Methodology:
The isothermal method was used with 3.5 hours allowed for equilibration. Both liquid and solid phases were analyzed. $\ce{NH4^{+}}$ was determined by a distillation method [1] $\ce{P2O5}$ by the citrate method [2] and potasssium gravimetrically as the tetraphenylborate. The solid phase was analyzed by the Schreinemaker's method.

Experimental Data
The authors present the following equation: y = A + 0.11 x, where y = total plant nutrient, and x = the mass ratio K2O/N. The following values for the parameter, A, are given:
| $T$ (°C) | 1st coef. |
|---|---|
| 0 | 26.11 |
| 10 | 28.4 |
| 20 | 30.48 |
| 30 | 33.0 |
