12 Plant nutrition - visual soil assessment

PLANT NUTRITION - SYMPTOMS OF NUTRIENT DEFICIENCIES, CHLOROSIS, DISCOLOURATION When the crop is under nutritional stress or under any type of stress, it is common to find discolouration: chlorosis, yellowing on the leaves, etc. When no chlorosis is observed and the crop is intense green in an active plant growing phase, this means that the plant is developing properly and the condition is good, as in this case. In other situations, we can find partial yellowing or severe yellowing of the crops. If the yellowing or loss of colour is severe, the assessment will be poor. EXAMPLE OF PARTIAL YELLOWING DUE TO LACK OF NITROGEN EXAMPLE OF PURPLE COLOURING DUE TO LACK OF PHOSPHOROUS With intermediate discolouring, or occurring in a crop area but not in other areas, the score will be intermediate. In our case, there is a good colour so this is a good score.
