Alsike CloverAlsike Clover is a short-lived perennial cool-season crop lasting 2-3 years with a deep taproot and growing 24 to 36 inches tall. It does well on low, poorly drained soil and tolerates more alkalinity than most other clovers. Alsike Clover will tolerate flooding for longer periods, but it may be killed out if drought periods become prolonged. Alsike Clover is an extremely winter hardy perennial clover. A legume that is more adaptable to a variety of soil types and is extremely easy to grow in almost any condition. It is easy to establish where there is minimal soil preparation, but must be seeded shallowly. Alsike has poor shade tolerance and is intolerant to drought and high temperatures..
Crimson CloverCrimson Clover is a cool season reseeding annual legume with an erect growth habit and a shallow taproot system. It is widely used for feeding and attracting deer, turkey, rabbits and other game species to food plot areas. Crimson is a widely adapted plant that tolerates different soil types and low pH soils. It is an excellent and dependable re-seeding clover that is early maturing. Crimson performs well in mixtures with small grains or later maturing clover. When planted in the fall, Crimson Clover produces more forage at low temperatures. It thrives when planted with other grasses and is an excellent late winter grazing crop.
Durana is a cool season perennial legume, a new variety released by Pennington Seed with better yield increases will provide longer life with a more persistent stand. Intermediate clovers have a medium leaf size and a leaf density that is very thick from the ground to the top of the plant and competes aggressively with weeds and grasses. Expect this clover to live several years longer than other types in similar climatic conditions. With protein levels of 25% and digestibility of over 75%. Durana will tolerate acidic soils and is an excellent pure stand.
Dutch WhiteDutch White Clover is a slow-growing, nitrogen-fixing perennial clover used for lawns, ground cover, erosion control, cover crop, and in food plot and pasture mixtures. . It is often used to minimize soil compaction and improve soil health. Dutch White Clover usually matures between 4 to 8 inches in height. It is winter hardy, tolerates wet conditions, withstands moderate drought conditions, tolerates shade and may be used in high traffic areas, including permanent walkways and turf grass mixes. Dutch White may be frost seeded, or can be seeded in early spring and fall. Once established, it provides long-term cover and the roots fix nitrogen for companion crops.
Fixation CloverCover Crop
Fixation performs best when fall seeded. The rosette growth habit that hugs the ground assists Fixation in its ability to withstand cold temperatures. In laboratory studies Fixation survived an experiment in which clover plants were taken from 65 degrees Fahrenheit during the day and placed in a cold growth chamber overnight that was set at 5 degrees Fahrenheit. Fixation has survived winter temperatures as low as 5 degrees with no snow cover. In the early spring as temperatures begin to warm up, stems begin to elongate and quickly outgrow the weed population. In Oregon field trials, Fixation was able to outgrow and smother rogue daikon radish plants that had not winter-killed.
Fixation will aggressively produce forage in the spring – early summer months. Well established fields are capable of withstanding multiple cuttings/grazings. Fixation plants retain actively growing leaves from the tip of the stem to the rosette at the soil surface. This growth habit allows for better recovery than seen in Crimson, Arrowleaf, and other annual clovers. Fixation is capable of re-seeding if properly managed. Fields allowed to re-seed will need to have new seed applied after the third year as the populations will begin to thin. Fixation is capable of surviving water-logged soils and even short-term flooding. Fixation can be frost seeded by broadcasting on established pastures. The small seed size and hardiness of Fixation allow it to successfully be broadcast, and establish under proper management in existing forage. Recent studies in New Zealand show that Balansa clover is a better component in pasture mixes than white clover. This is because the life cycle of the Balansa clover is ending when the grass component of the pasture is becoming stressed, leaving the available moisture and nutrients for the grass. Fixation also excels in pastures because the nitrogen collected in the plant material is released annually back into the soil for the use of the grasses. Perennial clovers, such as white clover, will utilize the majority of the nitrogen that they create for their own preservation giving up little to the grasses. Fixation has a tap root structure that will delve deep into the soil, pulling up nutrients that can later be used for grasses. The deep root structure will pull moisture from below the root profile of the grasses and will not compete for limited moisture as will white clover. The root systems of the grasses make use of the rooting pathways created by Fixation and as a result can go deeper into the soil profile increasing the summer performance of the grasses. The high forage quality of Balansa clover also makes it an excellent choice for over-seeding/ frost-seeding into alfalfa hay fields. The clover will thrive were the alfalfa is likely to succumb, filling in wet areas and other bare spots and thereby improving yields and quality.
Fixation Varietal Background
Grassland Oregon has been investigating the potential of annual clovers for both a forage and nitrogen source. Escalating fertilizer prices as well as an increased interest in the utilization of cover crops in the Midwestern United States led us to believe that there would be a demand for a forage/nitrogen fixing legume that could fill that particular need. Fixation is the result of our efforts. Fixation matures approximately 14 days later than Dixie Crimson Clover and as much as 28 days later than other commercially available Balansa varieties. Despite being later in maturity, overall growth is greater than that of the earlier maturing Balansa clover varieties throughout the growing cycle. The later maturity allows for multiple cuttings/grazing and reduces the likelihood of unwanted re-seeding. Fully developed plants exhibit excellent re-growth, and recover more rapidly than other clovers. Forage yield is quite impressive, yielding as much as 5,250 lbs of extremely digestible dry matter in a single cutting. Plants are able to support growth up to 3 feet high with stems as long as 8 feet long. Crude protein levels range from 22% to 28.4% with relative feed values measured as high as 277.
