Tissue Analysis
Analysis of the soil nutrients showed greatly enhanced levels of many of the nutrients. The changes that occurred in the soil were also reflected in tissue analysis of the leaves. The plants grown in the soil treated with Bio-Sulphur had higher levels of nutrients in the leaf tissue compared to those in the control.

Yield Analysis

The plants treated with Bio-Sulphur had superior vegetative growth and reached stages such as flowering and maturation 7-10 days ahead of those plants not treated with Bio-Sulphur.
The average numbers of tubers per plant in the treated plots were double in comparison to the control plot, which is reflected in the yield differences. Plots treated with Bio-Sulphur produced significant increases in tuber yield. The total tuber yield from the treated plots is 7.1mt/ha more than those receiving no applications.

Yield Comparison between Bio-Sulphur treated Plots and Untreated Plots

It was also commented that the potato skins were clearer, brighter with less blemishes and evidence of disease. Due to the change in soil texture the potatoes were easier to lift and cultivate.
Bio-Sulphur changed the soils chemical and physical properties enhancing not only the availability but the absorption of nutrients by the plants. The unlocking of nutrients reduces the need for additional fertiliser inputs and the soils reserves are fully utilised.
