A positive linear correlation was found between effective recombination rate and annual precipitation.

The annual precipitation of rain and snow determines primarily the location of dry-farm areas.

When the annual precipitation is under 20 inches, the methods of dry-farming are usually indispensable.

LIMA Rain in the Peruvian capital is almost non-existent, with average annual precipitation of 7 millimeters.

The rainfall is very scant the average annual precipitation at Yuma being less than three inches.

The total annual precipitation is directly influenced by the land topography, especially by the great mountain ranges.

Rainfall patterns are set to change, with annual precipitation, humidity and cloud cover predicted to decrease over most of Australia.

Municipalities with lower human development index, less access to of potable water, and with higher annual precipitation showed higher STH prevalences.

The areas of these, as given by the Census of 1900, grouped according to the annual precipitation received, are shown below:-

The dry-farm district of Brazil receives an annual precipitation of about twenty-five inches, but irregularly distributed and under a tropical sun.

The Transvaal has an average annual precipitation of twenty-three inches, with a large district that receives between thirteen and twenty inches.

Locate the dry-farm in a section with an annual precipitation of more than ten inches and, if possible, with small wind movement.

Average annual precipitation was 323 millimeters in the 1970s; between 2008 and 2008 the average was 279 mm.

The fundamental operations of dry-farming include a soil treatment which enables the largest possible proportion of the annual precipitation to be stored in the soil.

In the subjoined table, constructed on the basis of the discussion of this chapter, the wheat-producing powers of various degrees of annual precipitation are shown:-

With an annual precipitation of 10 to 15 inches, there need be very few failures, if proper cultural precautions are taken.
