The Agronomists, Ep 161: Compaction causes and rescue fertility with Peter Johnson and Marla Riekman

Real Agriculture

Not so, at least not when it comes to deep compaction impacts. Air pockets and macropores in soil structure help move water down the soil profile, and where water goes, so do the nutrients. Compacted soils restrict root growth, oxygen, and nutrient and water movement, ultimately restricting yield potential.

Guide to Potato Cultivation: From Planting to Harvest

Cropaia

Poorly drained, heavy clay soils retain excess water, which can lead to waterlogging, oxygen deficiency, and increased risk of diseases like tuber rot. In contrast, overly sandy soils with poor water-holding capacity can lead to water stress, particularly during the critical tuber bulking phase.

Nutrient deficiencies and their symptoms

Cropaia

Nutrient deficiencies can result from various factors, such as poor soil nutrition, imbalanced fertilization, inadequate soil pH levels, or other environmental stresses. To address hidden nutrient deficiencies and prevent more severe imbalances, regular soil testing and plant tissue analysis are crucial.

Understanding pH: Success Stories: Growing Sollutions to Soil pH Challenges

UnderstandingAg

Cropland to Pastureland As discussed in part 2 of this series, many conventional cropping practices acidify the soil unnaturally quickly. The reasons vary, but common culprits include excessive N fertilizer use and the loss of organic matter. Many of his soils have pH around 5.5, The western half of the fields pH rose from 5.8

Soil organisms – promoting soil health

Cropaia

Soil is a complex and dynamic system that supports life on earth. It is teeming with a wide variety of organisms, each playing a unique role in maintaining soil health and fertility. From bacteria and fungi to insects, worms, and other organisms, soil is a living ecosystem that supports the growth of crops and other plants.

To Reverse a Troubling Trend, Farmers Are Adding Rocks to Their Fields

Modern Farmer

Pre-cultivation, the region owed the healthy pH of its soils to the lucky coincidence of sitting atop a volcanic bed. However, the topsoil is powerless to counteract the acidifying effect of ammonia-based fertilizers. Rauch was worried about seeding, soil compaction and whether he’d end up with one giant gravel pile.

Addressing Compaction During the Regenerative Transition: Part 1

UnderstandingAg

Soil compaction is the most common problem that I have encountered on farms as I travel across the Midwest. It is so prevalent that it’s easy to forget that compaction is a symptom , not an inherent property of soil. Soil aggregates are the building blocks of healthy soil.
