quantifying labor

i spent an hour by the clock this morning threshing winter rye...pulling seed heads off the stalks and aggressively rolling them between both thumbs and index fingers...and being repeatedly stabbed by awns...goes with the territory...that hour of threshing got me 1 1/4 ounces of rye seed and awns and chaff ( yes i zeroed out the scale to negate the container's weight before i weighed the product )...another ten minutes of winnowing the grain and i had netted 1 1/8 ounces of clean rye seed to add to what has already been done...a total of 3 3/8 ounces so far, or about three-and-a-half hours of work..so...what's the result of that work? ( and there is more to do ) we ( because this will be going into the community garden too ) get w winter cover crop that is locally produced ( my back yard is as local as i can get )...it will also act as a reservoir for nitrogen th egreen manures that are planned for the garden will produce...two thirds of those seeds ( winter vetch and dixie clover ) will come form stands i grew in my yard as well ( i have not quantifies the labor for those...the winter vetch is simply a matter of splitting open the pods and dropping seeds into a container...about a thousand seeds to an ounce...not tremendously time consuming and i have 5 1/8 ounces of seed...more than enough for our purposes....dixie clover is far more intricate [ particularly when you have clumsy fingers ] and the returns far smaller in quantity of seed...that's another post ) the yet...field peas i purchased as well as inoculant for the bacteria to set up the symbiosis...we are not completely independent...yet...the good news is once a rizobia colony is established in a bed it can survive for up to five years without the introduction of host plants...if we use green manures every year we should only have to inoculate the beds once...more independence...i will be planting stands f all these plants this late summer to grow more seed...the process continues...so does the work.
