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.

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

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.

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.

Breaking Ground: The Pros and Cons of Reduced-Till Farming

Cropaia

These soil organisms play a vital role in nutrient cycling, organic matter decomposition, and overall soil health. With reduced disturbance, their populations can flourish, contributing to improved soil structure and fertility. This can discourage adoption, especially in the short term.

Growing media – Properties, benefits and usage

Cropaia

Vermiculite holds moisture and nutrients well, reducing the frequency of watering and fertilization. Vermiculite is commonly used in seed starting, as a soil amendment, and in hydroponic systems, making it ideal for seedlings and young plants. Red ash enhances drainage and aeration, preventing soil compaction and improving root health.

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.
