Corn School - Split Applying Nitrogen for Maximum Benefit

Paul Sullivan of PT Sullivan Agro Inc joins the Corn School to talk about nitrogen application in corn, and how to best apply for maximum benefits and maximum efficiency.

what brand of fertilizer you recommend?

[@chitekwe]

Interspersing corn (or crop rotation ) with legumes like beans or groundnuts will naturally add nitrogen to the soil.

Can you share your fertilizer plan over the period of corn from cultivation to harvesting

[@thomasl7164]

Hi I’m living in Thailand and I’ve just in the process of getting land to grow maize please can anyone let me know what I need to apply the fertilizer and what is the best fertilizer to use Thank you

[@victorvicente6356]

I recommend you to space the rows properly. Do not overload the field. Try to find a 14-14-16 NPK . After harvesting I would use a cover crop.

[@Bob-vw3ce]

Fakhab great point. Is there another alternative to nitrogen fertilizer or is it the only answer? I researching organic ways to mass produce corn and other crops.

[@RealAgricultureMedia]

Crops need nitrogen in the highest amount of all nutrients. Building soil nitrogen without commercial fertilizer can be done through growing green manure crops, adding manure or compost, using pulses or legumes in rotation, and time.

Thumbs Down for the use of herbicide...

[@18deadmonkeys]

The herbicide isn't sprayed on the food crop since the corn hasn't emerged. After establishment, weed pressure is not as much of an issue. Pull your head out of your liberal hippy ass and be thankful of modern agriculture for keeping you well fed at an affordable price.

So says the guy named Beto

Unless you are an organic farmer which is extremely hard to do on a large scale. Farmers have to #1 Spray a herbicide to kill weeds before planting a crop. Some herbicides kill growing weeds other types keep weed seeds from germinating for a few weeks. Then #2 before the crop gets too tall, spray a herbicide again to kill emerged weeds. Sometimes an insecticide or fungicide pass is needed. No farmer wants to use pesticides but its necessity to make a profit and provide cheap food. Over time these pesticides break down in sunlight or are broken down by micro-organisms. Some pesticides stay in the soil for longer periods of time which is why it's important to not use them near shallow water tables or running water. Also apply at specific times to protect pollinators. There is a time limit between applying a pesticide and harvest. Like "must apply no later than 60 before harvest. This is true for many fruit & vegitable crops. In NYS we have to be Certified Applicators to apply and buy certain pesticides. If everybody thought like you do there wouldn't be enough farmers to feed the world. Also many other countries don't have the regulations for safe food like the US does.

Yeah, you want to go out and hoe his weeds for him?
