Which Pastures Should You Work on Improving When You Have Limited Resources?

Researchers comparing high and low fertility soils in Wisconsin pastures, concluded that the best chance of getting a return on fertilizer expenses is when soil fertility is low at the start. As you know, manure is really the key source of nutrients for grass-based farms, and since it's basically free, researches found it showed the greatest net return on investment. But when adding nutrients, it's easier to raise a pasture you might grade at a C- to a C+ or B-.  Working with the A or B, though there's less room to improve, so you won't see quite as much bang for your buck. Katama Farm: an example of limited access to fertility If you have really limited abilities to improve soil health, where should you put your resources? I've been considering this ever since a consulting visit to a farm on Martha's Vineyard. The solutions one farm er has come up with can give you an idea of how changes to your management can help your under-performing pastures. Jon Previant manages Katama Farm, (pronounced "Kuh--Tay-Ma") raising beef, sheep, and chickens. The farm is also home to the Farm Institute, an organization dedicated to connecting people of all ages with a working farm. Katama Farm, like others on the island, has the challenge of sandy soils that don't hold a lot of nutrients. Sitting on the southern shore of Martha's Vineyard, no bridge connects the island or Katama Farm with the rest of the world. Every item needed on the island comes over on the ferry, so boost

  1. We are in the same position in northern Ontario Canada. We ammed with spent grain from the local micro brewery (24% nitrogen , small amounts of minerals) and feed it to our chickens and Cows who move it around for us. We spread it in areas the cows wont go to for a while and mix in wood chips (carbon) from the local fire wood processor. we put down approx 10000 lbs a week and in a year have covered 15 acres of pasture.Still going strong. We have noticed a strong return in flowering plants and grasses, and a reduction in mosses and thick spindly plants. Some people will disagree with feeding the SG to cows but its at their choice and they come running. Its a free way to amend the pastures and we saw a greater return in it than liming sandy soil. Good luck!

  2. G’day, generally speaking poor pastures are a result of deficiency in the soil/sub soil.But instead of applying the necessary elements to the soil why not feed a ‘complete mineral mix”(recipe provided on request) directly to the stock?Our soils are more acid than the ones stated but by approaching the problem differently we have overcome the majority of the problems associated with it as the stocks improved health shows.Another strategy we employed was to fence out a small area(about 1 ac)at the intersection of say 3 paddocks and allow the grasses there to flower and seed for at least 1 year,only grazing at a non-critical period to replenish fertility from the stock.This little paddock will reward you with seeds carried by wind ,stock and wildlife to the adjoining paddocks and so over time increase diversity of species in the surrounding paddocks
    Has the farmer ever considered a “deep litter system” in the barn? Instead of continually cleaning out the bedding ,why not just add more?The decomposing bedding generate heat in the process and by the end of Winter it is almost all composted and you only clean it out “once”.Frank.

  3. If you have the same soil type across the grazing areas, it makes cents to get the least fertile up to optimum. It there is variation is soil type and productivity I’d focus on managing my best soils to their capacity first, before focusing on lower quality soil.

    soil pH. If it’s that costly to import liming material, why not grow a legume such as trefoil which can tolerate a lower pH?

    1. Look into biochar additions to deep litter and over standing forage in areas of low PH. Well made char acts like an anchor for nutrients and a flywheel for micro-biota. Steps up the livability to microbes and holds onto nutrients when trampled in. It can be made on site if there is debris clean up to be done by burning.
