Mexican Sunflower is fast growing, not fast enough here because we would like to use it extensively as soil conditioner and fertilizer. It is a weed and invasive species that originated from Central America.
- High in Pottasium (low in Mg). As fertilizer contains 1.76% N, 0.82% P, and 3.92% K.
In comparison cattle manure 0.6% N 0.4% P 0.5% K
Giliricidia 3.26% N 0.41% P 2.76% K
- Soil conditioner, i.e. loosens soil.
Much needed here because of clayey soil that becomes like rock when dry and prevents root growth.
- Decomposes fast, so nutrients available quickly.
That means can be used for short duration crops such as vegetables.
- Grows from plant cuttings. i.e. easily propagated.
The plant cuttings seem to be tolerant of hard water (High Mg, Ca).
- Attracts Butterflies and Bees (a big plus).
- Beautiful Flowers
