Why schedule?

•Applying irrigation water is an expensive pastime!•Incorrectly scheduled irrigation will adversely affectyour crop•Poor irrigation practice can increase the risk of pestand disease pressures•Leaching of water and nutrients - a costly exercise•Waste of resource – labour, electricity / diesel,water, fertiliser

Raingun

Applies large volumes quickly

Good in irregular shaped fields

Ease of moving from pull to pull and fieldto field

Potentially better than boom on lowerinfiltration rate soils

www.agri-tech.co.uk

Boom

Advantages:

Even distribution of water across spread width

Wetting of the entire ridge / bed environment

Big advantage over the raingun in windy conditions

Ease of movement from field to field

www.agri-tech.co.uk

Drip Irrigation

Advantages:

Ability to meet plant’s uptake need

Controlled deficit irrigation possible

Low energy requirement

Spray and irrigate

Reduced disease (eg blight) environment

Efficient use of water - placed where required

Option to fertigate

Plant Parameter

• Dendrometer– Measures the Plant

stem expansion andshrinkage as anindication of plantwater potential

• Leaf-Sen– Leaf-thickness-sensor

that accurately andcontinuously assessesleaf turgor

www.agri-tech.co.uk

Environmental

• Weather Station– Developed to maintain all

considerations of new requirementand standards

– Can be used for open fields/greenhouse applications

– Irrigation scheduling, diseaseprediction models

• Temperature– Provides an accurate and stable

reading– Up to three sensors per transmitter
