• Crop rotation, as a rule, can improve the performances of all crops. Tomato belongs to nightshade (Solanaceous) family, like pepper, potatoes, tobacco, and other plants: so, turning with such crops should be “long” because some diseases are common among these plants (Phytophtora for example). Tomato should not be grown on the same field within the period of 4 or, better, 5 years in order to avoid the building up of pathogens
• Crop Rotations allow the farmer to spread labor intensive operations out throughout the whole season, reducing labor and equipment requirements peaks.
• Exploitation of soil fertility is improved, because different crops roots explore different horizons of soil and utilize nutrients at different rates. For example, Soybean enriches the content of N in soil for following crops and Alfalfa moves nutrients from deep horizons of soil to shallower layers.
• Structure of soils improves because residues from crop roots stay and decay at different depths and crop residues have different nutritional contents.
• Management of pests and diseases gets easier because different crops have different pests: crop rotation is a powerful mean to avoid or reduce damages.
• Management of weeds also get easier for the same reason: for example, control of monocot weeds (grasses) is much more easy in tomato than in monocot crop as cereals or corn.
