Where Does Nitrogen Go During Composting?
A compost pile can contain nitrogen without having much immediately available to plants. Much of the nitrogen in fresh plant material is part of organic compounds. As decomposers use that material, nitrogen moves among different parts of the living system. Microorganisms need nitrogen to build proteins and grow. As they consume organic material, they may take up available nitrogen and incorporate it into their cells. This temporary storage in microbial biomass is called immobilization. The nitrogen has not disappeared; it is being held in living organisms. As microbial cells die, are consumed, and break down, some of their organic nitrogen is converted into mineral forms, including ammonium. This release is called mineralization. Some nitrogen may then be taken up by other organisms, remain in the material, change form, or leave the pile. The amount available at any moment depends on the materials and conditions. These are shifts among nitrogen pools, not a fixed sequence that every pile follows. A carbon-rich material can support microbial growth while also affecting how much nitrogen is available to those microbes. If usable nitrogen is limited, microbial growth and decomposition may slow. When you look at a compost material, ask both what it contains and where its nitrogen might be held as decomposition proceeds. What material in your compost might be holding nitrogen in organic form or in living decomposers? When microorganisms take up available nitrogen and incorporate it into their cells, what is happening?

Taste Is One Clue, Not the Whole Pattern
When we study an herb, it helps to separate what we can sense from what a tradition interprets. Taste is a direct observation. An herb may taste bitter, sweet, sour, pungent, or astringent. Traditional energetic qualities are another layer of description. For example, Ayurveda describes taste (rasa) and potency (virya) as distinct properties. Cold potency (shita virya) means the herb is considered cooling within Ayurvedic energetic language. It describes the tradition’s interpretation of the herb’s action in the body, not a literal drop in body temperature. For example a warming herb might help if you are chilled all the time. In that framework, bitter taste is associated with cold potency, but taste and potency remain separate qualities. Keeping these layers distinct helps us avoid assuming that one taste tells us everything about an herb, its fit for a person, or how someone will respond. We can record what we notice, identify the tradition behind an interpretation, and keep the person’s current pattern and response in view. How would you separate what a source says about an herb from what you sense? A known herb tastes bitter, and an Ayurvedic source describes its potency as cooling. Which is the careful interpretation?

What Can One Root Sample Tell Us?
When we lift a plant after harvest, some roots may come free while others break or remain in the soil. The roots we recover can show features such as their direction, branching, and thickness. The roots we recover show only part of the plant’s root system. Other roots in the soil extend beyond the area we dug, or grow deeper than we reached. Fine roots can also break or be missed when we lift the plant. So describe what you can actually see. “The recovered roots branched outward through this soil” is a bounded observation. “This plant has shallow roots” makes a claim about roots we may not have seen directly. The next time you pull a plant after harvest for examination (we should typical cut plants at the base and leave the roots in the ground), what root feature can you describe without assuming you have seen the whole system? A gardener lifts one plant after harvest, and many roots break during removal. Which conclusion does that observation support best?

False sense of reality
There's fake news, deep fake images, false sentiment, artificial intelligence, protein substitute and lab grown meat, soilless growing and factory farms. Are we entering the matrix? I've seen that Kellogg's rice crispy cereal, a snap, crackle and Pop family favourite, will no longer contain rice, to reduce costs. It wasn't a healthy option to begin with, now it's another multi national counting pennies.

When a Banana Meant Freedom
When the Berlin Wall opened on November 9, 1989, East Germans crossed into West Berlin. Over the following days, many visited grocery stores, buying bananas and other goods that had been difficult to obtain at home. How did something so ordinary become so meaningful? After World War II, Germany was divided between the Western Allies (US, Europe and France) and the Soviet Union. By 1949, West Germany had become a parliamentary democracy with a market economy, while East Germany became a Socialist state, governed by a Communist Party with a centrally planned economy (sound familiar NY?). West Germans enjoyed greater political freedom and consumer choice. East Germans faced restricted travel, limited political freedoms, and shortages of many goods. In 1961, East Germany built the Berlin Wall to stop its citizens from leaving for the West. Peaceful protests and growing demands for change helped bring about the Wall's opening in 1989. Germany reunited the following year. People weren't risking their lives simply for bananas. They wanted the freedom to travel, speak, and make choices about their own lives. As we observe Veterans Day in the US, this history reminds me that the end of World War II did not end the struggle over freedom. We honor all those who served, including the veterans of World War II and the Cold War, whose service helped shape the world in which these events unfolded. And that an ordinary banana can remind us that the decisions governments make eventually reach into the everyday lives of families. Sometimes history is easier to understand through a grocery bag than through a political speech.
