What to Do With Rutted, Compacted Fields

It's time to think about what type of tillage, if any, is going to be performed in this spring.  Fields with ruts left by harvesting equipment last fall may require additional consideration.  If the ruts lead to deep compaction, then ripping the soil is an optional if we have a dry spring.  Ripping wet soils accomplishes very little and can make the situation worse.  Since we are have a mild winter so far and the ground is not frozen, it's a good time to walk fields and measure compaction.  This can be done with a soil probe, tile probe, or a compaction meter (penetrometer).  Pereferably, this is done a couple days after the soil has reached field capacity from a rainfall event.  Be sure to check turn rows, heavy use areas, and where different soil types exist in the field.  Below is a good article on spring tillage management in fields with ruts and compaction. 

Many corn and soybean growers have harvested record crops. However, they may be facing compaction issues because of saturated soils at harvest. Combines and grain carts caused deep ruts and severe compaction issues.

So what can farmers do to break up that soil and smooth out rough fields?

Farmers may be facing two types of compacted fields. One type is where there is an isolated compacted area, such as end rows or poorly drained sections of a field. It is suggested to do whatever is necessary to get that area ready for planting and leave the rest of the field alone.

The other type is compaction across the entire field, and whatever is done in terms of tillage operations is applied to 100% of the field.

The following options will aid growers in preparing for spring planting:

• Do nothing about deep compaction, especially if it turns out to be a wet spring. You don't want to make a bad situation worse by performing deep tillage on wet soils because it destroys the soil structure. If a farmer can get a no-till planter or drill across rutted ground reasonably well, it may be better to take a slight yield hit in 2012 and then try to correct the deep compaction problem (if it exists) after harvest.

• Perform light shallow tillage, but only if the soil is dry. If ruts or tracks are more than 2 or 3 inches deep, a light tillage pass can smooth out the soil and create a surface satisfactory for planting. Fill in ruts enough to eliminate standing water.

• Use 2011 as a valuable lesson. Extra tillage in the dry fall of 2010 led to compaction and traffickability problems in 2011. Consider the benefits of continuous no-till, especially with controlled traffic. Strip-till, either fall or spring, may be best for corn planting


Research has shown that compaction affects crop yields. Years of OSU Extension research on Hoytville silty clay loam showed that through compaction, 10% to 15% of the potential crop yield was being left in the field.

To counteract yield losses from compaction, researchers recommend no-till production. Recent research shows that continuous no-till soil resists compaction from heavy loads better than soil that is subsoiled every 3 years, resulting in higher yields. Firm no-till soil resists compaction better than deep-tilled soil. The first trip across loose soil causes about 85% of the total compaction.

Delaware Agronomic Crop Budgets

The Delaware agronomic crop budgets have been recently updated by UD Cooperative Extension.  The budgets can be found by visiting the agronomic crop budgets homepage at http://ag.udel.edu/extension/agnr/CropBudgets/  Crops include conventional dryland corn, no-till dryland corn, conventional irrigated corn, conventional no-till corn, sorghum, dryland full season soybeans, irrigated full season soybeans, no-till full season soybeans, barley/double crop soybeans, and wheat/double crop soybeans.  The budgets includes estimated costs for items including fertilizer, chemical, field operations, etc...   The estimated costs are only for reference and you should use your own costs in the spreadsheet for accuracy.  There is also a section to put the best, expected, and worst crop price and yield.  While you will not be able to modify the spreadsheet if you open from the website, save a copy to your own computer if you wish to modify.  You can also add other line items in if necessary.  By completing crop budgets, it gives you an plan ahead of time of what crops will be most profitable.  Inputs and commodity prices are always changing so having a spreadsheet budget on your computer will be beneficial.

Soybean Contest Results-PA

Penn State Extension and the Pennsylvania Soybean Board have recently released the results of the 2011 Pennsylvania Soybean Contest.  Several entries in the contest are over 80 bushels per acre.  Results also include comparisons of management practices.  It is interesting to see some of the populations, planting dates, and planting practices used by entrants.


The results of the 2011 Pennsylvania Soybean Contest have been posted http://cornandsoybeans.psu.edu/soybean/yieldindex.cfm. Entries were down a bit this year due to the unusual weather, but we were still able to document some top yield production in the state. The top yield this year was 86.28 bushels per acre, recorded by the Charles Farms, Inc. from Lancaster County. They were one of four entrants that produced more than 80 bushels per acre this year. This year the contest also recognized top yields from farms in the West Tier and Central Tier regions of the state. The top yield in the West Tier was recorded by Rick Telez from Lawrence County with a yield of 76.39 bushels per acre while in the Central Tier, David McLaughlin topped the contest with a yield of 65.68 bushels per acre.
These top yields reflect the top management of our producers and the genetics available to them. Management practices used by the soybean contest entrants tend to reflect some of the results from agronomic research studies in that top yields can be produced with a range of seeding rates and row spacings and that soybeans are tolerant of delayed planting through the end of May. Soybeans are also an ideal no-till crop and this is reflected by the 83% of the entries that were no-till. Our producers in the contest are also following some of the national trends, moving to more planters (78%) compared to drills (22%). Many producers are opting for the planters with split rows as 56% of the entrants were using rows from 11 to 20 inches. Only 33% of the entrants applied a fungicide, which likely reflects the lower disease pressure this year and the conscious effort many producers make at using and integrated pest management approaches on their soybeans.

Herbicide Update

The Ignite herbicide brand will have its name changed back to Liberty in 2012.  Below is the press release from Bayer CropScience:

Bayer CropScience announced that the global brand Liberty® herbicide will replace the Ignite® herbicide brand for use on LibertyLink® crops in the U.S. market starting in the 2012 crop season.
“Globally, the use of the LibertyLink system is experiencing rapid adoption due to growing weed resistance to glyphosate and the excellent germplasm performance, which in turn is increasing the demand for a non-selective herbicide,” said Al Luke, head of broad acre crop marketing for Bayer CropScience. “Bayer is investing to increase the global production of Liberty herbicide and help ensure adequate supplies, especially in the rapidly expanding U.S. market.”
“Liberty herbicide still offers the same benefits and levels of performance as the former Ignite herbicide, including the new 65 ounce seasonal maximum for soybeans,” Luke said. “And Liberty herbicide should be applied according to label directions.

Annie's Project 2012

Annie's Project will begin on January 25, 2012.  The event is going to be held in Sussex County at the UD Research and Education Center in Georgetown, De. There is a fee and registration is required to attend the workshops.  For more information, contact Tracy Wootten at (302)-856-7303.

Annie was a woman who grew up in a small town in Northern Illinois. Her goal was to marry
a farmer and she did. Annie spent her lifetime learning how to be an involved business partner
with her farm husband. Together they did great things, but it wasn’t easy. This is Annie’s
Project – to take her experiences and share it with farm women living and working in a complex
business.

Objectives
Annie’s project is designed to empower farmwomen to manage information systems used in
critical decision making processes and to build local networks throughout the state. The target
audience is farmwomen with a passion for business and involvement in the farm operation.

Project Topics cover the five areas of Risk Management – Production, Market, Financial, Legal
Risk, Human Resources.

Evaluating Disease Resistance in Soybeans

VIPS (Varietal Information Program for Soybeans) is another resource that growers can use when selecting soybean varieties for next year.  While the program is housed in Illinois, it tests many of the same commercial varieties that are grown here in Delaware.  It also captures some useful information on  disease resistance including SDS (sudden death syndrome) and green stem.  The southern part of Illinois (Belleville, Elkville) would be the most comparable to our growing climate.  Click on the picture below to go to the website:

Freeze Injury to Wheat

While the recent drop in temperature will not affect the wheat crop, freeze injury can be a problem on winter wheat.  Spring is the time of the year to be concerned with low temperatures.  During the winter, wheat has a strong tolerance to cold temperatures (see graph below).  As temperatures warm in the spring and the plant switches over to reproductive growth, it becomes susceptible to cold temperatures.  The risk for freeze injury increases when temperatures increase rapidly in late winter, early spring, causing the plant to develop at a rapid pace.  With the plant developing quicker than normal, a late spring freeze could cause injury.  This is highly dependent on the growth stage of the wheat.  To check for freeze injury, split the wheat plant's stem to view the growing point.  This can be extremely small, but should be present in the spring (after vernalization).  It is located right above the uppermost node, and will appear as a very small version of a wheat head.  Normal color is bright white to yellow-green and is turgid.  A damaged growing point is off white or brown and water soaked in appearance.

How Phosphorus is Lost from Farmland

A good article on how phosphorus moves in the soil and how it is lost:

While phosphorus (P) is an essential nutrient for plant growth, P runoff from the landscape can also lead to degradation of surface waters. Enrichment of streams, lakes, and rivers with P leads to algal growth and subsequent decay, which depletes the water of oxygen necessary for fish and other aquatic organisms. Not only does this process (known as ‘eutrophication’) result in degraded aquatic habitats, it makes surface waters unfit for recreation or as a drinking water source.

Common sources of runoff P are eroded soil and surface applied manure or fertilizer, but it can also originate from fields without these obvious P sources. Soils having high P levels also produce runoff that contains high concentrations of P. These high-P soils are typically the result of field or farm level nutrient imbalances; these imbalances often extend to the regional scale. Phosphorus that is mined in Florida and used as fertilizer in the Midwest is commonly shipped to Eastern farms in the form of livestock feed. Only a fraction of the P in the livestock feed leaves the farm in the form of food, fuel, fiber, or live animals. The majority of the P is distributed on the land in the form of manure, often at rates selected to meet the nitrogen need of the crop but exceeding the P need of the crop. Phosphorus accumulates in the soil until the soil cannot absorb anymore; runoff P concentrations tend to increase as this accumulation occurs.

P Loss Pathways

Phosphorus has two forms in runoff, soluble and particulate. Soluble P comes from the release of P from soil and plant material and is completely dissolved in runoff, while particulate P is attached to eroding sediment or associated with organic material. Erosion always occurs on the soil surface, but the other P-loss pathways can take place both on the surface and through the subsurface.

Surface:

Tilled fields and overgrazed pastures are especially susceptible to the P loss that is associated with erosion. Phosphorus binds very strongly to soil particles, and the erosion of these soil particles can be a significant source of P loss even if the soil P level is low. Particulate P is the dominant form of P in runoff from cultivated lands.

Dissolved P can also be carried in surface runoff from tilled or untilled fields. Although different soils can adsorb different amounts of P, for a given soil the higher the soil P level is in the field, the higher the P concentration is in the runoff. The soil P level is more uniform in tilled soils because of mixing, but is highest in the uppermost soil layer of pastures and hayland. As runoff flows through a field and interacts with surface soils, P is released in a dissolved form. This release results in the dominant P loss pathway from grassland.

Highly-soluble P in manure and fertilizer, and the manure and fertilizer itself, can be readily washed off of the soil surface by runoff from rainfall or snowmelt. Application rate and timing are important factors in how much P is lost through this pathway. A couple runoff events following nutrient applications can represent the bulk of the surface runoff P for the entire year.

Subsurface:

Dissolved P can move from upper soil layers into shallow groundwater with percolating water. This is more common in sandy and gravelly soils, but can be enhanced by large pores (e.g. wormholes) in other soils. Once P is in shallow groundwater beneath a field, it can flow to a bordering stream or ditch. Drainage tile can increase the magnitude of this P loss pathway.

A little-recognized P loss pathway is the movement of manure or fertilizer P from the surface directly into drainage tiles through large soil pores or cracks. This process has been observed and demonstrated in many agricultural soils, but is more likely to occur when applying liquid manure sources.

Management to Limit P Loss

The risk of P-loss from a field can be divided into two categories: 1) source factors and 2) transport factors (Table 1). Source factors are directly related to the amount of P that water interacts with as it passes through a field, and can often be controlled with management efforts. Transport factors are related to the volume of water leaving a field and the likelihood of that water reaching a stream. Various management and conservation practices are also helpful for controlling transport factors.

Phosphorus source control is achieved primarily by managing the rate, timing, and method of P applications to fields. Additionally, the type of P amendment (e.g., inorganic fertilizer vs. poultry litter) should also be considered to account for varying proportions of water-soluble P that can be readily lost to runoff.

The rate of P additions to a field should be based on the agronomic need of the crop being fertilized. When P is applied at rates greater than the agronomic need of the crop, P will accumulate in the soil. As P accumulates in the soil the risk of P loss increases. Annual soil testing allows for informed and economical use of P to meet crop needs.
The timing of P application can have a large influence on the amount of P in runoff. Phosphorus sources should not be applied to frozen or saturated soils. Probability of runoff in many areas of the Mid-Atlantic is greatest in the winter with snowmelt and in the spring with rain on saturated soils. Large rain events in the summer can also produce significant runoff. Weather predictions can be used to select application times when the forecast is for relatively dry weather.

The method of P application can be on the surface, on the surface followed by incorporation, or injected into the subsurface. Injecting or incorporating P sources can reduce P loss if it can be done without increasing the risk of erosion. Injection and incorporation also forces P into deeper soils and reduces P-enrichment of surface soils that interact with runoff.

Phosphorus transport control relies on a number of management and conservation practices that serve to reduce the risk of runoff P from reaching a water body. Even with proper P transport control measures, some fields and soils inherently have a greater risk of P loss. In these fields, source control measures become more important.

Soils that are more likely to produce large amounts of runoff have an increased risk of P loss. Several management practices can be implemented in these fields to help reduce runoff volumes. Cover crops, reduced or no-till, and contour farming all help precipitation to infiltrate and reduce runoff.

Concentrated flow paths (ditches, natural swales, etc.) increase the risk of P loss by greatly reducing the opportunity for runoff to infiltrate into down-slope soils and for sediment-bound P to settle out or be trapped by vegetation. If concentrated flow paths do exist in a field and cannot be avoided, making sure they are well vegetated and are not eroding will help to reduce P loss.

As the distance from a field to a stream becomes shorter, the risk of P loss increases. This risk can be reduced by leaving forest or grass buffers between the field and the stream. These buffers trap sediment-bound P in runoff and help prevent stream bank erosion, another potential source of P loss. In general, the wider the buffer, the more effective it is at trapping P.

Erosion control methods are also very effective at reducing P transport. Avoiding overgrazing, maintaining vegetative cover, and reduced or no-till practices limit the amount of sediment-bound P that can be moved with runoff.

Phosphorus transport through the subsurface is difficult to control. Excessively drained soils increase the risk of transporting P through the subsurface; drainage tile can also enhance this risk in less well-drained soils. If possible, construct wetlands at tile outlets to slow runoff and help reduce P loss through adsorption, sedimentation, and plant uptake.

Distance to stream
Buffers allow for infiltration or filtering of runoff
Erosion
Erosion is a significant source of P loss from tilled fields and damaged pastures
Subsurface flow
Subsurface drainage, preferential flow, and highly permeable soils can enable leaching of P


P-Index

The P Index is a tool that was introduced in the 1990s, and is now a widely used method for evaluating the risk of P loss from agricultural fields. The P Index rates the source and transport factors of a particular field, with the understanding that the risk of P loss is highest when there are interactions between P sources and transport pathways. Conservation practices and management are considered when evaluating risk of P loss. Each state has developed their own version of the P Index based on their local soils, climate, and landscape. Most versions are straight-forward, and are designed to help nutrient management planners and producers evaluate the effects of alternative management practices on P loss.
