The use of drip irrigation on processing tomatoes in southwestern Ontario is increasing, especially on lighter soils. This area has always had some times during the growing season when rainfall was lacking. However in recent years, the length of time that soils are at a water deficit has increased. More growers are becoming interested in drip irrigation as a way to even out soil moisture and improve crop yields.
Drip irrigation is a big commitment, both in terms of money and time.
Consider these factors if you are going to start using drip irrigation in your fields. The water source should be your first consideration. It should give the least problems with precipitates or suspended particles. Water pressure can be inconsistent especially during periods of high water demand usually when you need it most. Now and in the future you can expect some controls and limitations as municipalities try to recover the cost of system expansion.
