Fine granular Zn-sulfate is available, and 3 to 5 lb/acre Zn could be applied through granular herbicide applicators prior to seeding with more immediate results. The first trial took place at Indian Head (IHARF) and Melfort (NARF) in 2013 and involved Vitaflo. Schlegel, ed. Because yield increase seldom is achieved through the application of P, no P fertilizer is recommended directly to flax. Today, growers in Canada and the United States grow seed flax varieties. “At our two locations, we saw a significant increase in plant populations, so we had improved crop establishment. Flax can show good response to fertilizer N when soil N is low. 1978. If you know that your soil conditions can cause zinc chlorosis, consider soil testing and the use of fall applications of zinc. The netting-like filaments are mycorrhizae hyphae. Growers who insist on applying fertilizer with the seed should limit the application to maximum N levels with the seed, as shown in Table 2. Flax is a moderate user of both K and S nutrients. K deficiency is unlikely to occur in clay-textured soils, but could be an issue in sandier soils. Incorporating N fertilizer can be a time saver, but environmental loss is the trade-off. They are available in the form of manures, compost, and granular or liquid amendments.Most often we apply them to a plant’s root system or as a foliar spray. Other options for potassium sources include potassium sulfate, or a liquid fertilizer derived from potassium hydroxide. Fertilizers are any naturally or chemically derived material containing the nutrients essential for plant growth. Half of the N credit indicated for the first year for sweet clover and alfalfa is recommended, but no N credit is recommended after the second year for other crops.

Prevention of iron chlorosis may be achieved by better drainage. Mycorrhizae hyphae (small rootlike structures, Figure 2) explore the soil within a couple of feet of the host plant and are very good at mobilizing P from the soil and transferring it to the host. Lift and divide plants in the spring. Some provinces recommend that a low rate of phosphate may be placed with the seed; not more than 17 kg/ha (15 lb./acre) of P 2 O 5. Soil testing prior to applying N fertilizer is highly recommended, as flax can be limited by both insufficient and excess N. Studies show that N deficiency can reduce the production of tillers, fruiting branches and capsules produced per plant, while excess N can increase the incidence of lodging and delay maturity. Basic all purpose fertilizer . Application of some sources of unnecessary P fertilizer with flax may increase seed cadmium concentration. Iron chlorosis often is confused with Zn deficiency, and sometimes they appear together.

Yield and N rate are not related across locations, so the N rate of 80 pounds (lb) N/acre is valid for high-yielding fields and fields with lower productivity. Canadian Fertilizer Institute. Moreover, flax fibers are used to make linen. Later in the season, the plants may sprout new shoots from lower nodes and form a candelabra appearance; maturity may be delayed. Everything you need to know about flax in an easy-to-find news format. As well, N will be subject to losses to the environment, through denitrification and leaching. Foliar applications of iron are seldom effective in increasing yield, although they may green up the crop. Today, growers in Canada and the U.S. grow seed flax varieties. There is very little work on differences in fertilizer P sources on flax yield, but similar to nitrogen fertilizers, P fertilizers can also cause seed damage when placed in the row.
