MANURE TRAINING FOR APPLICATORS AND FARMERS

Preparing for the Upcoming Season

By Nate Severy, Agronomy Outreach Professional

This winter we have been very busy putting together workshops and meetings focused on new manure spreading rules and how farmers and custom applicators can make them work on their farms. Manure or other “agricultural wastes” cannot be spread within 25 feet of a stream and 10 feet of a ditch. There are also new restrictions when spreading in floodplains, training requirements, and recordkeeping requirements. Everyone under the certified small, medium or large farm definition must spread manure according to a Nutrient Management Plan (NMP), and all farms must apply manure based on agronomic rates.

We received a grant last fall from the Vt. Agency of Agriculture, Food and Markets (VAAFM) to develop an educational and certification program for custom manure applicators in coordination with the Northwest Crop and Soil Team. This program will be very similar to the Pesticide Applicator Program: applicators will have to take and pass an exam, recertify yearly, and accumulate 8 hours of professional development over 5 years to maintain the certification. The first exam will take place next winter, most likely before Christmas.

For this upcoming cropping season, even though custom applicators will not have their applicator certification, these businesses will be expected to follow all of the RAPs pertaining to spreading manure, including keeping application records. To help everyone learn about the RAPs and what records need to be kept, we helped organize 3 custom manure applicator workshops and 5 farmer and custom applicator employee workshops throughout Vermont. At these events, attendees learned about the new rules and what is expected from them. These workshops also provided a forum where people were able to ask questions and engage in open dialogue with VAAFM staff. At each meeting there were good conversations that generated important questions and it is great to hear respectful conversations. Even when people do not agree they can still have a good discussion. We are here to help applicators sort out their questions about the RAPs and will continue to keep the dialogue going.

Going into the 2017 cropping season, I believe that recordkeeping is going be a big obstacle for many people. Good recordkeeping takes extra time, patience, and dedication, even on a small farm. If someone is not prepared, recordkeeping could be challenging for a custom applicator that spreads manure on thousands or even tens of thousands of acres on many different farms. At our meetings, we stressed that the key to good recordkeeping is to seamlessly integrate it into your business. Some are already doing this through technologies like UVM’s goCrop™ or flow meters where fieldby-field data is automatically recorded and downloaded into a computer. Other people have put recordkeeping logs on the back of employee timesheets and require that the employee fill out the log in order to be paid. For custom applicators who need help with recordkeeping, UVM Extension has developed a recordkeeping book (copies available at our office). Each page has a carbon copy so at the end of the day the applicator can fill out the page, tear off the top and give it to the farmer for his/her records, and then tear off the carbon copy and put it in a file at home. All of these systems are acceptable, but it is important to use the system that will work best for you, and will help strengthen your business going into the future. Even though there is an initial inertia required to make record keeping successful, the hope is that it can also pay off for the farmer by documenting and improving on agronomic practices.

If you have questions about manure application or would like more information or materials on record keeping, contact our office. If you do not have an NMP and need to obtain one, contact your local conservation district or NRCS office for funding possibilities.

Manure and Cover Crops

Manure and Cover Crops…A Winning Combination

by Kirsten Workman, Agronomy Outreach Professional

Fall applied manure is often a subject of concern – for farmers, water quality advocates and even the general public. As you know, most farmers have the conundrum of having ideal field conditions for spreading manure in the fall (dry, open, great weather oftentimes) and a need for making sure they have adequate winter storage, but not wanting to lose out on the nutrients in that manure.. Especially producers who farm heavier soils with higher clay content, that try and avoid as much spring tillage as possible. If you are a no-till farmer, you know even better that fall applied manure without incorporation will not yield much of that nitrogen for you next year’s corn crop. You can lose up to 90% of your ammonium nitrogen with the right (or rather wrong) conditions.

So how do we make the most of fall applied manure… plant a cover crop, of course!! Fall applied manure as part of the establishment of a cover crop can be a win-win. Not only do you better utilize your manure, potentially doubling the amount of nitrogen retained, but your cover crop will perform better too. This all leads to better soil coverage, less erosion, better nutrient cycling, and lower fertilizer costs. Not a bad deal!

Last fall, we conducted a small demo/experiment at the Farm at VYCC in Richmond, Vt. Although this is not ‘scientific research’ per se, we did utilize a randomized split block design with three different treatments with and without manure. On October 2nd, we seeded 100 pounds of winter triticale per acre with different treatments of ‘Purple Bounty’ hairy vetch…either 10, 20 or 30 pounds per acre with the triticale. Five days later, liquid dairy manure was broadcast over half of all the plots at a rate of around 4,000 gallons per acre. We then measured percent cover one month later in November 2013 and then collected forage samples to analyze nutrient content, measured biomass, and re-measured percent cover on May 15th, right before the cover crop was plowed down. We found that the plots that received manure out performed those that didn’t in all aspects that were measured. Not surprisingly, a fertilized cover crop does better!! Plus you have better utilized your fall manure. The manured plots had double the biomass, double the nitrogen and phosphorus and potassium, and roughly one and half times the soil coverage in the fall and spring.

These plots have now been plowed down and were planted to ‘Early Riser’ corn (an 80 day flint/dent variety) on June 7th. No starter fertilizer was applied, and PSNT’s will be taken to make a recommendation for nitrogen later in the season.

There is more to come on this topic. This fall will be commencing a two year research project that will investigate combinations of winter rye and tillage radish (in comparison to straight winter rye) established with diary manure. We hope to determine if the addition of the radish in manured systems can amplify winter rye’s effectiveness as a winter cover crop. We also hope to determine the most effective seeding rates and establishment methods.
