1 Catch Crops

Catch crops are very important for the farmers in agriculture sector. These are also regarded as back-up plan for the growers. How? These crops are cultivated if the regular crop sown in the field fails. These are actually substitute crops for regular crops and sown late.

Also known as short season crops, a good example of catch crop is Millet. Vegetables are also good substitutes, if regular crop has failed, to cover maximum loss. Another purpose of catch crop is to prevent the minerals in the soil from being flash out.

These crops are grown in regular fashion and then preserved in succulent conditions in a tight receptacle to conduct partial fermentation. Crops that are included in Silage crop group are Corn, Forage grasses, Legumes etc.
