If you’ve ever wondered how many gallons of rain water fell on your roof or your property, here is some rain math I whipped up this morning to figure it out after a weekend of heavy rain:
( ______ square feet X 144 square inches ) X _____ inches of rain / 231 cubic inches per gallon = _______ gallons of rain!
Knowing how much rain you could collect from a barn or shed roof is important information to know, especially for a farm with irrigation needs. Just like the abundance of free solar energy, rain water is one of those amazing natural resources that literally hits us in the face while we barely even think about it.
Knowing what natural resources are freely available to you is the first step toward harnessing and managing those resources into more sustainable living. This rain math tells me what size cisterns and pumps I would need. It also shows me how much municipal water we can save and understanding our impact on the Stones River watershed.
One of the most important organic cultural practices I use on the farm is inoculating crops with mycorrhizal fungi. The photo above shows an application on one of 100 organic hop rhizomes we just planted. The symbiotic relationship between this fungus and plant roots is essential for healthy soil and plants. It’s also the secret that all of the current world record pumpkin growers don’t want you to know.
How it works: The fungi is naturally occurring in healthy soil all over the world. The largest living organism on the planet is a 2,400 year old 2,200 acre mycelial mat discovered in August 2000 in Oregon’s Malheur National Forest. Mycorrhizae are the very life of our planet’s soil creating a network of microbial life that naturally mitigates disease, nutrition and water concerns in the cultivation of crops. Mycorrhizae reduce the use of tilling, irrigation and chemical inputs in aggriculture. It also helps sequester carbon and is a key environmental relationship in our survival on the planet. Many organic farmers who use mycorrhizal fungi never have to water their crops even during drought. You can see several of these side-by-side comparisons pictured here online that illustrate exactly why.
Conventional farming methods using chemical fertilizers, pesticides and tilling are slowly destroying this natural relationship in favor of predictable short-term outcomes from dependence on expensive inputs that often hide destructive and unsustainable results.
Perfect design: Mycorrhizae are basically a mushroom (mycelium) that feeds off the plant’s sugars through its root system. What the fungus does in return for plants is truely amazing: it takes nutrients and water from the soil and feeds the plant by becoming a huge network of extended roots. The fungi is also what breaks down rocks and minerals for plants. It also makes plants more drought resistant as their access to soil moisture is more than ten times that of non-inoculated plants. One application to roots during transplanting or seeding lasts the entire life of the plant, and the results are indisputable.
There is a lot of simple research showing plants do much better using mycorrhizae than using conventional fertilizers. Here is a 6th grader’s science fair project using Fungi Perfecti’s MycoGrow (what we use at Half hill Farm) to show you how simple this is to understand.
Two things I’m very excited about arrived at the farm this week. First is the endomycorrhizal fungi I’ll tell you more about later. The second are the first of our Cascade and Centennial hop rhizomes! They’ll go in our freshly cut beds as soon as the weather permits.
Half Hill Farm is the only farm in Tennessee providing a local source of USDA certified organic hops (certifying April 2013). The Tennessee Department of Agriculture stopped keeping records of Tennessee’s hop production sometime before Prohibition when machine harvesting began concentrating the nation’s hop production in other states. The USDA could find no records of commercial production in Tennessee.
Half Hill Farm is proud to serve the needs of a growing craft beer culture in Tennessee that celebrates an American craft spirit of community, ingenuity, and sustainability. If you are a local craft brewer and want to visit our farm, get in touch, and grow with us!
