After transplanting offspring of these ecotypes into the harsh environment of the Department of Animal and Dairy Science's Beef Research Unit near Eatonton, Georgia, plants were subjected to heavy, continuous grazing with grass competition. After clover establishment, it generally needs approximately 30 inches of rain a year to be productive and 45 inches or more is optimum. Division of Agriculture and Natural Resources Freezing forms a "honeycomb" appearance on the soil and allows legume seeds to settle just below the surface after several freeze-thaw cycles. 6. Nat. When first planted, water daily to speed germination and help establish a strong root system. Durana flowers profusely for long periods, which may make it a more dependable reseeder. Every day, give the seeds a little sprinkle of water until they grow leaves. Oakland: Calif. Agric. 2,4-D has only a short residual activity (two to three weeks) and should not pose many problems, but dicamba (Banvel or Weedmaster) has a 120 day residual activity and picloram (Grazon P+D) has residual activity up to one year after spraying. All rights reserved. When is the best time to plant clover? Aside from determining soil pH, a testing kit also identifies mineral and nutrient deficiencies in your soil. In contrast, white clover is seldom found in ungrazed pastures or hay fields that are cut infrequently. Flowering period and leaf size fall between small and large-type white clovers. If pastures are continuously grazed, monitor stocking rates closely. and thus more aggressive.

Many homeowners add clover to an existing lawn. Choose a productive and persistent white clover variety. Berseem produces up to 1,000 lb. Soil acidity influences availability of several nutrients and decreases survival of Rhizobium bacteria, which are necessary for nitrogen fixation. So, with this cold spring, you are probably well below those numbers. Understanding seed germination at different temperatures is necessary for reclamation practices utilizing prairie clovers, and also to develop potential rejuvenation protocols for the threatened hairy prairie clover. The best herbicide to use depends upon the species of turfgrass. For instance, adjust the fertilizer program to include more nitrogen and less phosphorus in turfgrass. Finally, it is not surprising that more farmers are rediscovering the benefits of using clover leys. Unfortunately, they dont reseed very well, especially compared to other annuals. Once established, encourage more growth by mowing regularly. There are many animal and agronomic related reasons for establishing a productive stand of white clover in existing grass pastures. Soil should be limed to a minimum pH of 6.0. A concentration of 1.0C to 48.0C was used to assess the vigor and growth of the plants. Crimson clover plants prefer cool climates and will die back in extreme heat or cold. If fewer than five live plants per square foot remain following a freeze, consider interseeding forage grasses or rotating to another crop in that field. Sowing rates of spring cereal should be reduced by one third otherwise the undersown ley may be smothered. When clover seeds are allowed to dry out, their germination time is slowed down or they do not germinate at all. 6. Clover. Once the white clover runners have rooted, it is safe to graze. Establishing Clover LeysFor sound establishment, a well cultivated, firm and level seedbed is essential. It is important to note that clovers should never be fertilized with nitrogen. For more information on Oxalis species, see Pest Notes: Creeping In general, you can choose from two kinds of clover: annual and perennial. White clover performs well on wet soils and persists far better on these soils than red clover. To germinate, clover seed needs a soil temperature in excess of 6 degrees centigrade.

When the soil temperature rises in the spring, the seed will germinate and begin the growing process. Clover grows readily from seed. Soil test pastures on alternate years and apply necessary lime, phosphate (P) and potassium (K) to maintain healthy and productive stands. After one year of grazing, basal coverage of Regal ladino clover was significantly less than that of Durana or Patriot. Lower optimum temperatures of seed germination for Hamedan, Malayer and Isfahan varieties were 12.53, 12.75 and 13.45C, while upper optimum temperatures were 25.00, 32.81 and 33.56C, respectively. Strawberry clover Trifolium fragiferum flowers and leaves. As such, your best bet is to plant annual clover seeds in areas where winters are considered mild.
