Fertilizing corn is on the most essential and critical parts about growing corn. If you don't use the right type of fertilizer when you are growing corn, your corn won't grow right, it won't grow in as large of a quantity, and nor will it taste as good as it could of. When growing corn, you need to pick the right type of fertilizer. There are many corn fertilizers out there and the right fertilizer depends on a lot of factors, most important of which is soil type.
Fertilizing corn should be done on the basis of soil tests and yield goals. Corn requires approximately 1.25 lbs. of elemental nitrogen (N), 0.6 lbs. of phosphate (P2O5) and 1.4 lbs. of potash (K2O) to produce one bushel of grain corn. Every type of soil is different and has a different chemical make up that requires different fertilizers. You'll want to test the soil to find out its chemical make up and talk to your local seed and fertilizer store. They will have the right fertilizer to meet the needs of your soil. If you don't have the right one, you could very well kill the crop you are spending so much time trying to grow.
Additionally, there are many types of kits you can get that will measure the ph balance and chemical balance of your soil. Before going to the shop, test your soil with one of these soil tester kits to find out the right information about your soil so the shop owners can help you with your needs. When growing anything, iformation is important.
Nitrogen can be applied at anytime and soils with good nitrogen produces better crops. As mentioned before, the exact needs of your corn will depend on the type of corn you are growing. Nitrogen is very important to growing any type of crop. If you can't afford a special nitrogen right fertilizer, you can always try animal manure which contains a high level of nitrogen and other good chemicals that can help plants grow.
Starter fertilizer can be applied with the planter in a band to the side and below the seed. The recommended fertilizer rate should be safely applied 2 inches to the side and 2 inches below the seed. Under cool, wet conditions, starter fertilizer offers many advantages. These type of fertilizer will help enable your corn to germinate and mature properly. Remember not to over fertilize your corn. More is not better. If you add to much, you run the risk of overfeeding and then kill your corn seeds and plants. It's sort of like over feeding people- eventually they get too fat and die.
Corn is resilient but, like growing any crop, it needs the proper balance of soil nutrients in order to grow well. Ensure that you give your corn the right balance by getting the right kind of nutrients to it. Don't get any cheap products or any fertilizer. Growing corn like any other crop is a science and if you don't follow the science, you won't grow anything....period.
