NATURAL ORGANIC FERTILIZER
ECO FRIENDLY PLANT NUTRITION
Soil
fertility is dependant upon the continued replenishment of nutrients and
organic matter that is depleted each cropping season. Soil requires more than NPK (Nitrogen, Phosphorous and Potassium)
to maintain fertility, it must be capable of storing nutrients
and transferring these nutrients to the root surface for uptake by the plant.
Unhealthy
plants result from unhealthy soil.
Perhaps the most
depleted component in our soil is humus, (decomposed organic matter). Geological
humus is produced as dead plant and animal material is metabolized by
soil microbes.
Organic matter cannot be built up permanently because it
continually decomposes. Soil building must be an on going process.
To ensure continued soil fertility,
organic matter, in the form of green manure, compost,
crop residues and similar materials should be incorporated into
the soil after harvest
