How to fertilize German Chamomile
In general, chamomile plant is not demanding in terms of fertilization. The fertilization rates are low in the average soil. However, growing commercially German Chamomile in today’s competitive landscape requires certain steps towards monitoring, improving and fixing soil nutrient deficiencies, so that our plants can give a high yield. As it happens in every other crop, there can’t be any universal fertilization scheme, because every field is different and has different needs. Performing soil analysis once a year is extremely important in order to diagnose nutrient deficiencies and take corrective actions.
German Chamomile growers often add 8-12 tons of well-rotted manure per hectare and plow well before they transplant the young plants or proceed to the direct seeding. Chamomile plant responds well to Nitrogen fertilization up to a certain level. Nitrogen deficiencies have been reported to promote root growth and inhibit stem development, something that is not desirable for an annual plant that is grown for its flower. A common fertilization scheme involves adding 120 lbs. (54 kg) (NH4)2SO4 per hectare during late winter (1 hectare = 2,47 acres = 10.000m2). In cases of severe N,P,K deficiencies, farmers often farmers apply soil fertilizer N-P-K 20-20-20 (200 lbs. or 90 kg per hectare) and plow well before transplanting or sowing.
In many cases, German Chamomile is cultivated as rotation crop between heavily fertilized plants, and in this case farmers do not apply any soil or water soluble fertilizer.
However, these are just common patterns that should not be followed without making your own research. Every field is different and has different needs. Your chamomile plants may or may not give higher yields in essential oil or dry flowers after the application of fertilizers. You can seek advice from a licensed agronomist after conducting a soil analysis.
