Fertilizing

The UW Extension Nutrient and Pest Management Program has produced this instructional video on determining manure application rates as part of the process in determining nutrient credits from field applications of solid and semi-solid livestock manure. Featured in the video is the process of weighing a manure spreader to determine the net weight of a representative load of manure using portable wheel weighing pad scales.

Fertilizing alfalfa with phosphorus (P) and potassium (K) can increase yield and stand longevity. However, to maximize production and profitability, it is important to adjust fertilizer rates to meet the specific nutritional needs of plants in each field.

You may know people who suffer from math anxiety. They avoid situations where mathematics and calculations are required. However, avoiding math is simply not an option when working with agriculture.

High fertilizer prices for a few years were followed by a wet fall and a late harvest last year. All this resulted in many fields' not receiving all the phosphorus and potassium needed to maintain optimum test levels.

Cornell University researchers evaluated the impact of semisolid dairy manure application rate and timing on the yield and quality of orchardgrass. The study was reported in the Agronomy Journal, March-April 2010 issue.

The organic market is growing in size and scope. In 2008 the sales of organic foods reached $22.9 billion, which represented 17.1 percent growth for the market.
