Prevent Plant? Maintain Soil Health with These Useful Tips

When fields are open during late spring/summer, whether part of a planned system or created by unfortunate weather, it’s critical to keep soils covered, taking advantage of the longer seeding window and maintaining soil health benefits.

Keep these items in mind if prevent plant is a possibility within your operation:

1. DO SOMETHING. Leaving ground fallow greatly increases risk of erosion and improves the likelihood of leaching nitrates, sulfates and other nutrients that could be used by the following year’s crop. Bare ground also encourages risk of “Fallow Syndrome” the following year. Fallow Syndrome occurs when there’s no plant growth in an area for an extended period. Populations of “good fungi”, called active mycorrhizae, are reduced because they need actively growing roots to survive. These fungi depend on host plants to complete their life cycle. Adding a grass (ryegrass, oats, etc.) or legume such as peas or hairy vetch are extremely beneficial and will better support the good fungi in the soil.

2. DETERMINE YOUR GOALS. There are many “cover crop” options available to use. The crop rotation goals of the producer should help steer the decision. Normally, crop harvest can often limit the time we have available to plant a cover crop, but because our planting window is now early, just about everything can be considered. Again, this should depend on what the producer wants to accomplish with the cover crop planting.

3. UNDERSTAND THE GUIDELINES.If taking the full prevented plant option, haying or grazing is not allowed until after Nov. 1 (or other dates in the Midwest, depending on state or region). Check with your state or county FSA office for further info on grazing restrictions with this program.

 

4. THINK ABOUT HERBICIDE RESTRICTIONS. Consider herbicides already applied on acres not yet planted. In many cases, cover crops and other non-traditional crops will not be listed on the herbicide label. Many universities are doing more work on this topic to determine what options farmers have in the case of “prevent plant” or other cropping systems that offer quick seeding windows. If a cover crop is being planted for erosion control and won’t be harvested, the grower then assumes the risk if that cover crop doesn’t appear on the herbicide label. However, if that cover crop will be harvested as forage, either mechanically or by livestock, then rotational restrictions on the label must be followed. For more information on herbicide rotational restrictions, refer to FAQ #5 in the Soil First® Management Guide.

5. USE MIXES.
Cover crop mixes allow for diversity and opportunity to spread out risk. Mixes also allow for reduced weather risks, help break pest cycles and prevent erosion that some monoculture species are vulnerable to. Added benefits include nitrogen fixing and improved soil health as well.

Measuring Sorghum Quality Vs. Corn

Measuring Sorghum Quality Vs. Corn 
The challenges of Spring 2017 have many producers looking outside the box to produce quality silage for livestock. While many forage options exist, most require a drill to plant and multiple passes over the field for optimum harvest.

One exception to this is forage sorghum. A corn planter or drill can be used to plant this seed and when using the proper maturity, the producer can expect to harvest in a relatively short period. There has been much improvement with forage sorghums the past two decades, including improved standability with a leafier plant, improved digestibility with the BMR6 gene and improved tonnage, often outperforming corn.

95 BMR forage sorghum is the ideal choice for a dairy or feedlot producer looking for a product that can deliver superior silage quality using a one-cut system. Some benefits include:

  • BMR 6 gene: low lignin technology for improved digestibility and feeding efficiency
  • Wide adaptation: can be used in many soil types and production environments
  • Earlier maturity & disease resistance combination allow this hybrid to be used across the U.S. (North to South)

In Southern US: this hybrid works great as a ratooning crop (crop goes to full harvest and is allowed to regrow for additional harvest)

One question we’ve been asked is how does forage sorghum compare to the quality of corn silage?

When managed properly, the 95 BMR not only provides the necessary tonnage, but also provides quality feed that rivals quality corn silage. Many producers rely on the high digestible fiber of the 95 BMR BD to maintain or even improve meat or milk production of their herd. Due to high digestibility, it is recommended to increase cut length to ¾” to 1 ¼” to slow down the passage through the rumen.

Fertilizing Pastures – Holiday Schedule

Good soil fertility is extremely important for productive pastures. Even the best, most improved forage species and varieties need adequate amounts of nitrogen, phosphorus and potassium, as well as secondary nutrients, to perform their best. We always recommend testing soils first to determine how much fertilizer one may need.

If soil test results show that fertilizer is needed, a good program to follow is to divide your recommended fertilizer amount (based also on your annual production goals) over our three summer holidays: Memorial Day, 4th of July and Labor Day. Here’s a brief snapshot of what those three applications offer:

  • Memorial Day – happening after spring flush slows initial growth and boosts stand productivity into summer
  • 4th of July – jump starts pastures for fall and winter stockpiling
  • Labor Day – extends the grazing season; allows energy reserves to be restored for winter and the following spring

If three applications do not make sense, because of time and/or budget, then transitioning to two treatments still works – Memorial Day & Labor Day.

Nutrient applications should be made based on production goals.

Take Note – Timing of Fertilizer Application is Important: 

  • Since many cool-season grasses grow vigorously in spring on their own, applying additional N can hurt overall competitiveness and thus impede growth of other components, notably legumes
  • Avoid applying N during extreme dry conditions, as leaf burn can occur

It doesn’t make sense to time fertilizer applications when large weather events are forecasted – fertilizer is lost to streams and waterways instead of getting to the target

Preventing Grass Tetany in Spring

Preventing Grass Tetany in Spring
As we look forward to warmer temperatures, cool-season pastures become lush green and grow quickly. This growth can result in challenging conditions for grazing cattle, primarily lactating cattle. Grass tetany (or grass staggers) is a metabolic disorder caused by cattle foraging on high moisture, low nutrient (magnesium (Mg)) grasses. Animals with this disorder find it difficult to eat enough dry matter to meet their nutrient requirements. It generally affects older lactating cows but can also be an issue in dry or young cows and in rare cases, growing calves.Symptoms of Grass Tetany Include:

  • Nervousness
  • Staggering
  • Spasms
  • Convulsions
  • Overall lack of coordination

Further, this condition can lead to decreases in milk production and death. If grass tetany is suspected, a vet should be contacted quickly as treatment can save affected animals.

Timing & Species:
Grass tetany usually occurs when pastures are green and lush in spring, but can also occur in fall or winter, when cool-season grasses or small grains begin to grow quickly. Usual suspects are orchardgrass, perennial ryegrass, timothy, tall fescue, bromegrass, Kentucky bluegrass, annual ryegrass, wheatgrass and small grains (wheat, oats, barley, triticale and rye). Another possible occurrence is cattle wintering on corn stover (or anything with low Mg levels). Elevated N and K levels usually increase risk of grass tetany by decreasing levels of Mg available.

Management Tips to Help Prevent Grass Tetany:

  • Add legumes. Increasing legume content of pastures with clover (or alfalfa) can offset low Mg due to higher Mg levels in these species.
  • Refrain from placing cattle in recently fertilized fields or where significant amounts of manure have been applied (higher N & K levels tie up Mg)
  • Test soil and forage. If low Mg levels are suspected, testing soil and/or forage can provide insight into possible problems.
  • Use high Mg supplement. Animals should be fed a high Mg supplement or free-choice mineral (containing 8-12% Mg). Mg may be added to a protein or liquid supplement, grain mix or silage.
  • Handle affected animals gently. Treatment of cows in early stages of grass tetany can be effective, but animals should be handled gently to produce the least amount of stress possible. Corralling or roping can cause stress that may lead to death.

Summer Select™ Hybrid Pearl Millet Addresses Summer Annual Challenges

LA CROSSE, WI (May 18, 2017) – A new pest continues to spread its way to fields in many areas of the U.S. The sugarcane aphid, which attacks forage sorghum, grain sorghum and sorghum-sudangrass, causes yield loss, uneven or lack of head emergence, poor grain set, increased lodging and more.

Feeding sugarcane aphids remove nutrients used for plant health and grain yield. This, along with secondary diseases, causes sorghum leaves to die. Without proper hybrid selection and scouting practices, this pest can cause up to 100 percent yield loss. In addition, it leaves behind a shiny, sticky honeydew that creates a mess on hands and equipment.

Summer annual breeders are working to develop plants with resistance to this insect. While some grain hybrids now have sugarcane aphid tolerance, limited options exist for sorghum-type forage.

To address this, La Crosse Seed has partnered with top breeders to acquire what it believes to be the best products for forage and grain producers to combat sugarcane aphids and other challenges.

One such product is the Summer Select™ Hercules BMR BD Pearl Millet. Released in 2016, the response to this multi-cut summer annual “has been very positive,” per Chris McCracken, director of business development at La Crosse Seed.

After numerous trials and side-by-side comparisons with sorghum-sudangrass, Hercules BMR BD has not only demonstrated similar yields, but has also displayed sugarcane aphid resistance plus higher digestibility and energy.

For producers looking to maximize productivity while also reducing cost, this improved summer annual has a lower seed cost than sorghum-sudangrass. “Today, Hercules represents average seed cost savings of $12 per acre,” said McCracken. “It is a fantastic alternative for producers in need of economical, efficient forage.”

Additional advantages to the hybrid pearl millet include:

  • Faster emergence and regrowth.
  • Brachytic dwarf structure for improved standability and management.
  • Dry stalk technology for improved drying time.
  • Flexibility to handle a larger range of soil types than sorghum-sudangrass.
  • No prussic acid concerns.

The company also recently released four new grain sorghum hybrids under its Summer Select summer annual portfolio; two of which exhibit natural tolerance to sugarcane aphid.

Renovating High Traffic Areas in Pastures

Renovating High Traffic Areas in Pastures
From late fall to early spring, pastures can be beat up. High traffic areas (feeding areas, sacrifice lots, alleyways, watering areas) are often bare and muddy from early spring to early summer. To slow/reduce soil erosion, compaction, forage damage and weed problems, these areas should be renovated, but proper management is critical and often the difference between success and a muddy mess. Overall, animal health increases when muddy areas are reduced as well.

Recommended Options & Considerations
Annual (Italian) and perennial ryegrass are good options when renovating these areas – annual ryegrass as a short-term fix and perennial ryegrass as a residual or long-term solution. Each can increase overall quality of the pasture or hay field being renovated:

Italian ryegrass is best suited for spring plantings. They provide excellent forage potential with the added flexibility of not going to head in the seeding year.

Perennial ryegrass, like most cool-season grasses, may have a “summer slump” July – September (depending on region/climate). But with proper fertilization and grazing rotations, it can last several years. Use tetraploid ryegrass, which tends to be more upright with wide leaves and higher quality. A key advantage of ryegrass is palatability.

We also carry and recommend SucraSeed high sugar ryegrasses, with the attributes of ryegrass (quick germination, easy to establish) plus tolerance to summer heat and dry weather thanks to a higher level of carbohydrates and stored energy.

I’m Ready to Renovate my Pasture

 

Ryegrasses can be used for pasture, dry hay or silage, and establish quickly, so they work well when seeding windows are small and ground cover is critical. When harvested in the vegetative state, ryegrass is very high in digestibility (often referred to as “Queen of the Cool Season Grasses”). Because of higher nutritional values (namely protein), it can be used in dairy systems too.

Additional tips to ensure success:

  • Fertilizer and lime should be applied per soil test results. Split applications of N (40-50 lbs. actual/acre) can be especially beneficial.
  • Do not over-apply N when interseeding into existing grasses. Added N can lead to increased competition from established components in the field already.
  • Keep livestock and/or heavy traffic off newly seeded areas to allow for seedling establishment
  • Do not overgraze and allow for a rest and regrowth period before grazing again

MANAGING SPRING OATS ALONGSIDE ALFALFA – ARE THERE OTHER OPTIONS?

MANAGING SPRING OATS ALONGSIDE ALFALFA – ARE THERE OTHER OPTIONS?

For many years, the common thing to do when spring seeding alfalfa was to add oats as a cover or companion crop. Back in the day, oats provided straw and grain for livestock (and horses) used around the farm. Today, a different kind of horsepower is used – and the thought of integrating oats as a spring cover crop may need to be re-thought, or at least revisited.

Using oats as a cover crop is common in fall plantings between traditional cash crop rotations like corn and soybeans. Oats planted alongside other grasses and broad-leaves can provide numerous benefits from erosion protection to weed control. This is one popular and agronomic use for oats. However, we are frequently asked for recommendations on a seeding rate for oats when planted with alfalfa in spring. Let’s take a look at what we’ve learned:

Seeding oats for spring grain is one thing – usually achieved with seeding rates somewhere north of 2 bu/acre, even up to 3 bu. When oats are used for silage, we typically like to see a seeding rate a little less – more like 1.5 – 2 bu/acre. Some of our recommended oat varieties are included here.
When seeding oats alongside alfalfa, considerable damage can occur to the alfalfa stand, especially if the oats are allowed to produce grain. Allowing oats to mature further decreases the forage quality:
Average Forage Quality Values for Oats Harvested at Different Maturity Stages:

Seeding rates approaching 1 bu/acre can be too heavy and cause irrecoverable stand losses. We actually like to see a seeding rate around .5 to .75 bu/acre if it’s actually necessary to add a spring cover crop. – Undersander, 2007
 
So, we must make a decision to either plant alfalfa for future forage yields, OR include oats for a short term gain from the oat grain, silage or straw. From a financial perspective, we think it’s easy to figure out which forage yield is and will be more valuable.If small grain yield is necessary, consider spring barley, which is typically ready across the Midwest at least a couple weeks sooner than oats – allowing the alfalfa crop growing underneath more time to recover.

Other cereal grains, like triticale, can also be used. However, spring triticale can be hard on the alfalfa stand too – it matures similar to oats and can be more difficult to manage for silage.

Granted, spring oats are an ideal ground cover on highly erodible (HEL) soils and planting alongside alfalfa can reduce soil, nutrient and seed loss from erosion in those environments. If plans include use of Roundup Ready alfalfa, it’s then possible to terminate when oats reach 6-12″ high (remember, dead or dying oats provide excellent erosion protection as well). This typically occurs around 30 days after emergence.

Or, even if the goal includes harvesting oatlage later in spring, glyphosate could be used as a “clean up” post harvest (about 2 weeks after harvest). This application could also include an insecticide application if warranted. La Crosse Seed offers a Roundup Ready alfalfa option: FF 4319.A2 RR Alfalfa.

Ultimately, plant alfalfa in the spring because the goal is a solid stand aimed at producing forage for the foreseeable future. Recognize that it may make sense to concentrate spring grain forage goals on other acres, where one could also integrate crops like forage peas to increase overall palatability, while increasing protein and lowering fiber content. La Crosse Seed specializes in spring grain mixes with peas, and has decades of experience managing spring pea and grains. For information on our pea mixes, click here.
