Watershed Matchup #2: Clear Creek VS Clear Creek

Watershed Matchup #2: Clear Creek VS Clear Creek

This post is part of a series for 2019 Watershed Awareness Month, comparing water quality in a pair of local creeks to learn how land and people influence water. Clear Creek @Hyland on May 18 Clear Creek@ Hyland on May 24 Transparency > 60 cm Transparency of 1 cm Orthophosphate 0.1 mg/L Orthophosphate 5 mg/L Clear Creek was true to its name on May 18 when the Squaw Creek Watershed Coalition did its spring water quality snapshot.  Long-time member Ed Engle and three Ames High School students (Wil, Becca, and Nate) filled a transparency tube to the top (60 cm) and the secchi disk at the bottom was clearly visible.  A week later, Rick Dietz tested the same location after a 1.7 inch rainstorm and couldn’t see the disk until he’d poured out all but 1 cm of the water! Water quality can change rapidly.  Sediment* in the water spikes during and after a big rain storm.  So does phosphorus and E. coli.  Nitrate and chloride show strong...

Cover Crop Week: October 14-20, 2018

October 14-20, 2018 is Cover Crop Week in Iowa! As harvest continues (if the rain ever subsides), you will start seeing green in fields again.

Cover Crops Can Pay! – Environmental Defense Fund Study Concludes Financial Benefits

Cover Crops Can Pay! – Environmental Defense Fund Study Concludes Financial Benefits

A recent study published by the Environmental Defense Fund outlines the financial benefits of cover crops in a row-crop operation. This, coupled with the environmental benefits, creates a practice that is both practical and vital to our state. This study used an agricultural accounting firm, called K-Coe Isom, to take an in-depth look at three producer's financial books after using cover crops and no-till. One of the farmers in the study is from Nevada, Iowa and the other two farmers are from Kansas and Ohio. Items that were considered for the study were fertilizer costs, herbicide costs, and crop yields after long-term use of cover crops and no-till. The budget categories identified were revenue, input costs, variable costs, and fixed costs. Key Findings from the study include: Conservation practices can pay. Farmers who adopted conservation practices - combinations of no-till, cover crops, nutrient optimization, and crop rotations - reported a cascade of cost savings throughout their budgets, including lower fertilizer, labor, fuel, and equipment...
