Some lovely morning and pre-storm picture taken by Brian Yorck.....Thank you!

In many of these photos you see the dramatic skies...but the drama is really happening below the surface of all of these wonderful cover crops.  

Cover crops are typically a grain or legume that are grown between high value crops (vegetables in our case).   These diverse crops break cycles of pests and disease that can build up over many years of growing vegetables. They also cover the soil keeping erosion at bay during heavy storms.  They keep nutrients in place with their roots as well as by absorbing them into their plant material.   Legume cover crops work with microbes in the soil to fix nitrogen from the air bringing it into the soil!!!  

So as you enjoy these dramatic skies...ponder the complexities of the natural world and the richness that diversity gives to our soils and our lives.

Oats and Peas

The oats are just heading up this week. Chris decided to turn in some oats and peas this week in order to prepare the ground for summer vegetables. We plant the oats and peas into ground that we plan on using late summer to early fall. Cover cropping is a practice which not only prevents water and wind erosion, it feeds the soil as well. There are many different types of cover crops, but oats and peas are nice in the spring because they are quick growing and can handle the early season cold snaps. The peas are a legume, which means that they fix nitrogen.

Here are some pictures of the nodules created by the rhizobia (nitrogen fixing bacteria)that are growing on the roots of the peas plants. They are the slightly pink small round things attached to the roots. The soil is teeming with many different types of rhizobia and when the peas roots begin to grow, they attract the particular rhizobia that will work with the pea plant, in a process called symbiosis, to fix nitrogen. Each legume has a compatible rhizobia and if your soil does not have the correct match, nitrogen fixation can not happen. Our soil has the right rhizobia judging by the pictures. It is possible to purchase rhizobia called inoculants which you mix with the seed to insure symbiosis.
The nitrogen is already present in the air spaces of the soil. The gas moves through the nodule at the root and then is converted by the rhizobia into amonia which the plant uses. The plant in return provides energy to the rhizobia...as much as 30% of the plants captured energy goes to feed the rhizobia.


When the plant flowers it release the rhizobia back into the soil and focuses it's energy on seed formation. The rhizobia can live in the soil for up to three years if soil conditions are right.

We turned in this small section of oats and peas before the flowering time because we needed the space. The rest of the oats and peas we hope to let mature and combine so that we have seed for next years cover cropping.

Chris is using the Soil Saver to turn in the oats and peas. It will take two passes over the course of a few weeks to kill this crop. It will take another few weeks for the organic matter to break down into fine enough pieces for the vegetable seeder to not get clogged up.
