CLIMATIC DATA
GENERAL

Table 1 gives the daily precipitation for 1952 as recorded at the Dickinson Experiment Station for the U.S. Weather Bureau.

Table 2 is a climatic data summary of precipitation, temperature, wind velocity, evaporation and frost free period for 1952.

Above average precipitation in September and October of 1951 plus slightly above normal snowfall in January, February and March of 1952 provided enough moisture for germination and early crop growth. April of 1952 was the first April in the past 60 years to have no measurable amount of precipitation fall, and this, followed by only .42" in May, a month having a 60 year normal of 2.24" resulted in considerable damage to the small grains and grasses during this critical growing period. June Rainfall of 3.80" coming at well spaced intervals and in quantities great enough to penetrate the soil to some depth helped to revive the grain crops and improved the outlook considerably. Rainfall for July was slightly below par with only two rains during the month, one of .74" and one of .37" coming in effective quantity. Excellent August moisture and delay of the first fall frost aided in producing a fairly good crop of corn.

Soil moisture was depleted at the end of the growing season of 1952 and moisture conditions will need to be very favorable in the spring of 1953 to promote good germination and start the crop.
