With irrigation you can grow vegetables in the dry season
Low cost drip irrigation saves water, lets you grow more tomatoes and double your profits.
Drip irrigation applies water drop by drop
The slow drip keeps the soil loose so water and air can reach the roots. Drip irrigation is not as stressful for the plants as flood irrigation, where the soil gets very wet all at once and then dries out. With drip irrigation the water reaches slowly and steadily deep into the soil. The drops do not touch the tomato flowers and do not knock them off.
Drip irrigation helps avoid diseases. And if you do spray a product against pests, drip irrigation does not wash it off.
