1/8 Soil requirements for tomatoes. A very high level of soil fertility is required for the profitable production of a successful tomato crop. The quality and quantity of tomato fruits are of crucial importance and are greatly influenced by the fertility and nutrient levels of
2/8 the soil. Tomatoes will grow moderately well over a wide range of soil types. However certain criteria have to be satisfied in terms of the soil structure and content to make it commercially viable. These factors include: Nutrient composition, Compaction, Effective soil depth
3/8 pH, Crop rotation, Herbicide residues, Water holding capacity. All these factors can have major influences on the resulting yield. The soil must permit adequate root growth to support the plant and supply water, oxygen and mineral nutrients and must be free of toxic elements.
4/8 The rate of root growth is dependent on the degree of compaction or bulk density of the soil. The degree of soil compaction varies with soil type and location. The rate of aerial and root growth of tomato plants increases with the oxygen contents of the soil. Root density is
5/8 highest where there is a high rate of diffusion. Root development of tomato plants can be extensive if soil water and plant conditions are optimal. They can be as deep as 1.5m and as wide as plant spacing will allow. Early root development should be encouraged because nearly
6/8 all root growth occurs before fruit set. The importance of organic matter cannot be over emphasized. Organic matter in the form of decayed leaves, compost, sawdust or animal manure is a source of plant nutrients and acts as a soil conditioner. It increases the capacity of the
7/8 soil to retain water and nutrients. It also promotes root growth and the infiltration of water and air into the soil. Tomatoes are sensitive to cold and should not be stored below 13°C. The taste of a tomato will not improve once refrigerated. Tomatoes are sensitive to
8/8 ethylene (ripening hormone) and should not be stored with fruit that produce ethylene such as bananas, avocados and Kiwi fruit.
