Field lab - Soil microbes to improve yield
Twin N is a selected formulation of freeze dried aerobic and entophytic microbes which utilise free atmospheric Nitrogen. It is claimed that it will improve yield, plant health and profit.
Stephen Bosustow of Trerise Farm, Cornwall heard of a number of producers using this product with mixed results and wanted to know how it would affect his crops in terms of both yield and profitability. As such he decided to apply Twin N and Kelp to the majority of his crops while leaving distinct patches untreated. He would like to see if the cost of product (£60.30/ha) is returned in measurable yield terms.
The trial has already been established, so our first meeting in the series of three took place on 13 August. The second meeting took place on 24 September, with the final meeting taking place on 12 November.
This field lab is being hosted by Stephen Bosustow of Trerise Farm, Ruan Minor, Helston, Cornwall TR12 7NA.
Twin N is a selected formulation of freeze dried aerobic and entophytic microbes which utilise free atmospheric nitrogen. It is claimed that the microbes function like millions of tiny nitrogen fertiliser factories, colonising the root zone and entering soil spaces too small for plant roots. Once inside these micro-spaces, they fix atmospheric nitrogen and produce gasses that create pressure within the soil structure. The resulting increased friability improves water and air movement within the soil.
The manufactures say that Twin N forms a particularly useful synergy when used with FYM and/or slurry as the manure stimulates the multiplication of the Twin N microbes. It is also claimed that Twin N works well with clover and other leguminous crops by increasing the number and size of the nitrogen fixing nodules which ought to benefit both the growing crop as well as the residual stable N in the soil for following crops.
Through discussions with other users, and with prior consent from his Certification Officer, Stephen mixed Twin N with Kelp (the Kelp is meant to give the Twin N a feed stock to speed activity and multiplication of microbes) and applied this mixture at a rate of 1l/ha Twin N + 10l/ha Organic Kelp to a mixture of crops (Pea & Wheat, Grass & Clover and Fodder Beet). Each visit and subsequent report will give an update of the status of the crop trial along with key observations by attendees, the farmer and facilitator, and pictures showing any particular points of interest.
