|Tomatoes in a greenhousesystem|
Principles upon which greenhouse systems operate promote cultivation of high economic value crops in order to make up for the systems’ high cost. To this effect, tomatoes, peppers and eggplants have monopolized the systems leaving out other useful plants that nourish the soils. These systems therefore employ intensive use of chemicals to make up for natural regeneration of soil fertility.
One of the organic farming principles - Cyclical principle encourages collaboration with nature through the establishment and build-up of a cyclical principle that ensures versatility, diversity and harmony, and the re-cycling and use of renewable resources. It is upon this principle that conflict between the two farming systems arises; Greenhouse farmers who have attempted to go organic have reverted back to the use of chemicals after two or three seasons.
