Soil Quality - Introduction to Soils — Start Farming Soil health is the foundation of productive farming practices. Fertile soil provides essential nutrients to plants. Important physical characteristics of soil-like structures and aggregation allow water and air to infiltrate, roots to explore, and biota to thrive. Diverse and active biological communities help soil resist physical degradation and cycle nutrients at rates to meet plant needs.

From E-Learning to We-Learning The corporate training industry is undergoing some major changes. Over last few months we have been involved in many discussions with organizations about the tremendous needs to build, manage, and formalize their social and collaborative learning programs. This is being driven by many factors: the slowing economy, the "always-connected" nature of the workforce, and the explosion of social software tools and platforms now available. In many ways, this transition is very similar to the last "big thing" to hit corporate training - the "e-learning" era.

Rocks and Soils Wherever you are now, there are rocks below you. Even if you are standing on the beach, digging in the garden, swimming in the sea or rowing across a river, there are rocks somewhere beneath your feet. There are many different rocks, from soft mudstone and crumbly sandstone to hard granite. Some rock splits in sheets - like slate. Some rocks are rare and valuable - like gold and diamonds.

Nature - Tardigrades: Water bears in space 17 May 2011Last updated at 02:46 By Emma Brennand Reporter, BBC Nature Tardigrades are microscopic animals commonly known as water bears In 2007, a little known creature called a tardigrade became the first animal to survive exposure to space. It prevailed over sub-zero temperatures, unrelenting solar winds and an oxygen-deprived space vacuum. On Monday, this microscopic cosmonaut has once again hitched a ride into space on the Nasa shuttle Endeavour. Its mission: to help scientists understand more about how this so-called "hardiest animal on Earth" can survive for short periods off it.

Glyphosate, Roundup, GMOs and the microbiome part 1: crowdsourcing literature For many reasons I have been interested for the last few years in how agricultural practices affect microbiomes. For example in regard to crops, how do farming practices affect the microbiomes of the plants, the microbiomes of the soil and area around the plants, and the microbiomes of organisms (including humans) who make use of the plants? I won't go into all the detail right now for why I am interested in this topic but for some examples of my work in this area see The microbes we eat abundance and taxonomy of microbes consumed in a day’s worth of meals for three diet types and Structure, variation, and assembly of the root-associated microbiomes of rice. Anyway, the reason I am writing this now is that tomorrow I am "testifying" to a NRC Committee about this topic and some related topics. The presentation will be shown live online (register here).

Common as Dirt This year is the International Year of Soils. This may not sound as catchy as previous international years, variously devoted to such topics as Water Cooperation, Sustainable Energy, Forests, Biodiversity, and Rapprochement of Cultures–but the truth is that the United Nations could hardly have made a better pick. Given that we can’t survive without it, it’s amazing how few of us truly appreciate dirt.
