negative side of Axis 1, associated with the higher figures for total nitrogen, total ammoniacal nitrogen, total phosphorus, orthophosphate, chlorophyll a and water temperature.
Ammoniacal leaching of cobalt crusts using S[O.sub.2] as the reductant has been reported(18).
For silage quality analyses, pH, ammoniacal nitrogen and water activity were assessed using the juice and the finished silage.
Effects of post-layup ammoniacal copper zinc arsenate treatment on appearance and flexural properties of Douglas-fir glued laminated beams.
This approach minimizes the effects of residual binder, and the accumulation of other residuals (i.e., core binder solvents and ammoniacal nitrogen) is prevented.
When applied to the soil, urea suffers enzymatic hydrolysis, releasing ammoniacal N (Cantarella, 2007).
Samples were homogenized and divided into three portions: one portion was placed in plastic bags and frozen for ammoniacal nitrogen (N-N[H.sub.3]) analysis; another portion was analyzed for its chemical composition; a small portion was used to determine its pH with a digital potentiometer, using 9 g of the sample in 60 mL of distilled water, following Silva and Queiroz (2002).
With the objective of increasing the efficiency of nitrogenized fertilizers, the ammonium nitrate fertilizer, ammonium sulfonitrate (Entec[R]) was recently released on the market that has 26% N total and 12% sulfur, mostly in the ammoniacal form (18.5% ammoniacal and 7.5% in the nitric form).
This is supported by Richardson (1991), who reported comparable performance for CCA and ammoniacal copper quat with a CuO to DDAC ratio of 1:1, which led to the introduction of this formulation as ACQ-A in the AWPA standards.
Recently introduced low-nitrogen hotbox processes offer significant reductions in ammoniacal nitrogen and free formaldehyde but are more costly.
375, of August 2006 (Berton & Nogueira, 2010), defined as follows: Kjeldahl-N = 29.1 g [kg.sup.-1], ammoniacal N = 2.18 g [kg.sup.-1], Nitrate + Nitrite = 50.6 mg [kg.sup.-1] and Mineralization Factor (MF) = 20%, with N extraction and determination in the sewage sludge according to the procedures described in Abreu et al.
