AGRICULTURAL FARMING REQUIREMENTS Hectares needed to be financially viable: With 0.5 hectare of land, small producers can aim at high quality, value added markets for essential oil and flower production to get the most profit from lavenĀ­der farming. Yield per hectare: True Lavender yields 8 to 30kg, Lavandin 40 to 220 kg essen- tial oil. Most suitable cultivars: English Lavender, Lavandin and Spika. Climate Requirements: Lavender toleĀ­ rates moderate frost and drought and requires full sun, with 300-1400 mm of rain per year. Soil requirements: Well-drained, light, sandy soil, pH should be between 5.8 and 8.3 and have low fertility. Soil preparation: Organic soil prepara- tion practices are encouraged. Plant on raised beds. Irrigation: Irrigation is needed for the first one to two years until the crop is stable. Plants must not be water stressed at flower initiation. Irrigation may increase production in mature plantings. Overhead irrigation will increase disease problems and will cause older plants to break open in the middle. Drip irrigation is recom- mended as it will also assist with weed control. Fertilisation: Lavender needs little to no fertilisation. Lavender is famous for grow- ing well in low nutrient soil. However, commercial organic lavender growers often add 8-10 tons of well-rotted manure per hectare well before they transplant the young plants. Then, every 2-3 years, they add 5-6 tons of manure per hectare, most often during the autumn. They cultivate carefully so that they will not hurt the roots and irrigate well after every manure application, if there are no autumn rainfalls. Slow release organic fertilisers are also commonly used. SENWES SCENARIO | AUTUMN 2018 15
