How are soil tests correlated to plant uptake?

On Farmer Q&A, we previously answered a question about the difference between phosphorus soil test methods, but how exactly are soil test methods correlated to plant nutrient availability? Soil test correlation is the process of determining the relationship between plant nutrient uptake (or yield) and… Read More

What is the optimum pH for corn production?

The simple answer is a wide range of soil pH is suitable to produce corn. The key is to avoid significant acid condition – pH significantly below 6.0. Alkaline soil conditions – pH above 7.0 – can be quite productive for corn, but these soils… Read More

Macronutrients vs micronutrients, what is the difference?

All essential nutrients have a critical concentration – the minimum concentration required for plant growth. These concentrations vary from plant species to species. However, we can categorize 14 of the essential nutrients into two categories based on the minimum concentrations needed by plants. Macronutrients –… Read More

What are all the essential nutrients for plant growth?

First off, the criteria for a nutrient to be “essential” means all the following are true: Plant cannot complete basic functions or complete its life cycle without that nutrient. A deficiency can be corrected only by the application of that specific nutrient and not substituted… Read More

What happens when I plant corn in soil that is too wet?

A: The main issue is called sidewall compaction. Sidewall compaction is soil that is compacted and smeared in and around the sides of the seed furrow. Since there is no way to alleviate sidewall compaction after it occurs, yield is reduced due to limited root… Read More
