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
Ideas, information and insights from real farmers on effective crop nutrient management strategies.
Immobile nutrients, like phosphorus, are available from a smaller fraction of soil that is near plant roots known as the root surface sorption zone (right). The size of the root surface sorption zone is influenced by soil texture. Coarser textured soils have a larger volume… Read More
There is a common misconception that if a nutrient is mobile within the soil, it is also mobile or can be translocated within the plant. The mobility of a nutrient in the soil is associated with how much can be leached – nitrate or sulfate,… Read More
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
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
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
