Planter Calibration Calculator for Seed Rate and Catch Tests

Seed rate calibrations ensures that you plant the proper amount of seed in your field. If you use too low of a seed rate, then the plants will be too far apart, which will reduce the yield of the crop. If you use too high of a rate of seeds to plant, then the seeds will be too crowded together; each plant will have to compete for the same resource (like water) as the other plants in the field.

Therefore, by using planter calibration, you can ensure that you use the correct amount of seed to ensure that your crops has an even stand of plants. The number of plants that you would like to grow in your field is referred to as your target stand. Your target stand is the goal for your planting effort.

How to Set the Right Seed Rate

For instance, many crops requires a target stand of 60 plants per square meter. However, not every planted seed will germinate and grow into a plant. For this reason, you must calculate the amount of pure live seed for your area.

The pure live seed calculation accounts for the germination of the seeds as well as the number of seeds that is pure (as opposed to being weeds or defective seeds). Should you not calculate the pure live seed for your field, then you will not know how many plants will emerge from the soil. Another factor that will impact how much seed is required to achieve your target stand is the thousand-seed weight of the seeds.

The thousand-seed weight is a measurement of the weight of a thousand seeds. Thousand-seed weight will impact how many seeds are contained within a single kilogram of seed. For example, if the thousand-seed weight of the seeds is low, then more seeds can be contained within a single kilogram.

In contrast, if the thousand-seed weight is high, then few seeds will be contained within that same kilogram. In either case, you can find this information on the tag of the seeds. Another factor that will impact the rate of seed that you must use to plant your fields is the row spacing of your field.

The row spacing will impact the distance between rows in your field. If you make the rows narrow in your field, then more plants can be planted into the field compared to when the rows are space further apart. Therefore, you can use calibration tools to calculate the number of seeds per meter or per foot of row spacing in your field.

In order to determine the total amount of seed that is required for your field, you can utilize the following equation: area of field x seed rate (per unit area). The area in question should be the harvested zone of the field, but you should subtract the area that is occupied by headlands. Furthermore, to account for any potential issue with even seeding, you should add 10% to the total amount of seed that is calculated for your field.

Finally, depending on the methods that you use to plant your fields, you may require a different rate of seeds altogether. For instance, air seeders and no-till openers may require more seed than field methods that dont have to contend with existing crop residues, and field methods may require different amount of seed depending on the condition of the field. Some common errors that may occur during planting relate to the characteristics of the seeds as well as the characteristics of the soil in which they are to be planted.

For instance, if the topsoil in your field is dry, then you may experience a drop in the emergence of your planted seeds. As a result, if you plant your field with a heavy lot of seeds, you may end up with too many seeds planted into the field. Such errors can be avoided by performing calibration calculations prior to planting.

For instance, if the germination rate for the seeds is likely to drop by 5% due to the dryness of the soil, the calculation of the rate at which you should plant your field may indicate that you must increase the rate of planting by 10%. Another way to accelerate the starting of the planting process is to use presells for the field. Presells indicate the settings for the field that other farmers that have similar conditions in their fields have pre-set.

For instance, you might set up your field with no-till planting methods into cold soil; a preset might have been made for this situation and could save you time in establishing your setting for the field. Similarly, reference tables can also be used to assist you in the planning process. Reference tables indicate the amount of seed rate at which you should plant your field based off the size of the seeds and the spacing of the rows in which the crops will grow.

For example, if the soil into which you are planting your seeds is firm and moist, a shallow rate of planting with minimal buffer can be establish. However, if the soil is cloddy, deeper seed openers may be required to plant the seeds into the soil. Another group of factors that relate to successful planting is timing and moisture in the soil.

For example, you should plant into the moisture in the soil rather than planting into the field based on a calendar date for planting. If you plant into the soil that is too cool and moist with seeds that have low rate of germination, the result will be a thin stand of plants. Residue that covers the soil can retain the moisture that evaporates from the soil; however, it can also lead to soil crusting.

Soil crusting can prevent the seeds from emerging from the soil. Furthermore, you can check the row at a time that is being planted in your field to ensure that the rate at which the planter drops the seeds is correct. Furthermore, catch tests can help to confirm the meter setting of the planting field.

While the information that is calculated during the calibration of your field will help you to determine the amount of seed to plant into each field, fields are variable in their requirements for crops. For instance, different areas in the field may receive moisture at different rates. Additionally, some areas of the field may be planted using a variable rate zone.

After planting into your field, you should walk the field three days after planting to determine the amount of live seedlings per meter of field. If there are thin spots in your field, you should note the soil texture within that thin spot in the field or the amount of residue present on the soil. If there are thick spots in your field, you should adjust the meter at which the field is planted to reduce the amount of seeds that are planted into the field.

This process may need to be repeated within the field to achieve accuracy in your planting rates. One tool that can make establishing the rates for your field is to use a planter rate calculator tool. This tool allows for you to input information regarding the thousand seed weight of your seeds, the target stand that you would like to produce with your crops, and the row spacing of your field.

Based upon these three variables, the calculator tool will provide you with the pure live seed, the establishment rate, the recommended seed rate for your field, and the total load of the seeds that are required to be planted into the field. These figures can be printed so that you can utilize them when you are planting into your field. Furthermore, if you perform the calibration process correctly, your field will contain an even stand of plants; an even stand of plants can lead to more successful growing season for that field.

You should of checked the tool more than once.
