Caring for Soil in Drought

The United States Department of Agriculture Natural Resources Conservation Service provides regular informative short newsletters to anyone who subscribes to this free electronic service. The information below was published in mid-April and contains extremely important facts that should be helpful and encouraging to all gardeners.

"Soil health is always important, but extreme weather in the last few years has shown landowners just how important managing for it really is.

“The vital part of soil is topsoil, which unfortunately is also the part most susceptible to the effects of weather. That’s what makes protecting it so crucial,” said Doug Miller, NRSC Minnesota soil health coordinator.

The top two components of topsoil are clay content and soil organic matter which hold nutrients and water for plant use and growth.

“The amount of clay content is determined by glacier content left behind and cannot be changed, but the percent of organic matter in topsoil can be increased,” Miller said.

One percent of organic matter in the top six inches of soil can hold about 27,000 gallons of water per acre. Increasing organic matter increases the holding capacity for water making your land more resilient to extreme weather.

Even with last year’s drought, landowners benefited from improved soil health.

“There were two farms separated by a road that had the same soils, same crops and same precipitation. While one farm thrived through extreme weather, the other one lost corn plants, soil and water. The variable here was the management of the land,” said Miller.

Landowners are the managers of soil, so it’s important to use practices that help protect and improve your soil, he added.

NRCS identified four principles that help improve soil health.
1. Keep soil covered as much as possible.
2. Use plant diversity to increase diversity in the soil.
3. Keep living roots in the soil as long as possible.
4. Disturb the soil as little as possible.

Managing for soil health can help increase productivity and profits, decrease inputs and improve sustainability for farms and ranches.
“We need soil to be productive not just this year, but five years from now, 20 years from now, 60 years from now, and that starts with soil health,” Miller said.

Obviously, this newsletter's primary audience is farmers. However there are some very serious take-away points for the gardener. 

POINT 1 above. Keep your garden soil COVERED with organic mulch.

POINT 2 Avoid single crop row crops. Plant in wider beds. Interplant flowers and vegetables, perennials and annuals.

POINT 3 Remember that perennial plants' roots are living through the winter in undisturbed soil. About 30% of the roots die over the winter which provides nutrients to the soil.

POINT 4. DO NOT TILL YOUR SOIL. Prepare individual holes for started plants. Mark the row with a hoe or grubbing knife. MULCH the rest of the area.

Drowning In Tomatoes? Try Something Different This Year.

 

If you’re a home gardener about to drowned in tomatoes rolling in off the vines and demanding to be consumed before they go bad, hang on. Here comes a life preserver.


I chop up a small bowlful of fresh very ripe tomatoes, add chopped red onion or scallions, minced garlic, chopped fresh basil, and extra-virgin olive oil.  I sometimes add Kalamata olives. I make this dish in the morning and let it set on the kitchen table all day. By evening meal time, the flavors have melded nicely, and I serve it over hot cooked spaghetti noodles and top it with fresh grated parmesan for an easy meal on a hot summer day.
