Yara's Crop Nutrition podcast

Manganese, Mn, is important to photosynthesis in plants and can have a dramatic impact on your yield and profitability.  In this podcast, Dr. Steve Petrie discusses how Mn availability is driven by soil pH and organic mater, how to identify and diagnose deficiencies and toxicities and how to correct it for optimum plant growth and profits

Before we identified copper as an essential nutrient, we were using it as a natural fungicide.  Copper is essential in reproductive systems in the plant.  Copper deficiencies are not wide spread, but where there is a deficiency, it is hard to visually identify.  Copper effects the reproductive growth but not vegetative growth, therefore the plant may show good healthy growth but actually have a co...

Our next micronutrient in the series is Iron (Fe).  Sometimes agronomy is more art than science.  Fe diagnosis and application is one nutrient where this is the case.  Fe is key in the production of chlorophyll that helps our plants grow healthy and strong.  Dr. Steve Petrie discusses how we can understand plant available iron in the soil and how to determine Fe deficiencies and how to implement F...

Boron (B) is the first micronutrient that we will be discussing over the next weeks.  It is critical to the growth and health of crops.  It can be considered a "sister" nutrient to Ca because it is a component of plant cell walls and membranes.  Dr. Steve explains that recent research has shown that B aids in Ca uptake and visa versa. If you want to learn more about Boron please visit our web page...

On our third and final ATW on calcium, we talk about physiological disorders that are common in plants and how calcium aids in reducing or eliminating these common problems.  We also discuss how adequate levels of calcium may help plants fair better when the environment and weather are trying to stress them out.

Orchards can be an expensive investment.  This podcast discusses tips and practices to increase your success and long-term profitability. Our guests Tim Roos, Roos Tree Nursery , Tom Devol, Almond Board of California , and Yara's Peter DeBoer and Devin Clarke talk about the many variables and solutions that will help you establish your new orchard and maximize your profits. Here are some useful li...

This is part 2 of 3 of our discussion on Calcium.  In this episode, we discuss the 4 Rs for Calcium, what are the right sources, application timings, how much to use and where to apply it.

Crop Manager, Markus Braaten, joins us at the end of the 2019 season to put our results in perspective.  We have come a long way over the years and are optimistic that we will continue to improve our profitable yields in the future. There are many variables in farming, some are controllable and some are not.  Our plan at the beginning of the season needs to be flexible and changeable as the season...

Although Calcium is considered a secondary nutrient, Dr Steve Petrie explains that it should be one of the most important nutrients to consider.  Calcium is the 5th most common element in the earths crust and can be 2nd or 3rd most common element in plants.  Despite its abundance, we need to know how much is plant available so that the plant can take advantage of this important nutrient. To learn...

Dr. Steve Petrie discusses the 4 R's of Potassium: What is the Right Sources of K What is the Right Rate of K What is the Right Timing of K application What is the Right Placement of K If you have a comment, question or suggestion please click HERE .  We would love to hear from you.

Dr. Steve Petrie helps us understand what potassium is, what it's roll is in crop biology, and how to test for potassium.   If you have a comment, question or suggestion please click HERE .  We would love to hear from you.

Last week Dr. Steve Petrie taught us why Phosphorus is so important for plant health and production.  This week we dive in deeper to understand the 4 R's for Phosphorus: What is the Right Rate? What are the Right Sources? What is the Right Placement What is the Right Timing If you have a comment, question or suggestion please click HERE .  We would love to hear from you.

Phosphorus is a macronutrient that is responsible for energy transfer in the plant.  We discuss why we should worry about P, the different forms of P and how it interacts with the other nutrients attributes to overall plant health and productivity.  Next week we will dive into the 4 R's for Phosphorus.   If you have a comment, question or suggestion please click HERE .  We would love to hear from...

In part 2 of Soil pH, Dr. Steve Petrie talks about how pH affects the biology and chemistry in the soil, canning tomatoes, and how to change the soil pH to maximize soil health and productivity

Soil pH is a fundamental characteristic of soil.  It should be the first factor to be considered when learning about a soil.  In this first of two podcasts on soil pH, Dr. Steve Petrie discusses what pH is, how it is measured, why it is important to healthy soils.

This is part 4 of 4 where Dr. Steve discusses the four R's of Nutrient Stewardship. In this episode he will be discussing the final "R" of the Four R's in Nutrient Stewardship: The Right TIMING of application Once you know the right RATE, right SOURCE, and right PLACEMENT of fertilizer, you need to know WHEN to apply the treatment to maximize the crops use efficiency.

There are many reasons to optimize your irrigation: Increase nutrient uptake efficiency Control Pest, Fungi, and diseases Improve plant health and productivity Reduce nutrient leaching Environmental sustainability Conserve water Reduce pumping costs We discuss some of the common methods used to determine irrigation frequency and duration. Evapotranspiration and crop water demand Weather variabilit...

This is part 3 of 4 where Dr. Steve discusses the four R's of Nutrient Stewardship. In this episode he will be discussing the third "R" of the Four R's in Nutrient Stewardship: Using the Right Placement of nutrients. Once you know the right RATE and right SOURCE of fertilizer, you need to apply the nutrients in the right place to maximize the uptake to the plant.  

This is part 2 of 4 where Dr. Steve discusses the four R's of Nutrient Stewardship. In this episode he will be discussing the second "R" of the Four R's in Nutrient Stewardship: Using the Right Source/form of Nitrogen.  Some may believe that it doesn't really matter what form of N you use; that all forms are essentially the same.  But this is not true.  Dr. Steve talks about the different forms, f...

Right Rate   Four R's of Nutrient Stewardship is a framework that can be used to increase productivity, better utilize a nutrition plan, increase profitability and improve environmental sustainability.     Right Rate of application   Right source of fertilizer   Right place   Right time       In the next four podcasts, we will be discussing each of these separately.  Today we begin with the Right...

Dr. Steve's Agronomic Tip of the Week is about the three factors that determine crop yield: The GEM factors:   Genetics   Environment   Management   We discuss these three factors and how to increase the capabilities of each.  We also discuss 2 main management components:   Nutrient Management – specifically the Four R's   Right nutrient rate   Right nutrient source   Right nutrient application ti...

When it comes to the most effective nutrition plan, Liebig's Law of the Minimum states that yield is proportional to the amount of the most limiting nutrient, whichever nutrient it may be.  From this, it may be inferred that if the deficient nutrient is supplied, yields may be improved to the point that some other nutrient is needed in greater quantity. Director of Agronomic Services at Yara, Dr....
