The possibility of simplifying the seedling method for determining soil fertility






Roczniki Nauk Rolniczych I Lesnych 50: 12-30

The possibility of simplifying the seedling method for determining soil fertility

Use of perforated vegetation pots permits watering by continuous soaking from the bottom. Growth (dry or fresh wt.) of the plants is sufficient indication of the amt. of K or P they have taken up from the soil. Tomato and Galinsoga parviflora are suggested as indicator plants suitable for the simplified method. Quantitative comparisons with results obtained by Neu-bauer's method are made, but no relationships between the 2 methods are explicitly stated and no .calibration curves ar e supplied.
