Food for chicken mixed with 50 gr. Siolit into 1000 kg. chicken food.

6.1 Results of chicken manure.

6.1.1 Nitrogen in the chicken manure

Measurements of nitrogen in chicken manure show following results for total – N, urine acid – N and ammonium – N.  

Nitrogen kg./ton manure

NH4 - N

Urine acid – N

Untreated

8,9 ± 0,1

Siolit

 The measurements show a very little standard difference, which indicate a precise determination.

6.1.2 Other nutriments in the chicken manure.

 Results for measurements of P-, K-, Na-, Ca-, Mg in Untreated, Amalgerol and Siolit figure 6.4

 6.1.3 pH in chicken manure.

Results from measurements for pH shown in figure 6.6.

    Figure 6.6 pH in chicken manure.

 Figure 6.6 show that p H is lowest in Siolit. With the results in pH and the use of the equation calculate the difference between ammonium and ammoniac in the manure. Equation:  pH = pK2 + log (NH3) / (NH4+). For Siolit this relationship is 3 % as ammoniac and 97 % as ammonium. For Amalgerol the same relationship is 46 % ammoniac and 54 % ammonium.

The conclusion in the rapport vas that the fall in pH by using Siolit in the chicken food dramatically has chances the difference between ammonium and ammoniac
