Cover Crops

(The 14 plant mix of cover crops in front of the Pine Ridge Farm)

This fall, we did something a little different after harvesting our wheat acres, which was putting in a cover crop.  What is a cover crop?  It is a second crop put in towards the end of the growing season to provide ground cover, hold nutrients in the soil, increase organic matter, and reduce compaction.  All of these things should help our primary crop production in the coming years.

These all sound like really great things, so implementing a cover crop program seems like it would be easy, obvious, and immediately cost effective, but that isn't the case.  One obstacle is figuring out how to get the crop into the field, and to come up for a good cover before everything freezes up.  Wheat is harvested at the end of June, so we have plenty of time to haul manure and plant the crop before the ground freezes. It is a good place for us to start and see if it works before we start incorporating it into our other crop programs.  We are not quite done harvesting corn for this year, so to put a cover crop into the corn field we would have to fly it on  sometime in August/September.

Of course we also have to know what to plant.  There are limitless possibilities of what to put in a cover crop mix based on the desired outcomes, climate, etc.  This year we are trying two mixes.  The first is a mix of 14 different varieties, some each of legumes, grasses, brassicas (root vegetables), and broadleaves.  Of course the stars of the show at least visually are the sunflowers, which are covered in bees and butterflies.  The other mix is 2 varieties- oats and tillage radishes- less expensive and less showy, but should get the job done.

All of these plants are supposed to winter kill (die off with the frost) but the grasses and roots will hold the nutrients in and keep the ground covered until they fully break down in the spring.  This should give us better nutrient availability from the manure we put on before planting, and better soil to plant into that will hold more moisture through the summer.  If everything goes as it is supposed to, we won't even have to till into the fields in the spring before planting, although right now that seems hard to believe with how tall and hardy our cover crop looks to be.

When we tried a cover crop in the past, we had just planted tillage radishes and they were giant (3 feet long and 4-6 inches in diameter), stunk as they decomposed, and we couldn't see any measurable benefit from having them in the field.  That being said, we may have had a yield boost that was subtle, so we aren't quite sure.  This year we worked with some people experienced with cover crops to choose our mixes and planting dates more carefully.  We also planted in a few different fields that aren't our top performers to see if we can make any improvements.  We won't know until next fall how the crops fair, but right now everyone is excited about the potential for improvement and learning new farming practices.

Farm Update: Yearly Training

(New landscaping around the finally finished office!)

It's been a busy month so far, with not much time for me to sit down.  Over the past two weeks, I have been putting together our chore schedule.  The chore schedule is a chart that lists every person working on the farm by the location they work at each month.  I make the schedule 6 months at a time, with each person rotating at least once to a different job than they normally do.  This keeps the work crews from getting grumpy by seeing too much of each other, and it means that every job has at least 2 people that can do it.   Most people like switching jobs, and everyone has some input as to where they work.  It's nice to have the schedule done for a few more months, since it involves so many people working together.

In the field, the crops are growing like mad.  The field crew is scouting the fields, and then deciding whether we need to apply any herbicides.  On our farm, we use hog manure as a good source of fertilizer, but some of our fields don't get any manure put on, so then we have to use another source of nitrogen, anhydrous ammonia, to get the crops the nitrogen they need.  The anhydrous is applied in June, so that is well underway.

The biggest project for me personally in June is the start of our annual animal care training.  I meet with every person that works with a pig from the farm, and train them on handling and care.  In all, I probably train 150-200 people, mostly in groups of 5 or less. This allows for a lot individual time, where I can answer questions and tailor each session to the specific group needs.  During this time, I will personally see every pig on the farm.

This training is a lot of work, but it makes sure that each person on the farm understands our standards.  It prepares each farm for audit, and makes sure that all of the records are being kept up to date. By doing these checks, I can make sure that nobody gets too far out of line, and that any questions get answered.  The training may only formally happen once a year, but on a weekly basis, we (being myself and the others on the farm) are looking at things we could do to improve our animal care.  We are having conversations about animal care everyday with somebody on the farm.  It may not be the easiest thing I do all year, but it is one of the most important.

6 takeaways from the Great Lakes Crop Summit

(Sign Welcoming Farmers to the Great Lakes Crop Summit in Mt. Pleasant, MI)

Last week I was lucky enough to attend the Great Lakes Crop Summit.  It is nice to have such a well run cropping event so close to home.  After listening to a dozen or so speakers over the two days of sessions, I gathered up a few key points.

1. Export markets are there, and they are important.  If grain marketing at most farms in anything like it is on my farm, we just work with our local elevator.  That isn't the worst thing to do, but being aware of the international trade climate, and of the other ways you market grain (at a premium), can really help crop farmers manage their risk.

2. We have to be business smart to farm smart.   Farmers are always proud of the fact that we farm out of love for the land.  We also tend to be slow to change or adapt.  By treating downturn years the same way as high profit years, we are really shooting ourselves in the foot.

3. Soybeans have a lot of unrealized potential.  In Michigan, soybeans are more of a rotational crop, not the main money maker.  The Great Lakes Crop Summit made me realize that we are giving up potential on soybeans just because we don't make them a priority.  Some of the things we can do with soybeans don't even take more time or money, it's just applying effort at the right time instead of whenever its convenient around corn.

4. New to cover crops? Get Help! After listening to multiple sessions on cover crops and vertical tillage, my biggest takeaway is don't go it alone.  Many things in crop farming are trial and error, but investing $25-45/ acre, or thousands in new equipment isn't something you should do without working with someone who has experience.  This will save a lot of trouble down the road.

5. Customer connection is key.  This is true in all parts of business, and not always something we think of first in agriculture.  Traceability is something that is gaining importance everyday with consumers.  Delivering a product tailored to our clients will result in better relationships, and a healthy pocketbook.

6. Manage your risk.  What happens when you have an accident on the farm?   How prepared are you to handle it?  This isn't just about insurance, but also about knowing what you should be doing before the accidents happen to protect yourself.  Working with your lawyer, your accountant, and your insurance agent to best guard yourself against potential harms will leave you feeling confident and prepared to handle any situation.

What's in a Crop Farmer's Toolbox?

I read a lot of articles about how farmers misuse GM technology, and how we are not really paying attention to how this affects the land, air and water. That as farmers, we are just using the cheapest, and easiest method, and not paying attention to other opportunities that are out there for better our crops and farmland.  Taking one step into the Farm Journal's Corn College last week, I quickly realized that people don't see the other farming practices we implement to raise a better crop.  GM technology is one of many tools in our toolbox, but what else is out there?

Let's start with hybrids.  These aren't necessarily GMOs, in that they are bred in the field to make certain traits.  There are those which are drought resistant, heat resistant, flood resistant, short growing season, long growing season, and everything in between.  As farmers, we don't just pick one variety to plant in all of our fields, we diversify our crop based on soil type, drainage, micro-nutrient levels, presence of irrigation, equipment, tillage style, and a host of other factors.  We try to balance our cropping portfolio so that no matter what the growing conditions, we can have a good crop.

Now we can talk tillage practices.  Farmers have a huge variety of field implements to use when tilling their fields.  Some farmers are strictly no-till, which is planting into ground that hasn't been cultivated in any way.  This is good for soil erosion because the ground is always covered with some type of cover.  Some farmers use plows or rippers to break hard pans in the soil and to inject manure for a natural fertilizer. Vertical tillage is somewhere in between, helping to create soil uniformity, thus better space for roots to grow.  We try to minimize our passes over the field by doing multiple things at once, making us more efficient on fuel, and less likely to cause compaction.

We use soil testing to figure out our nutrient levels to make sure that we put the right fertilizers in the right places.  We balance our soil and water pH levels to make the growing conditions suitable for the plants.  We use crop rotation and cover crops to improve the soil content, minimize weeds in the off seasons, and increase the organic matter.

Farm equipment now allows us to collect data and use GPS to practice precision farming.  We can map a field based on yield, and soil type to plant different varieties in places that respond differently within the same field.  We can manage our fertilizers that way too, so we are using less and growing more. Even the number of seeds we plant per acre is adjusted based on this mapping, giving each seed a better chance to thrive, and only planting as many seeds as the ground can adequately provide for throughout the growing season. 

Even more basic farming tools are being honed every time we go out in the field.  Did you know that the soil temperature at the time of planting greatly effects the ability for the seed to take up nutrients?  By monitoring our soil temperatures, we can give the plants the best start that we can, and utilize the fertilizer that is already in the ground.  In addition, we can adjust our planting equipment to make sure our planting depths are consistent, so one plant doesn't dominate another.

GMOs are part of the farmer's toolbox, but they don't make up for cutting corners in crop production.  Not every farm is using each tool, but each farm is trying to put together the best mix of tools to utilize the land at the highest potential.
