Greenhouse in the city

So this young woman commented about having a greenhouse on a vacant lot in Norwich (the main city in the East of England).  I wrote back that the first thing she needed was to obtain a soil sample to ensure the soil was suitable.

When we bought the farm we had over 500 samples taken all over the farm to establish the ground quality, especially since the farmland had been partly abandoned for the past decade. 

She said that at ₤100.00 it was too much, and I said, that since most of the sites in the city of Norwich are brown, in that they have been previously used, it is important to know that there are no heavy metals or other dangerous chemicals in the soil.

Her reaction was amazing, she was very keen on having a biological garden but really didn't worry about the soil in which her tomato plants would draw their nutrients.  I said, you will be using raised beds for your tomatoes and other greens, but the reality is that you need to know what is in your soil, and what is missing.  Each vegetable thrives, as an example, in a slightly different level of alkalinity and if you are using manure you should be aware that not all manure is equal.  It is not only to know if there are poisons in the soil but so that you know what to add and when.  

It's actually funny, how city people think that raising food is easy and simple, that we don't test our soil and that we don't draw exacting analysis of all our production.  City folks would be amazed by the level of technology involved in modern farming, especially when you want biologically certified production.  Do we increase the amount of chicken manure to add natural nitrogen, potassium, phosphorus and calcium, which is higher in chicken manure than in cow manure? Some of the manure used on the farm doesn't go in the biodigester for that very reason.  Before buying the new farm we were contemplating adding a lot of manure on certain fields that we wanted to dedicate for corn sillage, but now we have excess pasture.   Now we don't need to do that.  

Until now it's my wife and I who spent the majority of our time planning for the farm's forthcoming growing season, we start with what we need for our growth objectives, weather and historical production and then plan our planting strategy for the spring.  This year, this will change a bit with the addition of the new farm manager (she's moving in the new year but is already on the job and has for a whole week) and will therefore plan with her assistance (frankly she comes from a professional background, and there is now software to help farm manager with this process).

Ok so I lied...a little (revised)

When we began looking at farming in 2013/14 as something we both wanted to do as a "second career" we invested time and money to understand what sector of farming was profitable.  A few things emerged, First, high-quality, source-proven, organic farm products consistently have much higher profit margins.  Secondly, transformation accounted for nearly 80% of total profits, and production and distribution accounted for 20% of profits: Farmers and retailers have low profit margins and the middle bits make all the money. A profitable farm operation needs to be involved in the transformation of its produce.  The low-hanging fruits: cheese and butter.  Milk, generates a profit margin of 5% to 8%, depending on milk quality.  Transformed into cheese and butter, and the profit margin rises to 40% (Taking into account all costs).  Second:  20% of a steer carcass is ground beef quality.  The price is low, because (a) a high percentage of the carcass, and (b) ground beef requires process

21st century milk parlour

When we first looked at building our farm in 2018, we made a few money-saving decisions, the most important is that we purchased our milk herd from a retiring farmer and we also purchased his milking parlour equipment.  It was the right decision at the time.  The equipment dates from around 2004/05 and was perfectly serviceable, our installers replaced some tubing but otherwise, the milking parlour was in good shape.  It is a mature technology. Now, we are building a brand new milk parlour because our milking cows are moving from the old farm to the new farm.  So we are looking at brand new equipment this time because, after 20 years of daily service, the old cattle parlour's systems need to be replaced.  Fear not it will not be destroyed instead good chunks will end up on Facebook's marketplace and be sold to other farmers for spare parts or expansion of their current systems. All our cattle are chipped, nothing unusual there, we have sensors throughout the farm, and our milki

So we sold surplus electricity one time last summer...(Update)

I guess that we will be buying an additional tank for our methane after all.   Over the past few months, we've had several electricity utilities/distributors which operate in our region come to the farm to "inspect our power plant facilities, to ensure they conform to their requirements".  This is entirely my fault.  Last summer we were accumulating too much methane for our tankage capacity, and so instead of selling the excess gas, that would have cost us some money, we (and I mean me) decided to produce excess electricity and sell it to the grid.  Because of all the rules and regulations, we had to specify our overall capacity and timing for the sale of electricity (our capacity is almost 200 Kw) which is a lot but more importantly, it's available 24/7, because it's gas powered.  It should be noted that the two generators are large because we burn methane and smaller generators are difficult to adapt to burn unconventional gas, plus they are advanced and can &qu
