These represent one of our oldest and most highly evolved technologies – starting from a digging stick.
Adapted to the internal combusion engine they were the primary driving force for the post-war Green Revolution but machines don't produce manure and are harder on the ground – compressing it and making it harder to plough. Over the decades since, soils have become depleted of organic matter and more effort is needed to plough them and more fertiliser is needed.
In recent years, farmers across the world have been backing away towards minimum dig approaches – pushed also by rising fuel costs and the availability of herbicides. If we continue down the herbicide path we need to develop ones that are easier on soil life that makes up about four fifths of the land biomass.

This article, Energy and Atmosphere, looks at the energy dynamics of the Earth's atmosphere. Since the role of radiative
gasses has become a political issue that is undermining the stability of industrial
economies and denying the many benefits of cheap and reliable energy to billions of people, the
precise nature of the energy dynamics of our atmosphere has become a trillion dollar question.
It shows a new derivation for the adiabatic temperature lapse rate in the atmosphere.
It also points to a possible explanation for why the Earth's water thermostat cuts in so suddenly at 30 Cº.
The IPCC and the Carbon Cycle
We are told by the IPCC that CO2 emissions from burning fossil fuels are causing atmospheric CO2 levels to rise and that these are causing global warming. Of the two links in this chain of reasoning this article addresses the first.
I show that the IPCC view of the carbon cycle is fundamentally flawed in many ways, and is not supportable at any meaningful level of confidence. This is not esoteric science to be left to specialists or ‘great minds’. Any numerate person who cares to look and think can understand the insignificance of our total industrial era CO2 emissions at less than 1% of the carbon cycle and our annual emissions at just 5% of the air-sea fluxes.
The article Radiative Delay in Context challenges a core assumption of the contemporary climate science consensus, that the Greenhouse (or Radiative Delay) Effect is the sole mechanism by which the Earth's atmosphere raises the Earth's surface temperature above that which would exist without an atmosphere.
In it I show that the Radiative Delay heating of the atmosphere is negligible, and a well established alternative mechanism arising from atmospheric buffering over the diurnal temperature cycle is capable of producing the temperatures we experience.
The role of Carbon Dioxide is shown to be negligible.
This is a personal view of the political nature of the CO2 scare from an environmentalist who has watched on in dismay at the extreme politicisation of the environment. I watched the takeover of the environment movement since the 1970s by the extreme left acting with motives that have nothing to do with reducing our environmental impact.
Moving forward we see the actions of the totalitarian left in the United Nations and associated NGOs forming the Intergovernmental Panel on Climate Change (IPCC), and how this has perverted the already corrupted nexus between science and public policy.
