I am not a farmer, just a home gardener. But I like to watch Ag PhD because of all the info they gave us, it certainly helped me in my gardening knowledge.

Hi, Im from Mexico and I anderstand just a few what you guy said but it is good becouse you explain what we must do very well, thanks

I love how these guys cut eachother off and bicker hahaha sounds like a great relationship

Excellent information, of interest for everyone from the large farmer to the small farmer to the market gardener.

you guys rock thanks for sharing

It takes 100000 lbs per acre of dry matter to raise OM from 2% to 3%. Considering that OM is also breaking down, it could take a lifetime to slightly build OM levels

Great material, guys! I heard you reference 3% in a lifetime for improvement in organic matter. Can a farmer ever do significantly better than this?

Only maiz production

Very good

I'm farmar

5:20 "where organic matter get's built from predominatley is roots breaking down in the soil." This is not correct. The buildup of organic matter next to roots is a combination of bacteria, fungi and root exudates. The roots exude organic materials to feed the bacteria and fungi. In exchange, the fungi and bacteria supply trace minerals to the plants. The plants will become healthier as the soils increase microbial life and become more fungal dominent. The fungi and bacteria also protect the plants from pathogens and allow for greater photosynthesis. The higher photosynthesis improves Brix levels which inhibits predation. The higher soil biology not only improves water holding capacity but allows for gas exchange at lower depths enabling roots to grow deeper. This process is the only truly effective way to eliminate soil compaction. Some prairie grasses can grow roots to over 40' in depth. The annual forbes you are calling weeds thrive in bacterial dominent soils. As you improve the organic matter, you will inprove the levels of fungi which will naturally inhibit the growth of annual forbes.
