Crop Fertility


Comparing foliar and in-soil methods of applying nutrients

Field crops normally absorb the majority of nutrients from the soil through root absorption, but above ground plant structures, especially leaves, are capable of absorbing limited amounts of some nutrients. Because of this, most supplemental nutrients supplied to crops as fertilizer are applied to the soil, and soluble nutrients in the soil contact root hair surfaces, where they are absorbed into the roots and transferred to other parts of the growing plant for metabolic use.

Soil pH is the big elephant in the field

Across Western Canada there are roughly 20 million acres affected by low soil pH. To put this in perspective, this is more than all the land farmed in Indiana or the United Kingdom, and ten times all the farmland in the Netherlands. In Indiana, the UK and the Netherlands, the first thing a grower looks at on a soil test is pH.


Is your plant nutrition program healthy?

One of the most important things you can do throughout the season to help increase yield potential is to ensure your crops have adequate nutrition. You can check nutrient levels by working with your agronomist to take multiple tissue samples throughout the season (often in concert with soil samples) to determine if critical nutrients are lacking.


Germany's K+S confirms takeover proposal from Potash Corp

German potash producer K+S said on Thursday it has received a takeover proposal from larger Canadian fertilizer producer Potash Corp of Saskatchewan Inc, potentially marking the start of a new takeover saga in the industry.

Mosaic announces new environmental sustainability targets

The Mosaic Company released its 2014 Sustainability Report titled, "Leading with Purpose," which outlines the company's sustainability progress and new 2020 sustainability targets. The company's sixth Sustainability Report discloses information on 95 Global Reporting Initiative (GRI) indicators and is prepared in alignment with G4 Core Sustainability Reporting Guidelines, which have an increased focus on materiality.


Assessing available N from fall- and spring-applied N

Excessive rainfall and the resulting ponding, flooding, or saturated soils have likely caused some loss of applied and soil-derived nitrogen (N). Nitrate-N (NO3-N) is the form of N most likely to be lost from the crop root zone, either to tile drainage, groundwater, and/or into the atmosphere (via denitrification). Ammonium-N (NH4-N) is not subject to N loss mechanisms when incorporated into the soil.
