7 Soil Health is Vital to Sustainability Soil Health - the continued capacity of the soil to function as a vital living ecosystem that sustains plants, animals, and humans ( Source: USDA NRCS, 2012; Soil Renaissance 2014) 70 percent of the world s topsoil is gone. Food production must increase by 70 percent between now and 2050 to feed the growing world population. 40% OF SOIL USED FOR AGRICULTURE AROUND THE WORLD IS EITHER DEGRADED OR SERIOUSLY DEGRADED Each year we lose about 100,000 km2 (over 24 million acres) of cropland due to soil erosion. If we continue on the same trajectory, we will produce 30 percent less food over the next 20 to 50 years. Source: United Nations Global Opportunity Report (2017), FAO estimates 7

8 Soil Health is the Foundation Soil is a dynamic interface between living things, air, rock and water. Soil includes the active interactions between its parts--physical, biological, and chemical. The soil s function, as a foundation of the ecosystem it is part of, depends on its characteristics. Source: Comprehensive Assessment of Soil Health Cornell Framework,

9 Healthy vs Unhealthy Soil Healthy Soil Has: Good soil tilth Small population of Sufficient depth plant pathogens and Good water storage insect pests and good drainage Large population of Sufficient supply, but beneficial organisms not excess of nutrients Low weed pressure Unhealthy Soil Has: Soil compaction Poor aggregation Weed pressure High pathogen pressure Low water and nutrient retention Salinity and sodicity Heavy metal contamination Source: Cornell University Soil Health Manual (2016) bit.ly/soilhealthtrainingmanual 9

10 Managing Soil Health Managing for soil health (improved soil function) is mostly a matter of maintaining suitable habitat for the myriad of creatures that comprise the soil food web. Manage more by disturbing soil less Diversify soil biota with plant diversity Biodiversity Keep a living root growing throughout the year (cover crops) Keep the soil covered as much as possible A fully functioning soil produces the maximum amount of products at the least cost. Maximizing soil health is essential to maximizing profitability. Source: Natural Resources Conservation Service. Backyard Conservation NRCS, 10

11 The Importance of Mycorrhizal Fungi

12 What are Mycorrhizal Fungi? Myco-rhiza, which literally means fungus-root, was coined in Biologists think mycorrhizae have been around for 600 million years 1 Earliest fossils of mycorrhizae date back to 460 million years ago 1 Symbiotic fungi Benefits on soil health-accumulation of soil organic matter and stabilization of soil aggregates 2 80% of all plants on earth form a root-mycorrhizae association 1 Source: 1 Valent U.S.A. LLC 2 Comprehensive Assessment of Soil Health Cornell Framework,

13 Pronouncing it! 1. Mycorrhiza-this is the singular noun MY-CO-RYE-ZA We will be studying the structure of a mycorrhiza. 2. Mycorrhizae this is the plural noun of mycorrhiza MY-CO-RYE-ZAY There are many species of mycorrhizae. 3. Mycorrhizal this is an adjective that describes something MY-CO-RYE-ZAL Fungi, hyphae, etc There are multiple species of mycorrhizal fungi. 13

14 What do Mycorrhizal Fungi Do? Mycorrhizae protect plants from environmental stressors such as drought and nutrient deficiencies. o Mycorrhizae can release tightly bound nutrients, making them available to the plant. Mycorrhizae form a network of hyphae, extending from the root system. o Those hyphae reach nutrients and water outside of the root absorption area, and also in small pores within the soil. Mycorrhizae are composed of: 1. Spores dormant in the soil, producing hyphae when roots begin to grow 2. Hyphae find and form association with roots to expand into the soil for nutrients and water, beyond the root area 3. Vesicles stores resources until needed by the plant 4. Arbuscules transfers resources gathered by hyphae to the plant 14

15 How Mycorrhizae Interact with the Plant Root Mycorrhizal mycelia (a mass of hyphae) act as an extension of the plant root and more Mycorrhizal mycelia expand the surface areas of roots 50X to find and transport more nutrients and water to the plant which are outside of the root depletion zone. Mycorrhizal mycelia can convert non-bioavailable nutrients into bioavailable nutrients.

17 Soil Health Challenges Just a teaspoon of healthy soil may contain several miles of fungal hyphae needed for optimal growth. More intensively managed lands often lack adequate populations of mycorrhizal fungi. Typical modern agricultural practices that reduce the biological activity of mycorrhizal fungi in soil: Tillage or any soil excavation Disruption of soil damages or reduces naturally occurring mycorrhizae population Rotation to crops that do not support mycorrhizae will reduce populations of mycorrhizae because there is no host crop to survive on Soil fumigation Once lost from a farm s soil, arbuscular mycorrhizal fungi populations are very slow to recolonize, due to the fact that these fungi do not disperse spores in the wind, but grow from root to root. 17

18 MycoApply EndoMaxx Providing Better Crop Performance Microbial additives have been used commercially in global agriculture for more than 120 years, but interest in this market is increasing. Microbial replenishing of soil is no longer an ecofarming niche occupation, but a way to save billions of dollars. United Nations Global Opportunity Report (2017)

19 What is MycoApply EndoMaxx? Building Better Crop Performance MycoApply EndoMaxx contains four species of mycorrhizae fungi that colonize a plant s root system to promote root mass expansion, nutrient efficiency and drought tolerance for optimal plant health, performance and yield. Root mass expansion expands vascular network beyond roots and into soil by up to 50 times Nutrient efficiency absorbs and transports soil nutrients directly to the root including tightly bound nutrients such as phosphorus and micronutrients Drought tolerance stores resources until needed by the plant and improves water availability and transport OMRI listed and NOP compliant to fit both organic and sustainable production 19
