This is a 5-part series (previous parts at https://croptechcafe.org) on the basic cation saturation ratio (BCSR) concept. Summary of Part 1 & 2 was that authors Bear, Graham, and Albrecht of the BCSR concept in the 1940s-1970s suggested narrow basic cation saturation ratios existed, and a balanced cation saturation of the soil’s cation exchange capacity […] Continue reading → 
As a reminder, you need to plan ahead to plant alfalfa in regards to herbicide rotation restrictions and soil pH management, so read my blog post from Fall of 2023 at https://croptechcafe.org/plan-ahead-to-plant-alfalfa/. After corn and soybeans, alfalfa is the most grown crop in southeast Nebraska. Based on satellite imagery and crop reflectance, USDA CropScape estimated […] Continue reading →

Summary of Part 1 & Part 2 is that authors Bear, Graham, and Albrecht of the BCSR concept in the 1940s-1970s suggested narrow basic cation saturation ratios existed, and a balanced cation saturation of the soil’s cation exchange capacity were needed, or […] Continue reading → 
As a reminder, this is a 5-part series including the development of the basic cation saturation ratio (BCSR) concept (read at https://croptechcafe.org), field research after development (today), expanded details on field research in Nebraska (Jan. 17), the most recent scientific consensus from two published literature reviews (Feb. 3), and my current recommendations related to the […] Continue reading → 
If you remember, I did a 10-part “micronutrients in soybean” column series in the Fall of 2020 that you can still read online at croptechcafe.org/soybeans. I decided to address another soil fertility topic series. This series is on the basic cation saturation ratio (BCSR) concept. It will be a 5-part series including the development, field […] Continue reading →
