Farming is increasingly dependent on technology, which means the world of crops is becoming more mechanised.
The global food supply, however, is far from being fully mechanised, and in some places the situation is worsening.
We examine how the food we eat is grown, the technologies used to grow it, and the consequences for the planet.
In this episode we examine the use of fertilisers in agriculture, and why some crops are better for human consumption than others.
Fodder Crops Grow Faster, but How Much?
In the past, the most efficient way of growing crops was by using machines that could be used to do the job, but we now know that these machines are getting smaller and cheaper.
Fertilisers, however are also changing the way we grow crops.
Fungicides, which kill off beneficial bacteria and fungi, are becoming more and more common in agriculture.
But while they may kill off a few beneficial organisms, they don’t necessarily kill all of them, so farmers are using a different approach to grow their crops.
They use chemical fertilisers to increase the growth of beneficial organisms.
In most countries, fertilisers are applied to fields in the early spring, but in parts of Europe they are applied at harvest time.
In a recent paper published in Science Advances, researchers at the Max Planck Institute for Evolutionary Anthropology, Germany, analysed the impact of this technology on the growth rates of plants.
In some cases, fertiliser application had no impact on growth at all.
But in other cases, the impact was dramatic.
The authors found that a large proportion of crops grown with a fertiliser applied to them were actually worse for human nutrition than the same crops grown without the fertiliser.
The researchers concluded that this was because fertiliser applications to the crops had increased their nutrient content by a factor of more than two.
This increase in nutrient content can be attributed to the use in the field of a chemical fertilizer that increases the level of phosphorus in soil.
However, a growing body of evidence suggests that fertiliser usage may not necessarily increase the level and therefore the quality of soil, or the amount of nutrients in the soil.
In fact, the fertilisers themselves are actually doing more harm than good.
Fertility is also affected by fertiliser use, and fertility problems have been reported across the globe.
In the United States, for example, fertility rates have been dropping.
In Australia, fertility has been falling in recent years as people have stopped using fertility-enhancing drugs.
And in many developing countries, fertility problems are particularly severe.
The effects of fertiliser overuse on fertility are becoming increasingly well understood.
For example, in South Africa, where the rate of fertility decline has been particularly bad, the government is considering making fertiliser-based fertilisers mandatory for all farmers.
And, in India, a fertilisers ban was recently introduced, which has led to a decline in the fertility of some farmers.
In many cases, farmers are also using fertiliser on their crops in areas where the land is unsuitable for crops.
In other countries, such as Australia, China, and India, farmers use fertiliser to fertilise crops in the late spring, and then wait for the soil to dry out before applying fertilisers.
However in the United Kingdom, where fertiliser fertilisation has been phased out in the 1990s, farmers have been using fertilisers on crops for decades, and are now beginning to use fertilisers more frequently.
Why is the Fertile Pools Growing So Fast?
The growth of the world’s fertility pools is driven by factors beyond technology.
Famine and disease have reduced fertility in many parts of the globe, but they have also reduced fertility around the world.
This is partly because they have increased competition from other species.
So far, there is little evidence to suggest that this increase in competition has had a negative effect on fertility in developed countries.
But a recent study from the University of California at Davis found that in areas with poor sanitation, poor nutrition, and poor water quality, fertility is declining faster in some countries than others, and that in countries with better sanitation, improved nutrition, improved water quality and improved soil fertility, fertility was increasing.
This suggests that some factors are causing a downward trend in fertility.
The reasons for this decline are not completely understood.
One theory is that fertility is becoming less efficient as technology improves, and is therefore being lost more rapidly in poor countries.
In contrast, in countries that are getting better sanitation and nutrition, fertility may be increasing.
Other factors are contributing to the decline in fertility in poor and developing countries.
One of the most dramatic changes in fertility is the increasing use of pesticides and herbicides.
In recent years, many countries have switched to a new generation of herbicides that are less toxic and more efficient at killing pests and weeds.
In addition, farmers in poorer countries are increasingly using chemical fertilizers on crops that have never been used before.
This has led some researchers to argue that fertility in the
