All of this earth moving we have been doing is to get ready to plant our winter cover crop. We are late in doing this, but the winter rains are late in arriving, so the fates are smiling on us in a weird sort of way.
Cover crops are essential to organic farming for a few reasons. The basic point of a cover crop is to plant seed, not for harvest, but to improve the soil. Cover crops are generally planted and then just tilled under a few months later. This process adds organic material to the soil, fixes nitrogen (an essential nutrient for plants), and prevents erosion. We had originally planned to plant a mix of vetch, legumes and oats, but when I spoke with the guy at the seed store, he highly recommended we just plant organic cayuse oats at first to crowd out competing weeds.
So, right now, we have 750 pounds of cayuse oat seeds sitting in our barn. It’s a lot of seed, not particularly exciting in some ways, but it is the first thing we will actually plant on this property, which makes me do a little happy dance of joy. Before we actually plant this seed, the nicer guys with big machines will disc our property with this amazing looking machine:
The point of discing is to open up the soil for oxygen and water penetration and till under any existing weeds.
Next, they will rip our property with this even more impressive machine.
Ripping is hopefully and probably not something we will have to do often. But right now, there is a clay pan, essentially a hard layer of impenetrable clay, sitting right under our 6-12″ of topsoil. This clay pan will make it hard for tree roots, water or nutrients to penetrate down deep into the ground unless we break it up first. So ripping is a specific farm implement and process for braking up this clay pan.
It’s funny, before we actually moved here and started getting more knowledgeable about soil workings, we were all excited to buy a tractor. And we STILL might buy a tractor. But we have quickly learned that we are surrounded by folks with Serious Machines, and it is easier and cheaper just to rent these machines and operators. It would be silly for us to acquire all of this machinery for our little acres and just use them once or twice a year. Again, I am so glad we moved to an area when agriculture has been a way of life for 100 years.
