Lots of Organic Matter
There are many and varied opinions on soil, soil management and the use of a wide variety of “Snake oils” to improve the ground we farm.
Here at Revive Agronomy we prefer to stick with the science, maybe the work of Rothamsted over a mere 177 years is a good place to start.
Broadbalk Winter Wheat Experiment
The Broadbalk experiment is one of the oldest continuous agronomic experiments in the world. Started by Lawes and Gilbert in the autumn of 1843, winter wheat has been sown and harvested on all or part of the field every year since then. The original aim of the experiment was to test the effects of various combinations of inorganic fertilizers (supplying the elements N, P, K, Na and Mg) and different organic manures on the yield of winter wheat; a control strip has received no fertilizer or organic manures since 1843. For the first few years these treatments varied a little, but in 1852 a scheme was established that has continued, with some modifications, until today.
In 1968 a rotation was introduced on part of the experiment, so that it is now possible to compare the yields of wheat grown continuously and as the first wheat after a two year break.
The highest yields are now from the first wheat crop in rotation, with the best yields from fertilizer alone exceeding those from FYM alone, and the combination of FYM + 96 kg N /ha (144 kg N /ha since 2005) often exceeding both.
What yields are achieved?
The lowest, around 1.0 t/ha the best around 12.5 t/ha.
