No-till drill
The John Deere 1850 no-till drill is designed for seeding into no-till, mulch-till and conventional-till conditions.
The 1850 uses proven openers from the 750 no-till drill mounted at 7.5- or 10-inch (19 or 25 centimetre) row spacings on a two-rank, three-section, overcentre folding frame. Working widths are 9.2, 11 and 13 metres.
When teamed with the 787 air seeding system, the 1850 can seed a large number of acres in a range of soil conditions.
Tanks range in size from 130, 170 or 230 bushels and are divided into pressurized compartments (40-60 split) to allow fertilizer application while seeding. Seed for a variety of crops can be metered, including wheat, barley, oats, canola, flax, soybeans, peas and lentils.

Active hydraulic down pressure provides up to 200 kilograms (450 pounds) of pressure per opener to penetrate hard soils and heavy residue. When connected to live hydraulics, the system automatically maintains uniform down pressure on the openers as field conditions change.
Wings flex 20 degrees up and 10 degrees down to maintain seeding depth over uneven terrain. A floating hitch allows for consistent seeding depth from front-to-back by providing a pivot point between the towing vehicle and the seeding tool.

Detect late blight
The Alert On-site disease detection kit allows potato farmers to bring the laboratory to the field, allowing timely and accurate identification of late blight.
The kit can be used to test suspected seed lots for phytophthora infestans, reducing the risk of planting infected seed; to test alternate hosts of late blight which may be present in surrounding fields; to check cull piles which may be harboring the disease; to test actual potato foliage, confirming the presence or absence of the disease; to spot test potatoes going into storage for the disease, enabling producers to ship infected bins first.
A plant sample is ground up and taken through five steps that indicate whether phtyophthora infestans is present. It takes 10 minutes to yield a positive or negative test. The test allows growers to identify the disease before symptoms can be seen.
The kits are also available with the AgriMeter II, a recording unit that reads and identifies the level of infection.
