USDA researcher predicts 100%
WASHINGTON, D.C. - A U.S.
Department of Agriculture
research administrator predicts
the virtually all U.S. cropland wUI
be farmed under some form of
conservation tillage by the end of
this century.
That prediction comes from
Terry B. Kinney, administrator of
USDA’s Agricultural Research
Service, who says in the March
issue of Agricultural Research:
“Conservation or minimum tillage
decidedly is coming of age as
scientists, advisors, and farmers
smooth out the rough edges on a
farm practice that can do more to
preserve this Nation’s soil and
water heritage than any other
single practice.
‘ ‘We should set a goal of applying
no-till or ridge till - some form of
conservation tillage - on every
suitable acre of U.S. cropland by
the end of the century. I predict
this Nation’s agricultural com
munity will achieve that goal.

For Heavy Stubble and Hard Soils
The new Liiliston 9680 No-Till Grain Drill will
operate in maximum severe conditions, where
uniform penetration of heavy stubbie and hard
soils is required. Unlike some of the so-called
" no-till" drills available today, which are actually
conventional drills with front coulters added, the
Liiliston is designed, from the ground up, for one
purpose; No-till seeding.
Some Special Features
O Maximum empty weight of 7,160 lbs. transfers 390 lbs. of down
pressure to each of the 18 openers on 7 inch spacings.
% Heavy duty 14 inch cutting coulters and double disc openers,
spring-loaded scrapers and center rib gauge wheels.
9 Three hydraulic cylinders regulate pressure on openers for
precision depth control.
4P Patented double-chambered feed cups which maintain even
seed flow to the feed wheels.
% Cluster gear boxes for easy selection of 27 application speeds
of seed and fertilizer.

“most farmers wouldn’t hear of
tillage methods that left residue on
the top of the soil. Hiey opted for
clean plowing, turning all crop
residue undere with moldboard
and disk plows, a practice that
produces maximum rates of
erosion.
“Now the Department’s Soil
Conservation Service (SOS) says
that about 100 million acres, nearly
a fourth of U.S. cropland, is
minimum tilled or not tilled in
cropping systems. ’ ’
Kinney says the upsurge in
farmer interest in stimulated
largely by reduced fuel and labor
costs, but also by research
progress, education, and farmer
experience. “Farmers are
deomonstrating for themselves
and others that minimum or no-till
practices do improve soil and
water conservation while main
taining, even increasing, crop
yields where implemented
properly.”
