Hot 5: China’s Dairy. Rodale Study. MIT Battery. Farmland Rents Return. Biodynamic Farming.

1. China is Industrializing its Dairy

China is in the process of importing 100,000 dairy cows from Australia, New Zealand and Uruguay for the company Modern Dairy which is funded by the U.S. company KKR and other private investors. Existing dairy cows in China are half as productive as those in the U.S. and the nation would like to become self-sufficient in dairy. Consumption of dairy products is rising along with the level of affluence in China’s population.

2. Rodale Study Shows that Organic Farming of Corn Outperforms Conventional In Drought Years

The above photo is from the Rodale Institute Study “Organic Farming Outperforms Conventional, Chemical Farming Based on a 30-year side-by-side trial”. It shows corn in the legume-based (left) and conventional (right) plots six weeks after planting during the 1995 drought. The conventional corn is showing signs of water stress.

Organic corn yields were 31% higher than conventional in years of drought. These drought yields are remarkable when compared to genetically engineered “drought tolerant” varieties which saw increases of only 6.7% to 13.3% over conventional (non-drought resistant) varietiies.

Also, corn and soybean crops in the organic systems tolerated much higher levels of weed competition than their conventional counterparts, while producing equivalent yields. This is especially significant given the rise of herbicide-resistant weeds in conventional systems, and speaks to the increased health and productivity of the organic soil (supporting both weeds and crop yields).

3. MIT Professor Donald Sadoway Has Developed a Cheap Scaleable Battery Which Can Power 200 Homes With One Battery the Size of a Shipping Container

Battery technology advancement is critical for green energy and for farming in remote areas. As climate change increases the cost of storm damage to the electrical grid, less populated areas may become vulnerable to repair neglect, just as cell phone services are dropping calls in some rural areas. Micro-grids are proving cost-competitive for farmers in developing nations of India and Africa as I reported in news here earlier this week.

The problem at the heart of many sustainable-energy systems: How to store power so it can be delivered to the grid all the time, day and night, even when the wind’s not blowing and the sun’s not shining? At MIT, Donald Sadoway has been working on a grid-size battery system that stores energy using a three-layer liquid-metal core, based on floating layers of high-temperature molten metal and salt. He says that what has been a handicap for other types of batteries — namely, that they tend to get very hot during either charging or discharging — is actually a big plus for his liquid version.

With help from fans like Bill Gates, Sadoway and two of his students have spun off the Liquid Metals Battery Corporation (LMBC) to bring the battery to market. The company has received $13 million in government and industry funding.

“With a giant battery, we’d be able to address the problem of intermittency that prevents wind and solar from contributing to the grid in the same way that coal and gas and nuclear do today.”

Sadoway was named by TIME magazine as one of the 100 most influential people of 2012.

4. Farmland Return on Investment Continues to Decline According to Rent-To-Value Ratio

The farmland rent-to-value (RTV) ratio, calculated as the cash rent per acre divided by the land value per acre, is a proxy for how quickly an asset will pay for itself. The roughly 45-year trend reveals a decreasing RTV ratio. If agricultural rents were the sole source of returns from farmland, the farmland would have paid for itself in about 14 years in 1951, but would take more than 33 years in 2007. The regions with the highest RTV ratios are the Northern Plains, Delta, Mountain, and Pacific regions. Since 1999, almost every USDA region has seen a decrease in RTV ratios. Farmland prices are more volatile than rents.

5. What is Biodynamic Farming?

The Biodynamic Farming concept originated with Austrian Rudolph Steiner in the 1920s, who also started the Waldorf School education system. In farmers markets everywhere, I am seeing organic farms tout that they practice “biodynamic farming”.

Biodynamic farming:

  • Is holistic organic farming.
  • Works with the rhythms of nature.
  • Is self-sustaining.
  • Works under a theory of cosmic influences.
  • An astronomical sowing and planting calendar is used.
  • Unifies the relationship between soil, plants, and animals.
  • It requires many years to build healthy soil using manures and composts.
  • Healthy soil in return produces healthier, higher quality food.
  • It requires a diversified farm.
  • It works economically when producers and consumers fulfill each others needs. A good example is Community Supported Agriculture, or the CSA, which was developed by biodynamic farmers.

As an aside, note that one unsustainable aspect of modern organic farming that you may have noticed in the above video and on organic farms that you’ve visited, is the large amount of plastic used (and later discarded) for weed-blocking and greenhouses. Plastic is very important to organic farmers to save weeding labor, help with the soil’s moisture retention, and extend the season for produce.

Are You Getting Your 33 Pounds of Cheese?


In 2009, U.S. cheese availability (a proxy for consumption) stood at 32.8 pounds per person. Mozzarella edged out cheddar as America’s favorite cheese, with the two cheeses together accounting for 63 percent of cheese availability in 2009. Per capita cheese availability has almost tripled since 1970, when it was 11.4 pounds per person. Cheese owes much of its growth to the spread of Italian and Mexican eateries in the U.S. and to innovative, convenient packaging, such as shredded cheese for recipes and string cheese for lunch boxes.


The After-Effects of Agricultural Deregulation in New Zealand

The July 2011 Agricultural Symposium sponsored by the Federal Reserve Bank of Kansas City, brought hundreds of banking and business leaders, government officials and academics together to explore the risks to agricultural profits in the 21st century.

“Recognizing Risk in Global Agriculture” included a Bank of New Zealand presentation titled, “NZ Agriculture – Deregulation 26 years on” by Richard Bowman, Head of Agribusiness. To follow are the parts of the presentation which focused upon 1) What happened in the aftermath of Ag deregulation in NZ following 1984, and 2) Conclusions of the outcome of the policy choice 26 years later. (Mostly positive.) —KM


Effects of Changes in 1984

  • Fertiliser halved to below maintenance levels. After 4-5 years, this started to reduce farm output
  • Non-essential repairs and maintenance and expenditure on new plant and equipment was stopped
  • New land development stopped -and some land, which had been recently developed, started to decline through inadequate follow-up, a lot of this land was un-economic without subsidy
  • Farmers laid off labour and did more farm work themselves. Drawings dropped.
  • This reduction in expenditure had immediate and severe effects on rural service industries and rural communities. For every dollar not spent by a farmer, there were three dollars not spent in rural communities. Many people went onto government welfare support.
  • About 20% of the total debt owed by the farm sector was written-off (through discounting) and about 5% of farms were sold. The withdrawal of government support to agriculture virtually halved the value of land and livestock over night.
  • When government support was first withdrawn, farmers initially acted with disbelief. Then they became very angry and, in 1986, nearly one-third of the farming population marched in a protest to Parliament.
  • Government pledged to continue macro economic reform as the best means to improve international competitiveness in farming. This was a clear signal to farmers to start helping themselves rather than seeking ongoing government support.





  • New Zealand agriculture has found that there is “life after subsidies”. In fact, few farmers now wish to return to the days of government support.
  • New Zealand now has an extremely internationally competitive agricultural sector. Quality is very important. New Zealand is very concerned to maintain its clean, green image.
  • Inflation proved to be a major destroyer of farm profitability. High inflation reduced international competitiveness, thereby reducing returns, whilst increasing farming costs. New Zealand’s inflation rate over the last few years has been considerably lower than our trading partners, and this has further enhanced New Zealand’s competitive advantage.
  • Companies and individuals now have full market led responsibility for production decisions. They reap the rewards and take the risks of their decisions. Business management skills have improved significantly in New Zealand in the market led environment.
  • There is now a much reduced risk of making wrong decisions. Rather than the government picking winners, and supporting particular ventures, decisions are now made by a large number of individuals. The consequences of any one decision-maker getting it wrong is now much less.
  • For New Zealand, additional benefits will come from freer international trade in agricultural products. It remains exasperating to New Zealand farmers that much of the international competition New Zealand faces is from subsidised production.
