Cleaning of Seeds – The Process

Wednesday, August 5th, 2015

If you think that the cleaning of seeds is a tedious process, then there is an alternative for you. You can always choose a professional help. However, if you are trying to do the cleaning in your farm, then you need to know about the process of cleaning. Here are the steps described for you.

Pre conditioning and Pre – cleaning

The seed which will be graded or treated needs to be properly cleaned and conditioned. The seed appendages and the other materials need to be removed from it. You can do this in your farm by using equipments like scalpers.

Basic seed cleaning

When you have completed the pre cleaning, you need to clean them once more. This is known as basic cleaning. In this step, the broken and the rotten seeds are also removed, in addition to any impurities which have been missed in the first step.

Basic principles of seed cleaning

The seed size and the weight are considered for the cleaning of the seeds in the cleaning equipment. However, the basic principles which are used are aspiration, scalping and grading.

Aspiration of the seeds refers to the process in which light and chaffy seeds are removed from the group. This can be done by blowing them with the air blower and also the light dust and straw which are present.

Scalping refers to the process in which the particles which are larger than the seed size are screened out and they are separated in a vessel.

The grading of seeds means arranging them according to the size and quality. It can be done by dropping the small seeds through a hole and keeping the larger one on top. This helps in their proper handling and helps prevent wastage.

Equipments used for cleaning of seeds

The most common equipment which is used for the seed cleaning is air screen cleaner. The screen cleaners function similar to the blower but with a little difference. In the screen cleaners there are four levels which are used to screen seeds of four different sizes and separate them. The aperture size is specified for each crop in order to filter or screen better and the sizes can be changed if required.

Tips for proper cleaning and processing of seeds

In order to process your seeds in the proper way, there are some precautions that you should undertake. First of all, you should check the moisture content of the seed. You should also keep an eye on the seed bins, the elevators, the seed cleaners and the gunny bags.

Fodder Crops Defination

Saturday, May 25th, 2013

The U.S. Department of Agriculture estimates that more than half of all agricultural land in the United States is used to produce fodder. Fodder is an agricultural term for animal feed, and fodder crops are those plants that are raised to feed livestock.

Common grain crops that are grown for fodder include corn, oats, millet, barley, sorghum, wheat and soybeans. Some of these crops, such as corn and wheat, are obviously also grown for human consumption.

Forage is a fodder crop that is grown (or encouraged, such as grass) for grazing animals. Immature grain crops, grasses and legumes, including alfalfa, are common forage.

Silage is fermented grass and other crops that are fed to ruminants, such as cattle and sheep. Silage grasses (hay and straw, for example) are cut and stored for future consumption, such as winter feed.

The Food and Agriculture Organization of the United Nations (FAO) includes grasslands, or pasture, as a fodder crop even if the grass is not cultivated. Pasture is land set aside for free-range grazing animals, such as cattle and sheep.

The production of fodder worldwide requires enormous energy, and agriculturalists, conservationists, ecologists and others are realizing that the land and energy necessary to grow fodder to raise livestock can lead to an unsustainable system. Adopting green technology and reducing the consumption of animal products are recommended by some people and organizations.
