Organic fertilizers should by no means be used for chamomile, as the limits of microbial contamination could easily be exceeded. Organic fertilizers may only be used for the anticipated fruit.

With extensive cultivation the recommendations for fertilization based on Nmin values ascertained are the basis for the determination of fertilizer requirements pertaining to the fields. The deprivation of nutrients has become the basis of fertilization to an increasing extent [65, 72]. (See Table 5.2.3.)

5.2.3 Harvest

Even though chamomile is cultivated throughout the world, the collection from wild populations, particularly in central, eastern, and southern Europe, Greece, and Turkey has not lost its importance. There is a difference between "pure wild collection" as in Greece and Turkey and the organized harvest of wild populations, as is the case in Hungary for about 95% of the whole harvested quantity. From such wild collections or small cultivations and in gardens, chamomile is harvested at the period of full flowering, i.e., when most flowers are already open. Today, cultivation areas are mainly harvested automatically, although partly manual harvesting is still being practiced as well.

The harvest schedule plays an important role with regard to the quality of the product. Harvest of cultivated chamomile should be realized in the same way as for wild populations, i.e., when the major part of the flowering heads has already opened. The essential oil content of inflorescence
