New Resource: Potash Video & Potassium Cycle Poster

Wednesday, February 12th, 2014
The Nutrients for Life Foundation is proud to provide its latest free education resources: The Potash Mining Video and Potassium Cycle Poster. Every plant needs three basic elements to grow nitrogen, phosphorus, and potassium. Potassium (K) is important to plants because it acts as a regulator. It helps plants efficiently use water, transfer food, and protect against structural stress. If a plant is deficient in potassium, it is much more susceptible to stunted growth and disease. K is found naturally in soil, but sometimes must be replaced, especially after years of growing plants on the same land. So where do we get the K in fertilizer that provides all these great benefits? From mining potash in deposits of ancient evaporated inland oceans. To learn more, watch The Potash Video:   Also, check out our new Potassium Cycle Poster available free through our website. It is so meaningful for science classes to expose students to natural biogeochemical cycles, such as the potassium cycle. Even if students are unable to recall every aspect of the potassium or phosphorus cycle months after your class, the concept of the cyclical nature of earth’s major resources is an essential concept for tomorrow’s generation.   Mineral weathering, plant residues, animal sources, and fertilizers supply K to the plant roots. In some soils, mineral weathering primarily supplies enough potassium to provide sufficient amounts of K, with help from plant residues, biosolids, and animal sources. However, continual use of the soil for crops or gardening can deplete potassium faster than natural weather and other sources can replenish it. Runoff, erosion, plant harvest, and leaching can be causes for potassium loss. In those cases, potassium fertilizer can restore amounts. We hope these new resources invigorate your soil science lessons and are a helpful addition to your classroom! Keep up with the Foundation- Facebook | Twitter | Pinterest | YouTube 

Kids in the garden: I can’t keep them out!

Friday, June 28th, 2013
I cannot keep these two girls out of the garden! They want to plant, weed, and harvest, and thankfully the plants aren’t affected by all of the noise they make. The chatter goes something like this: “Can we pick the broccoli?” “Is this one a weed?” “It’s my turn to use the hoe!” “I can’t see it?” “Why is there a flower?” “What’s that?” “Is that a spider?” “Where did it go?” “How many seeds can I have?” “That’s a prickly weed! How did it get prickly?” “I’m thirsty.” This week, I actually got whacked by the hoe while getting drilled with questions. I was pulling weeds, and my four year old insisted on helping by hoeing in the same row. Ouch! Apparently, there are hazards when gardening with kids.  Honestly, I love it! I am glad to have this time to teach through the garden. (more…)

How to Harvest Rhubarb for Strawberry Rhubarb Pie

Thursday, May 26th, 2011
Five years ago I planted rhubarb so that today I could enjoy a fresh rhubarb strawberry pie - one of my favorites! During the first three years, I sparingly harvested a few stalks, enough to satisfy my taste buds. To establish the perennial rhubarb plant it’s important to allow the crown and roots to grow without heavy harvesting. (more…)
