Role of AM Fungi in Agricultural Ecosystems

Today we are going to examine the role arbuscular mycorrhizal (AM) fungi play in providing phosphorus and other benefits to plants and the impact of chemical fertilizers on plant-fungi symbiosis. Nutrient Cycles You often hear about the P-cycle (phosphorus) or the N-cycle (nitrogen) and have probably seen all sorts of graphics demonstrating how these nutrients […]

Agriculture in Transition book cover

Book excerpt: Agriculture in Transition by Donald Schriefer

Agriculture in Transition is the last word on eco-farming systems from America’s “environmental agronomist” – Donald L. Schriefer. A pioneer in developing an awareness of the relation of tillage to soil fertility, Schriefer focused on three major soil basics – soil aeration, soil water, and soil decay – as the foundation of sound, productive agriculture.

Fungal growth covering the grain signals the completion of the initial culture (in a box).

Biological Inoculants for Soil Health

As part of efforts to improve the soils and quality and yield of produce at Tobacco Road Farm we have been utilizing a biological inoculant made from locally sourced microorganisms. This inoculant material is referred to as IMO (Indigenous Microorganisms). The techniques for IMO culturing come from the principles of Korean Natural Farming (KNF), an […]

Front cover of Science in Agriculture

Book excerpt: Science in Agriculture by Arden B. Andersen

In his book Science in Agriculture, author Arden B. Anderson sought to apply true, natural science to agriculture. Readers should gain a working knowledge of chemistry, physics, and plant biology as applied to agriculture; discover what weeds are communicating about your soil’s fertility needs; and learn how to design and implement a program to produce […]

Understanding Soil Carbon Dynamics

Carbon is an often overlooked, but very important com­ponent of the soil. We know how to manage nitrogen, phos­phorus and potassium for maximum production, and that micronutrients play a critical role in crop yield and disease resistance. Deficiencies can usually be corrected relatively quickly through the addition of soil or foliar fertilizer ap­plications. While soil […]
