A soil sample should be taken at least once every three years, or when there is a change in crop to be grown. A soil sample should also be taken if problems occur during the growing season.

Generally, a full soil analysis takes 8 working days to complete.

Advantages of the float system over the conventional system;

o Reduced seedbed area, one fifth of space required.

o Reduced time to pulling seedlings and easier pulling

o Transplanting can be done during any time of the day

o Fewer chemicals and in smaller quantities

o Less water , fertilizers and labour

o Produces superior, more uniform and stress tolerant seedlings

o Offers additional flexibility in planting following pulling, i.e., seedlings take longer to wilt compared to conventionally produced bare-rooted seedlings

o Improved survival and early growth of transplanted seedlings

o Facilitates easier field management, arising from a more uniform crop

o Unused pulled seedlings can be inserted back into trays and re-floated without consequence for a later planting.

The best time for sampling is after the rains and when the soil has dried out e.g. April and May in Zimbabwe

Due to the slight solubility of lime in water, its movement in the soil is also not as effectively as other soluble fertilizers. Lime must be in direct contact with soil acids for it to react effectively. This is best accomplished when it is mixed with the soil. Water is also required for the reaction to occur.
