General Nutrient Principles
  1. soil supply + fert
    1. plant nutrient requirement
    2. crop requirement - soil supply
      1. fert required
      2. potential yield x nutrient content
        1. crop requirement
        2. 80% of OSR received sulphur last year
          1. E-on state that desulphurisation towers reduce SO2 emissions by 92%
            1. hence reduce natural soil levels
          2. RB209 not enforced but states best practice
            1. assess crop requirements
              1. assess nutrient supply from soil
                1. every 4 years
                  1. SNS annually
                    1. allow for nutrients from FYM
                    2. only apply what is needed
                      1. ensure nutrient losses are minimised
                        1. lost profit
                          1. more pollution
                          2. difference between maximum and optimum
                            1. FACTS
                              1. learn RB209
                                1. FQA - professionally liable
                                2. sustainable use directive
                                  1. Fert use survey every march
                                    1. British Survey of Fertiliser practice 2011
                                      1. Approx 100kg/ha of N
                                        1. N use in grass has decreased
                                          1. economic
                                            1. more efficient
                                              1. area reduction
                                                1. increase in manure use
                                              2. P and K decrease
                                                1. on grassland and arable
