Editor's Notes
- Synthetic fertilizers are the horticultural equivalent to fast foods Recent research shows that synthetic nitrogen destroys soil carbon and organic matter, which causes: Soil Compaction Shallow root development and weaker plants Loss of water holding capacity Soil runoff and erosion Excessive rapid plant growth, increasing risk of disease and pests Synthetic fertilizers and pesticides destroy soil biology, depriving the landscape of natural nutrient cycling and disease controls
- By restoring the natural biological activity to the soil: Soil structure is improved Rooting depth increases, resulting in stronger plants Water holding capacity is increased, reducing runoff and erosion Water use in decreased Natural nutrient cycling occurs, reducing the need for fertilizers Natural pest and disease controls are in place Overall health and resilience of the landscape is improved Maintenance is reduced
- Old Growth Forest – an example of an ecosystem that is functioning well, without any inputs. No one ever fertilized an old growth forest. Nature figured out how to cycle nutrients to plants long before chemicals came on the scene (about a billion years before!). Carbon is being sequestered, nutrients are being cycled and disease prevented by microbes in the soil. Ecosystem Service Benefits

- HAVE SOIL ANALYSIS DONE EARLY, AS PART OF THE DESIGN PROCESS Not just standard soil analysis – test for biology in the soil (the Soil Foodweb), permeability, compaction, etc.
- Healthy soil grows healthy plants Nature knows how to do it. The KEY is in the soil biology – the Soil Foodweb - which delivers the nutrients to the plants Once the existing soil biology is analyzed it can be balanced by adding whatever is missing. FACT: In 1 teaspoon of healthy soil there are more than a BILLION microbes

- Increased root growth – from 3” depth to 15” in 6 months documented This translates to reduced water use and reduced fertilizers. Increased Root Growth Water Use Reduction Reduced Inputs Reduce Runoff Fewer Diseases Increased Toughness and Resilience
- Increased root growth – from 3” depth to 15” in 6 months documented This translates to reduced water use and reduced fertilizers No toxic chemicals
- BPCP is Battery Park City Parks Conservancy where Biological soil management has been used since the 1990’s
- Evaluation for soil biology, chemistry, soil compaction, permeability, etc. Develop site-specific guidelines based on the individual project site, the needs of the client, the availability of products such as compost tea
- THINK OF THE WATERSHED A WATERSHED IS AN AREA OF LAND WHERE ALL THE WATER (SURFACE AND GROUNDWATER) FLOWS TO THE LOWEST POINT - IN OUR CASE, THE BAY. MIMIC NATURE - KEEP THE RAINWATER ON SITE REDUCE STRESS ON AGING STORMWATER INFRASTRUCTURE KEEP POLLUTANTS FROMBEING WASHED INTO THE BAY
- Rainwater catchment installation at Yoche Dehe Wintun Nation headquarters in the Capay Valley Large reservoir type water catchment
- Slow it – Sink it – Spread it Stormwater BMP’s: Green Roofs Bioretention Planters Bioswales Rain Gardens Detention Ponds Permeable Paving Constructed Wetlands
- AVOID MONOCULTURES - MIMIC NATURE GROW PLANTS THAT WILL PROVIDE HABITAT FOR BENEFICIAL INSECTS SUCH (the 3 B’S): BEES (NATIVE POLLINATORS) BENEFICIAL INSECTS BUTTERFLIES, ETC. GROW PLANTS THAT PROVIDE HABITAT AND FOOD SOURCE FOR BIRDS AND ANIMALS HEDGEROWS
- People need nature!
- USE LOCAL DROUGHT TOLERANT CALIFORNIA NATIVES WHEN SUITABLE NOT ALL NATIVE PLANTS ARE DROUGHT TOLERANT LEARN ABOUT NATIVE PLANT COMMUNITIES ALSO USE LOCALLY ADAPTED DROUGHT TOLERANT NON-NATIVE PLANTS Reduced water use, increased habitat, increased biodiversity
- LAWNS – ONLY WHEN NECESSARY! LAWNS FOR RECREATION, NOT DECORATION! LAWNS USE EXCESSIVE AMOUNTS OF WATER AND ARE NOT APPROPRIATE FOR OUR CLIMATE LAWN FACTS: 1000 SF LAWN CAN USE UP TO 8000 WHEN LAWNS ARE NEEDED 1000 SF OF DROUGHT TOLERANT LANDSCAPE USES BETWEEN ZERO AND 500 GALLONS OF WATER PER MONTH LANDSCAPING CURRENTLY ACCOUNTS FOR AT LEAST HALF OF ALL RESIDENTIAL WATER DEMAND ESTIMATES FROM THE US EPA INDICATE THAT AMERICANS SPEND ABOUT $25 BILLION/YEAR ON LAWN CARE. 1 HOUR MOWING (GAS) = 20 MILES IN A CAR AMERICANS ALSO SPEND OVER $1 BILLION AND APPLY ABOUT 67 MILLION POUNDS OF PESTICIDES TO SUBURBAN LAWNS EACH YEAR LAWNS ARE HIGH MAINTENANCE MOST LAWN MOWERS POLLUTE THE AIR LAWNS ARE MONOCULTURES, DO NOT CONTRIBUTE TO BIODIVERSITY AND HABITAT LAWNS HAVE A SHALLOW ROOT SYSTEM, AND ARE ONLY ABLE TO ABSORB 1/10 THE RAINFALL OF A FOREST
- One of the First LEED Platinum K-12 schools in the United States Included: Native butterfly garden Boulders for seating and climbing Bioretention planter for stormwater treatment Green roof
