[QUOTE="Thedual1, post: 2027878, member: 16806"] Calcifert S would be a good option for raising calcium, you will also strip out some of the magnesium with this. I would be looking at applying a good magnesium foliar spray at each spray application as you have high soil magnesium levels, which may not be plant available. A simple test is if you spray foliar magnesium be it liquid or Epsotop to cereal crops on high mag soils they will green up, showing that the soil magnesium is not plant available. Magnesium is a very important nutrient in chlorophyll and photosynthesis and plays a massive part in grain size and weight Another thing to watch is if you apply high levels of calcium you will antagonise both phosphate and boron, and as such you should be looking at applying both foliar phosphite and foliar boron. Calcifert S is also high in sulphur which may antagonise the soils copper as such you should back up with foliar copper. I love soil nutrition it is all about balance, understand Mulder's chart and you will be well on your way to getting soil in balance. [/QUOTE]
