Retrofitting Equipment for Successful Direct Seeding

Bob Linnell, Conservation Agrologist

Success Factors:

There are a number of factors for success in direct seeding, and anyone either starting out or with several years of experience will concur with all of these as follows:

  1. Residue Management
  2. Weed Control
  3. Fertility Management
  4. Crop Rotations
  5. Seed-To-Soil Contact
  6. Management

Details of each of these are illustrated in slides shown today, but the basic content is very important especially when it comes to consideration of machinery modifications and retrofitting.

Residue Management

It is very important to spread the straw and the chaff over as much of the width of cut as possible. Evenness of spread is important as well as length of straw. Anchored standing stubble is also a consideration; usually not much taller than the spacing between the shanks on a hoe-press arrangement. A disc type machine can work in slightly taller stubble as long as the spread is even enough to prevent hairpinning of the straw under the cutting edge of the disc. Chaff should also be spread as wide as practical, because it is often the forgotten factor in field and crop management from a rotation trouble spot as well as a disease prevention and management point of view. Standing stubble of any kind in my part of the farming world usually means extra moisture; a good factor for extended rotations. Erosion events are not a reminder anymore that we have done something wrong.

Weed Control

This is very often a regional or soil related problem. Weeds are always there and must be considered every year because this factor can dictate not only what species you have, but also the growth pattern that it follows. Most direct seeders will usually follow a program of pre-seeding burn down of existing growth, and team up with an in-crop product as normal, and could include a pre-harvest treatment on some of their fields as well. After harvest or winter annual management is still a valuable practice, despite so-called "newer technology." It is always important to know what species of weeds you have on your farm, and in the area, and where they are sourced. Do they come from your neighbor, float downstream unto you, blow in on the wind, or come with hay or machinery? Take the time to find their source and you will be well paid for your time, because you will learn something.

Fertility Management

What options do you have in your area? Often fertilizer involves a lot of hauling, should you choose one type of product over another. A detailed review of your planned rotation will shed some light on just what type of plan you can put in place. If you select to use anhydrous ammonia, are you prepared to configure your equipment to assure seedling safety? If you select a liquid product, do you have the luxury of a surge storage tank available to you, to prevent stopping your seeding operation to go and acquire product without lengthy delays? Is a separate fertilizer application an option or a necessity for you? Seed-fertilizer separation is a very big and important question for most new direct seeders and deserves the necessary time to study it properly and not have a field blow up your profit potential.

Crop Rotations

Recommend a broadleaf-cereal rotation as follows: Cereal-Oilseed-Cereal-Pulse over four years. Check out the advantages for yourself.

Seed-To-Soil Contact

The magic word here is openers. Openers are a very big question and cause a lot of indecision for many producers whether they are beginners or more experienced direct seeders. A good guideline, is to look to your neighbors and take into account how you compare to them. It is important to know what your soil type is, what your rotation may be, what weed pressures you have, what your residue management plan is, and how flexible you cvan be, once you have finally decided on your best choice of opener type. A disc type opener pulls a lot easier than a hoe type, but it is limited in straw performance and fertilizer limits for seedling safety.

Management

Let's look at the systems approach to direct seeding. Most direct seeders follow a pretty set routine over the growing year. They start with a pre-seeding application of Roundup to control weed seedlings, followed about three days later with the one-pass seeding operation. They monitor the growth of the crops and spray at the appropriate time in-crop, watching for disease and insect potential. Their harvest is the same as the area surrounding them, with the possible exception of some pre-harvest application to control perennial weeds. Stubble is left as high as possible (according to the dictates of their seeding tool) to catch snow and allow their rotations to be extended to fit their four year pattern. Some continue to employ winter annual weed control measures. They use spare time to build more bins.

Row spacing, Power requirements, Speed

Remember, it takes 30% more power to pull a 40 foot-9inch space machine than a 40 foot,12-inch space machine. Most air drills require 5-7 hp/foot on a 12-inch space, depending on land slopes and tank size. Other things to consider are your methods of harvesting. If you must swath everything, then a paired row seed configuration is easier to swath onto than a single side band growth pattern. Wide (12-inch) spacing of rows means less cost per foot of machine to purchase, better residue clearance, but may reduce the ability of the crop to compete with weeds because of less canopy. If you are going to seed your entire farm with a one pass operation, you have more time, so you can make do with a smaller tractor and a narrower width machine. Speed of operation is a very important question that you should ask yourself on a regular basis. Four and a half mph is not too slow to direct seed; up to 5 or five and a half is possible, but there is usually a poorer seed bed left after a higher speed seeding job. For proper seed and fertilizer placement, it is advisable to keep your speed down.

What to Buy or Use?

Heavy soil, with larger percentages of clay, require different openers than loamy soils. An adaptable seeder frame is very often found right in your own yard, or district, perhaps not used for some period of time, but with a few modifications, is still perfectly functional. Local auction sales are often a good source of used machines that can be retrofitted to direct seed. Price is always an important factor. Conventional double disc drills give poor establishment results if straw or chaff is inadequately spread, because the downward pressure is insufficient to overcome hairpinning in heavy straw. Coulter assists in front of the discs may help, but often increase power requirements substantially.

Hoe type drills are good, if there is adequate under-frame clearance and row spacing combined with good rank spacing. Changing to narrow openers with side fertilizer banding capability is a cheap way to adapt these machines to direct seeding. Keep in mind that there are lessor amounts of fertilizer tolerated by plants when they are placed in a narrow band with very little separation between the seed and the fertilizer. An after market side banding opener is often the cheapest way to retrofit one of these machines, although a self designed opener is utilized by some farmers who are handy in the welding shop. Make sure you place the seed to one or both sides of the fertilizer row, and not on top of that row. Experience has shown that compromising seedbed quality for fertilizer placement is very undesirable. Seed always emerges and develops better if it is placed on firm ground at the right depth and packed from about.

On-row packing is pretty much mandatory in a direct seeding regime. You may "get by" for a year with coil type towing packers, but they are only about 20% efficient when you examine the actual seed in the row. Mounted packers on the back frame will work, keeping in mind that you only require some packing to be effective, and not huge amounts of pressure. Frame mounted packers will lift the back of the machine if you attempt to put large downward pressures on the packers, causing the rear rank of the machine to run shallow and result in poor or uneven emergence of the crop. A "floating" or flexible hitch is the best way to go in retro-fitting an existing cultivator frame to make it into a good seeding tool. This will mean a castor type arrangement needs to be fitted to the front frame to match the weight carried by the on-row packer sections at the rear of the frame. Shank mounted opener-packer units are also available, and will work in many soils.

Mid-row banding; this is a rapidly growing trend that reflects the need to place more fertilizer in a one-pass seeding operation, while maintaining seedling safety. The range of seeder openers available today does not always lend itself to adequate, safe application of large amounts of fertilizer or certain types of nutrient such as anhydrous ammonia. The development of mid-row technology has progressed very rapidly by many farmers and machinery manufacturers. Third tank technology has enabled many farmers to separate their nitrogen, starter phosphorous and seed into specific flow lines, or mix exacting amounts of phos with the seed and yet allow nitrogen to be placed mid-row to the shank opener. This mid-row concept is very safe for the seed and only adds a slight power requirement to the overall unit.

Tractor Factors: Does your tractor have sufficient hydraulic oil flow capability to allow fan drives and wing lifts to function? Would a gas or diesel engine drive on the airflow make more sense? Ground rive air-flow systems are a reality, but have some drawbacks in very wet seeding conditions of excess slippage on the part of the tractor.

Other "Didn't Think-of's:" Do you have a second truck to haul either seed or fertilizer? Is your sprayer capable of more use, often in somewhat rougher field conditions? Can you sell your discers, harrow-packer bar, extra field cultivator, before they become $40 per tonne, and utilize the money to modernize the tractor, or combine, or sprayer, or retrofit the drill to facilitate direct seeding?

Summary:

There are plenty of good field seeding units out there on the farms that, with a few after-market items added or changed, and an understanding of the systems approach to direct seeding, will render you capable of direct seeding along with the best of them. You know about these machines; you quite often already own them, or you may have seen someone else modify them to do a pretty good job of direct seeding with them.
