First Major Frost

This morning the thermometer dropped to 28 at my house just before sunrise. This will be the first attempt at a hard frost (below 28 degrees for a few hours) but not successful at least at my house. It does appear we may have a general warming trend over the next few days as high pressure builds in and the trough in the jet stream moves over us. Overall I think we will see some damage on sensitive plants in areas but at this point it appears we have another week of growing season left.

First Signs of Frost

This morning as the dawn began a light frost settled on the grass and my vehicle. Another reminder we are progessing further into fall. The long range shows temperatures in the middle 30's for lows over the next few days. This is far from the hard frost it will take to see damage but reminds us the growing season is drawing to a close. Keep an eye on susceptible crops such as late planted corn. Likely we will begin to see some burn on leaf margins over the next week in some fields, however little actual damage should be done to the crop.

It's Bean Time!

With combines busy around the county corn, and now beans, are getting to their harvest windows. The field I was in yesterday was averaging around 72-75 bu/ac. Hopefully you will find some high yields in your fields as well. As always make certain your combine is properly set and get out to check what is coming out the back end of the machine. Harvest losses can be very high with poorly set machines. Also if you are no-tilling remember to adjust your choppers so that you have uniform distribution across the header width. This adjustment will pay large dividends next time you plant the field. Regardless of the crop make sure your combine isn't putting a large amount of commodity out the back end. Hopefully you can enjoy a safe and happy harvest with lots of high yields.

Cut Costs, don’t eliminate!

As I was working on my father-in-law's dairy farm this weekend I couldn't help but think of the current economic situation facing all dairy farmers and most of agriculture in general. Things are tight and because of this costs need to be reassessed. As I was bedding up some cows I thought of how crucial some costs really are. Take the straw I was using at that point. I could have just eliminated the use of the straw to cut costs, however we all know the long term affects of that would be devastating in cattle health and production. This got me thinking about all the upcoming costs on the agronomic side of farming and where we may try to eliminate costs that may hurt us in the long run. Here are some of my thoughts.

Soil testing is a practice we preach all the time, and the fall is the best time to do it. Although this can be a low cost practice it may be one that gets a scrutinizing eye as we hit hard times. Depending on your current testing practices you may have some room to cut costs here, but they should not be eliminated. If you soil test every year you can probably take a year off. Use last year's soil tests along with this year's crop grown and yield to estimate nutrient removal and thus see what nutrients need to be added for next year's crop. If you haven't soil tested in over three year you ought to consider taking soil samples to check where you are at.

Once you have soil tested the question always is where do I spend money first? The most important area in soil health and nutrient availability to the plant is pH. If you have low pH (low depends on crop but typically no lower than 6.0) lime is the best product you can buy. Dollar for dollar this will return the greatest on your investment. Soil pH is a driver in many other nutrient cycles as well as the microbial population in the soil. If you have only one product you can buy for your soils make it lime. This year we have seen many cases around the state of poorly inoculated soybeans, one of the contributing factors to this has been low pH.

Fertility in the form of commercial fertilizers is always a large expense on most farms. Many farms in this area do have the availability of manure, however many of us need to supplement our manure nutrients with fertilizer. One of my biggest concerns at this point in time is potassium. Due to last year's high prices for potassium many decided to take a year off of buying potassium and mine some of the potassium in the soils. This year due to excellent rainfalls many of us have experienced yields at the high end of our expectations; this means more potassium has been used. Now we are in a situation where very few may want to invest again in potassium even thought the price is falling. This could set us up for some deficiencies. If I were to offer one suggestion on potassium fertilizer at this point it would be this. If you have manure at your disposal get it tested for nutrients. If commercial potassium is more expensive then nitrogen, apply your manure at a rate to supply potassium and supplement with nitrogen. If you are going into corn the use of a mid season nitrogen test such as the PSNT or Chlorophyll meter along with sidedressing can save money as will. In addition to potassium make sure you keep an eye on boron levels on alfalfa. This year we have had great yields so therefore if you are harvesting silage of any type, hay, and/or fodder you have a lot of nutrients in your bunkers, silos, and barns.

As we try to manage this current time of tight economics we need to take a good assessment of cutting costs without hurting ourselves in the future. With good soil tests you may be able to find some areas where you can cut costs, however we want to maintain enough nutrition in the soil to allow for good yields in the years to come. Many times if we get behind in nutrition in the soil it will take a long time to get it back. Additionally, if we don't have soil tests we will need to wait until we see deficiency in the crop before we know we are behind. At that time we have lost yield and that can be a costly mistake.

Adjust those kernel processors!

As the corn slowly dries down I'm seeing some drier ears on some very green stalks. If we continue this trend it may lead to some issues in getting available energy in our silage. If you have a kernel processor you are steps ahead in this area already. However, just because you put out the cash doesn't mean it will work without some attention. When you are out harvesting make sure to take some samples early on to see how the processor is working. To check the kernels take a handful or two of silage and place it in a 5 gallon bucket. Fill the bucket with water then slowly pour off the water. Once the water is pretty well gone you should be left with only kernels. Carefully inspect the kernels to make sure they are well processed and cracked. If the kernels are not cracked adjust the processor to a narrower spacing and test again.

Corn Starts to Dry Again!

I just got done looking at moisture on our plot. In review this was planted on the 29th of April and the variety I'm looking at is a 114 day variety. The moisture this morning finally has moved from the 30-31% D.M. we have been holding at for about a week. Today we are standing at 31.7% D.M. Although this isn't a huge jump it is finally in the right direction. The downside to this is that we are to have rain today and tomorrow which means we probably won't be drying down much going forward. So with all this said it looks like we may be into September before we really get silage harvest rolling. I know many have been pulling into the fields this week but I think for the most part in the county we are still waiting. The silver lining to all of this is that we have quite the crop sitting in the field when we do start in.

Cover Crop Plot Planted in Franklin County

Today we planted the cover crop plot in Franklin County. This year we have 19 species and mixtures in the plot. It will be interesting to see how each performs. The plants include grasses, legumes and some non leguminous forbs. I will be keeping you up to date on the growth as well as winter hardiness of each species. I will also hold two field days at the plot, one this fall and one in the spring. Until then you can feel free to stop by the plot and see what is happening. It is located on Walker Rd. just east of Chambersburg. I want to say a special thanks to Ron Hoover of Penn State for helping establish the plot and Stanley Burkholder for the use of the land.

Soybean Aphids Continue to Dwindle

After scouting the Chambersburg plot again today for soybean aphids it appears that the population continues to decrease. As I stated before we never came close to the threshold, however now that hot weather has hit we are starting to see the populations react with a decrease in populations. The beans I'm scouting are in R6 so even if we hit a threshold population now (250 aphids per plant) it would not be economical to spray. If you do have late planted or double cropped beans make sure you still pay attention to the aphids. Hopefully the populations are dwidling all around, however you still may have heavy presure in some areas of the county.

So here it begins

So I have now rocketed into the world of blogging. This blog will be mainly focusing on the area of crop and soil science (agronomy) in Franklin County Pennsylvania. With this being said I will warn you that comments on the dairy industry and livestock production will likely come into play as well. Hope you enjoy this and I'll do my best to keep it up to date with relevant information.
