Soil analysis should be used to decide the correct nutrient
requirements of the crop. Fertilizer programme depends on the soil type and the
fertility of the soil. For optimum nutrient levels in soil for growing
indoors, see table :
Optimum nutrient levels in soil for growing indoors(mg/l):
Here you can read all information about products I have used in the UK to get better quality produce and higher yields. ‘’Vito-1’’, ‘’Vito Calcium’’ and ’’Biomikss’’ are produced in Latvia.''Vito-1'' was used for green and white pak choi, choi sum, kai choi and kailan crop foliar feed and through the irrigation system.
''Vito Calcium'' was used mostly for green pak choi and edible chrysanthemum leaf crop foliar
feed and through the irrigation system.
''Biomikss'' wet and dry powder was used to improve soil fertility in the greenhouses for green and white pak choi, choi sum, kai choi and kailan crops.
From other countries, following products have been tried:
''Lithovit'' is an excellent natural CO2 foliar fertilizer increasing the photosynthesis of plant and supplying them by a number of micro nutrient elements. Used for kai choi crops.
''Perlka'' is a unique nitrogenous fertiliser manufactured from natural raw materials; coal, limestone and atmospheric nitrogen. Perlka composition is 19.8% nitrogen (N) 50% lime (CaO) 1.5% magnesium (MgO) The lime in Perlka in the form of calcium oxide when in contact with water this calcium quickly turns into lime hydrate Ca(OH)2 which is strongly alkaline. The lime in Perlka is therefore extremely active and positively influences the physical, chemical and biological properties of soils, as well as improving fertility. This combined with the distinctive nitrogen in Perlka helps revitalise soils which have been heavily cropped with vegetables. Allow at least 10 days between applying Perlka and seed sowing or transplanting. Used to improve soil fertility in the greenhouses for green and white pak choi, choi sum, kai choi and kailan crops.

''Maxicrop Triple'' A concentrated formulation of
seaweed extract containing 25.6% (W/W) soluble solids including 3.1:1.4:2.9 NPK
and a wide range of trace elements. Used for green and
white pak choi, choi sum, kai choi and kailan foliar feed.
