Food growing facts you may not know.

Do you know that plants grow exponentially?

Let me explain.








Plants are programmed to double in size every few days and with growth come the various stages: germination, maturity and reproduction.

The first stage of growth is not normally seen. It is when the seed sends out roots whose job is to collect food for the plant so that it can grow. At every stage of the plant's life thee is an equivalent growth of roots under the ground as there is volume of leaves and stalks above the ground.

Once the plant has established its life support root system, it starts to grow above the ground. A plant may double in size every three or four days. When the plant is tiny, you don't notice a great change. A plant that is one centimetre tall is very little different from a plant that is two centimetres tall. However, the same growth rate occurs for the plant's whole life cycle. In the same time period of 3 - 4 days that it took to grow from one centimetre to two centimetres, a plant that is 15 centimetres tall and 10 centimetres across, will grow to 30 centimetres tall and 20 centimetres across and if that plant is programmed to start producing fruit or seeds when the plant gets to be 15 centimetres tall, that fruit will grow in those same few days. A broccoli head will double in size every couple of days for 6 or 9 days and then will start to produce flowers.

The speed that plants mature and start to produce edible fruit, leaves and seeds catches most new gardeners by surprise. It seems to take so long for the plants to start looking like the vegetables they planned to grow, that they think it is going to take forever for them to produce edible food.

Wrong! Plants mature in a very short space of time and there is only a relatively short period of time for harvesting. Zucchinis, for example, double in size overnight if left unpicked and quickly become more like torpedoes than food.

At our community farm, I see many of our new members totally surprised to find that they have missed their harvest. The vegetables that seemed to take so long to grow rapidly matured when they just weren't watching! Troy and Shona, in the picture below, keep a close eye on what's happening in their own personal vegetable gardens at the Castelen Community Farm and harvest a bountiful supply of vegetables ever week from just a tiny plot of land. This is just one of the advantages of being a Community Farm member.














If you want to take full advantage of your garden's produce remember to visit your garden regularly, pick the delicious vegetables that are ready and eat them as soon as possible because the nutrient value of vegetables starts dropping as soon as they are picked. You'll be amazed at the difference in taste between a just picked cauliflower and one that has been sitting on the supermarket shelf for a week.

How to increase the profit from your garden or small farm

How to increase the profit from your garden or small farm NOW! (growing vegetables, fruits, nuts, berries or herbs).
As the world population escalates, food prices will rise. This trend will be reinforced by rising oil & gas prices (mainstream agriculture is dependent on oil & gas for transport, fertilizers, herbicides & pesticides). Therefore there is a great business opportunity in growing food. Over the past 18 months, I have been doing a study that takes over 100 of the main food crops and assesses and compares their profitability. This is a brief discussion paper giving you a preview. Clearly more money will be made growing the most profitable crops and this study provides you with over 100 crops ranked in terms of profitability. The crops are also categorized according to their climate suitability, so you can find for example which are the most profitable crops in the tropics, temperate or cold climates. What then are the key factors that affect profitability when growing crops? Clearly your choice of crops is fundamental to your financial success. The other factor you have to evaluate is the market demand for the crops you select and your ability to reach that market. You then need to be able to grow the crops. This subject and an overview of over 140 popular crops is covered in my book called “Growing Healthy” subtitled “How to make over $100,000 p.a. on five acres growing fruit and vegetables organically”. This book is available from the website www.growinghealthyorganicfood.com (see book 1) . For even more detail on growing effectively we have 12 monthly lessons on nature’s twelve universal principles of organic food growing. See course 1 at www.growinghealthyorganicfood.com . The other key topic in assessing profitability is cost. There are capital items like land & equipment & buildings. There are the variable costs of seeds, seedlings, fertilizers, watering, pruning & weeding, soil preparation, planting & harvesting, cleaning & packing, transport & marketing. In most of these there is a labour component and this is generally the big cost. Labour costs vary hugely around the world, where the lesser developed countries such as China & India have a big cost advantage and in the western world USA is generally much lower than say the UK or Australia. These factors and others are assessed crop by crop in my study. But for now here are some quick effective ways to improve your profitability immediately: 1. Temperature has a major impact on growth—too hot or too cold stops growth dead in its tracks for most plants. So if you are in an area that gets extreme hot temperatures (over 30 degrees C) you can improve production by using a shadehouse in the summer. Depending on the size of the area you grow in this can be a small homemade device with cloth draped over wood or plastic poles or a large walk in shadehouse with sprinklers. If you live in cold climates that get frosts or snow, then you can improve productivity and lengthen your growing season by using a greenhouse in the winter. 2. Another key factor that impacts profitability is the length of time from planting to maturity and harvesting. Fruit & nut trees for example typically take 3 years or even longer to bear a crop and then it is often then only a small crop and may take 4 to 7 years before full production is achieved. And then you get only one crop a year from most fruit trees. Fruits & nuts payoff is good longer term as the labour component is lower than for vegetables & herbs. 3. However, if you want a quick return on your investment forget fruit & nut trees. You need to focus on vegetables, herbs and berries. The typical vegetable takes 3 months to maturity. Time and cashflow are major factors in profitability, so how about these:months to grow and many of them can be grown several times a year (depending on the length of your growing season). Some vegetables you can pick many times from the one plant---it just keeps producing! 4. Let’s get specific: (a) Rhubarb is a magic crop to grow. I can pick up to 8 times in a year off the one plant. We have of course a particularly long growing season of 10 to 12 months a year, but even in a shorter growing season area you can pick every 5 to 6 weeks once the plant is mature. (b) There are some other crops that you can pick up to five times from the one plant—namely zucchini, kale and silver beet or swiss chard. (c) The other recommendation is to go for crops with the shortest time from planting Zucchini 7 weeks Radish 7 weeks Silver beet 8 weeks Lettuce 9 weeks Broccoli 10 weeks Carrots 11 weeks The exact time will vary slightly with different varieties and the weather. Conclusion: If you try some of the above recommendations you cannot help but improve your return from your activities on your garden or small farm. At least they will make it easier to cut down on your food bills by selling your excess produce nore readily! However this brief free report cannot cover all the details of growing and marketing your crops. If you want more I have recently produced a short 12 week program that does all this. It is now available as course 2 on the home page of our website: go to http://www.growinghealthyorganicfood.com/course2. This program provides a comparative analysis of the profitability of over 100 crops including helping you set up a step by step business plan to maximize the return on your land size and specific climate. This training program also gives you the use of a profitability calculator where you can input your own figures to calculate the specific profitability of a crop you grow in your climate, with your local pricing and local cost of labour and the growing time of the particular variety that you have chosen.

What are the most important minerals?

Creating and maintaining a healthy balanced soil is crucial to success in growing crops organically. The father of soil science is Professor William Albrecht who studied soils all around the world all his life. He demonstrated that in terms of volume the major elements are calcium, magnesium and potassium. Nitrogen, phophorus and silcon are also significant.
Later research shows that volume is not the only important factor. Individual elements whilst small in quantity can be essential catalysts to the many chemical/biological processes that take place in plants such as photosynthesis. There is a heirarchy of elements needed for these processes to work in plants and this might also apply in humans. (I have added the most common natural food source for us in brackets).
Sulphur is necessary as a catalyst for all the reactions that begin with boron and end with potassium. This is apparently the biochemical sequence of nutrition in plants. The 8 elements in sequence are:
1.Boron (lettuce)
2.Silica (brazil nuts)
3.Calcium (broad beans & watercress)
4.Nitrogen (cucumber)
5.Magnesium (Beans, poppyseed & spinach)
6.Phosphorus (Beetroot)
7.Carbon (vitamin C)
8. Potassium (Lettuce)
There are 92 elements that make up the earth and the human body and not a lot is known about all the minor trace elements. I believe they all play a role and as an example who has heard of yttrium? This element created a three-fold increase in the lifespan of test animals!! Yttrium is found in cabbage, lettuce and tomatoes (if grown in soils that contain yttrium). Lettuce should contain many of the above important minerals and has become one of my favourite foods!!
