Last Monday I received a phone call from a custom manure applicator asking for a contact name at the Ministry of Environment. At first impression this is a bit like a roadside fruit and vegetable vendor inviting the taxman to audit the cash drawer. But after sober second thought my applicator friend was making a wise inquiry. He was getting calls from customers to come and start applying manure to snow covered fields because their manure tanks were at the point of overflowing.
Full tanks are a greater issue than usual this spring mainly due to last fall. Wet and saturated soil conditions kept livestock owners from emptying storages as much as they would normally. Operations with more than one storage tank move manure from full to empty tanks as much as possible, but it still is an educated guess predicting how much empty storage capacity is necessary to make it through to spring. Water lines left dribbling to prevent freezing was an unanticipated necessity.
As most of you are aware, owners of a valid nutrient management strategy as defined in the Nutrient Management Act are not allowed to spread manure from Dec 1 to March 31. Arbitrary dates don't necessarily mean much in the rough and ready business of custom manure hauling, but these particular dates have strong roots in common sense. We do get winter with frozen soils and snow. Most years and in most parts of the province this period coincides with the months of December through March.
The riskiest environment to deal with when applying manure is frozen soil. The probability of manure running off into water courses is huge. Melting snow over frozen ground creates a double hazard and the Ontario government takes a dim view toward surface and ground water being contaminated with manure. I know very few farmers that think it is ok to apply manure onto snow.
This presents my applicator friend and his customers with a significant problem. Applying manure onto snowy fields gives my friend ulcers, but letting tanks overflow is not an option.
Part of writing nutrient management strategies includes a contingency plan. The contingency plan addresses situations like this. What do you do when bad things happen? If manure has to be applied the goal of the contingency plan is to identify and reduce the risk.
1. Choose level fields that are not adjacent to open ditches or catch basins.
2. Solid manure should be temporarily piled far away from water courses.
3. Ideally the field would be in hay, pasture or cover crop. The top growth catches and slows down run-off. A second choice would be wheat stubble or grain corn that was not tilled last fall.
4. Application rates should be one half of the normal rate. The idea is to reduce the nutrient load per acre.
5. Avoid applying if the weather forecast indicates precipitation coming.
6. Common sense also dictates only taking out enough manure to get you through to late April when frozen soils are less of a problem.
7. Drag lines are the only application option, until the snow goes away. Even then they are the preferred method because of reduced compaction.
8. If a contamination event happens contain the spill, report the spill and clean it up. If you do these three things you will not face prosecution. Failure to do one of those three, especially the reporting of the spill exposes you to the wrath of the MOE.
When the calendar changes to April 1 the risk to groundwater remains the same and the date change does not give manure application a green light. I find myself making one point to livestock operators over and over again. Nobody has the right to pollute. It doesn't matter if you have a valid nutrient management strategy or not. If you contaminate water you run the risk of being charged.
Coming back to my applicator friend he was taking a proactive approach by to contacting the MOE to let them know he was going to the field. In one sense he was reporting the spill in advance and in my opinion the MOE would appreciate that effort.
Pioneer has launched a new mobile service platform known as EncircaSM. It is available as an app, which can be used on a mobile device, although a tablet provides the most functionality. Initially there are two offerings for EncircaSM. A free option known as EncircaSM View and a fee based option known as EncircaSM View Premium. The objective initially is to offer real time information at a glance. Future offerings will include prediction models for fertility, pest control and markets.
The following is a summary of the current EncircaSM offerings. Check it out.
