Yara's Crop Nutrition podcast

As temperatures rise, our crops can succumb to stress that might have detrimental effects on our yields and quality this year and next year. Permanent Crop Manager, Devin Clarke grows our knowledge with some nutritional strategies that can mitigate these stresses and keep us on track for successful harvests.  Calcium in the right form, applied at the right time and rate can help our trees reduce t...

This is our continued discussion with David Chaffin, Digital Agronomist, and Dr. Steve Petrie from last week.  Corn yields have improved over the past decades, but we still can achieve more.  Dave helps us understand some of the biggest innovations that are on the horizon and how you can begin implementing them for higher yields and profits.  

Yara's Market Development Managers, Dr. Trey Cutts and Markus Braaten help us understand how Sulfur and Nitrogen, working together, can increase crop growth potential and farm profitability. Plants use N & S together to build proteins and DNA to assure top yields N & S are needed in a balanced ratio, depending on the specific crop Excessive amounts of one means a deficiency of another How can we a...

Yara Digital Agronomist and corn expert, David Chaffin, joins Dr. Steve Petrie to discuss the agronomics of corn.  In the last 100 years our planted corn acres haven't changed much, but our yields have increased dramatically.  In the first part of two podcasts, we talk about some of the things that attribute to the higher yields and the potential for continued improvement.

Last week we talked about some toxic elements.  This week we dive into some essential nutrients that can also be toxic.  We specifically talk about: B Cl Fe Mn

There are some toxic elements (non-essential elements that are toxic to crops)that are common in agricultural settings.  The two that we will discuss in this episode are Aluminum and Sodium: how these effect the soil and plants.

As we continue to understand proper foliar nutrition, we should understand the RIGHT RATE and the RIGHT TIMING for these applications to have the desired results without damage to the plants.  It is also good to know about some of the important additives that can increase the efficacy of these treatments. Jimmy Ridgway joins Dr. Steve to help us grow our knowledge.

Foliar nutrition can complete a great nutrition program.  Some advantages of using foliar applied nutrition with a base fertility program are: Correct nutrient deficiencies as determined from soil or tissue tests Strengthen damaged crops Speeds up growth Stimulate root uptake Provide nutrient efficiency Crops benefit in two manners by the foliar application of nutrients: by the rapid influx into t...

Dr. Steve Petrie helps us understand what free lime in soil is and how it can effect some nutrient availability, which nutrients to worry about and some strategies when dealing with free lime. To learn more: Yara US Yara Canada Yara

What is Cation Exchange Capacity and why is that important when developing and executing a complete nutrition plan for you crop and field?  Dr. Steve Petrie helps us understand what cations and anions are, how they attach to soil particles and why that is important to your fertility plan. Here is a great video created by Learning Games Labs that simplify cation exchange process.

Dr. Steve Petrie helps us understand how soil pH can help improve nutrient uptake and overall crop health.  He answers the following questions: What is pH and how do we measure it? Why does soil pH matter? Is there a best pH for my soil? Why is low or high pH bad? How do we correct adverse soil pH? Is there better forms of fertilizer that can be used to help correct adverse pH?

Shay Myers is the General Manager of Owyhee Produce , a third-generation family farm and one of the largest vertically-integrated produce farms in the Nation.  Shay joins Brady Stover, Yara Sales Agronomist, and Scott Warr, Digital Farming, to discuss what it takes to be a family farm in today's society.  He talks about the challenges they face with the current virus situation and how they plan to...

Soils are the medium for plant growth.  Soils have physical, chemical and biological properties that should be understood to maximize the genetic potential of the plants and optimize profitability and sustainability. The physical characteristics we talk about are:   Texture Structure Water Holding Capacity  Find out what soil you have using the NRCA's Soil Survey maps Learn how to make a soil text...

What is the correct process to take a plant sample?  We talk about how, when, where, what part of the plant and common mistakes that can be avoided.  Plant analysis can be an effective way to understand many nutrients and the ratios of those nutrients.  Many times these deficiencies can be detected before the plant shows visual signs.  However there are some nutrient analysis that are not as relia...

Join Trey Cutts, Crop Manager at Yara North America, and Dr. Bobby Golden, Associate Professor at Mississippi State University, as they delve into the intricacies of Nitrogen Management. With so much history and knowledge in using Nitrogen as a fertilizer, why are there so many questions out there about it's management in agricultural production? From what nitrogen source to use, to rates and timi...

Dr. Steve Petrie discusses why we should add plant analysis to our tools for plant growth and financial optimization.  Soil testing is a predictive tool, while tissue analysis is a monitoring tool that helps us understand what the plant is actually using throughout the season. Using each can help us understand the biology of the plant and should not be used exclusive of each other.  In this first...

In the third of our three part series on soil samples, Dr. Steve Petrie talks about the interpretation of the lab results: How reliable is the database? How many trials are in the database? Are current varieties in the database? How is field variability addressed? In the end there is no substitute for professional judgement and knowledge of field history.

Soil Samples are important to understand your nutrient balance in order to develop an effective nutrient management plan. This is the second of three podcasts that help us with soil samples. In this podcast Dr. Steve Petrie teaches us about lab analysis: How do we select a lab? What should we know about the different analytical processes? What is the expected turn around time? What tests are avail...

Soil Samples are important to understand your nutrient balance in order to develop an effective nutrient management plan. In the next three podcasts we discuss how to collect a sample, Lab analysis and Interpretation of these results. In the first of this series, Dr. Steve Petrie talks about the proper way to collect these samples.   When should we collect the samples? How deep should we go? How f...

Cl rarely deficient in nature but it is essential in plant nutrition.  It is found in the soil as anion and plays two roles in plant nutrition: Cl is integral to the process in which water is split, thus releasing H+ ions and O2 gas Cl is a mobile anion within the plant where is functions in osmoregulation affecting cellular expansion and stomatal opening and closing. It also functions as a counte...

Yara's Turf and Ornamental Crop Manager, Neil Mayberry has a discussion with David Robinson, Senior Director of Golf and Grounds for Marriott International.  David manages golf courses around the globe and sees a wide variety of turf, weather, and diseases. Weather patterns and diseases are ever changing and hard to predict and a superintendent needs to be dynamic in his/her management. David teac...

Nickel is the least understood micronutrients and rarely found deficient in most crops.  Despite this, serpentine soils may have a much greater Ni concentrations and may be toxic.  There are studies that show there can be deficiencies in pecans.  Dr. Steve talks about Ni and how, like Molybdenum, it is essential in N metabolism.

Molybdenum is the only metallic micronutrient that is less available on low pH soils.  Mo is essential for nitrogenases enzyme in N fixation by legumes and for nitrate reductase and for Pollen production. Because Mo is associated with N, deficient plants may appear to be N deficient.  Dr. Petrie talks teaches us which crops are sensitive to Mo deficiency, how to recognize it and how to treat it.
