[QUOTE="ollie989898, post: 7629235, member: 54866"] A maize fertiliser plan? All sounds a bit technical to me. Soil test. Apply what is needed in the seed bed, use a decent starter fertiliser (these are all invariably based around DAP or MAP) and be done with it. I would agree that some fields/farms may need to add N + K and probably sulphur alongside the starter they use but certainly not all and certainly not every year. I've had farmers try various combinations of starter fertilisers, varying amounts of nitrogen applied by fertiliser spreader post-em, various liquid or suspension products applied by sprayer never came to the conclusion people were getting better or worse crops than anyone else. There is definitely a place in my view for foliar phosphate/manganese/magnesium products where a crop is showing signs of them but applying these to big areas routinely is going to get expensive fast. What maize wants is good hot weather. If you had a maize crop with a genuine deficiency of nitrogen or potash you would definitely know about it very soon after emergence. I've seen these in the USA but I've only ever seen a few isolated patches of it in the UK. Biggest problem around here is compaction, slumped soils or waterlogging. Good seed bed and rotation is worth investing more time in than spraying on micronutrients. [/QUOTE]
