B) Prior to planting, seeds may be dusted with fungicide to insure seedlings become established.
C) Soil moisture is monitored and the fields irrigated when needed.
D) Soil or the seeds to be planted may be augmented with beneficial soil bacteria to insure good plant nutrition.
E) Harvesting of seeds for commercial purposes are done at the same time and with the same equipment used for to harvest non-commercial crops.
