Annual Phosphorus Application and Long-Term Soil Productivity

Many of the soils in North America, and around the world, have available phosphorus (P) levels that are at less than the optimum level — where crops will respond immediately to applied P fertilizer applications.

Drip Fertigation: The Future of Higher Yields?

New research from the University of Illinois is revealing the impact of drip fertigation systems. 

Preparing for a Hefty Harvest...And Beyond

Record yields mean record nutrient removal. 

Banding Phosphorus as a Bandage for low-pH soils?

In certain climates, banded P is a more economical choice than lime for low-pH soils in wheat. 

Phosphorus Fertility for Winter Wheat

Planting wheat? Dorivar Diaz shares how phosphorus helps to increase yields. 

Direct and Residual Fertilization in Soybeans

Fertilizing based on crop rotation may bring higher yields. 

Nutrient Removal and Chemical Resistance: How Weeds Are Damaging Your Field

Managing resistant weeds is a challenge in and of itself. Knowing that weeds rob crops of key nutrients makes it even more important to control them.

Expanding the Nutrient Management Toolbox: Using Tissue Sampling

Tissue sampling alone doesn’t provide all the answers. Get the most out of your data. 

IPNI Guest Blog: Keeping Nitrate out of California Groundwater

Nitrogen fertilizer management practices are under intense discussion in California. 

The Gap Between Macros and Micros Is Smaller than You Think

Do you know the difference between macronutrients and micronutrients? There are fewer differences than you may realize. 

Scouting Soybeans for Deficiencies and More

Soybean problems may look alike, and require good scouting to diagnose properly.

Managing Leachable Nutrients

Wheat crops in wet areas may be suffering from nutrient deficiencies due to leaching. Find out why and how to best supplement those nutrients 

Reducing the Continuous-Corn Yield Penalty

Continuous-corn systems require intense management, as the yield penalty can be as much as 25 bu/ac.

Nutrient Management Is a Journey, Not a Destination

Soil temperatures continue to rise; unfortunately, the commodity markets are not showing similar trend lines.

Soil Fertility Important in Managing Soybean Cyst Nematode

Did you know solid soil fertility can limit damage done by soybean cyst nematode?

Boron: A Micronutrient that Requires Micromanagement

Boron is a critical micronutrient for many crops, but its potential for leaching must be considered.

Risk Management Begins with the Soil

The key to risk management is controlling what you can.

Cover Crops: Type Makes a Difference

Do you know what type of cover crop will work best for your fields?

Weather’s Impact on Nutrient Management

Balanced crop nutrition is essential for plants to withstand the stresses of changing weather patterns.

Plan Now for Effective Fertilizer Management

While fertilizer decisions may start with soil samples, other insights and considerations can help build a strong crop nutrition plan to ensure higher yields.

All About Phosphorus

Phosphorus is one of the three macronutrients essential for plant growth. It is required for the photosynthesis process, converting the sun’s energy into food for the plant.

Cover Crop Considerations

Cover crops can help farmers manage their soil and nutrients from year to year. But not all cover crops work for all purposes. Knowing what cover crops need, and what they give back to the soil, can help you in your decision.

Boron’s Importance in Plant Development and Growth

One of the micronutrients that is essential for crop health also happens to be one of the most deficient in the majority of fields: boron.

It’s Time for Some Crop Nutrition Decisions

There’s certainly a value to working proactively to avoid stresses before they’re apparent, especially when it comes to soil fertility.

Did the Cool, Wet Spring Cause a Head-Scratching Harvest?

Farmers all over the Corn Belt saw striped and pale corn this spring and into summer. How they addressed these signs of nutrient deficiency may have been reflected on their yield monitors this fall.

Thinking Small — With a Focus on Zinc

In farming, little things can add up to make a big difference. This is certainly the case when it comes to balanced crop nutrition. 

Nutrient Balance Plays Big Role in Balancing Land Value

With land prices the past few years skyrocketing, balancing nutrients in the field is more important than ever.
 

Fall Potassium Applications: Consider Crop and (Soil) Characteristics

Required by all plant life, potasium (K) plays a major role in photosynthesis, breakdown of carbohydrates, protein synthesis and disease resistance. Most importantly, it can activate at least 80 enzymes that regulate the rates of major plant growth reactions.

The Soil Fertility Checklist

When it comes to crop nutrition and your soil fertility plan, you need to make sure you’ve dotted your i’s and crossed your t’s.

Soybean Sudden Death Syndrome

With a name like sudden death syndrome (SDS), this soybean disease certainly demands our agronomic attention. But, while it’s serious, understanding SDS might actually make it less intimidating.

Evaluating a Soybean Fertility Program

Historically, many soybean fertility programs are based on the philosophy of “make do with what’s left.” But progressive growers are finding it’s important not to forget this crop’s primary job is to pull nutrients out of the soil, and that those nutrients need to be replenished.

Plan Now for Your 2014 Fertility Program

Even before the 2013 crop is in the bin, growers should begin putting thought into how they will proactively manage their 2014 fertility programs.

Good Options, Better Options: A Look into Soil Sampling

Soil sampling has adapted and evolved over time. As genetics, crop nutrition, equipment and precision ag technologies have matured, so has the need for more advanced soil sampling in the field.

The Sulfer Solution

Farmers and retailers who have been in the business for a while probably find themselves wondering why so much attention has been paid to the past several years. After all, sulfur used to pretty much take care of itself, supplied to plants by organic matter and deposited by rainfall.

Tips for Managing On-Farm Trials

While there certainly is no shortage of information available on how different crop inputs and solutions perform on research test plots around the world, there is no substitute for seeing firsthand how a new seed, chemical, technology or input will perform on your own land, with your management style.

Boron: A Key Consideration in High Yield Systems

As yield levels increase, so does the demand for nutrients not often considered as standard practice. This means that a high-yield system requires more attention be paid to micronutrients.

Is Population Growth Demanding More Aggressive Nutrient Replenishment?

Population dynamics, the impact of biofuels and land use and productivity are all a part of the equation in determining future fertilizer nutrient requirements.

What Your Next Physical Can Teach You About Corn Care

When an agronomist visits a field to diagnose a problem, it’s not unlike a doctor attempting to uncover the source of a patient’s discomfort.

How Plants Show Hunger

The relationship between soil chemistry and nutrient uptake can fluctuate just as much as the weather from year to year. With today's seed genetics, you may find some hybrids are great at optimizing a certain nutrient but wasteful with others.
