Agriculture and the Natural World
This is an exploration of agriculture and how it relates to the environment.  Whether you call it agroecology or eco-agriculture or permaculture these all offer alternative approaches to industrial agriculture that are far more sustainable. This page will highlight good, bad and neutral news related to environmental, economical and socially sustainable agriculture.

New Teaching Tool, "Plant Nutrition 1: Membrane Transport and Energetics, Potassium Nutrition, & Sodium Toxicity"

New Teaching Tool, "Plant Nutrition 1: Membrane Transport and Energetics, Potassium Nutrition, & Sodium Toxicity" | Agriculture and the Natural World | Scoop.it

In this first of three lessons spanning the topic of Plant Nutrition, we examine primarily the energetics and mechanisms of nutrient uptake and transport. These processes are particularly well illustrated by an examination of the essential nutrient potassium (K), and the closely related element sodium (Na). We also examine the challenges associated with providing plants with sufficient K to support vigorous growth, and the detrimental effects of sodium accumulation in soils. Finally, we examine efforts to improve the salinity tolerance of crop plants. (Co-authored with Michael Blatt).

Mycorrhizae on the History Channel


Via Jean-Michel Ané
Darin Hoagland's insight:

Nice explainer video about the importance of Mycorrhizae and plant health.  Increasing agricultural food supply means maintaining good soil health and mycorrhizae are a big part of making soil nutrients to available plants.  Replenishing depleted soil especially after anti-fungal applications and reducing the myorrhizae application cost to farmers are key.
