New Zealand foresters have turned to California species, particularly the Monterey pine, to reforest large areas for timber production, erosion control, and “agro-forestry.”

Applying NAA to olive trees about two weeks after full bloom proved easier and more reliable than timing thinning sprays by fruit size alone. The key is recognizing full bloom.

Three theories are offered for illegal immigration-unemployment at home combined with demand for cheap labor here; ease of migration; and rapid assimilation into U. S. society.

Damsel bugs consume large numbers of insect pests in hay alfalfa in the Sacramento Valley but need the help of other beneficial insects to provide effective control. Border or strip cutting is recommended.

Rapidly resprouting eucalyptus, harvested twice annually, produced fuel for downdraft gasifiers at lower cost than is possible with most annual crops. Yields were up to 22 tonnes per hectare per year.

Many western San Joaquin Valley basins contain naturally high-nitrate soils that may cause problems, especially when used for irrigated agriculture when nitrogen fertilizer is added.

A new “glance” technique permits one person to spot-check several milkers and cow-flow patterns at once, providing data that may help improve milking parlor design and worker training.
