The main areas discussed in this presentation were the water cycle, soil fertility and crop establishment, and methods developed by Harry Whittington, a Brookton farmer. If necessary, plastic sheeting is put beneath the clay-soil to retain the water. Humus is important in the water cycle to help soak up moisture. Green manure crops, such as lupin and barley, are planted between December and February, not too soon.
Much time is necessary to observe and examine the soil.
However, if there are weeds they can be grazed. There is usually a three year rotation. Plough in the weeds after germination, apply the rock minerals, then seed. Harrow the weeds if necessary, then harvest. On leaving Agricultural College and returning to the family farm, Peter became interested in water control.
