Organic or Chemical Growing? The Pros and Cons
We welcome Mr McGregor of Notcutts to Reckless Gardener. Mr McGregor will be writing a regular column of advice and tips and this month looks at the chemical versus organic question.
As a keen gardener I am always asked if using chemicals is as bad as everyone says and if organic growing is truly the best way to produce healthy yields. I am neither for nor against the use of chemicals, I do avoid artificial fertilisers, but use fish, blood and bone.
I don't use pesticides, but in some cases I use herbicides. The main problem many gardeners have to contend with is slugs. In the past I have used those intrusive blue slug pellets, but have now found and use an 'organic' slug pellet that in my opinion, works equally as well.
I am not against chemical products as it was science that produced a revolution in farming and food production. The introduction of chemical fertilisers in some ways are responsible for the increase in the food supply each farmer could produce.
In theory NPK balanced fertilisers cured weak crops, herbicides decimated weeds that were competing for water and pesticides dealt with those pesky creatures we found feeding on our food supply.
However, in many cases, the theory behind it and the results did not coincide with each other. Farmers and gardeners alike, unknowingly polluted watercourses as the soils were overdosed with nitrogen, plants lacked the micro-nutrients needed to produce healthy crops and pesticides not only killed the plant's foe, but it's friends too.
Nowadays, we have the choice of both chemical and organic products, which allows us to become a smarter gardener with consideration for Mother Nature as well as our produce. When it comes to organic growing you're effectively working alongside nature. Without the use of chemicals, gardeners will find they have an army on their side, earthworms will breakdown the soil and aerate it and the predators will eat those pests that love to feed on our crops.
The Pros and Cons of Chemical Fertilisers
. The main problem is the result of applying too much or an over-application of this class of fertilisers
. What’s left over tends to travel into groundwater, streams, lakes and the ocean, due to rain or irrigation. This pollutes the natural environment and has caused a great number of problems
. If used correctly, they have also proven to be beneficial and safe for food crop production
The Pros and Cons of Organic Fertilisers
. The natural environment tends to have an easier time of breaking down and absorbing organic fertilisers
. There are a few types of organic fertilisers that can pollute ground water and other water systems
. If used incorrectly animal manure can cause many problems. There is a high concentration of nitrogen in manure, which can be released when exposed to water, such as rain and irrigation systems
. There can be an increase in biological activities in the soil when using organic fertilisers
. Micro-organisms help plants convert nutrients into food. The breakdown of old plant material can also be assisted by these micro-organisms, contributing to the overall health of the soil and garden
. Popularity of organic growing is on the increase, which could result in the misuse of this fertiliser
The chemical VS organic issue is a complex one and one that’s neither right nor wrong. It’s all about the individuals’ preferences and beliefs.
If you’re deciding about which road to take to suit your style of gardening, I would suggest you read further into this debate. There is so much information out there and I’m sure with a bit of time you’ll find what works best for you and your garden.
Happy Gardening, Mr McGregor
