Figure 1 – early bud development in blueberries<\/p><\/div>\n
Blueberries are currently breaking dormancy and first flowers are present at early sites. It is likely that where tunnel skins have been removed the substrate has been flushed with rain water and therefore the feed in the pots is relatively low.\u00a0 Consequently, it is time to begin blueberry feeding now that the top growth has started moving.<\/p>\n
OMEX can supply two specialised blueberry feed mixes of either O-Mix<\/strong> 18-18-18+1.6MgO+TE or O-Mix<\/strong> 15-15-22.5+1.6MgO+TE (see table for specific nutrient inclusion).\u00a0 Both deliver high quality soluble nutrition and contain a greater N-P-K content than similar blueberry feeds on the market. Hence, there is less reason to supplement the blended feed with additional \u201cstraight\u201d water soluble fertilisers.<\/p>\n Due to low ambient temperatures, it can be difficult to feed the blueberry crop as often as desired for fear of \u00a0quickly saturating the substrate with too many fertigation cycles.<\/p>\n Under these circumstances, applications of Sulphomex<\/strong><\/a> can deliver fine particles of ammonium and sulphur to the bush supporting early season protein synthesis.\u00a0 As the slide below shows, mixing elemental sulphur and applying it to the canopy is likely to leave sulphur deposits on the foliage, increasing the chances of a phytotoxic reaction by the plant. Sulphomex<\/a> applications in comparison, do not leave a deposit on the leaf and can be combined with a number of plant protection products, the compatibility of which can be checked<\/a>.<\/p>\n
