My personal experience with high sodium soil

Remediating Salts – Personal Experience One of the known benefits of applying gypsum is displacing sodium (Na) in the soil with calcium so that it can leach below the root zone with irrigation or rainfall. Why is sodium bad for plants? Most people are aware of the damage and corrosive...

Can gypsum be applied with other fertilizers?

Gypsum (calcium sulfate) is a product that supplies the crop in the soil with a soluble and available form of calcium (Ca2+) and sulfur (SO42-). If these forms are deficient in soil, then crop productivity and soil will benefit if gypsum is applied. Today gypsum is sold either as ag-gyp...

Learn more about the benefits gypsum has on soil structure

   What are the benefits of applying gypsum? Improves Structure. Gypsum, and particularly its calcium component improves soil structure. Soluble calcium (calcium in the soil water) enhances soil aggregation and porosity to improve water infiltration. And soils that have too much sodium or too much magnesium relative to calcium can...

The benefits of achieving optimal soil health

I have been thinking a lot lately about soil health and its ability to sustain crops. Sure we know fertilizer and water are important as well as applying good management practices. But I believe there is more to a soil’s potential that is directly tied to optimizing soil health.  And...

Best practices for spring planting season!

The term best management practices (BMPs) can be applied to practices that maximize yield or practices that promote sustainability. These practices do not always share the same exact goals, however there is growing momentum and science that says you can be successful with both. Regardless, as growers are planning their...

Gypsiferous Soils: what they are and why you shouldn’t worry

I’ve known that calcareous or calcite soils exist across the world.  These soils are located in arid environments where insufficient rainfall fails to leach out the calcium carbonates.  We have a farm in Northeast Nebraska in which the soil is calcareous.  Lime flakes are very common on the soil surface...

The Myth of the Calcium to Magnesium Ratio

When you are involved in soil fertility, you sometimes hear people talk about a ‘calcium to magnesium ratio’.  A few agronomists follow this theory however many are skeptical of its value.  The theory is that for optimal crop production these two nutrients need to be in balance in the soil....

Can soil degradation be reversed by gypsum?

One of the concerns today is that soils are being degraded by intensive agricultural production, salinity or contamination.  Soil degradation can be generally defined as a decline in soil quality caused by its improper and unsustainable use. Soil degradation is slowly becoming a serious global problem and is exacerbated by...

What is soil?

A pretty basic question for the ground under our feet.  Plus, Dr. Dan Davidson explains Calcium Compartmentalization below. What is Soil? By Dr. Dan Davidson, Agronomist & Farmer When you pick up a hand full of soil did you ever think about what it contains? Soil contains minerals, organic matter,...
