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

Why schedule?
Increase yieldEnhance qualityRepeat results year after yearSave costs – water / electricity, fertilisers, labourEnvironmental friendlyFast ROI

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
