Biochar for Lawns and Gardens: What It Does, What It Doesn't, and How to Use It Biochar has become increasingly popular among gardeners, farmers, and homeowners interested in building healthier soils. It isn't a fertilizer and it isn't a quick fix, but used correctly, it can be a genuinely valuable long-term investment in soil function — improving water retention, nutrient retention, microbial habitat, and soil structure over time rather than producing an immediate visual cha

When people think about growing a healthy lawn or garden, they often focus on what they can see—the grass, flowers, shrubs, or vegetables growing above the surface. Yet the most important part of the system lies beneath their feet. Healthy soil does far more than hold plants in place. It stores and supplies nutrients, provides structure for roots, stores and releases water, allows air to circulate, and supports the living organisms that make the entire system function. When t

The Soil Health Principles ​ The soil health principles are a set of guidelines used to manage soil to improve its biological, physical, and chemical function. They were developed by observing how healthy natural ecosystems maintain fertile, resilient soils. The soil health principles were not invented by a single person or organization. They emerged over decades of observation, research, and practical experience by farmers, soil scientists, agronomists, and conservationists

Keep the Lawn, Manage It Better Lawns provide places for children to play, pets to roam, families to gather, and neighbors to connect. A healthy lawn can reduce erosion, cool the landscape, absorb rainfall, and enhance the appearance of your home. The goal of regenerative lawn care is not to eliminate the lawn. It is to maintain a healthy, attractive lawn while reducing reliance on fertilizers, herbicides, pesticides, fungicides, and excessive irrigation. A lawn is a valuable

Most homeowners do not think of their lawn as part of a watershed. Yet every lawn, garden, driveway, and rooftop is connected to a larger system of streams, rivers, and lakes. A watershed is simply an area of land where rainfall and snowmelt drain to a common body of water. When rain falls on your property, some of it soaks into the soil, some is used by plants, and some runs across the surface carrying soil particles, fertilizer, pesticides, and other pollutants with it. The

Many homeowners would like to use fewer fertilizers, fewer pesticides, and less water, but they worry that making changes will leave them with a thin, weedy lawn. The good news is that regenerative lawn care is not about abandoning your lawn. It is about changing how the lawn is managed. The goal is to shift the lawn from a system that depends on purchased inputs to one that increasingly relies on recycling nutrients. Healthier soil is built by encouraging biological activit

Nitrogen Is Everywhere—But Plants Can't Use Most of It The air around us is nearly 78% nitrogen. Yet grass cannot absorb nitrogen directly from the atmosphere. Before plants can use nitrogen, it must first be transformed into plant-available forms by soil microorganisms. Certain bacteria capture nitrogen from the air and convert it into forms that can enter the soil food web. Other microorganisms continue the process, eventually producing nitrogen that plant roots can absor

Dr. Rattan Lal, an acclaimed soil scientist, researcher, and author. Dr. Lal has published hundreds of journal articles on soil ecosystems, effects of tillage, global food security, sequestering carbon in the soil, and more. In the early 1990s, Dr. Lal was a pioneer of the now mainstream idea that healthy soils are a defense against rising levels of carbon dioxide in the atmosphere, leading groundbreaking research in Africa and later in South America.
