Yield of crop measured in Kg per Sq M (Tomato)
35 tomato plants are grown in a circular area of 1.77 Sq M using DI methods, producing minimum 2.2 Kg per plant. Plastic drip and furrows are spaced at 40 cm and planted at intervals of 40 cm in open fields. DI achieves the highest concentration of growth for all irrigation systems suitable for semi-arid climates, accounting for 60% of the planet.

DI Yield of crop measured in plants per Sq M (Lettuce)
184 lettuce plants – butter and batavia – are grown in a circular area of 1.77 Sq M using DI methods. Plastic drip and furrows are spaced at intervals of 40 Cm and planted at 10 Cm intervals.

*Drip irrigation needs 2 bar pressure plus a filtered water supply which is not possible in areas of Sub Saharan Africa.
*Sources for yields of conventional and drip are California Government and SAB Agriculture Italy. See URL in text box.
*Production yield is 56.8 t/ha (5.6 Kg / M2) with drip fertilisation compared to 33.5 t/ha with lateral infiltration. <https://www.sabspa.com/en/crops/tomato-drip-irrigation/>

Savings for the farmer using DI
Dixon Irrigation saves all the costs of heavy machinery and pollution from diesel fuel, synthetic fertiliser, 25,000 M of plastic pipe pollution per hectare and dangerous chemicals, AKA Glyphosphate, used for the uncontrolled water run-off from furrow irrigation. Dixon Irrigation systems need none of these costly, polluting and contaminating methods used in other farming systems.
