Why is crop rotation important?
Crop rotation is important because it has to take into account a whole farm approach. Every farm is unique in its physical landscap and climates as well as its own needs of cropping and feed, also differing management systems come into play.
Cropping most importantly defines the potential maximum income, factoring into the equation is the cost to grow the crop, differing fertiliser needs, chemical needs, soil types, seed costs, cultivations and risk. All of those costs add up....
A healthy fertile soil cycles organic material and releases nutrition to the plant at a time the plant requires it, a soil in a biologically depleted state is unable to do this, the soil/plant/root interaction is less efficient leading to a cascade of issues that need outside intervention to manage these symptoms.
One of the difficulties in agriculture that surrounds soil fertility is that we are really managing a system and the methods and tools used can be many. This often means that there can be contradictions between groups or companies of what we have in terms of mechanics or product inputs...
UNDERSTANDING COVER CROPS
Intensive agriculture has over time accelerated the decline in organic matter. There are many reasons why this has happened, but two particular inputs have been the main drivers over recent decades. The first is the heavy reliance on artificial nitrogen to carbon and the second is around continual oxygenation of soil via cultivation. There are many other contributory factors, including the continuation of these systems over many years. As soil organic matter depletes so does the food source for aerobic biology...
Understanding the basics of nutrition.
Nutrition includes all factors taken from soil and biologically available nutrients, applied forms either as in an inorganic form such as N:P:K compounds or organic sources such as manures and compost and certainly not to be forgotten, non-mineral atmospheric elements such as hydrogen, carbon and oxygen.
Nutrition in most cases of intensive farming in this age cannot be sourced from just one factor either from the soil or being supplied as compound or manure...
UNDERSTANDING ORGANIC MATTER
We hear so many talks about building organic matter. The thing is, there is very little cohesion in understanding the soil system and its consequences. The simple fact is that in a biologically active soil, just growing crops can increase soil organic matter. However, applying organic material into, as an extreme example, a poor lifeless compacted soil can actually be a detriment rather than a benefit.
Natural systems that have developed over thousands of years are described as ‘climax climatic conditions’...

CROP PRODUCTION MAGAZINE : FEBRUARY 2018
Mike Harrington features on pages 42+43
'Soil: it supports the vital power source behind crop production. So how has it also become degraded to the point that it’s only productive through inorganic inputs?
According to Mike Harrington of Oxon-based consultancy Edaphos, modern farming practices over the past 70 years have encouraged the use of artificial inputs on crops, but this hasn’t involved replacing what’s lost from the soil.'...
