[QUOTE="Warnesworth, post: 1555608, member: 3357"] Which ever way you look at it, it's a large amount of sodium, and twice the amount of Nitrogen the average wheat crop receives. Does the crop or the soil need this. No. Sodium is excellent at dispersing the clay platelets in the soil, the soil structure collapses causing anaerobic conditions very quickly. This is not helpful to crops and soil fauna (except the anaerobic bacteria). RB209 gives a recommendation of 200kg/ha of Na2O for beet on an K index 0 soil. This is the largest amount recommended for a very responsive crop. This equates to ~150 kg of Sodium. One third of the amount applied above! How do you get around the EA deployment caviat of 'disposal' against 'recycling' as applying this much sodium surely constitutes disposal? [/QUOTE]
