Quick quiz

3. What are the two methods of pollination?Give an advantage for each one.self = no other flowers needed, no insects needed, not dependent on weathercross = get hybrid vigour, better offspring than parents

Uses of ICT to the grower1. Record keeping.2. Monitoring the growing environment.3. Computer models.4. Technical information

Record keeping

With all production systems, records are essential for

good management. When a crop is planted, what the

inputs have been, when it will be ready for harvest and

how it has been cultivated can all contribute to essential

record keeping.

Monitoring the growing environment

Data-loggers can be linked to a PC to record plantenvironmental factors. These might be:□ Light□ Water□ Nutrients□ Temperature of propagators

Light

Light sensitive data-loggers record changes inlight intensity onto a PC.This information can thenbe used to turn lighting onand off in a glasshouse orPropagator, thus

maximisingthe necessary light for thegrowing crop.

Water and nutrientsData logging sensors in thesoil detect moisture levelsand record these at a PCinterface.This data is then used toprovide information onirrigation, or it can be usedto turn on automaticirrigation systems thatdirectly access the growingcrop. The same could bedone with nutrient levels.

Temperature and humidity A data-logging hygrometer measures soil

moisture andhumidity.This information can be used to either execute changes in humidity and temperature, or inform the grower.Carbon dioxide levels can also be monitored by data-loggers.

Computer models

Information on the growing environment is put into a computer and then a programme used to

modelthe outcome for a particular crop.Inputs can be tested before being committed in the field, saving costly mistakes.

Technical information

The internet, advisory sites and Manufacturers’ web-sites can be used to gather technical information on caring for a crop.Satellite photos can be used to monitor disease and cropping without walking over growing crops.

Crops give particular colours when photographed from space.
