Here is what to do to end the erosion and build soil life.

SLIDE 9

Direct Seeding on 50% + Slope

SLIDE 10

Cross Slot Drill Seeding Chem Fallow

SLIDE 11

What changes have occurred with 40 years of continuous Direct Seeding?

1. Soil wind and water erosion for us is now a non-issue.

Rainfall is absorbed and stored for the crop.

2. Residues left on top of the ground control all wind and

water erosion. Soil is now alive with microbial communities which feed on the residue.

3. Our natural prairie OM is 1 ½ - 4 ½%. Most OM

measurements on the land after decades of no-till is now 3 ½ - 5% and still moving up.

Seeding into stubble

SLIDE 13

Snow drift and standing residue through the winter, residue helps prevent ditches and erosion

SLIDE 14

Food Quality is a Function of Soil Quality

SLIDE 15

Water infiltration and rain simulator

SLIDE 16

Soil pit and worm castings

SLIDE 17

Soil clod

SLIDE 18

We are now with improved and modified Direct Seed equipment able to successfully crop some very sloped fields with no erosion, due to the high amount of residue left in the field and the changes that have occurred in the soil profile due to Direct Seeding.

Paired (Twin) Row Wheat with Residue

SLIDE 23

Cover Crops build soil life and change the rhizosphere to accept and hold inches of extra moisture instead of running off.

Wild life has truly increased due to more feed and cover and less human activity due to no tillage!
