Quick, simple and accurate reading of the content of plant available nitrogen in wet and dry manure. Accuracy as lab.-test. The test takes 5 minutes and the result is given in kg N/m3 or lb N/1000 US gallons. The equipment contains reagent for 50 analyses. The equipment also contains a dry matter and phosphorous meter. On Directions for use with pictures below, you can see how the equipment is handled. The equipment is, during the time, further improved and till now it is delivered to 58 different countries.

We have carried out tests with straw filter during spring and summer 2003. The purpose is to reduce the content of nutrients in drainage and waste water. The straw is supposed to be growth site and deliver energy to the microbs. Energy is a limiting factor for the microbs in drainage water, but the access to nutrients is normally good. The straw has an extremely low content of nutrients, but the access to energy in the form of cellulose is good. When straw is ploughed in the field, you have to compensate for the high C/N-quota in the straw by adding fertilizer to the extent of 30 kg N/ha. Straw, used in a filter, can be ploughed in without adding expensive fertilizer.
