LANCASTER Last summer’s
dry, hot weather hurt crop yields
over much of the nation It was the
worst growing season in six years,
according to USDA
The yield estimate for corn in
1980 was about 91 bu/A, down from
109 bu/A in 1979 Even so this
makes it the sixth best year for
corn on record not bad for such a
poor growing season
How does good soil fertility help

How fertilizer stretches moisture
stretch available water into more
bushels’
Adequate fertility stimulates
deeper root growth and ex
ploration of the soil This makes
more soil water available to the
plant
Adequate fertility speeds
maturity. It is very important for
corn pollination to occur before
summer drouth hits. On an Illinois
soil high in K, corn receiving no

Adequate fertility reduces the
crop’s water requirement
Potassium reduces water loss in
plants by lowering transpiration
rate and aiding the closing of
stomates (pores where plants
expel water).
Adequate fertility compensates
for lower nutrient uptake Such

nutrients as N, P, and K need to be
swept into plants along with the
water Drouth can damage crops
worse when nutrient uptake is
reduced. A higher fertility level
allows more nutrients to be taken
up by a water-stressed crop to help
lessen the yield loss
Crops often respond to fertilizer
as well or even better in dry years
than in normal years.
In Ohio, the first year had ample
rain Yields were high (160+
bushel, but there was no response
to potash The second year was
dry. Yields were down (120 to 130
bushel). But there was a 50 bushel
response to K.
In Virginia, corn yielded much
better in good years than bad
years But phosphorus increased
yields about the same in both 40
bushel an acre in good, 37 bushel
an acre in bad years.
In another Virginia study, high
fertility more than doubled in the
yield in a poor year from 53 to
111 bushel an acre High fertility
also gave an excellent increase in a
good year 127 to 205 bushel an
acre.

reduced by too little or too much
ram, fertilizer gave the greatest
response Potassium increased
yield 39 bushel an acre in low
rainfall, eight bushel an acre in
medium rainfall, and 48 bushel an
acre in high rainfall
A main force behind today’s
higher yields is nitrogen. Still more
nitrogen will be necessary for
tomorrow’s even higher yields,
squeezing more bushels from
every inch of water
Gram sorghum m Texas needed
240 lbs per acre of N for the
highest yield and for the greatest
amount of gram per inch of water
Without N grain sorghum
produced 45 hundredweight per
acre and 1.9 hundredweight per
mch of water. With 240 pounds per
acre of N, gram sorghum produced
73 hundredweight per acre and 3.5
hundredweight per mch of water.
Fanners get deeper rooting
through a healthy, well nourished
plant. It has a deeper rooting
system that can extract more
water from greater depths m the
soil profile
