Get phosphorus in the ground this fall

The price and the timing are right

To say it’s been a wet fall is an understatement. In my experience, that means farmers in my area who practice zero or minimum tillage are more likely to cultivate a few acres to blacken up the soil – if they can get into their soggy fields.

That’s the perfect opportunity to band phosphorus while you cultivate. Because as a general rule, soil around here has low phosphorus levels. We’ve been mining the soil as we produce bigger crops without replenishing nutrients – especially phosphorus.

Some folks look at fertilizer as a cost of production. I like to look at it more as an investment in your soil. The more fertile, the more productive it will be in the future years.  In recent years we’ve seen dramatically increased nitrogen rates. I know farmers who use about double the nitrogen they were putting down 10-15 years ago, but phosphorus rates are only marginally up from the same time period.

Right now phosphorus is cheaper than it has been in a while – in fact this is the cheapest it’s been in the fall for the past five years. That’s due to an oversupply in North America after a wet fall last year followed by a very wet spring in the US.

If you’re going to till, I always want to see fertilizer go down at the same time. But if you’re going to till this fall, you’d be crazy not to put down some very reasonably priced P at the same time to give next year’s crop a better chance. This will keep the air cart lighter for next spring, will potentially get more acres per fill, and aligns with the 4R approach of right source, right rate, right time, and right place.

Every time there’s an opportunity to band nutrients, you’re doing a benefit to the soil, but it would be tough to put down enough fertilizer in a one-pass seeding system because of equipment limitations or potential seed burn.

How can you argue? Especially if:

1. You’re already planning to cultivate your land this fall.

2. Phosphorus prices are better than they’ve been for the past five years. (You can buy it and apply it instead of worrying about storing it.); and

3. You’ve been getting better yields that you haven’t been fertilizing for.

If you have questions about your fertilizer strategy and how phosphorus can improve your soil, contact your nearest Cargill location.

Brett is looking forward to using his knowledge on soil fertility and weed management to help find farmers practical solutions Brett grew up on a mixed family farm near Medora Manitoba, where at an early age he developed a passion for agriculture. Before attending university Brett worked on multiple farms including a 35,000 acre farm in Australia. After graduating from University of Manitoba with a Diploma in Agriculture in 2013, Brett gained a wide range of experience through working as a Sales Agronomist in the southeast and southwest corners of Manitoba, working as a Research Technician out of Melita, as well as running his own family farm. Brett joined Cargill in 2017 as a Market Development Agronomist. He is looking forward to using his knowledge on soil fertility and weed management to help find farmers practical solutions that will work best on their farm and working hands-on in the field. Brett wants to help you make the best decision for you and your crops!
