[QUOTE="Kiwi Pete, post: 6820315, member: 63856"] Sunflowers, oats, peas, beans, radish? All of these will outcompete PP most of the year especially during the cool season, and scavenge P+K from well below the existing rootzone. Seem to withstand slug pressure pretty well too. The main caveat with this type of approach is that soils high in aluminium (for example NZ volcanic soils that have been hammered with TSP) will not allow good rooting to depth. Roots hit this chemical "pan" and go sideways, and leafier species like lucerne/chicory can simply wither without good rooting if it goes dry (maybe not much concern where you are)? Thus, more powerful types of plants like radish and sunflower tend to prove more effective in these situations. Some parts of NZ have such high levels of heavy metals and aluminium from superphosphate use that their only salvation lies in forestry, the only cure is silica + time, which trees provide. [/QUOTE]
