Nitrogen, Phosphorus, Potassium, Calcium, Magnesium, and Zinc in Southeastern USA Harvested Flax

Crop, Forage & Turfgrass Management, 2015
Flax (Linum usitatissimum L.) is a winter crop in the southeastern United States that has potential in double cropping systems. This research was conducted to provide estimates of N, P, K, Ca, Mg, and Zn removal in the harvested portions of the crop (straw and grain).

INVESTIGATION OF THE PROCESS OF FLATTENING STEMS DURING FLAX HARVESTING

Tractors and Agricultural Machinery
BACKGROUND. When preparing flax straw using the dew retting method, uniformity of the raw material’s technological parameters along the length of the stems is not ensured, which reduces the yield and quality of the fiber.
